Tesla: What’s New?

Model Y Tesla

Model Y, Tesla’s car of the future.

“Elon Musk is still at the forefront as a founding father of the rapidly changing electric car industry.”

By Linn Smith
November 26, 2017—-When I happen upon a Tesla owner charging their car at a charging station, as I did recently in Trinidad, Colorado, I usually linger long enough to ask the owner his opinion of the Tesla. The responses are always similar, “Best car I ever owned,” or “Most fun car I ever had.” The people who own the Teslas are the best advertisement for these all electric vehicles. Some of the reviews I have read on line are mixed, but testaments “straight from the owner’s mouth,” have been strongly positive!

Tesla: A Review

The Tesla Model S was introduced in 2012. Several revisions in 2017 have improved the driving range per charge to between 270-335 miles. The 40-amp charger of earlier models was replaced in 2017 with a 48-amp charger, which enables a quicker charge and about 30 miles drivable time per hour of charge.

What’s New for Tesla in 2018?

*The Model S 100D has a range of 335 miles with the ability to hit 60mph in 2.5 seconds (if you’re into speed).

The Model 3, with a base price of about $35,000, reportedly is, “Adopting a controversial plan to forgo prototype tooling (a test model design) in an effort to accelerate the launch of the Model 3.” Test drivers, journalists and financial analysts were given hands on demonstrations of the car and loved it! 

AllianceBernstein says, “We found the Model 3 to be a compelling offering, and believe it is likely to further galvanize the overall Electric Vehicle category.”

Though Tesla has struggled getting the Model 3 available to the public, it promises to be available soon. Tesla’s target of producing 5,000 Model S’s by the end of December has been pushed to March of 2018.

All electric semi will change the way cargo is hauled across country.

The Tesla Semi

In the meantime, Musk has unveiled his electric semi-truck and Roadster sports car this week, and may unveil an SUV, Model Y soon.

Tesla will be the first user of their semi-trucks, hauling cargo between its California factory to one in Nevada. “Tesla will be the first customer for the semi. We will use our own truck to carry cargo in the U.S. between our different facilities. We have an assembly facility in California, the Gigafactory in Nevada, so we will use our trucks to carry things in-between.” This electric semi has a range of 500 miles on one charge, which is approximately the round-trip mileage of 80% of the trucking market. The price of the electric semi would compete with the sale of regular gas semis.

The Model Y (Unofficial name) will be a small SUV, which was going to be built on the Model 3 platform but is now back to the original plan in building it separate in order to bring it to market sooner. It will be a more automated production line, bringing it to market faster, as SUV’s are one of the fastest growing vehicles.

So, Elon Musk is still at the forefront as a founding father of the rapidly changing electric auto industry, with the other car manufacturers scurrying to keep pace with his Tesla company! Tesla has confronted many obstacles, but still moves ahead to combat our warming climate.

Climate Change Over Geological Time

Glacial Ages and Climate

Climate Change Over Time

“Climate change at the present is of great consequence to most species including humans.

By Dr. John J. Hidore

November 15, 2017—-Planet Earth was formed about 4.5 billion years ago. Geologists have divided this long history of the planet into several pieces called eras. They are the Precambrian, Paleozoic, Mesozoic, and Cenozoic.

The Precambrian is the longest and each of the other three are shorter than the previous one. When considering climate change through geologic time, two aspects stand out. The first is that for most of geologic time Earth has been warmer than it is at present. How much warmer varied through time. The second feature that stands out is the intermittent ice ages when large portions of the earth were covered with ice.

Major Ice Ages

Relatively little is known about the long period of Precambrian time. Basically it was the period during which the earth cooled from its initial very hot state. The Paleozoic, Mesozoic, and Cenozoic eras encompass the rest of geologic time, about 570 million years. More evidence, and a greater variety of
evidence, is available about the environment during these eras. The climate of Earth varied widely during this time. However, it has been established that there were three known periods of glaciation in Precambrian time. They were:

Archeozoic 2250 million years ago (mya)
Early Precambrian: 950 million years ago
Late Precambrian: 750 million years ago

There were four major glaciations following that of the Precambrian era. They were:

Early Cambrian: 650 mya
Ordovician: 450 mya
Permo-Carboniferous: 350-250 mya
Pleistocene: 1.8 mya until recent time

Following the ice age at the end of the Precambrian, the earth rapidly warmed. For the remainder of the history of the earth, temperatures have averaged 5 degrees C (9°F) higher than at the present. These warmer conditions existed probably 90 percent of the time over the past 570 million years.

The Permo-carboniferous Ice Age

An ice age, called the Permo-carboniferous, began at the end of the Paleozoic Era. It began about 325 million years ago and lasted until about 250 million years ago. The South Pole was in the midst of the large land mass called Gondwanaland. Ice sheets moved over about half of this large land mass. What is now Antarctica and parts of Australia, India, Africa, and South America were covered with ice. The glaciation of each of these areas did not take place at precisely the same time, but they were all affected by the same climatic cooling. The Southern Hemisphere suffered widespread glaciation, but the Northern Hemisphere remained warm. The most appealing explanation for this situation is a different relative location of the land masses. The northern continents were nearer the equator and the southern land masses nearer the poles.

Climate Change

Climate Change over time.

The Warming of the Earth

After the glaciation in the Permo-Carboniferous ice age, the earth again entered a long period of warm conditions. The period of warmth continued through most of the Mesozoic Era and the earth was free of glaciation. Temperatures were warm and rainfall was abundant on the land masses. Even the polar regions experienced mild weather. Initially, the warmer conditions resulted from the slow migrations of the large southern hemisphere land mass to the north. This carried areas that had been glaciated into warmer climates.

The Pleistocene Ice Age

The most important single environmental event since the human species has been on earth has been the oscillation between glaciation and interglacials during the Pleistocene Epoch. The epoch represents a large change from much of the last 570 million years. This ice age is the most recent of the major cold periods to occur over the history of the planet. During the time when the ice was most extensive over Earth, temperatures averaged about 4°C (7°F ) lower than those of the present. In the northern hemisphere it was perhaps 8 to 12 °C ( 14 to 22°F) lower than current temperatures. 

There is no question but what the climate of planet earth has changed frequently, and sometimes drastically, over geologic time.

Climate Change Today

Climate change at the present is of great consequence to most species including humans. There is really no way of knowing how much change will take place in the foreseeable future nor how much is due to the activity of our species. What is known is the earth is warming rapidly at this time and that all evidence points to human activity as bearing the responsibility.

Now is the time to take international action and not only support the Paris Agreement, but take even more drastic measures to curtain the warming!

Puerto Rico: Rebuilding Sustainably

Renewable Resources

 

“Building sustainably in Puerto Rico can take many different forms.” 

By Linn Smith

October 19, 2017—Even though Puerto Rico is going through a devastating time after the hurricane, it is essential that we not only meet the current needs of the people, but also think about its future….rebuilding sustainably. Areas devastated by wind and flooding must not only think about immediate needs, but consider the future way climate change may threaten vulnerable coastal areas. 

There is an agreement among scientists that our warming climate is producing larger, more aggressive hurricanes, and rising oceans are leading to stronger storm surges, destroying and flooding inland areas.

Puerto Rico: Sources of Energy

According to the U.S. Energy Information Administration, Puerto Rico has some renewable solar, wind, hydropower and biomass resources, but relies primarily on imported fossil fuels to meet its energy needs, importing mostly from the U.S.

In 2016, Puerto Ricans paid more for their power than people in any other state except Hawaii, with 47% of electricity coming from petroleum, 34% from natural gas, 17% from coal and only 2% from renewable energy.

The Future of Energy in Puerto Rico

Now is the time to make decisions about Puerto Rico’s future energy needs. How will Puerto Rico get its power in the future? PREPA, the Puerto Rico Electric and Power Company, Puerto Rico’s only utility company, is mismanaged and highly in need of upgrading according to some sources. According to http://www.commondreams.org, it would be a waste to pour more money into this system. Instead, we need to invest funds into local renewables and energy efficient transportation, such as streetcars and light rail trains. 

Richard Heinberg in the article “Disaster in Puerto Rico” stated, “This is a chance to build back sustainably. People tend to maintain their status quo as long as it’s viable, but when in dire straits, they’re more likely to listen and when denial is no longer possible, people are more likely to face reality.”

Eigg renewables

Eigg uses 99% Renewable Energy

Eigg, Scottland: 99% Renewable

According to an article by David Nield, March 2017, http://www.sciencealert.com, researchers from around our planet are visiting the tiny, Scottish island of Eigg, which is using wind, solar and hydo to obtain the island’s power. This system, owned and operated by the island’s residents, has been using sustainable energy since 2009. Eigg Electric uses a combination of sustainable resources to ensure there is always energy. When back-up energy is needed, it’s supplied by several diesel generators with cables linking all the sources of energy together. Renewable energy is used 95% of the time and excess energy is stored in a bank of 100 batteries. When these batteries are full, electric heaters automatically switch on in the church and community hall so nothing is wasted. Eigg’s population has doubled since this system has been in place, but the system is still meeting the needs of the residents. The drawback is that citizens are limited to the amount of power they can use daily from the public utilities
.
Ta’u, a small island in Samoa, is also changing from diesel to renewables. Today it’s powered by 5,000 Solar City solar panels and 60 Tesla Powerpack battery storage units. The Powerpack is a massive battery, 16 Powerwall battery pods encased in a weatherproof box, that can store electricity during the day when supply is abundant and discharge it when demand goes up after the sun goes down. This system provides the island with about 99% of its needs.

Tesla solar project in Hawaii.

Tesla and the Powerpack Battery

Tesla has also built a huge solar energy plant on the island of Kauai, one of Hawaii’s main islands. This project will reduce fossil fuel by 1.6 million gallons per year. The island signed a 20 year contract with Tesla to buy solar generated electricity from solar panels installed on the island for 13.9 cents per kilowatt hour. The average price of electricity in Hawaii is 37.34 cents per kwh, the highest rate in the nation. Kauai is the first major solar/storage project for Tesla. Tesla states, “We will work with energy providers around the world seeking to overcome barriers in the way of building a sustainable, renewable energy grid of their own.”

Tesla is also in the process of shipping battery packs to Puerto Rico, but details of the project have not yet been made available. Building sustainably in Puerto Rico can take many different forms and accepting help from Tesla could be a starter.

Living Green: Using Our Resources 

building green

Cities, states and individuals must do their part in preventing climate change.

Remember: Recycle, Reduce, Reuse!

By Linn Smith

October 12, 2017—-People in developed countries are losing the ability to be resourceful! We “run to the store” impulsively on a daily basis. How did folks survive without today’s conveniences? Today nearby stores provide us with our every need, and we too often toss excess and unused products in the garbage, leaving our landfills and oceans overloaded with toxic materials that may never decompose!

Growing up on a farm, we grew most of our own food. Our basement was lined with many shelves containing hundreds of jars filled with colorful, canned foods from our garden. Cows, pigs and chickens provided us with fresh meat, and our dairy cows provided the milk we drank, and it wasn’t pasteurized! My mother strained the milk through a cheesecloth to get the big chunks (of whatever) out…..and my brothers, sisters and I all grew up healthy! Farm life was what we call green living today….but back then it was just life!

Families use to be resourceful. To obtain something they needed, they reused, fixed, mended or created something new from what they already had.  My grandmother created children’s mittens from old sweaters, it saved money and no new items were purchased.

Earth Day: Let's Clean and Green!

Earth Day today and every day!

Eco-friendly Steps to Going Green

What are some eco-friendly steps we can take to conserve today? Here are just a few:

1. Turn some of your yard (or all of it) into a garden and can or freeze the vegetables. Yards were originally for very wealthy families in England, who used sheep to keep the grass trimmed. Lawns weren’t meant to look like  golf courses. They had dandelions and clover. Today our lawns are toxic with chemicals and leave  huge carbon footprints!

2. Buy unpackaged products from local farmers at farmer’s markets.

3. Cook from scratch instead of buying processed food. It tastes better!

4. Make restaurants an occasional option, not a daily trip. (This includes Starbucks!).

5. Buy second-hand from used stores, garage sales, or auctions. Fix, mend or make-do.

6. Don’t buy more than you need. Several years ago we stored most of what we thought was our valuable “stuff” and went RVing. It cost well over $1000 to store. When we returned and assessed our “stuff,” we realized we could live without most of it. We had a garage sale, making several hundred dollars from the sale of our valuables that had cost over a $1000 to store!

7. Recycle and compost.

Earth Day

Clean Energy: Make It a Priority!

Why Not Go Green?

Here are some excuses people make to avoid helping our planet:

1. It’s too expensive…BUT, if you shop around most things are comparable.

2. One person can’t make a difference….YES, you can! Good thing everybody doesn’t feel this way!

3. No one else around me is living eco-friendly…..WELL, THEN….how ’bout you be the first!

4. It’s too late. The planet is already doomed….OK, pull your head out of the sand and look around at what positive people are doing!

5. Global warming is a myth. NO IT’S NOT! (But I won’t waste my time arguing with you on this point!)

6. It takes too much time and effort. It’s like anything else, it becomes routine when done on a regular basis.

Before you buy something, ask yourself if you really need it, or is there something you already have that could be used…or ask, Can I make do with less?

The Carbon Footprint of Air Conditioners

“The world’s supply of A/C units could increase from about 900 million in 2015 to roughly 1.6 billion by 2030.”

By Linn Smith

August 20, 2017—-If solar airplanes can fly, then maybe it’s time we look at solar for our air conditioning. According to a 2016 study at Berkeley National Laboratory, nations with emerging economies and spiking populations, including heavily populated India, are seeing air conditioner sales grow 10 to 15 percent a year.

What does the increase in air conditioning mean for our warming planet? The world’s supply of A/C units could increase from about 900 million in 2015 to roughly 1.6 billion by 2030. The Berkeley study says new technologies must take the place of hydroflourocarbons, (HFCs), found in most air conditioners. HFCs are growing rapidly in our atmosphere with a potential to increase the greenhouse effect faster than carbon dioxide, because they trap heat in our atmosphere at levels 1000 times greater than CO2.

Sierra Club

Sierra Club for Clean Air

Rwanda Climate Conference

In 2016, 200 nations gathered for the United Nations summit meeting on climate change. Negotiators created a deal to ban the use of HFCs in air conditioners and refrigerators, with finalization at the Kigali, Rwanda climate conference a few months later. 170 countries successfully negotiated an amendment to the Montreal protocol treaty to get rid of 90% of the HFCs. Developed counties will begin phasing out HFCs in 2019, China in 2024, and India and other counties in 2028.

Nearly all HFCs are made by a few giant western chemical companies, including Flame Guard USA in Illinois, GMC Aircon in South Africa, and OB-1 Air Analyses, Inc. in California.

Cities, states and individuals must do their part in preventing climate change.

Reducing HFCs

The search is on for clean technologies to take the place of HFCs. In Australia, the Solar Hybrid Air Conditioner is offered by the company, EcoWorld. EcoWorld claims you can stay cool without the huge energy bill. This unit costs about $2700AU or $2000 U.S. dollars. You can see it at http://www.ecoworld.com.

They state:

1. Hands down this is the cheapest-to-run 3.5kW Split System Air Conditioner you can buy.
2. Stay Cool or Warm without the huge energy bills. Use it more often without regrets.
3. Pays for itself, in energy savings alone, within 7 months of running time.
4. Runs automatically between both Solar DC Power and 240V AC Mains.
5. 12000 BTU Performance without costing the earth.
6. As the sun goes down it transitions over to the mains power supply.
7. Comes with a 6 Year Australian Warranty when installed by a certified air conditioner installer.
8. Rated to cool or heat around 30-40 square meters.
9. Filters pollen particles from the air and can also dehumidify your space.
10. Helps to reduce Greenhouse Gas Emissions back at the power station.
11. Highly efficient and feature packed 3.5kW split system inverter air conditioner.
12. Uses 1kW of solar panels (typically 4 x 250W panels in series).
13. When running together with the solar panels it uses as little as 30W of 240V AC mains power which is virtually nothing compared to standard air conditioners.

Can we wait until 2019, 2024 or 2028 to cut HFCs? Will it be too late? Now is the time to take a step towards saving our planet! New technologies must replace fossil fuels and chemicals, such as HFCs, that contaminate our atmosphere!

Reduce HFCs in our atmosphere.

The Galapagos UNESCO Heritage Site in Danger

Galapagos islands at risk from climate change

Home to many rare species of plants and animals

“In 2007 UNESCO listed the Galapagos as threatened, as a number of the most unusual creatures found on the islands were in decline.”

By Dr. John J. Hidore

August 11, 2017—-The Galapagos Islands are located about 600 miles west of the coast of Ecuador. There are 13 major islands in the group, in addition to dozens of smaller rock outcrops. They were discovered in 1535 by sailors engaged in exploration. These islands are a unique treasure on our Planet.

The Galapagos Islands have been designated a UNESCO Heritage Site. When explorers first described the islands to people on returning to their home ports, most people did not believe the stories that were told.

The Galapagos Islands are significant for a variety of reasons. First, there is no other island ecosystem like it. They are home to many species of plants and animals not found anyplace else on the planet. The animals include blue footed boobies and marine iguanas. Second, it is the setting for the work of Charles Darwin in formulating the theory of evolution that was published as The Origin of Species. Charles Darwin visited the islands in the year 1835. At the time, the islands were known as Las Encantatas or the enchanted ones.

Galapagos Islands and climate change

Galapagos animals and plants are at risk due to global warming.

Climate Change is Altering Life on the Islands

Global warming has already raised the temperatures over the islands. The islands generally receive little rainfall. Parts of the islands depend on cool season fog to provide condensation for plants. Additional warming may eliminate this weather pattern which is the only source of moisture for vegetation is some areas. Increased rainfall that may come with a changing climate may also lead to the decline in many species of plants.

The warmer conditions are causing vegetation zones to move to higher elevations. The rising temperature is also affecting the ratio of males to females in some turtles. Warmer temperatures tend to produce more female offspring, a phenomenon that has been observed at different locations around the world.

The mean temperature of the surrounding ocean of the islands is rising. Like other regions that lie astride the equator, coral bleaching has now been observed to occur in the reefs around the islands. The bleaching is an indication of not only global warming of the atmosphere, but of the warming of the tropical oceans. While corals live in warm water they will not live in water that is even a few degrees above their optimum temperature range. As the ocean warms they are also expected to become more acidic. This will increase the rate at which minerals are dissolved from the reefs.

Sea level has been rising and is expected to rise even more. The only question is how much more it will rise. Estimates of sea level rise by 2100 vary  with the highest estimates rising 30 inches. Rising sea level may destroy many of the mangrove forests which are home to some unique species of birds including some species of finch.

Galapagos Islands and climate

Galapagos Islands are at risk due to climate change

Invasive Species

There is a second problem which may be a greater threat than climate change to the uniqueness of the islands. This is the introduction of plants and animals not native to the islands. It is believed there are now more than 1400 introduced species on the islands of which more than half are plants.

Many of the introduce species have been accidentally introduced. Probably among the first were rats, which jumped ship over the years. The rats thrived and the population grew rapidly. Many other species of insects and plants were probably introduced at the same time. The accidental introduction continues as other species of plants and animals come to the islands along with the importing of merchandise.

Other species of plants and animals have been deliberately introduced. Among the first were domestic goats. They were often kept aboard ship for the purpose of supplying meat and milk for a ship’s crew. On the Galapagos some of the goats escaped to become wild. Their numbers increased and they began devastating the natural vegetation. In recent years major programs to eliminate the goats have been initiated, especially on the smaller islands. In 2006, for example, a massive effort was mounted to eliminate some introduced species from several islands.

Largely due to problems related to the invasion of species, in 2007 UNESCO listed the Galapagos as threatened, as a number of the most unusual creatures found on the islands were in decline. This includes sea lions which depend on a declining food supply off shore. The changing of the plant communities is a threat to many native birds. Some of the very species of finches which were the foundation of Darwin’s theory of evolution are in danger of becoming extinct.

On the plus side, most native species are expected to survive if invasive species can be controlled. But again, additional climate warming may eliminate the weather pattern necessary for plant and animal survival!

Gothenburg Sweden: Providing Sustainability through Green Bonds

Gothenburg, Sweden

Build sustainably with green bonds.

“Local governments wield significant influence and authority that can drive environmental sustainability within their jurisdictions.”

By Linn Smith

August 6, 2017—–In the late 19th century Gothenburg developed into an industrial city. In 1987 the Minister of the Environment called parts of the city, “hell’s waiting room” which described the environment for the industrial part of the city, dirty and polluted. Chemicals were escaping into the environment and appearing in animals, fish and mother’s milk, increasing cancer risks and lowering the immune system of infants. This was the Gothenburg of yesterday!

From Industrial City to Climate Leader

Today, Gothenburg has transitioned from industrial city to a world climate leader. In 2013, it became one of the first cities in the world to issue Green Bonds. 

Bonds allow the public to invest sums of money. When a person purchases a bond they lend money to the issuer of the bond, in this case, the city of Gothenburg. In return investors are paid a specific interest rate. 

Green bonds are linked to solving our climate change disaster by providing the money necessary for a community to build sustainably. They are earmarked for environmental projects.

Gothenburg, Sweden

Go Green with Green Bonds

Building Sustainably with Green Bonds

Gothenburg offers Green Bonds to the public, which allows the city to borrow money from investors. With this money the city creates climate change projects that allow a transition from a polluted city to one of low carbon emissions and climate-resilient growth. Without the Green Bonds Gothenburg would have struggled with decisions on funding schools and daycare or moving the city toward sustainability.

Gothenburg, Sweden

Gothenburg goes green with Green Bonds

Projects Funded by Green Bonds

Some of the projects funded by Green Bonds are:

• Large scale production of biogas, providing high efficiency in production and recycling of waste heat for district heating and electricity.
• Electric cars for city and companies, with 100% electric cars in the city fleet.
• Energy efficient traffic lights
• Sustainable housing. These buildings use green electricity. Estimation shows that the sustainable housing built so far will avoid 50-60 tons of Co2
emissions in the atmosphere annually.
• Tree planting. 1710 trees have been planted since the projects funded by Green Bonds started, with a focus on a green cityscape, which effects the
urban air quality and temperatures of nearby buildings.(See https://planetearth5.com/tag/heat-islands/)
• Sustainable transportation. Improvements to the city’s bicycle infrastructure. The city offers 1,000 bikes with 69 stations in the city to leave
your bike. You can pick up a bike, ride it to your destination and drop it off at the nearest station.
• A sustainable airport. All energy at the Gothenburg airport comes from renewable sources. Heat is generated by biomass boilers. There are also
charging stations for electric cars. Take off fees for airplanes are reduced for those with lower emissions of nitrogen oxides and hydrocarbons. 75%
of the airport shuttle buses run on RME, a biofuel made from rapeseed (related to canola oil.)
• The city’s SJ trains run entirely on renewable electricity from wind and hydro power.
• A sustainable port. Gothenburg is a coastal city. Ferries and ships which are docked in Gothenburg are encouraged to connect to an onshore power
supply, which is a source of clean energy. “Providing an onshore power supply for vessels at berth can result in significant environmental gains.
Carbon dioxide emission decrease substantially and emissions of sulphur dioxide and nitric oxide are reduced to a minimum. Onshore connections also
provide a quieter environment and cleaner working conditions.”
• The largest ultrafilter built in Scandinavia. City water is treated by ultrafilter to assure the highest quality of drinking water for its citizens.

Linking Investments to Green Projects

Green Bond investing has led to greater interest by citizens in the environment, plus it creates a link between investments and speeding up green projects. 

Other cities are following suit. Toronto issued Green Bonds to finance a heat, power and cooling solar plant. Johannesburg just issued green bonds to finance green projects that will reduce greenhouse emissions and contribute to a sustainable city.

The California Sustainability Alliance said it well. “Local governments wield significant influence and authority that can drive environmental sustainability within their jurisdictions” and further influence the global greening of our planet!

A Positive Environmental Impact: Recycling Steel

recycle steel

Recycling steel will make a positive impact on our environment.

“If our government doesn’t support clean technology, then we need to clean up our own back yards to counteract this lack of environmental support.”

By Linn Smith

July 27, 2017—-In June, Acosta mining company opened the first new mine in Pennsylvania in many years, stating that 2/3 of the coal mined would be used in steel production. According to the Pittsburgh Post-Gazette, “It remains to be seen to what extent the coal industry can rebound……the industry will continue to contend with cheap natural gas and clean energy.” Not a mile from the Acosta Mine, clean energy is found! Dozens of wind turbines line the ridges!

Can we produce steel without coal? According to http://www.letstalkaaboutcoal.co.nz, “Making Steel Without Coal”, the answer is no, not at the scale we need at the present time. We produce about 1.6 billion tons of steel worldwide each year. Half of this is produced in China.

To produce 1 ton of steel, .8 tons of coal is used, emitting 2.1 tons of CO2 into our atmosphere. Producing steel and iron accounts for approximately 6.7% of CO2 emissions worldwide. This is a major contributor to climate change!

Coal and steel

Steel making contributes to climate change.

Making Steel

In New Zealand ironsand, a type of sand which has a heavy concentration of various metals, is used instead of coal to produce steel, and New Zealanders have improved on their steel plants by using by-product heat, a method of using the waste heat from steel production. This use of waste heat lessens the contaminates that are put into our atmosphere. Some ironsand is exported to other countries for steel production, but the amount available is not significant.

The most common method of steel production uses coke, a bi-product of coal. The average blast furnace used to make steel needs 800kg of coal to produce a ton of steel! Recycling steel for new products uses 50 times less coal! The average electric arc furnace (used in recycling steel) uses about 16kg of coal. We can reduce the amount of CO2 in our atmosphere by recycling steel products that are no longer used. If our government doesn’t support clean technology, then we need to clean up our own back yards to counteract this lack of environmental support. We, as individuals, can make a conscious effort to recycle, not only packaging materials, but steel.

steel and coal

Making steel causes pollution, contributing to global warming.

Any Grade of Steel can be Recycled

Steel is the most recycled material on the planet. According to Wikipedia, “Any grade of steel can be recycled to top quality new metal, with no ‘downgrading’ from prime to lower quality materials as steel is recycled repeatedly. 42% of crude steel produced is recycled material.”
You can recycle many things that may have seen better days, such as bikes, broken toasters, and cars or car parts.

By recycling steel, you are doing your part to reduce the need for new mined minerals. In fact, two of every three tons of new steel comes from steel scrap.

Recycle Steel: How You Can Help!

The American Iron and Steel Institute has put together some interesting facts about steel recycling. Here are a few of them:
1. Millions of tons of iron and steel are diverted from the waste stream to the recycling stream due to steel’s magnetic properties that make it the easiest material to separate from the solid waste stream.
2. Almost 69 percent of all steel is recycled in North America each year – more than paper, aluminum, plastic & glass combined. North America’s average recycling rate has been in excess of 60 percent since 1970.
3. More than 80 million tons of steel are recycled each year in North America.
4. For every ton of steel recycled, 2,500 pounds of iron ore, 1,400 pounds of coal and 120 pounds of limestone are conserved.
5. Steel products can be recycled repeatedly without loss of strength.
6. Recycling steel saves the equivalent energy to power about 18 million households for a year.
7. When you buy steel, you’re always buying recycled.
8. More than 14 million cars in North America were recycled in 2006.
9. In 2006, the steel industry recycled enough steel from old cars to produce nearly 13.5 million new ones.
10. One scrapped car produces more than four steel utility poles.
11. 95 percent of the steel taken from commercial construction demolition sites was recycled and made into new steel products in 2002.
12. It takes more than 40 trees to build a wood-framed home. A steel-framed home—eight recycled cars.
13. All 99 pounds of steel in the average major appliance can be recycled to make new steel products.
14. Appliance motors are made from steel.
15. Steel comprises approximately 75 percent of all major appliances.

Do your part! Prevent old appliances and steel based products from taking up space in our landfills, where they will still be sitting thousands of years from now!

The Sierra Club and Environmental Defense Fund: Making a Difference

Sierra Club

Supporting our environment.

“A key part of the Sierra Club’s mission is to protect the quality of the human and natural environment.”

By Dr. John J. Hidore

June 28, 2017—–Since President Trump pulled the United States out of the Paris Agreement it has become more urgent for people of this country to become climate activists. There are many ways of supporting action to reduce global warming and the related problems. One of these is becoming a member of an active non-government organization (NGO). This adds your voice to those of many others and contributes to the power of the NGO. Following are two such organizations. I selected these two out of many for the reason that they both are celebrating anniversaries covering many decades. Both have responded strongly to President Trump’s actions to eliminate pollution controls in this country.

Sierra Club

May 28th of this year marked the 125th anniversary of the group. The Sierra club was founded by John Muir in 1892. The first Sierra Club Bulletin was published in 1893. Initially the organization was focused on protecting the mountains of California from wanton destruction by logging and mining. Soon the group became active in the establishment of our national parks. During the 1960’s the federal government was proposing the building of a series of dams on the Colorado River system. The Sierra Club was a leader in the fight to leave the river system in as natural state as possible.
I remember attending a water resources conference in one of the western states and watching the heated debate over the proposed plan. The federal plan was defeated and the government came down hard on the Sierra Club for its part in blocking the plan.

Sierra Club for Clean Air

In 2015, the Sierra Club was rated one of the top 15 most influential brands in Washington, DC. This was based on characteristics of integrity, influence, and respect by policy makers. The Sierra Club was the only environmental organization to make this list. It is now the largest and perhaps best known environmental organization with nearly three million members.

A key part of the Sierra Club’s mission is to protect the quality of the human and natural environment. It is also engaged in educating people on the nature of and problems in the natural environment. It has been actively involved in a number of campaigns related to its mission. Among them are the Beyond Oil and Beyond Natural Gas campaigns. On June 5th of this year, the Sierra Club and other groups filed a law suit against the Trump version of the EPA for weakening protections from oil and gas pollution.

Environmental Defense Fund

A fund for a clean environment.

The Environmental Defense Fund (EDF)

This year is the 50th anniversary of the fund. In 1967 a small group of men gathered at the Brookhaven National Laboratory on Long Island to incorporate the fund. It was formed to challenge the use of the pesticide, DDT. Evidence was increasing that the widespread use of DDT was killing many species of birds. This included large birds of prey such as eagles, osprey and pelicans.

Brown Pelicans had all but disappeared on the coast of North Carolina along with much of America’s coastline. After six years of providing evidence of the hazard of DDT, William Ruckleshaus, then head of the Environmental Protection Agency, banned the use of DDT in the United States. Some other countries have now also eliminated the use of it, but it is still widely used worldwide and is still manufactured in the United States.

EDF: for a clean environment.

When I lived in Khartoum, Sudan, DDT was routinely sprayed in the gutters along the streets to keep down mosquitoes, but on the plus side, I am happy to report that now when I go to Wrightsville Beach in North Carolina I often see large flocks of brown Pelicans soaring overhead or skimming the waves.
Today the EDF is working on a variety of projects around the world in climate, ocean fisheries, ecosystems, and human health.

Solar Uses in the West: Monitoring the Irrigation Ditch

Solar monitors the flow of water.

“It’s predicted that in the future, solar will be the main source for controlling our water systems in the West.”

By Linn Smith

June 23, 2017—In the eastern section of the U.S., water is easily obtainable. In the west, where dry land prevails, water rights are taken seriously.

How is water diverted to arid land? Irrigation ditches are man made channels that deliver water to homes, farms or industries. They have head gates on creeks and water sources to divert water to these arid regions.

Water Rights

In the West and Southwest U.S., a person diverting water through a canal needs legal rights, because there are many demands on the water between individuals, industries and cities. In the 1800’s miners depended on water rights for mining of gold and other minerals, and pioneers depended on water rights to irrigate crops far away from the stream.

Colorado developed the Prior Appropriation Doctrine which is still in use today. It states that, “The first person to divert water and apply it to a beneficial use has a prior or senior right to the water over any other user who seeks to use water at a later time.” This secures the amount and date of senior users. Water rights in Colorado are property rights and can be bought, sold or rented apart from the land through which they run, if the water is put to beneficial use.

In New Mexico a person needs to obtain a permit through the State Engineer Office. The office will evaluate and determine if water is available and would not impair existing water rights.

Irrigating

In New Mexico I helped surface irrigate (flood irrigate) a friend’s ranch from an irrigation canal, which ran above ground. Irrigating consisted of opening the irrigation gate by hand and allowing water from the canal to run over the horse pasture. We were able to control the amount of water on the pasture by sliding the gate down when the water was sufficient for healthy pasture growth. This has been the most common type of irrigation in most parts of the world.

Solar Powered Water Moniters

Recently a solar monitor was added to an irrigation ditch nearby, which runs through farmland and continues to a large lake. The gate of the irrigation ditch was previously open and closed by hand, but now a solar monitor opens and closes the gate to prevent flooding from unused water in the ditch.

In an article, Solar-Powered Automation on Irrigation Delivery Systems, it states, “The most popular do it yourself solar automation model consists of a 1/16 inch horsepower gear motor, a bicycle-type lift apparatus, (chain and sprocket) and a cover over the gate stem which contains a gate position sensor and limit switches. The gate system is usually powered by 1 or 2 deep-cycle batteries which are charged by a 20-40 watt solar panel. The gear is attached to the 12 volt DC gear motor with an industrial chain.”

It’s predicted that in the future, solar will be the main source for controlling our water systems in the West, from pumping up groundwater for cattle to monitoring the amount of water in irrigation ditches. Again, sunshine prevails!
