In Defense of the Clean Water Act: The Supreme Court Decision

Hawaii Wildlife Fund

The Supreme Court defended the Clean Water Act

“We are glad the Court has recognized the importance of protecting clean water for all Americans.” David Henkin

By Linn Smith

On April 23, 2020 the Supreme Court, in a 6-to-3 ruling, rejected arguments concerning Maui County Sewage Plant in Hawaii (County of Maui V. Hawaii Wildlife Fund) and the Trump administration which stated only pollution discharged directly into navigable waters requires permits. The Trump administration had previously filed its interpretation of the Clean Water Act saying, “The law does not apply to discharges that travel through groundwater before reaching protected waters.”

Hawaii: Protecting the coral reefs

The Clean Water Act

The court held that the Clean Water Act “require[s] a permit if the addition of the pollutants through groundwater is the functional equivalent of a direct discharge from the point source into navigable waters.” The Supreme Court clarified the Clean Water Act, which now requires permits for groundwater pollution running into oceans, lakes and rivers.

Environmentalists point to the once natural, living reef off of Hawaii’s coast that has been destroyed by the nearby waste water plant. The Supreme Court holds polluters responsible saying they must be held accountable for not only waste water discharged directly into lakes, oceans and rivers, but also into groundwater that eventually finds its way to the lakes, rivers and oceans.

Maui’s Wastewater Plant

Maui injects 3-5 million gallons a day of treated wastewater into wells beneath its facility, which lie about 1/2 mile from the Pacific shoreline. Environmentalists injected dyes to trace the flow of the wastewater from 2 wells. The dyes revealed that half of the treated wastewater was entering the ocean from the underground wells, thus endangering the reef.

According to past articles, there have also been many raw sewage spills from Hawaii into the Pacific Ocean in the past few years and, until recent times, it was common for Hawaii to pour raw sewage directly into the ocean without any treatment.

Supreme Court decision

Wildlife Fund vs. Maui

The Supreme Court Decision

The sewage in Maui is treated and, when possible, reused for irrigation. The majority is injected into wells, leaking out and finding its way into the ocean. The question brought before the Supreme Court was whether permits were required for waste water that travels a distance from the polluting source, ending up in the navigable waters.

This decision of the Supreme Court will make it easier for parties to sue polluters for irresponsibly leaking of wastewater into oceans and rivers.

David Henkin, lawyer for Earthjustice said, “The Supreme Court has rejected the Trump administration’s effort to blow a big hole in the Clean Water Act’s protection for rivers, lakes and oceans.”

The case will return to an appeals court, but polluters who dump into groundwater which eventually finds its way to lakes and oceans will now be required to have permits. The ruling also allows some lawsuits to take place against the polluting source. Failing to obtain a permit could result in a fine of up to $50,000 a day.

And finally, an Ansel Adams quote, “It is horrifying that we have to fight our own government to save the environment.”

Gardening and Hydroponics: Learning to Grow Your Own Food

hydroponics

Grow your own food without soil.

“The important thing is you’re learning to grow some of your own food sustainably.”

By Linn Smith

I get it…no one wants to get suited up in masks with sanitary wipes in their pockets, rubber gloves, i.e. donning your suit of armor of choice, to go into a grocery store these days to shop for food, only to bring it home, wipe it down, take a shower and wonder if you were exposed to this horrid Covid-19 virus that’s currently ransacking our planet. Where I live it is now against the law to enter a grocery store without a mask. How I appreciate the good old days when we could make a quick stop at the store on the way home from work and quickly run in to pick up something we needed for dinner!

Yard to Garden
Turn your yard into your garden.

Gardening

Today, there is a run on seeds for planting outdoor or hydroponic gardens at home. Folks are realizing that they may have room in their house or apartment for gardening or they conclude they may not need their entire English style lawns for recreation, instead converting them into gardens for readily available food in a month or so.

From yard to garden
You can grow your own food.

Whether you live in an apartment or have a yard, you can learn to grow your own vegetables and herbs. Many without a yard are getting acquainted with the indoor method called hydroponics, growing small plants without soil, where water provides the nourishment for plants. This type of gardening requires setting up your own indoor garden for smaller plants using seeds, nutrients, containers and a light source. The light source will vary according to the plant.

Kitchen gardening
Turn your kitchen into a garden.

Hydroponics

An excellent guide to starting your indoor garden can be found at www.https://www.thespruce.com/beginners-guide-to-hydroponics-1939215

Aquaponics
Fish and plant dependency.

Aquaponics

Being a teacher I have witnessed several examples in our school system that use aquaponics (a branch of hydroponics) and fish, which not only teaches kids about caring for fish and gardening, but the interdependency of nature, all while finding the benefits of bacteria created by the interdependency. Students learn to create a closed, self-sustaining system which also provides food for them. For more detail see: https://aquaponics.com/aquaponics-in-schools/aquaponics-information/build-a-mini-aquaponic-system/

Food scarcity
Empty shelves at grocery stores.

Food Scarcity

Whether you plant an outdoor garden or try your hand at indoor gardening, the important thing is you’re learning to grow some of your own food sustainably, as there may come a time when the grocery stores are not just sold out of toilet paper, which has been the recent circumstance, but also out of food.

Climate Change and Overconsumption

Sustainable living

“Overconsumption exists when resources are consumed at an unsustainable level as measured by the ecosystem’s capacity.” Pielc.org

By Linn Smith

“Medical researchers and climate scientists note that viral outbreaks may become more common with the progression of the climate crisis, which is affecting the movement of humans, animals and pathoogens.”
Earth Institute/Columbia University.

Sitting here quarantined in Colorado I have consistent reminders to stay home. This isn’t too hard for me… yet…as a green belt along the creek is just a few steps away, enabling me to walk the dog or ride bike for miles. I am also fortunate to have good neighbors that are taking advantage of the same thing….but we do stay 6 ft apart!

Working toward 100% renewables

Making Changes to Save Our Planet

I have wondered if this is the kind of drastic measures we need, not only to stop the spreading virus, but also to make the changes necessary to save our planet. For years I and many others have been preaching ways to consume less. We are now making the changes out of fear and responsibility to save our population. We find ourselves using less because we don’t want to make those dreaded runs to the grocery store or order from Amazon, where warehouse workers have now been diagnosed with Covid-19.

I can’t help thinking that this is the type of fear we need to sustain humanity on our planet in the future…..for those are the beings that are going to be hit hardest by climate change and possible lack of food. Dr. John J. Hidore and I have provided the public with many articles stating scientific facts to support the future outlook of our planet, so I won’t bore you with statistics here.

Landfill

The Arizona landfill

This past winter I have spent many days hiking up the side of a mountain in Arizona, looking over my shoulder at the valley below. Deep in the valley appears to be a sizable mountain, but in actuality it is a landfill made into what appears to be a mountain, radiating toxicity. When I see this site I often think, “We can do better!”

The Effect of Impulse Buying on our Environment

We are an impulse-buying nation with very little thought into the future of how the products and packaging we purchase will eventually be that great mountain of garbage which dresses the landscape in every city, county, state and country. We fail to ask ourselves,”How will what I buy effect our environment in the future?”

I grew up on a farm in the Midwest. We grew and canned our own food, had dairy cows and chickens and were pretty self sufficient. The nearest neighbors were at least half a mile away. I learned to be resourceful and inventive out of necessity. It seems we have lost the ability to use our imaginations, accepting the fact that hopping in our gas guzzling vehicles and traveling to the store is the answer to all of our problems, i.e. our needs and wants. We fail to ask ourselves, “If I want this, what resources do I already have that I might use to make something that is close to what I want?” (This was pretty easy as a kid with a big imagination!) We can ask ourselves, “Can I borrow something that I need? Can I repair something? Can I convert something no longer useful to something I want?” Yes, many of us have lost the ability to create, convert or adapt!

Recycle

Create, Convert, Adapt

If it’s food, can I make what I need instead of buying it prepackaged at the grocery store? For example, I have lived, at least part-time, in the southwest U.S. for many years, beginning my teaching career in New Mexico. There I learned that you can eat just about anything in a tortilla and this habit has stuck with me throughout the years. I recently ran out of tortillas….but I have flour and I know they are very easy to make! (Just for fun here is a song about tortillas that depicts my sentiment exactly. It is sung by Petey Ronstadt, Linda Ronstadt’s nephew. I was fortunate to see him and talk to him a few times in Tucson. For a little entertainment, take a listen https://youtu.be/7-qQJzOq7u8)

So, swinging back from tortillas to climate change, is there something we can learn from these times of turmoil? Can we use less, drive less, stay at home more, borrow, make or ask ourselves, “Do I really need it? If I really do need it, could I buy quality goods that last longer, and have a plan to reduce, reuse or recycle?” The answer is yes. We can do it!

Generating Electricity at Night

solar at night

The new technology would allow panels to generate solar during the nighttime hours.

“The heat engines are made from a different kind of cell than a photovoltaic cell”

Linn Smith

When we think of solar panels we think of the sunshine bearing down on photovoltaic cells used to produce clean electricity. The big drawback has been lack of sunshine, which diminishes their ability to produce electricity during the nighttime hours and on cloudy days. For households surrounded by trees, I often hear the excuse, “We can’t install solar because the sun doesn’t hit our roof, yard, ect.”

There is some recent exciting news! Scientists have discovered a new way that solar can generate electricity with lack of sun and during nighttime hours. Researchers have discovered that if you want to generate electricity at night you need a system that does the opposite of what solar panels do during the day. They are calling the new tehnology anti-solar or “heat engines.”

nighttime solar

New panels for nighttime generation of clean energy

Photovoltaic vs Thermoradiative Cells

These “heat engines” are made from a different kind of cell than a typical solar photovoltaic cell normally thought of when producing clean energy. The new cell is called a thermoradiative cell and works the opposite of the photovoltaic cell.

Jeremy Munday, professor in the Department of Electrical and Computer Engineering at UC Davis is currently busy developing nighttime solar cells that can generate up to 50 watts of power per meter with hopes of improving the power output with further research. Munday states, “Our device couples the cold side of the thermoelectric module to a sky-facing surface that radiates heat to the cold space and has its warm side heated by the surrounding air, enabling electricity generation at night.”

Nighttime solar

Anti-solar panels can generate nighttime energy.


In a recent paper published in the journal of ACS Photonics, Jeremy Munday explained, “A regular solar cell generates power by absorbing sunlight, which causes a voltage to appear across the device and for current to flow. In these new devices, light is instead emitted and the current and voltage go in the opposite direction, but you still generate power. You have to use different materials, but the physics is the same.”

With the ability to generate electricity around the clock, overcoming the lack of sunshine on cloudy days and long nights, we can move towards a sustainable planet, one more effort in combating our changing climate.

Droneseed: Fighting against Climate Change with Reforestation

dronesseed

drones and reforestation

“By using the newest technology of planting seeds by drones, Droneseed has increased the speed of reforestation.”

By Linn Smith

With climate change and the warming of our planet comes forest fires as evidenced by the recent fires in Australia. The wildfire season has gotten considerably longer and drought has fueled the fires. Rising temperatures evaporate more moisture from the ground and vegetation turns dry with lack of moisture. These events lead to a longer wildfire season. Acres and acres of forest and prairie act as tinder for any mistake by nature or man. Deforestation has many devastating results including erosion and furthering the effects of global warming by destroying a forest’s contribution to clean air, turning carbon dioxide into oxygen.

In the past reforestation depended on humans carrying seedlings, planting each nursery grown seedling by hand as they walked across the deforested areas. If reforestation does not take place in these areas, erosion washes away the top soil and unwanted invasive plants and ground cover may eventually take the place of native trees.

Droneseed

Droneseed is a relatively new company that is reseeding destroyed forests by dropping tree seeds by drones, mitigating the devastated areas. They are a Seattle-based group of people interested in using technology to help save our planet. They work with the Nature Conservatory and some of the largest lumber companies in the world. According to their website, http://www.droneseed.com, they are a team of “ nursery managers, foresters, ecologists, biologists, and engineers who love the data, theory, and the hands-on work necessary to grow forests.”

In an interview by Devin Coldeway (@Techcrunch), founder and CEO Grant Canary Canary stated, “I started looking into how it’s done today,” he told me. “It’s incredibly outdated. Even at the most sophisticated companies in the world, planters are superheroes that use bags and a shovel to plant trees. They’re being paid to move material over mountainous terrain and be a simple AI and determine where to plant trees where they will grow — microsites. We are now able to do both these functions with drones. This allows those same workers to address much larger areas faster without the caloric wear and tear.”

I have witnessed first hand the devastating changes from forest fires. With the beetle kill causing rapid flames to spread, the Hayman fire was Colorado’s largest, over 138,000 acres, rapidly spreading over the Colorado Rocky’s beautiful terrain. Riding past this area several years later revealed acres and acres of new ground cover with a few cabins that the forest service saved, standing alone amongst the baron, black terrain left by the fire.

Mitigation of Deforested Areas

Droneseed is on the forefront when it comes to mitigation of deforested areas. Using the newest technology of planting seeds by drones they have increased the speed of reforestation. According to Techcrunch.com, in the article, That Night a Forest Flew Droneseed, “Earlier this year, DroneSeed was awarded the first multi-craft, over-55-pounds unmanned aerial vehicle license ever issued by the FAA. Its custom UAV platforms, equipped with multispectral camera arrays, high-end lidar, six-gallon tanks of herbicide and proprietary seed dispersal mechanisms have been hired by several major forest management companies, with government entities eyeing the service as well.These drones scout a burned area, mapping it down to as high as centimeter accuracy, including objects and plant species, fumigate it efficiently and autonomously, identify where trees would grow best, then deploy painstakingly designed seed-nutrient packages to those locations. It’s cheaper than people, less wasteful and dangerous than helicopters and smart enough to scale to national forests currently at risk of permanent damage.”

drones

reforestation

Droneseed packages seeds to drop from their drones by studying the soil and matching the packages closely with the nutrients and soil PH of the area in need of reforestation. They dust the outside of the seed with capaicin, which creates the heat in hot peppers, to keep wildlife from eating the seed.

Droneseed expects to take its services worldwide, thus speeding the growth of deforested areas and pulling carbon dioxide out of our atmosphere and replacing it with oxygen. This process, in return, will slow down our planets warming climate, making our planet livable for future generations.

President Trump Withdraws The United States From The Paris Climate Agreement.

Sustainable living

It’s our responsibility to change.

“Most Americans Support the Paris Agreement.”

By Dr. John J. Hidore

Geological evidence indicates that the earth is now the warmest it has been in the last 650,000 years. Data also indicates the 20th Century was the warmest century in the past 1000 years. Most of the warmest years of record have occurred since the beginning of the year 2000. Climate change is now taking place faster and faster and is responsible for historic catastrophes around the world. It is clear to the majority of human beings inhabiting this planet that there is a serious problem of change taking place in our weather and climate.

The Paris Climate Conference-Cop21

In the fall of 2015 the historic Paris climate conference-cop21 (Conference Of Parties) was held. Out of that conference came what is generally know as the Paris agreement. The main goal of the group is to keep the mean temperature of Earth from increasing less than 2 degrees above the pre-industrial average temperature. It has already risen about half that. This means keeping the global temperature from rising no more than another 1 degree F. By reducing this much it would bring the level of carbon dioxide back to where it was at the beginning of the industrial revolution.

building green

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

An agreement was finalized on December 12, 2015. It was ultimately approved by nearly all nations. The group committed to keeping the global temperature rise to 1 degree F by the year 2100. A key difference in this agreement from previous agreements is that each individual country could set its own goals for reducing greenhouse gas emissions. The agreement imposes no penalties for countries which do not meet their own goals.

Prior conferences wanted to set the goals for each country. Some poor countries still wanted the richest countries to bear the biggest share of the cost or to make the biggest cuts in carbon emissions. The wealthier countries did commit $100 billion a year to help pay the costs for the poorest countries.

Climate Change 2016 Elections

Climate Change-Trump has NO plan!

Trump and the Paris Agreement

During the election campaign of 2016 and as President, Trump stated he would take America out of the Agreement. During the presidential campaign in 2016 he declared that climate change was a hoax. He also stated that if elected he would take the United States out of the 2015 Paris Accord.

On Thursday, June 1, 2017 the president of the United States announced that he was withdrawing the United States from the Paris Agreement. The reason he gave was that the agreement was unfair to this country and, as president, he has the right to do that. That this decision on his part has trashed America’s image abroad is an understatement. The United State has been leading the effort to take action to reduce or halt the human induced portion of climate change. However, on Monday, December 2, 2019 President Trump again announced that the United States would withdraw from the Paris Agreement. This left the other signatories of the agreement to plan action to combat climate change without participation of one of the major contributors to the problem.

Support of the Paris Agreement

Most Americans Support the Paris Agreement. Millions of individuals have now become activists on reducing climate change. People are changing their life styles to use less energy. They are publicly active to get local governments to cut energy use and to change to less carbon based sources of energy. The governments of a number of states have publicly declared they will continue to support the agreement. They will move ahead on measures to reduce greenhouse emissions and climate change.

California, which is the sixth largest economy on the planet, is pushing ahead to become a carbon free region. Other states are following suit even if they do not officially support the Paris agreement. The number of states has now reached about a dozen at the time of this writing. More will participate I am sure.

Clean Energy Plan

Support a Clean Planet for Future Generations!

Mayors’ Action on Climate

Groups of cities are actively working to reduce greenhouse emissions. More than 250 American cities officially adopted the Paris agreement. They are part of a group called Mayors National Climate Action Agenda. Among the cities that have agreed to support the Paris Agreement is Pittsburgh, Pennsylvania. This is the very city which Trump stated he represented although he did not represent the Paris Agreement. There is no doubt that the position the current president of the United States has taken is a shock to the rest of the world, let alone to the majority of the people in this country. However, the people of this country will not turn their backs on the rest of the world. They will stand with all nations that are committed to reducing the extent of climate change which, is even at this date, resulting in catastrophes.

Island nation populations are being forced to move or cease to exist. Inland rivers are undergoing record floods. Extreme high temperatures are doing tremendous damage to plants and animals.

How great the catastrophes are in the future depends on what our nation, along with nearly all others, does in regard to climate change. Let the United States lead the way!

Success of the Ocean Cleanup Project

“The latest announcement has plans for the collected ocean plastic from the Great Pacific Garbage Patch to prevent its return to the ocean.”

By Linn Smith

Boyan Slat is one of my environmental heroes! At the young age of 25, he is leaving his legacy in the world by sustainably creating a healthier planet. (Also see my previous article at https://planetearth5.com/2018/10/08/boyan-slat-and-the-ocean-clean-up-project/)

The Ocean Cleanup

The last several weeks Slat’s non-profit company, The Ocean Cleanup, has reached a milestone in cleaning up the Great Pacific Garbage Patch (GPGP) and cleaning up the rivers at the source of garbage dumping with the latest operation called The Interceptor, a floating operation that extracts garbage in rivers. As he stated, “We need to close the tap.” to the garbage entering the ocean.

A Message from Boyan Slat

Boyan’s message on December 12 was, “Mission one completed– The plans to make products from the plastic catch. Welcoming the first of the plastic on land is the moment we’ve been looking forward to. I believe we can use this trash to turn a problem into a solution by transforming this unique material into products. As most people will never go to the Great Pacific Garbage Patch, through these products we aim to give everyone the opportunity to take part in the cleanup.” After many months of trial and error and years of planning by Slat and his crew to get to this stage of the cleanup, success has been achieved!

Products from the Great Pacific Garbage Patch

The latest announcement are plans for the collected ocean plastic to prevent its return to the ocean. Sustainable products, launching in September 2020, will be made from the ocean plastic and sold to the public. Profits will be returned to the company to fund the continuation of the ocean cleanup.

Recycling: Creating Hope for a Greener Planet

Recycle

Recycle and Conserve

“European countries are recycling 35% to 40% [of their plastic waste]. The U.S. only recycles 10%.”

By Linn Smith

I am spending time in a suburb in the Southwestern part of the United States. After being a diligent recycler most of my adult life, I have come to realize that many households do not share my passion for doing their part to prevent further negative impact on our planet. Even though I’m conscientious about buying goods in bulk from local health food stores, I still accumulate some bottles, cans and plastics. It’s the world we live!

I have been in the Southwest for several weeks and have repeatedly asked people and businesses about a drop off place for glass and plastic. The answer is always the same….the surrounding suburbs no longer take drop off recyclables as rates have gone up and in some sections there has been complete halt on even curbside recycling for glass and plastic. Cans are less of a problem, as many are willing to turn them in for cash, but plastic and glass? My efforts have produced nothing.

Recycle

Recycling Shut Down!

Following is the message I found when trying to locate a place to drop off my recyclables:

**CLOSURE NOTICE**
All City of *****recyling Drop-off Centers Are Indefinitely Closed
Due to increasing recycling processing fees and decreasing commodity values, the City of **** has found it necessary to reevaluate its entire recycling program. While we value the importance and place high priority on conserving our natural resources, we must also take into account financial considerations to ensure we are able to maintain a sustainable program. The total operating cost for the City of ***** three recycling drop-off centers is approximately $250,000 per year. While we have been pleased to offer this service for many years and appreciate you visiting our centers, unfortunately the decision has been made to indefinitely close all three locations.”

Landfill

A newly formed mountain of waste.

The Landfill: A Mountain of Garbage!

I then sought out the local landfill. I couldn’t enter as the truck in the picture was on guard to keep out private citizens. But standing on the road running parallel to the landfill, I took in the site of a mountain newly produced by garbage from the city that won’t allow recycled dropoffs. As I stood in disgust of this newly formed mountain of garbage in our once beautiful desert Southwest, I wondered, “Where did we go wrong? Was it just a hundred years ago that people were growing their own food, canning, reusing their jars, sewing their own clothes, living what would now be called a sustainable life?”

Landfill

Guarding the landfill.

The site of all those recyclable materials sitting in a landfill in our beautiful desert for a hundred years and accumulating day by day, year by year is almost too much for me to comprehend. To me you either care about out planet, leaving future generations with at least the knowledge that you tried, or you don’t…..you further the “pig sty” concept of what use to be our beautiful earth. The choice is ours to not be lazy!

Where will our Recyclables Go?

The excuse for many cities is this….China quit taking our dirty waste which we had been shipping over to them since 1992 and that alone broke the recycling system in the U.S. Keefe Harrison, CEO of the Recycling Partnership, a nonprofit that seeks to boost the industry, stated “European countries are recycling 35% to 40% [of their plastic waste]. The U.S. only recycles 10%. How tragic is that? We’re fighting an uphill battle to make it cost competitive from day one. The U.S. has previously outsourced so much of its recycling to Asia that the domestic industry languished. And there’s the fact that plastic manufacturers keep making more and more of it, and consumer brands like Procter & Gamble, Nestlé and Walmart keep wrapping more consumer goods in it.”

According to an article in the Sierra magazine, China’s refusing to take our recyclables has given us the opportunity to develop a plan of our own if we care enough to go down that avenue. “The whole crisis narrative has been wrong,” says Steve Alexander, president of the Association of Plastic Recyclers. “China didn’t break recycling. It has given us the opportunity to begin investing in the infrastructure we need in order to do it better.”

Alliance to End Plastic Waste

There are many different types of plastic. Some can be recycled, some cannot. In the past companies have used the plastic most profitable without considering what happens to their product packaging.

Several petrochemical companies have joined big consumer brands in pledging to make most of their plastic recyclable, reusable or compostable within the next decade or two. Their group, Alliance to End Plastic Waste, has promised to spend $1.5 billion over five years to recycle their packaging products.

Every Bottle Back

Coke, Pepsi and Dr Pepper recently announced a plan, Every Bottle Back, to reduce their dependence on new plastic by collecting, recycling and remaking plastic bottles from plastic they have already produced. “Closed Loop Partners, the leading investment firm in sustainability, will manage upgrades to recycling infrastructure and fund upgrades to equipment at bottle recovery systems. The fund will also be used to help businesses that turn recycled bottles into plastic pellets for reuse in many products.”

The Ocean Clean Up

The Ocean Cleanup.

The Ocean Cleanup

Then there are the heroes of our planet.The Ocean Clean Up nonprofit organization, started by 25 year old Boyan Slat, is not only working on the clean up of the Great Pacific Garbage Patch, but has recently unveiled technology to clean up rivers that are streaming garbage to the ocean.
“The Interceptor is The Ocean Cleanup’s answer for river plastic waste. It is the first scalable solution to prevent plastic from entering the world’s oceans from rivers. It is 100% solar-powered, extracts plastic autonomously, and is capable of operating in the majority of the world’s most polluting rivers.”

The Interceptor

The Ocean Clean Up, Boyan Slat

But we cannot depend on a young man in his 20’s to clean up our planet, even though he has diligently done more than his part. We must all do our part also!

Climate Change: Marine Heat Waves

The Ocean Heat Wave

The Blob shows the warmest ocean .

“In recent years large regions of unusually warm water have been observed in the global oceans.”

By John J. Hidore

Terrestrial heat waves have been a problem for the human species throughout history. They occur on all continents with the possible exception of Antarctica. Technically, they occur there as well. Terrestrial heat waves are defined as prolonged periods of unusually warm weather. What would be defined as a heat wave in one location would not be appropriate for another location, perhaps one not even too far away. An adequate definition might be, “A heat wave is an unusually warm or hot period lasting for days or perhaps weeks.” We associate them with summer but by this definition they can actually occur at any season. At least one country makes a clear definition of a heat wave and that is Pakistan. India defines heat waves and uses different temperatures in different parts of the country to establish what constitutes a heat wave. In the plains regions temperatures above 40 degrees C (104 degrees F) constitute a heat wave. They also define a severe heatwave for this region as experiencing temperatures over 46 degrees C (114.8 degrees F).

The Ocean Heat Wave

Breaking previous ocean temperatures.

Marine heat waves

In recent years large regions of unusually warm water have been observed in the global oceans. These large areas of warmer than usual water develop when surface winds drop in velocity or become calm and are now referred to as marine heat waves. These large areas of unusually warm water(MHWs) are defined in similar terms to heat waves on land as prolonged periods of unusually warm water. In the United States NOAA defines a marine heat wave as an event where the surface water temperature is warmer than 90% of past events whose temperatures were warmer than average for that particular time of year and location for at least five days. The term” blob” has been applied to them. The term was the name given to an event that occurred off the west coast of the United States in 2014-2015.

Pacific Ocean Heat Wave of 2019

A marine heat wave developed over a large part of the northeastern Pacific Ocean this past summer. It extended from Hawaii to the Pacific coast of the United States and stretched all the way from Alaska to California. Temperatures off the coast here rose by 2-3 degrees Fahrenheit. Off the west coast of the United States the blob resulted in a large loss of marine life from microorganisms to large fish. It subsequently affected marine animals and birds. The Hawaiian Islands had the warmest summer on record this year. The effects of the current MHW had a major impact on life in the ocean near the islands. The warmer water resulting in extensive coral bleaching damage to the reefs.

These events are a product of the 21st century, occur in the oceans around the world and are occurring more often and are lasting longer.

Eco Wave Power is a company founded in 2011 which is the only company in the world that turns ocean waves into clean energy, connecting wave floaters to the power grid. Since 2016 the Wave Farm has been providing Gibraltar, a tiny country bordering Spain, with electricity. Eco Wave Power is also a 2019 recipient of the United Nation’s Climate Action Award.

Clean and Affordable Energy

According to the U.N. Climate Action organization,”The project generates clean and affordable electricity, using a simple design that allows the project’s uniquely shaped floaters to be attached to existing man-made structures (such as piers, breakwaters and jetties), and thereby simplifying the installation process, as well as maintenance and accessibility.”

How Wave Energy Works

The converter consists of three main functional parts: mechanical, hydraulic and electric systems. The mechanical system serves as a wave energy receiver on floaters and transmits the energy to hydraulic cylinders. The hydraulic system transforms the mechanical energy from the sea to hydraulic fluid pressure and forces a hydraulic motor rotation, which transfers the energy from rotation to the generator. The generator is part of a converter electrical system. It receives the energy from rotation and transforms it to electrical power.

Key Facts according to U.N. Climate Action

*Wave energy has historically been uncommercialized due to the complexity of extracting energy from the ocean. This project has successfully developed and commercialized wave energy, resulting in a grid-connected array that has operated continuously since 2016.

*In 2018, the station set a world record for wave energy when it clocked over 15,000 grid-connection hours.

*Commercializing wave energy has enormous potential — the World Energy Council predicts that wave energy can produce twice the amount of electricity the world currently produces.

*More than half the world’s population lives within 100 km (62 miles) of a coastline, and in many locations, the power of the waves is available around the clock.

Being easy to build and cost efficient these floaters also have little negative impact on the environment. Gibraltar has been a test site and Eco Wave’s plan for further expansion are on the horizon!
