The end of the Chevron deference

August 6, 2024 By EarthWise Leave a Comment

At the end of June, the US Supreme Court upended 40 years of legal precedent in a ruling that sharply limited the regulatory authority of federal agencies. The so-called Chevron Deference doctrine stated that when a legislative delegation to an administrative agency on a particular issue or question was not explicit but rather implicit, a court may not substitute its own interpretation of the statue for a reasonable interpretation made by the administrative agency.

Under the new ruling, courts will have more power to interpret these statutes. Environmentalists fear that this decision could lead to hundreds of rules being weakened or even eliminated, particularly Environmental Protection Agency limits on air and water pollution, regulations on toxic chemicals, and policies to tackle climate change.

Conservative political organizations have been pushing for decades to roll back the government’s regulatory powers. The new ruling creates a massive opportunity for environmental regulations to be challenged, considering the proliferation of increasingly activist, right-leaning courts. In particular, climate regulations under the Clean Air Act are more susceptible to judicial reversal. The ruling shifts the power from the agencies to the courts.

The danger of this decision is that more Americans will suffer from the worse effects of climate change, air pollution, and other environmental harms that current government regulation protect against. Any time that the Court makes it harder for the government to regulate and easier for businesses to challenge regulations, it makes it more likely that industries will injure the public and the planet in search of profits. This is basic economics in action.

Big Oil And Big Lithium | Earth Wise

July 7, 2023 By EarthWise Leave a Comment

The world’s big oil companies have worked pretty hard to prolong society’s dependence on petroleum. When there are trillions of dollars at stake, there is plenty of motivation. But those companies do see the writing on the wall.

An Exxon Mobil-funded study last year estimated that light-duty vehicle demand for combustion engine fuels could peak in 2025 and that electric vehicles of various types could grow to more than 50% of new car sales by 2050. This is pretty pessimistic compared with most other surveys, but it is still a big number. Exxon also projected that the global fleet of EVs could reach 420 million by 2040.

As a result of all this, Exxon is preparing for a future far less dependent on gasoline by drilling for lithium rather than oil. The company recently purchased mining rights to a sizable chunk of Arkansas land for over $100 million from which it aims to produce lithium for electric car batteries.

Exxon’s consultants estimated that the 120,000 acres in the Smackover formation of southern Arkansas could have as much as 4 million tons of lithium carbonate, enough to power 50 million cars and trucks.

Exxon plans to spend $17 billion through 2027 on cutting carbon emissions and developing low carbon technologies. Other large oil producers have also been looking at the lithium business. At the same time, some large oil companies like BP and Shell are investing in renewable energy.

The prospect of EVs dominating transportation in the coming decades is a strong incentive for oil-and-gas companies to adapt their businesses to the new world.

Distributed Wind Energy | Earth Wise

March 17, 2023 By EarthWise 1 Comment

When we think about wind power, we are usually talking about increasingly giant windfarms – either on land or offshore – that produce power on a utility scale. But there is also distributed wind energy, which refers to wind technologies in locations that directly support individuals, communities, and businesses.

Distributed wind can be so-called behind-the-meter applications that directly offset retail electricity usage much as rooftop solar installations do. It can also be front-of-the-meter applications where the wind turbines are connected to the electricity distribution system and supplies energy on a community scale. Distributed wind installations can range from a several-hundred-watt little turbine that powers telecommunications equipment to a 10-megawatt community-scale energy facility. As of 2020, there were nearly 90,000 distributed wind turbines in the U.S. with a total capacity of about 1 GW.

A study by the National Renewable Energy Laboratory has estimated the potential for distributed wind energy in the U.S. According to the new analysis, the country has the ability to profitably provide nearly 1,400 GW of distributed wind energy capacity.

Entire regions of the country have abundant potential. The regions with the best economic prospects have a combination of high-quality wind, relatively high electricity rates, and good siting availability. Overall, the Midwest and Heartland regions had the highest potential especially within agricultural land.

Realizing this outcome for distributed wind will require improved financing and performance to lower costs, relaxation of siting requirement to open up more land for wind development, and continued investment tax credits and the use of net metering.

Keeping Trash Out Of The Ocean | Earth Wise

February 23, 2023 By EarthWise Leave a Comment

The Ocean Cleanup is a non-profit organization, founded in 2013 by Dutch inventor Boyan Slat, to develop and scale technologies to rid the world’s oceans of plastic. It is an organization that proudly declares that its primary aim is to put itself out of business by successfully cleaning up the oceans.

A major activity of The Ocean Cleanup is efforts to clean the ocean garbage patches that have accumulated in several places, best-known of which is the Great Pacific Garbage Patch. The effort involves use of large U-shaped floating barriers that act as an artificial coastline to trap garbage which is then funneled into a barge for disposal. Ten full-sized systems will be needed to clean up the Great Pacific Garbage Patch.

A second activity of The Ocean Cleanup is preventing garbage in rivers from making its way into the oceans. Rivers are the main source of ocean plastic pollution. The Ocean Cleanup has developed river machines called Interceptors that capture garbage for disposal. Last fall, they installed a machine called Interceptor 007 in Ballona Creek, a waterway in the Los Angeles area. In the first rainfall after installation, the Interceptor managed to stop 35,000 pounds of waste from entering the ocean in just a few days.

The original Interceptor models have been deployed in Indonesia, Malaysia, the Dominican Republic, and Vietnam. A different type called the Interceptor Trashfence is being tested in Guatemala.

The Ocean Cleanup states that if fleets of its barrier systems are installed in all the garbage patches and Interceptors in the 1000 most significant rivers, 90% of floating ocean plastic can be removed by 2040.

Bitcoin Mining And The Environment | Earth Wise

November 7, 2022 By EarthWise Leave a Comment

Bitcoin mining, the process by which the prominent cryptocurrency is created, is well-known to be energy intensive, but the environmental impact of it has not been extensively studied. People have described Bitcoin as ‘digital gold.’ A new analysis by researchers at the University of New Mexico has found that Bitcoin mining shouldn’t be compared to gold mining. It is more appropriately compared to the creation of much more energy-intensive products such as beef, natural gas, and crude oil.

Furthermore, the study found that rather than becoming more sustainable over time, Bitcoin mining is becoming dirtier and more damaging to the climate as long as it relies upon fossil-fuel generated electricity. Estimates are that in 2020, Bitcoin mining used 75.4 terawatt hours of electricity, which is more electricity than the entire country of Austria, as well as 150 other nations around the world.

The study looked at the economic cost of the air pollution and carbon emissions associated with Bitcoin mining and found that in many instances, the negative economic impact of creating a single Bitcoin is more than what the resultant coin is worth.

Based on the market value of Bitcoins, the cost of climate damage for that value is a little less that that of electricity produced by natural gas and gasoline produced from crude oil, but actually more than that of beef production.

There are multiple cryptocurrencies. Ether is one that voluntarily switched away from so-called proof-of-work mining. Whether Bitcoin or others will act similarly absent potential regulation remains to be seen. Until such time, Bitcoin mining remains an increasingly dirty and damaging business.

Electric Cars And The Remote Road Test | Earth Wise

August 18, 2022 By EarthWise Leave a Comment

One reason many people are hesitant about switching to an electric car is range anxiety, the fear that their car’s battery will die on them in the middle of a trip. It is pretty much the same thing as running out of gas, but somehow it seems like more of a danger.

Perhaps this was true when charging stations were few and far between and electric cars couldn’t go very far on a charge, but these days, the average electric car can drive about 200 miles on a charge and there are charging stations all over the place.

A big difference between gas cars and electric cars is that many people can charge their cars at home and start every day with the equivalent of a full tank. With an electric car, there is little reason to use up all nearly all the charge before filling up the tank again.

The truth is that most people don’t drive all that much on the average day anyway. In the US, the average driver goes about 39 miles a day. In Europe, is it considerably less. Yes, there are some people who drive 200 miles a day, but they are few and far between.

Remote and regional Australia is a place where distances between essential services can be very large. But a new study from the Australian National University found that even under those trying conditions, the vast majority of residents, about 93%, can go about their business even with the lower-range electric vehicles available on the market without having to recharge en route.

Electric cars may not be practical for some drivers, but for most, they are already a great choice.

30 Million Solar Homes | Earth Wise

March 29, 2021 By EarthWise Leave a Comment

A national coalition made up of more than 230 organizations has launched an initiative called the 30 Million Solar Homes campaign. The goal is to add enough rooftop and community solar energy to power 30 million homes across the U.S. over the next five years. That would be the equivalent of one in four American households.

The major focus of the 30 Million Solar Homes initiative is to rapidly and massively scale programs that help low-income families benefit from solar power. The coalition lists 15 federal policy initiatives including making solar tax incentives more equitable, providing more reliable low-income energy assistance through solar energy, supplementing low-income weatherization assistance with solar energy, and specifically funding solar projects in marginalized communities.

The federal government spends billions of dollars every year to help families to pay their energy costs, but these efforts only serve less than a fifth of the eligible population. Funding rooftop and community solar access for these households would provide long-term financial relief and reduce the need for annual energy bill assistance.

The more than 230 organizations in the coalition represent organizations focused on energy equity, climate, business, environment, faith, and public health. The coalition estimates that executing the plan would create three million good-paying jobs, lower energy bills by at least $20 billion a year, and reduce total annual greenhouse gas emissions by 1.5%.

Over the coming months, the campaign will seek to educate lawmakers and the Biden-Harris Administration about the benefits of distributed solar energy. The vision outlined by the coalition is an ambitious one to say the least.

Paying To Combat Climate Change | Earth Wise

November 2, 2020 By EarthWise Leave a Comment

The majority of Americans believe that climate change is happening, that human activities are largely responsible, and are actually willing to put up their own money to help fight it. Unfortunately, these views diverge sharply along party lines and, as in many other areas these days, the will of the overall majority has little influence on policy.

According to Yale University research, 73% of adults think that global warming in happening and 57% think it is mostly caused by human activities. Furthermore, only 32% believe it is due to natural forces.

A survey conducted in the U.S. in August found that more than two-thirds of Americans – actually 70% – indicated willingness to donate a percentage of their personal income to support the fight against climate change.

Breaking that down further, 28% were willing to provide less than 1% of their income, 33% were willing to contribute 1-5% of their income, 6% said they would give 6-10% of their income, and 3% said they would contribute more than 10% of their income. On the other hand, roughly 30% indicated that they were unwilling to contribute.

The survey also looked at opinions on how the fight against climate change should be paid for. The majority (59%) chose government incentives for both businesses and consumers. Three other options each favored by over 40% of those surveyed were taxes, conservation programs, and business investments.

Another finding of the survey was that 44% are dissatisfied with the job that the federal and state governments are doing to address climate change, 35% are somewhat satisfied, and only 21% are very or completely satisfied with the government’s role.

Saving Costs And Reducing Emissions From Shipping | Earth Wise

March 2, 2020 By EarthWise Leave a Comment

International shipping is a large and growing source of greenhouse gas emissions. Maritime transport produces about a billion tons of CO2 annually, accounting for about 2.5% of global greenhouse gas emissions. The environmental impact of shipping includes air pollution, water pollution, and even acoustic pollution. In many coastal areas, ships are responsible for more than 18% of some air pollutants. Overall, there are more than 100,000 transport ships at sea, of which about 6,000 are large container ships.

In recent years, the shipping sector has had both internal willingness and external pressure to reduce emissions, but shipping is a tough, competitive business and it isn’t easy to stay competitive and help protect the environment.

A recent study at Abo Akademi University in Finland has found that improved ship utilization rates and investments in environmentally sustainable technologies for enhanced energy efficiency would significantly reduce carbon dioxide emissions. Of equal importance, those same measures would contribute to lowering of freight costs.

If the same cargo volume can be shipped using less fuel, shipping companies will gain major savings in terms of fuel costs. Digitalization can provide valuable benefits. For example, new digital planning and booking systems would enable smarter use of routes while also diminishing traffic with half-empty vessels or even ones with no cargo aboard. Reducing such underutilization would improve the capacity utilization rate and eliminate emissions caused by so-called ballast traffic.

Global shipping continues to grow. It is essential that it becomes smarter and more efficient to protect the environment and improve its economics.

SUVs And Carbon Emissions

December 17, 2019 By EarthWise Leave a Comment

Global carbon dioxide emissions increased between 2010 and 2018. The largest contributor to this increase was the power sector as electricity demand around the world continued to grow. The second largest contributor to increased emission turns out to be SUVs, even while emissions for other cars actually decreased.

During that time period, SUVs more than doubled their global market share from 17% to 39% and their annual emissions rose to more than 700 million tons of CO₂, which is more than the yearly total emission of the UK and the Netherlands combined.

This dramatic shift toward bigger, heavier SUVs has offset both efficiency improvements in small cars and savings from electric vehicles. If SUV drivers were a nation, they would rank 7^th in the world for carbon emissions.

SUVs are bigger, they are heavier, and their aerodynamics are poor. As a result, it takes more gas to drive them. They started to become popular in the 1980s – mostly in American suburbia – but now they have become globally popular.

The demand for SUVs is thought to be driven by perceptions of heightened safety or increased social status. There is also the marketing and business strategy of manufacturers who obtain larger profit margins in the SUV segment. Of course, for at least some consumers, the utility aspects of sport utility vehicles are actually important and not just the status.

For whatever reasons, SUVs are likely to be extremely popular for the foreseeable future as demand for sedans continues to decline. Fortunately, electric SUVs are beginning to enter the market – including next year’s mass-market priced Tesla Model Y. Such cars are the best solution to emissions from SUVs.

Safe And Simple Hydrogen Peroxide

November 29, 2019 By EarthWise Leave a Comment

We don’t think about hydrogen peroxide very often. Perhaps we have a bottle of it under our bathroom sink that we haven’t touched in a few years. But it is an important product manufactured in the millions of tons each year and the basis of a $6 billion global business.

Hydrogen peroxide is widely used as an antiseptic, a detergent, in cosmetics, as a bleaching agent, in water purification, and in many other applications. It is produced in industrial concentrations of up to 60% in solution with water in order to maximize the economics of transportation. This makes transportation hazardous and costly because the concentrated form is unstable. Most applications use a far more diluted form.

Researchers at Rice University have developed a new method for producing hydrogen peroxide that is much simpler and safer than the current technology, which actually dates back to the 1930s. The Rice technique requires only air, water and electricity to produce the chemical. The electrosynthesis process, which is detailed in the journal Science, uses an oxidized carbon nanoparticle-based catalyst.

The process could enable point-of-use production of pure hydrogen peroxide solutions, which would eliminate the need to transport the hazardous concentrated chemical. The use of a solid electrolyte instead of the traditional liquid electrolyte eliminates the need for product separation or purification that is part of the current technology.

In the future, instead of storing containers of hydrogen peroxide, hospitals that use it as a disinfectant could turn on a spigot and get, for example a 3% solution on demand. Instead of storing chemicals to disinfect swimming pool water, future homeowners could flick a switch and turn on their peroxide reactor to clean their pools.

Solar Equity for Low-Income Communities

May 30, 2019 By EarthWise Leave a Comment

A couple of years ago, the number of American roofs covered with solar panels passed the one million mark and the numbers keep growing. But nearly half of U.S. households – accounting for more than 154 million people – aren’t able to host their own solar arrays because they lack suitable rooftop space, or they rent their homes. But millions more simply can’t afford to spend tens of thousands of dollars to buy or lease solar panels.

In recent years, community solar has become popular. These are projects where multiple participants own or lease shares in a mid-sized solar facility and receive credits that lower their monthly utility bills. Community solar in the U.S. has more than quadrupled just since 2016.

However, the majority of community solar subscribers to date have been businesses, universities, government agencies, and higher-earning households. These users can generally pay steep project enrollment fees or meet various financial requirements. Meanwhile, those who could benefit most from access to renewable energy and lower utility bills – low-income residents – have largely been left out.

Low-income households on average spend over 8% of their income on utility bills, about three times more than moderate- to high-income households. So, reducing electricity bills with community solar power is a big deal for them.

Given this situation, there are now a growing number of programs that make use of community solar to reduce living expenses for low-income households. In a dozen states, new programs include a variety of mandates, financial incentives, and pilot programs targeting benefits for people with low incomes. These programs will allow them to participate in both the environmental and economic benefits of renewable energy.

Australian Plastic Bag Ban

December 31, 2018 By EarthWise Leave a Comment

Last summer, the two largest supermarket chains in Australia – Coles and Woolworth’s – decided to stop offering single-use disposable plastic bags to customers. The initial public reaction was decidedly negative. However, within just three months after the radical change, the country’s National Retail Association reported an 80% drop in the consumption of plastic bags nationwide.

In that three-month period, it is estimated that 1.5 billion bags have been prevented from use. Some retailers are reporting reduction rates as high as 90% in the use of the bags. The move by the big supermarkets has paved the way for smaller businesses to follow suit. The smaller businesses typically can’t afford to risk the wrath of their customers with a major change like this. Customers have to learn to bring their own bags or buy reusable bags at the store.

In much of Australia, the phase-out of plastic bags has been legislated, but the state of New South Wales, home to Sydney, the country’s largest city, has not enacted such legislation. So, supermarkets themselves are doing the work of getting rid of the bags.

The change has not been without hiccups. For the first couple of months after the plastic bag ban was put in place, Woolworth’s saw poor sales in its stores. However, customers eventually got used to the new way of doing things and sales levels returned.

Disposable plastic bags often find their way into the oceans where they break down into microparticles. Studies have shown that these plastic bits are ingested by a wide variety of marine life. For example, a UK study found that 100% of sea turtles in the Pacific and Atlantic oceans as well as the Mediterranean Sea had plastic in their digestive systems.
