Progress towards electric school buses

November 8, 2024 By EarthWise Leave a Comment

The U.S. has nearly half a million school buses providing daily transportation for about 20 million students. Most of these buses are powered by diesel engines which not only dump greenhouse gases into the atmosphere but also fill kids’ lungs with harmful fumes.

Thanks to various federal and state incentive programs, this situation is starting to change. School districts all over the country are beginning to swap out old diesel buses for emissions-free electric-powered school buses.

Electric school buses are finding their way into school districts of all sizes and demographics. The first district in the country to go fully electric was in Martinsville, Texas, which last year converted its 4-bus fleet. The first large urban district to go all-electric was the 74-bus fleet in Oakland, California this summer.

The EPA’s $5 billion Clean School Bus program and many state initiatives are providing incentives for the transition. Five years ago, there were less than 1,000 electric school buses in the U.S. Now there are about 5,000 and more than 7,000 additional buses are in the pipeline.

Apart from the climate implications, there is urgency to replacing diesel school buses from a health perspective. Diesel exhaust is classified as a carcinogen by the World Health Organization, and it contains fine particles and nitrogen oxides, both of which are well-documented asthma triggers.

Electric buses are more expensive than diesel buses, but they are much cheaper to operate. School districts need to put in place charging infrastructure. The transition is not so easy to accomplish, but it is an important step, and more and more school districts are taking it.

Electric cars: Boom or bust?

September 25, 2024 By EarthWise Leave a Comment

Media coverage of electric cars in this country is pretty confusing. Are electric cars taking over or has the EV bubble burst?

EVs currently represent about 8% of the US new car market. But they continue to face some relatively unique headwinds in this country. A very powerful and influential oil industry makes sure that anti-EV stories occupy center stage in the media. Traditional car dealers don’t want to sell EVs because they don’t make much money from parts and service. And EVs often find themselves tangled up in American politics.

Meanwhile, the rest of the world tells a very different story. Globally, EVs constitute 20% of new car sales, but in some places, they are doing much better than that.

So far this year, almost 87% of new car sales in Norway are electric and in August, the figure was 94%. Norway has some incentives in place for EV owners, but the fact that nearly all new cars on the road are electric is far more than the result of incentives.

One might argue that Norway, a country with only 5 million people, faces a much easier task of transitioning to EVs. But how about China with its 1.4 billion people? In July, plug-in vehicles in China were 51% of new auto sales. And the numbers continue to rise.

There are plenty of articles out there explaining why electric cars just can’t meet people’s needs, have insurmountable problems, and how having too many of them would collapse electric grids and otherwise wreak havoc with society. Apparently, the Norwegians and Chinese, among a growing number of other countries, haven’t gotten the memo.

Electric Cars And Apartments | Earth Wise

July 10, 2023 By EarthWise Leave a Comment

The transition to electric cars is underway. People are increasingly buying them, carmakers are switching over to making them, and governments are providing incentives as well as legislating the changeover. More and more consumers want to lower their carbon footprints and stop burning fossil fuels. But one very large group of consumers faces an uphill battle in switching to electric cars: people who rent their dwellings.

About one third of our country lives in rented apartments or houses. These nearly 110 million Americans are more likely to be in the bottom half of income and net worth and are more likely to be people of color. These people are less likely to have the spare cash to make upgrades to their property such as car chargers and may not be able to get permission from their landlords to do it anyway.

Renters face what is known as the “split-incentive problem” or the “landlord-tenant problem.” Three-quarters of tenants in the US pay their own utility bills, so they have a strong incentive to conserve electricity, water, and gas. Their landlords, on the other hand, have little incentive to upgrade appliances and systems to be more environmentally responsible. Studies have shown that on average renters use 3% more energy than homeowners for this reason.

There are some landlords who are being proactive and installing facilities for charging cars on their properties. This will undoubtedly become an increasingly sought-after feature for renters. But in the meantime, millions of them have a more difficult time driving electric cars. They can charge at public chargers or perhaps at work. But at the moment, homeowners are three times more likely than renters to own an electric car.

New York Bans Some Crypto Mining | Earth Wise

December 13, 2022 By EarthWise Leave a Comment

Crypto mining, the arcane process by which cryptocurrencies are generated, is incredibly energy-intensive. As of this past summer, global electricity usage for the activity is as much as 240 billion kilowatt-hours per year, which is more than many entire countries use (for example Australia and Argentina.) Crypto mining consumes as much electricity as all the conventional computer data centers in the world.

All that energy usage is problematic for the environment, but a growing practice has made it far worse. Crypto miners have been re-powering decommissioned fossil fuel power plants to produce electricity strictly for mining operations. Doing so eliminates the climate benefits achieved by shutting down those plants.

The New York State Legislature passed a bill in June that would place a two-year moratorium on permits to re-power fossil fuel plants. It does not prevent crypto mining from existing generation sources. The bill had sat on the governor’s desk until after the recent election. But in late November, Governor Hochul signed the bill despite considerable lobbying against it.

The temporary ban was heavily opposed by cryptocurrency industry groups, to no surprise. While some states actually offer tax incentives to lure crypto mining operations, supporters of the legislation hope that New York’s action may cause others to follow its lead and stop the reactivation of old fossil fuel plants.

The two-year moratorium will allow time to properly evaluate the impact of the crypto mining industry on the state’s climate goals. It is pretty obvious that reactivating old, retired fossil fuel power plants as an energy source is a move in the wrong direction.

Schools And Solar Power

June 19, 2019 By EarthWise Leave a Comment

A new study from Stanford University looked at the benefits of installing solar panels on the rooftops of schools. According to the study, taking advantage of all the viable space for solar panels could allow schools to meet up to 75% of their electricity needs and reduce the education sector’s carbon footprint by as much as 28%.

Given the long list of spending priorities for schools, solar power seems like a luxury item. But the Department of Energy estimates that K-12 schools spend more than $6 billion a year on energy and, in many districts, energy costs are second only to salaries. In the higher education sector, yearly energy costs add up to more than $14 billion. In total, educational institutions account for approximately 11% of energy consumption by U.S. buildings and 4% of the nation’s carbon emissions.

The Stanford study suggests that investments in the right solar projects combined with the right incentives from states could free up much-needed money in school budgets.

To no surprise, the study finds that three large, sunny states – Texas, California, and Florida – have the greatest potential for generating electricity from solar panels on school rooftops.

Apart from measurable effects on air pollution and electricity bills, solar installations at schools can also provide new learning opportunities for students. In fact, some schools are already using data from their on-site solar energy systems to teach students basic ideas about fractions, as an example, as well as more sophisticated concepts such how shifting solar panel angles can affect power production.

According to the study, nearly all states could reap value from school solar projects.

A Million Electric Cars

September 25, 2018 By EarthWise Leave a Comment

Last year, China was the first country to reach the milestone of having one million electric cars. This year, China will add another million plug-in vehicles. Of course, with its huge population, China sells four times as many cars in total per year as any other country.

Lots Of Credit For Carbon Capture

March 23, 2018 By EarthWise Leave a Comment

These days, the federal government has mostly turned its back on efforts to mitigate climate change or, for that matter, to even recognize its existence. However,the budget bill passed in February contained a major increase in the tax credit known as 45Q, which provides incentives to businesses to develop and utilize carbon capture, utilization and storage technologies.

Storing Energy With Captured CO2

May 17, 2017 By EarthWise

Capturing carbon dioxide instead of releasing it into the atmosphere is a way we can use fossil fuels without it having harmful effects on the climate. Energy storage is a way to address the volatility of clean energy sources like wind and solar power. Excess energy stored during peak production can be used when production ceases, such as when the sun is not shining or the wind is not blowing.

Utility-Scale Solar Power

May 11, 2017 By EarthWise

Solar panels on the roofs of houses have become a familiar sight in recent years, but utility-scale solar – installations of 10 megawatts and greater – are really booming these days. Throughout the United States, more than 10.5 gigawatts of utility-scale solar were added to the electric grid in 2016 – enough to power more than 2 million homes – and at least 8 gigawatts more are scheduled to come online this year.

Solar Power In China

March 27, 2017 By EarthWise

Installations of solar power continue to increase rapidly around the world and in no place more than China. By the end of 2016, total solar generating capacity in China reached 77.4 gigawatts, making it the largest producer of solar energy in the world. Globally, there is a total of 228 gigawatts of solar power installed, although that number keeps changing rapidly.

European Lessons On Food Waste

February 17, 2017 By EarthWise

Americans toss out an almost unbelievable $161 billion worth of food every year. There are numerous efforts underway to address this problem, but they are mostly at the local level or in the business sector. To date, we have no national- or international-level policies that tackle the issue. In this regard, Europe is way ahead of us.

Small Forests And Climate

October 26, 2016 By WAMC WEB

Trees are the number one way in which carbon can be removed from the atmosphere and stored in vegetation over the long term. A single tree can absorb CO2 at a rate of 48 pounds per year. Because of this, the carbon footprints of 18 average Americans can be neutralized by one acre of hardwood trees. And it has been found that managed forests accumulate more carbon per acre than unmanaged forests.
