Solar Parking Lots In France | Earth Wise

By Leave a Comment

France has passed legislation that will require all parking lots with more than 80 spaces to be covered over by solar panels.  This is part of a broader effort to put solar panels on vacant lots, empty land alongside roadways and train tracks, and even some farmland.  The overall program would add 11 gigawatts of solar power to the French electricity grid.

The legislation applies to both new and existing parking lots.  Owners of parking lots with more than 400 spaces would have 3 years to comply, while owners of lots with 80 to 400 spaces would have five years.

To produce 11 gigawatts of solar output, about half a percent of France’s urban land would need to be covered with solar panels.  This is quite a bit, but not an insurmountable obstacle.  Parking lots, however, could only provide a fraction of what is needed.  It would take something like 8 million parking spaces covered with solar panels to produce that much power.  That is probably at least twice as many as France has.

Several countries, most notably Germany, already have mandates for new construction to incorporate renewable energy.  This includes solar panels, biomass boilers, heat pumps, and wind turbines.  Many parking lots in southern Europe already have sunshades over them, which would make it pretty easy to install solar panels.  This is much rarer in cooler countries.

France is pursuing this policy to reduce its dependence on nuclear power, which currently provides 70% of the country’s electricity.  Apart from the general trend of opposition to nuclear power, reliance upon it during increasingly common droughts is problematic as the power plants require significant amounts of water to operate.

Banning Gas-Powered Cars | Earth Wise

By Leave a Comment

In June, the European Union voted to ban the sale of new gas- and diesel-powered vehicles starting in 2035.   The EU joined Canada, the United Kingdom, Japan, South Korea, and several other countries in imposing future gas car bans.

Here in the U.S., on August 25th, California adopted rules banning the sales of new gas-powered cars and light trucks by 2035.  New York passed a similar law last year and its ban will also cover heavy trucks by 2045.

California’s action is particularly significant because there are other states that have trigger laws that impose their own bans based on what California does.  Washington state, Massachusetts, and Virginia are in this category, although the governor of Virginia has said he plans to try to repeal the law.

An additional 12 states have policies tied to California’s and are likely to adopt their own versions of the 2035 ban.  These are Colorado, Connecticut, Delaware, Maine, Maryland, New Jersey, New Mexico, Nevada, Oregon, Pennsylvania, Rhode Island, and Vermont.

When these regulatory actions are coupled with the major investments in electric vehicles being made by virtually all automakers, the transition to electric vehicles appears to be inevitable.

As far as people who love their gas-powered cars are concerned, the new rules only apply to new car sales.  So, consumers can still buy and own used cars that run on gasoline.  If there are states that never impose bans on new gas-powered vehicles, then consumers can go to those states and buy one, assuming there are any being made at that point.   It seems likely that gas-powered cars will end up being made for hobbyists and aficionados only.

The Importance Of Wildlife Crossings | Earth Wise

By Leave a Comment

Highway accidents involving animals are a big problem for both people and animals.  According to the National Highway Traffic Safety Administration, motorists in the United States kill one to two million large animals every year.  About 200 people are killed annually in the U.S. as a result of those collisions with animals.   

These crashes are expensive, too.  Deer-vehicle collisions cost an average of more than $8,000 each; elk-vehicle collisions cost about $25,000; and moose-vehicle collisions cost more than $44,000.

One solution that has been quite effective around the world in reducing car-animal collisions is wildlife overpasses and underpasses.  They are designed to help animals move in search of food and to escape predators and wildfires.  These traffic-spanning bridges and tunnels have been popular in Europe since the 1950s.  They look much like regular overpasses for cars but are decked out with native flora.  The underpasses, which assist shyer and smaller animals, are typically invisible to drivers.

According to a new economic analysis by researchers at Washington State University, wildlife crossings in Washington State save roughly $235,000 to $443,000 every year per structure. 

Wildlife crossing structures range in cost from $500,000 for a tunnel-like underpass to more than $6 million for a broad bridge.  There may soon be many more wildlife crossing structures across the country since $350 million was allotted in the federal Infrastructure Investment and Jobs Act signed into law in 2021.

A Law To Tackle Climate Change | Earth Wise

By Leave a Comment

The Inflation Reduction Act signed into law in mid-August is the most comprehensive U.S. legislation addressing climate change ever enacted.   It contains $369 billion in funding for clean energy and electric vehicle tax breaks, domestic manufacturing of batteries and solar panels, and pollution reduction.

The legislation for the most part makes use of carrots rather than sticks to coax American consumers and industry away from reliance on fossil fuels.  Rather than establishing more carbon taxes, mandates, and penalties, the law largely makes use of tax credits to provide incentives for the use of clean energy.

The law provides a large mix of tax breaks intended to bring down the costs of solar, wind, batteries, electric cars, heat pumps, and other clean technology.  For example, consumers will get a $7,500 credit for purchasing many new electric car models and about $4,000 for buying a used vehicle.

On the stick side of the ledger, oil and gas companies that emit methane above certain threshold levels will incur fees that escalate over time.  The law also increases the cost to the oil industry for extracting fossil fuels from public lands.

The act provides $60 billion for overall environmental justice priorities, including $15 billion targeted specifically for low-income and disadvantaged communities. There are many other provisions in the law addressing multiple climate-related issues.

According to three separate analyses by economic modelers, the investments from the Inflation Reduction Act are likely to cut pollution by about 40% below 2005 levels by the year 2030.

A Geoengineering Research Plan | Earth Wise

By Leave a Comment

The 2022 federal appropriations act, signed into law in March, directed the Office of Science and Technology Policy to develop a cross-agency group to coordinate research on climate interventions, in partnership with NASA, the National Oceanic and Atmospheric Administration, and the Department of Energy.

The group is tasked with creating a research framework to “provide guidance on transparency, engagement, and risk management for publicly funded work on solar geoengineering research.”  The group is supposed to develop a five-year plan that will define research goals for the field, assess the potential hazards of climate interventions, and evaluate the level of federal funding required to carry out the work.

This marks the first federally coordinated effort of this kind and is especially significant because it contributes to the perception that geoengineering is an appropriate and important area of research as the climate continues to warm.

It is an understatement to say that such research is controversial.  Geoengineering has often been a taboo topic among scientists. There are significant questions about potential environmental side effects and concerns that the impact of any such efforts would be felt unevenly in different parts of the world.  There are challenging questions about global governance , including who should be able to make decisions about any potential deployment of climate interventions and what the goals of such interventions should be.

These are momentous issues to grapple with, but as the threat of climate change grows and nations continue to fail to make rapid progress on emissions, researchers, universities, and nations are increasingly motivated to seriously explore the potential effects of geoengineering approaches.  We can’t hide from the fact that these issues are going to be explored.

Upgrading The U.S. Power Grid | Earth Wise

By Leave a Comment

The Department of Energy has launched the Building a Better Grid Initiative to accelerate the development of new power transmission lines.  The initiative aims to upgrade the nation’s grid, connect more Americans to clean electricity, and reliably move clean electricity to where it is needed most. The initiative is a part of the Bipartisan Infrastructure bill that was signed into law in November.

Under the initiative, DOE will identify critical national transmission needs and support the buildout of long-distance, high-voltage transmission facilities as well as support transmission planning, financing mechanisms, transmission-related research and development, and efforts on energy justice.

DOE will deploy more than $20 billion in federal financing that includes more than $10 billion in grants to states, Tribes, and utilities to enhance grid resilience and prevent power outages.  It will also coordinate with other agencies to streamline permitting for transmission infrastructure. 

Seventy percent of the US grid’s transmission lines and power transformers are over 25 years old.  There is also insufficient transmission capacity, especially for transmission that facilitates transfer of power across regions.  The current grid is vulnerable to harsh weather and needs improved reliability.

Providing more transmission capacity in areas where it doesn’t exist today is essential for the integration of more large-scale renewable generation sources into the grid.  The national goal of 100% clean electricity by 2035 is not just about decarbonizing the generation sources.  A substantial upgrade to the transmission infrastructure is necessary and the Building a Better Grid Initiative is a major step in the right direction.

Last New York Coal Plant Closing | Earth Wise

By Leave a Comment

The last coal-fired power plant in New York State is closing.  The plant, located in Barker, about an hour’s drive from Buffalo, employs 44 people.  The plant’s closure is an early test of New York’s new climate law, which is one of the most ambitious in the country.  The law is supposed to transform the state’s energy grid to carbon-free by 2040. 

Coal plants across the country are going offline, priced out by natural gas and targeted by regulations and incentives aimed at reducing greenhouse gas emissions.  Coal plant closures bring common challenges:  lost tax revenues and jobs as well as efforts to retrain workers and clean up sites.  Every plant has a specific place in a community, and each community has its own story.

The new climate law is supposed to create thousands of new jobs, including high-paying union jobs like the ones the employees in Barker are losing.  But jobs are scarce in the northwest corner of the state where Barker is located.

The state government has recently issued rules that would make it easier to get permission to build renewable energy sites, including wind turbines and solar farms, allowing applicants to bypass zoning rules and other local regulations.  But residents of rural towns have environmental and aesthetic concerns about these potential new energy plants.

In 2010, the United States had 580 coal-fired power plants providing 45% of the country’s electricity. By March 2018, there were fewer than 350 plants and coal’s market share had dropped to 30%.  At this point, there are about 224 plants producing 18% of the country’s power.  The writing is on the wall for coal power.

Excluding Climate Change From Infrastructure Planning | Earth Wise

By Leave a Comment

According to a new Trump administration proposal, federal agencies would no longer need to take climate change into account when evaluating infrastructure projects.  The proposed changes to the 50-year-old National Environmental Policy Act (NEPA) are aimed at speeding up approvals for highway construction, pipelines, oil and gas leases, and other major infrastructure projects.   

Under NEPA, federal agencies are required to consider how their proposed actions would affect everything from water quality to wildlife to greenhouse gas emissions.  They’re also required to understand how rising seas and other consequences of climate change might affect a given project.  These requirements have proven to be an obstacle to projects like the Keystone XL pipeline, for example. 

According to reporting in the New York Times, the administration also plans to narrow the range of projects that require environmental review in the first place.  That could make it more likely for projects to be approved without having to disclose plans to do things like cut down trees, discharge waste, or increase air pollution. 

The administration says that the changes would improve the environmental review and permitting process while ensuring a safe, healthy, and productive environment. Environmentalists say the proposed changes would weaken critical safeguards for air, water, and wildlife. 

The proposed changes to NEPA would revise the rules that guide the implementation of the law, as opposed to amending the act itself.  Once these proposed changes appear in the federal register, the public will have 60 days to comment on them. 

A decision on whether or not to weaken the nation’s benchmark environmental law is expected before November.

Roofs Going Green

By Leave a Comment

Green roofs are roofs on buildings that are partially or completely covered with vegetation and a growing medium, generally planted over a waterproofing membrane.  The modern version of these roofs began in Germany in the 1960s and spread to many other European countries over time.  With concerns about climate change and shrinking natural resources rising, green roofs are becoming increasingly popular across North America.  The Toronto-based organization Green Roofs for Healthy Cities estimates that the number in North America has increased by about 15% since 2013.

Replacing black asphalt and shingles with plants can lower the surrounding air temperature, filter dirty storm water, and reduce building energy use.  The National Research Council of Canada estimates that a green roof can reduce air conditioning use in a building by as much as 75%.  The roofs also help to reduce air pollution and greenhouse gas emissions according to the EPA.

As the benefits of green roofs become more widely known, cities around the world are passing green roof legislation.  Copenhagen passed a law in 2010 requiring all new commercial buildings to have green roofs if their roofs are not sloped too much.  Toronto was the first city in North America to pass a green roof law in 2009.  Over 640 green roofs covering more than five million square feet have since been constructed in Toronto.

Apart from the environmental benefits, green roofs are providing pleasant spaces in the urban environment that may include flower beds, trees, herb gardens, gazebos and picnic tables.  As for the economics, studies show that over the course of a roof’s lifetime, green roofs are actually considerably cheaper than conventional roofs taking into account energy savings.

Labeling Genetically Engineered Foods

By Leave a Comment

There has been a great deal of debate over mandating labels for genetically engineered foods.  On the pro side, people argue that they have a right to know whether what they are eating contains GMO – or as they are also called GE — ingredients.  On the con side, people argue that the aversion toward GE is unfounded and that labeling foods will simply drive away consumers undeservedly.
