A Law To Tackle Climate Change | Earth Wise

September 8, 2022 By EarthWise 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.

Continued Renewables Growth | Earth Wise

June 17, 2022 By EarthWise Leave a Comment

In 2021, the world added a record amount of 295 gigawatts of renewable power. According to the International Energy Agency, it is on pace to surpass that amount in 2022.

Almost half of the renewable buildout in the world is taking place in China. In 2021, China accounted for 46% of worldwide renewable energy additions. The EU and United States are the next two leaders. The rapid buildup is especially impressive given the challenges developers have faced from the coronavirus pandemic, supply chain issues, and various construction delays.

Predictions are that the global total added this year will be about 320 gigawatts of renewables. This amount is equivalent to the total power demands of Germany, which is the world’s fourth-largest economy. Solar photovoltaics are forecast to account for 60% of the increase in global renewable capacity this year.

The rapid growth in China and the EU are driven by strong pro-renewable policies. In our country, wrangling over climate legislation and investigations into potential trade violations by Asian suppliers have held back our progress. But over the next several years, offshore wind will begin to have a real impact on U.S. renewable installations.

According to the report by the International Energy Agency, renewable energy growth is likely to plateau in 2023 unless stronger climate policies are enacted.

There are now more than 3 terawatts – that’s 3,000 gigawatts – of renewable generation capacity globally. This compares with a little over 4,000 terawatts of fossil fuel generation. Global renewable energy generation is currently projected to surpass that of fossil fuels by 2035.

Five States Stepping Up On Clean Energy | Earth Wise

February 7, 2022 By EarthWise Leave a Comment

While Congress continues to face partisan gridlock on climate issues, many states have moved forward with climate action.

In 2021, five states – Illinois, Massachusetts, Oregon, North Carolina, and Rhode Island – passed laws requiring a shift to 100% carbon-free electricity or net-zero emissions. Washington State passed a law that helps to implement its strong 2019 and 2020 climate and clean energy laws. Washington’s new legislation establishes a carbon trading program that will help the state to meet its goals of economy-wide emission cuts and 100% carbon-free electricity.

Several other states made progress on climate and clean energy by taking targeted actions not quite as aggressive as 100% laws, but significant, nonetheless.

The five states that entered the so-called 100% club joined with the six states that had earlier passed such legislation. Those are California, Hawaii, New Mexico, New York, Virginia, and Washington. Both Puerto Rico and Washington D.C. are also members of the club.

The past year may well be the biggest year yet for significant clean energy legislation. Some of the states that finally passed laws had been gearing up for it for years. This is particularly true of Massachusetts and Illinois.

Actions by individual states are not an antidote to inaction by the federal government, but they help. At this point, about one-third of the country’s population lives in states that have laws requiring a transition to 100% carbon-free electricity, 100% renewable electricity, or net-zero emissions.

All of this activity began in 2015, when Hawaii passed its renewable energy law.

Perennials To Attract Pollinators | Earth Wise

November 26, 2021 By EarthWise Leave a Comment

There has been a decline in the abundance of insect and other animal pollinators in many ecosystems worldwide that began being observed at the end of the 20th century. Pollinators and their health have become growing concerns for the public and many states have enacted legislation related to pollinator decline.

In many places, the pollinator decline has largely been driven by a loss of flowering plants in the landscape, the primary source of food for the pollinators. A new study by Penn State researchers looked at the attractiveness to pollinators of various species of perennial flowering plants that people can plant in their gardens and other landscapes.

It turns out that there is considerable variation in how attractive different flowering plants are to pollinators. Greenspaces such as parks and gardens have the potential to support very rich pollinator communities, even including rare or vulnerable species.

People generally select ornamental plants because of their appearance and growth habit, not because of their pollinator attraction.

The Penn State study looked at a variety of perennials and identified the most attractive plant cultivars, which can attract 4 times the number of pollinator species than the least attractive plants studied.

The most appealing plant is the ‘Blue Fortune’ giant hyssop. Other highly attractive plants are the anise hyssop, the ‘Black Adder’ Agastache, the Cat’s Meow and Walker’s Low Nepetas, and the Triloba and Herbstonne Rudbeckias.

Many of these plants produce large floral displays and the researchers suggest that they should be prioritized when planting a pollinator garden amongst other species with comparably small floral displays and lower attractiveness to pollinators.

COVID-19 And The Wildlife Trade | Earth Wise

December 17, 2020 By EarthWise Leave a Comment

Historically, many diseases have jumped from animals to people with serious consequences for the human host. In fact, coronaviruses alone have caused outbreaks in humans three times in the past 20 years: SARS, MERS, and COVID-19. The majority of human pathogens that caused substantial damage to human health and economies during the past three decades have originated from wildlife or livestock.

According to a team of researchers from the University of Göttingen and other international institutions, more epidemics from animal hosts are inevitable unless urgent action is taken. In order to help protect against future pandemics, which could be even more severe than the current one, the researchers published a series of suggestions for governments to consider in the journal Trends in Ecology & Evolution.

The research team calls for governments around the world to establish effective legislation to do three things: address the wildlife trade, protect habitats, and reduce the interaction between people, wildlife, and livestock.

The wildlife trade and habitat fragmentation both facilitate disease outbreaks by increasing the potential for contact between humans and animals. Animals in wildlife markets are often kept in crowded and unsanitary conditions, which creates fertile breeding grounds for pathogens to jump to humans. Animals and humans are also forced closer together when natural habitats are cleared or otherwise fragmented in order to meet the various needs of a growing global population.

Since the Covid-19 outbreak, China, Vietnam, and South Korea have introduced regulations to better manage the wildlife trade as well as support wildlife conservation. According to the researchers, these actions serve as examples for other countries to consider. The status quo isn’t good enough.

Roofs Going Green

November 21, 2019 By EarthWise 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.

New York Offshore Wind

September 18, 2019 By EarthWise Leave a Comment

New York has passed ambitious legislation to reduce the carbon emissions that cause climate change, but the state needs to start taking action to make those reductions possible. One such action it has taken is an agreement that will enable the construction of two large offshore wind projects.

The projects are to be built off the coast of Long Island. One will be 14 miles south of Jones Beach and the other 30 miles north of Montauk. The wind farms will be built by a division of Equinor, a major Danish energy company, and a joint venture between Orsted, another Danish company, and Eversource Energy, an American firm.

The two New York wind farms are expected to be operational within the next five years and have the capacity to produce 1,700 megawatts of electricity. That is about 20% of Governor Andrew Cuomo’s overall goal for offshore wind.

Wind farms are a major energy source in the United States, now providing about 7% of the country’s electricity. That compares with only 2% in 2010. But nearly all American wind turbines are on land. There is only one small offshore wind farm in the US off the coast of Rhode Island. Things are very different in Europe. For example, Britain expects to get 10% of its electricity from offshore wind next year, which is up from less than 1% in 2010.

Developers of offshore wind farms have struggled to gain a foothold in the US. Some projects have foundered because of cost issues, but others have faced opposition from politicians and coastal-property owners. But assuming the New York wind projects clear permitting and environmental hurdles, offshore wind may finally be on the move in the US.

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.
