The majority 6–3 decision sharply curtails the EPA’s authority to set standards based on a broad range of flexible options to cut carbon emissions from the power sector—options such as replacing polluting fossil fuels with cheap and widely available wind and solar power coupled with battery storage.

In turn, this means a given percentage of hydrogen (by volume) blended in doesnt lead to the same percentage reduction in the amount of gasor to the same reduction of carbon emissions. A blend with 50% hydrogen by volume, for example, gets you only 23% less smokestack carbon pollution.

Fossil gas, or “natural gas,” as it’s been cunningly branded, is a fossil fuel that causes warming and is harmful to human health. Its mainstream name is nothing more than a clever marketing scheme by Big Oil to make the fuel sound natural, safe, and clean. This is a huge problem. Many reasons!

However, several analyses—including a recent one by the Union of Concerned Scientists (UCS)—have concluded that the IRA, even when coupled with the bipartisan infrastructure act and other federal and state climate policies, will not be enough to meet US carbon emission reduction goals. Energy efficiency also plays a critical role.

All told, they represent 56 percent of the US population, generate 62 percent of the country’s gross domestic product, and are responsible for 43 percent of the country’s annual carbon emissions. Emissions of sulfur dioxide and nitrogen oxides from power plants in alliance states drop 88 percent and 77 percent respectively by 2040.

Communities and ecosystems continue to suffer the consequences of human-caused climate change , primarily from the burning of fossil fuels across our economy. The case for phasing out of fossil fuels and making a just and equitable transition to clean energy has never been more clear. comes from burning fossil fuels.
