It’s not just the poor air quality, long lines, and excessive fossil fuel company representation ; nations are still too far apart in their positions on a fossil fuel phaseout, the top priority for this COP. Yet global fossil fuel production and use continue to expand. Particulate matter (PM2.5)

With the clean energy transition already under way, the US electricity mix is set to continue changing this year. Solar power is expected to make up about half of all additions of US electric generating capacity in 2023, according to data from the US Energy Information Administration (EIA). I’ll start off with the good.

Union of Concerned Scientists’ (UCS) research shows that top fossil fuel producers’ emissions are responsible for as much as half of global surface temperature increase. The best solution: Replace fossil fuels with renewable energy. Pitting climate and energy against each other is an insidious lie.

The shift from fossil fuels in the 100% RES scenario reduces the amount of harmful air pollution from power plants much more than in our “No New Policy”/business-as-usual scenario. Just as important, cleaning up the power grid can also decrease carbon dioxide (CO 2 ) emissions. And our modeling shows renewables’ power.

We need more electricity to transition our homes and cars off fossil fuels, but we can’t afford to let that electricity come from more gas power plants. Aging plants and state clean energy goals are certainly helping that trend. But we’ve also reached the point where the economics of renewables are just much better.

But with the recent influx of government incentives for hydrogen production, new and improving production and storage technologies, and greater political will than ever before, H 2 ’s reputation is gaining favor. All this is not to say there is no place for hydrogen in a clean energy future.

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. The West Virginia v.
