Some gas plant developers and their backers are talk ing up the prospect of burning hydrogen in the plants as a way to address carbon pollution and keep the plants from becoming irrelevant as we make the necessary transition to a low-carbon economy. And how would that approach compare to using renewable energy?

If we are to protect the ocean, its marine ecosystems and the people who depend on them, we must address climate change at its root: the burning of fossil fuels for energy. But this cannot happen without clean-energy solutions, such as offshore wind and other marine renewables , that can replace them.

Their study examined the carbon dioxide and methane emissions from these companies’ products, as well as from the extraction and production processes of the largest gas, oil and coal producers and cement manufacturers. Data on the major carbon producers’ emissions have been published since 2014.

Solar panels generated almost 4 percent of electricity in the US in 2021, up from less than 1 percent in 2015. In some places that number is much higher; for example, 17% of California’s electricity generation came from solar in 2021. Almost half of all new energy capacity added to the US grid in 2021 came from solar.

This would have enabled the CAISO to expand its operations into the rest of the west as a regional transmission organization (RTO), an independent entity that plans and operates the electricity grid. Now, 22 states plus the District of Columbia and Puerto Rico have 100% clean energy goals on the books.
