Batteries can also be used to assist with peak electricity demand; currently instead of batteries, fossil fuel-powered “peaker plants” are often used to supply energy during high-demand periods. Despite being used infrequently, these plants are inefficient and highly polluting, and contribute to US carbon emissions.

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. From 2020 to 2040, solar generation in these states jumps nearly ninefold and wind generation more than sevenfold.

CO 2 emissions remain mostly level through 2050—nowhere close to meeting US climate goals. Carbon emissions remain high. Wind capacity steadily increases, mostly due to policy (the federal tax credit, which expires in 2024, and state RPS policies).

Glen Canyon Dam is now operating at about 60 percent of its designed hydroelectric capacity, according to Nick Williams, the Upper Colorado River Basin power office manager for the Bureau of Reclamation. Rated for 1,320 megawatts — roughly the size of a large fossil fuel plant — the dam is now capable of only 800 megawatts.

Japan, a long-time supporter of nuclear power, now has serious hydrogen ambitions. The 2020 Tokyo Olympics will be powered by hydrogen. Hydrogen may have lost the race to fuel electric cars but it looks a likely contender to replace fossil fuels in trucks, ships, planes and heavy industry. By Fred Pearce.

Once completed, it is intended to supply power, on a priority basis, to the industries being set up at the Gwadar Free Zone (GFZ), a special economic zone at Gwadar port that forms part of the China-Pakistan Economic Corridor (CPEC), the USD 62 billion bilateral infrastructure and connectivity project between China and Pakistan.

A recent National Renewable Energy Laboratory (NREL) study shows that it would take less than 1 percent of the land in the Lower 48—that’s an area comparable to or even smaller than the fossil fuel industry’s current footprint.
