Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21 st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. They find that large-scale wind power generation would warm the Continental United States 0.24 degrees Celsius.

What is energy storage?

Setec Powerr

At its core, energy storage unlocks energy flexibility, allowing it to play a critical role in balancing electricity supply and demand, making the electrical grid more reliable and cleaner. While lithium-ion batteries can discharge for a long time, a sweet spot is around two to four hours, based on the economics.

BloombergNEF: clean energy investment in developing nations slumps as financing in China slows; coal burn surges to record high

Green Car Congress

New investment in wind, solar, and other clean energy projects in developing nations dropped sharply in 2018, largely due to a slowdown in China. The findings suggest that developing nations are moving toward cleaner power but not nearly fast enough to limit global CO 2 emissions. thousand terawatt-hours in 2018, up from 6.4
