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.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

In comparison, the energy density for lithium-ion batteries used in commercial electronics and electric vehicles is around 170–250 Wh/kg. Our primary goal for this technology is to enable low-cost, daily shifting of solar energy into the electrical grid over a 10- to 24-hour period. —Weller et al. Weller et al.
