New climate review guidelines take big-picture look at renewables

With the need to reduce use of fossil fuels in transportation and other areas, demand is likely to increase for solutions that increase dependence on electricity and the electrical grid.  

Renewable energy sources — once the fuel of the future, then practical in specific, narrow applications — are increasingly economic mainstream sources of power generation. Hydropower was long the mainstay of U.S. renewable electricity generation, although wind power surpassed hydro for the first time in 2019, and solar continues its rapid growth. The continued growth of wind and solar, with their fluctuations, is tied in part to improvements in storage technology: batteries.
