Hydropower Does More Than You Think: Six Things To Know About This Renewable Energy Powerhouse
Pumped storage hydropower already accounts for 93% of utility-scale energy storage, and it''s growing at a fast—and necessary—rate. Over the past decade, pumped storage capacity in the United States grew by almost as much as all other types of energy storage combined, mostly due to upgrades at existing plants.
Reports Show Hydropower''s Value Will Likely Grow in Transition to Clean Energy
They found that hydropower could both support and accelerate the country''s transition by helping to reduce energy costs and providing critical energy storage. In the first white paper, for example, the team estimates that PSH''s 6- to 10-hour storage could have significantly more value over time as compared to shorter-duration energy …
