Hydropower: Switch Energy Project
Hydropower can be an always-on, baseload power, or spin up almost instantly to follow rising electricity demand—with no fuel to burn and no emissions. Building the power plants is high impact and expensive, but they produce cheap electricity for many decades. Hydropower is so good, we’ve used up almost all the locations for it. The few large-scale projects in the future will be in China, India, Africa, and other developing areas.
