Energy Storage 101

Energy from renewable sources, such as solar and wind power, are variable by nature: The winds may not blow; the sun may not shine; but utility customers still need to turn their lights on.

For this reason, energy storage is often referred to as “the missing piece” of the renewable energy puzzle. Innovators are constantly seeking new ways to make energy storage cheaper and more efficient. Stay up to date on the latest headlines!
