Situated next to power plants and wind and solar farms, battery energy storage systems (BESSs) are rechargeable battery systems, most commonly using lithium ion, that provide steady sources of power. By storing energy already generated, they stabilize gas and coal power and support solar and wind. If energy were money, BESS would be like having an overdraft account to back up your checking account.

From water to solar and coal to wind, the sources of energy that build and power our world have appropriately faced ethical, moral, scientific, and political scrutiny.
