Your ENERGY choices matter

COSI’s new Energy Explorers exhibition focuses on how energy powers the world around us-from the transportation we take, to the products we buy, to the ways we live and work. You'll learn where energy comes from, how energy powers the world, and why the energy choices you make are choices that matter.


Your energy use impacts your personal comfort and finances, friends and family, the environment, your wallet, and your planet. In the Energy Explorers Game, choose your "Energy Explorer," and make choices throughout the exhibit that challenge you to become an energy hero.

What happens during a BLACK OUT?

You may not have thought about where energy comes from, but you'll find out here. It's Electrifying: Shock yourself and your friends with an electric current. Restore the Power: There's a blackout in the neighborhood. Can you redistribute power and get the lights turned back on? May the Best Bulb Win: Use a hand crank to power incandescent, CFL, and LED light bulbs.

What can YOU do at home

Energy Vampires: Find the energy vampires in your house and eliminate them. Don't Run Out of Gas: Try to make it to the gas station behind the wheel of this driving game.
