This Challenge is for everyone to help fight climate change by reducing energy usage. Our collective actions have a direct impact on the demand for energy. If you are already taking some actions, challenge yourself and see if you can do more. Sign up now. Form a team within your Go Green group and choose from 54 actions to take during the Challenge. Let’s see which team can take the most actions from Earth Day (April 22) until May 13. Our Earth can use all the help it can get.
