Energy conservation is one of the best things we can do for the Earth . This is what I have learned from it. I learned that you can take showers without spending a lot of time inside of them. Also you can use CFL lightbulbs instead of regular ones. And instead of using regular nightlights try to use efficient ones instead called a Limelight. When it is winter you can turn your heater up 2-3 more degrees higher than what you did in summer. My family has been more efficient now than we have been.
