Here are some ways you can save energy. The light bulbs that I have at home are 60 watts and the light bulbs [CFL] that we got in the kit were 13 watts. By replacing the old light bulbs with the new ones, we are saving 47 watts per day, or 17.2 kWh per year. By replacing an old light with a new light [Limelight], we are saving 40 watts per day, or 14.6 kWh per year. One way to save energy is to only take 5 minute showers. Also my family is saving energy by when you brush your teeth only put on the water when you need it. Also a Nonrenewable Resource means it can't come back once we use it so instead of using coal we can use algae and that is more energy efficent. Here are some ways but there a lot more ways to save energy.
