                  Renewable energy can be replaced all the time. It does not pollute the
                  environment in the same way that fossil fuels do, but it is difficult to store and
                  often needs the right weather.

                  Renewable energy is not as efficient as non-renewable sources and we need
                  more of it to make enough energy, but it is the energy resource of the future!
