Both of the boats we just looked at use forms of renewable energy. Renewable energy comes from an energy source which will never be depleted. Fuels like oil and gas which we use everyday will eventually run out, where renewable energy sources are always there. In many places there is always wind, and rivers will always have currents because of the way they flow. Right now large amounts of our energy come from nonrenewable sources which will eventually run out, as our use of energy increases. Nonrenewable sources of energy also have harsh, lasting effects on the environment, from pollution to contributing to the greenhouse effect. Although they are more reliable than renewable sources of energy it is important that we begin to find other ways of harnessing energy. (What is renewable energy)
