The main polluting renewable energy source is biomass. This can be burnt as a replacement for fossil fuels in power stations. It can also be left to decompose which produces biogas. This is rich in methane and is suitable as an alternative to natural gas.

This is due to the fact that most forms of renewable energy are not as powerful as nonrenewable energy. Also if all gas stations were to turn into electric stations for electric cars, what would happen to all the cars that are run by Gas? The swap or change would be hard to make. Although using renewable energy is much better for the environment the change would be very difficult to make.____
