Solar power

Solar power is a good alternate source of energy. it is also, renewable. But it is very expensive and only when it is sunny you get energy at night it does not work. Building it causes pollution but once it is built it does not cause pollution.

Hydro Power

Using Hydro Power is a safe alternative for lighting and heating our homes and businesses. Harnessing water for power is a lot less harmful than using coal and gasses. Hydro power should replace all environmentally harmful sources of electricity and power and we should sell our harmful resources to Europe and the U.S so they have to suffer the pollution and not Canada.
