There are more benefits from renewable energy sources, both economically and ecologically. Using bio mass reduces the harmful gas emissions known as the greenhouse effect, which is due to fossil fuels, it means less pollution.   Bio mass is readily available for use wherever it is, so it reduces costs of exploitation, as well as reduces dependence on imports. Also, the use of solar energy and wind energy is much cheaper and easily accessible. But the general benefit of renewable sources is energy sustainability, because fossil fuel sources are reduced without the possibility of renewal.
