    Top 10 Renewable Energies

    Some guys list. But he is misinformed about nuclear power. Nuclear fission rather than fusion and even fission relies on materials that are not renewable. Also, natural gas isn't revewable either.

    10 Tidal Power - Tidal energy can be generated in two ways, tidal stream generators or by barrage generation.
    9 Wave Power - Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work — for example for electricity generation, water desalination, or the pumping of water (into reservoirs).
    8 Solar Power - Photovoltaic (PV) Solar power is harnessing the suns energy to produce electricity.
    7 Wind Power - Wind power is the conversion of wind energy by wind turbines into a useful form, such as electricity or mechanical energy.
    6 Hydroelectricity - Hydroelectricity is electricity generated by hydropower, i.e., the production of power through use of the gravitational force of falling or flowing water.
    5 Radiant Energy - This natural energy can perform the same wonders as ordinary electricity at less than 1% of the cost.
    4 Geothermal Power - Geothermal energy is a very powerful and efficient way to extract a renewable energy from the earth through natural processes.
    3 Biomass - Biomass, as a renewable energy source, refers to living and recently dead biological material that can be used as fuel or for industrial production. In this context, biomass refers to plant matter grown to generate electricity or produce for example trash such as dead trees and branches, yard clippings and wood chips biofuel, and it also includes plant or animal matter used for production of fibers, chemicals or heat.
    2 Compressed Natural Gas - Compressed Natural Gas (CNG) is a fossil fuel substitute for gasoline, diesel, or propane fuel.
    1 Nuclear Power - Nuclear power is any nuclear technology designed to extract usable energy from atomic nuclei via controlled nuclear reaction
