What form of renewable energy has or will have the lowest impact on biodiversity?

Climate change, air pollution, rising sea levels and species extinction can all be attributed to the increasing usage of non-renewable energy in the world today. Non-renewable energy reserves are diminishing and finite with an ever-increasing demand from countries around the world. Coal, natural gas and oil all have detrimental effects on the environment. These effects are both local and global, harming species throughout the world. As we consider different renewable forms of energy, can we rank their potential impacts on biodiversity?

    Apr 24 2013: I think this is a issue that many people focus on and try to find some alternative energy, especially clean energy. When thinking about the energy with lowest impact on biodiversity, I think is solar power and wind power. Firstly, they are clean. Compared with oil and coal, the solar and wind do not produce carbon dioxide and gas pollutants. Secondly, they are kind of infinite. From Rob's talk, we know that oil cannot support us for a long time. And water is also deficient, but solar and wind are easy to get.
    However, when I studied conservation biology, I knew that wind power blades can cause the birds death. So it also influences biodiversity, but compared with other forms of energy, it is a little.
    Here are links related to solar energy and wind energy
