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 23 2013: I like the idea of geothermal energy because it releases far less carbon dioxide then burning fossil fuels and very little nitrous oxide and sulfur gas are given off. It can be constantly produced and can cut energy bills by 30-40%. The biggest down fall and ultimate demise of this type of energy is how much it costs to put geothermal energy plants in place. Of the figures I saw it costs roughly 1-4 million to drill well and in-home geothermal energy pump system are roughly $30,000. This is really expensive and our infrastructure here in the U.S. I don't believe has a good amount of access to drilling sites. Not to mention what kind of side effects drilling may have on biodiversity.
