What kind of renewable energy is the worst for the environment?

    I would say those forms of renewable energy based on combustion. We are not able to burn anything without some form of effluent at this point. So biofuels, like cellulosic ethanol, which is made from plants. It burns cleaner than fossil fuels, but when combusted it still emits pollutants. Advocates, however, contend that they only return to the atmosphere the CO2 they used to grow.
