Question

Can renewable energy sources be pollution free.List any two reasons for your answer

Answer 1

All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. ... Renewable energy often relies on the weather for its source of power. Hydro generators need rain to fill dams to supply flowing water.
