Environmental effects of sustainable energies (Case Study: Solar, Wind and Hydroelectric Energy)

Increasing air pollution and global warming due to the excessive use of fossil fuels attracted public attention to climate change. Accordingly, the expected increase in demand for other alternative energy sources especialy renewable energy is predictable. While some research on renewable energy shows that these kind of energy also have undesirable environmental effects. In this study solar energy systems, wind power and hydroelectric power systems wew investigated and their effects on air, soil, sound and effect on wildlife were studied. The results show that although these kind of energy are called clean energy, they have negative environmental effects. This research also suggests ways to prevent the effects of destructive renewable energy sources.
