Introduction

Renewable energy is energy obtained from resources that are replenished rapidly by natural processes (Kalogirou, 2013). These natural processes wind, sunshine, tides and waves, rain, geothermal power, and biological processes.

Environmental Impacts of Renewable Energy Sources

All energy sources including renewable energy sources have an effect on the environment. Wind turbines change air pressure and cause death of birds and bats from the collision with the turbines. Hazardous materials like hydrochloric and sulfuric acid are used in manufacturing and cleaning of photovoltaic cells used in solar panels. Open-loop geothermal power systems emit and release hydrogen sulfide, carbon dioxide, and methane into the atmosphere. Hydrogen sulfide ...
