Explanation
Each energy source carries a characteristic environmental drawback.
Wind energy is hazardous for birds and bats that collide with the turbine blades.
Thermal energy from burning fuel causes emissions of greenhouse gases.
Hydroelectric energy floods valleys and leads to loss of riparian vegetation along riverbanks.
Photovoltaic energy involves production of toxic wastes during the manufacture and disposal of solar cells.
Weighing these impacts guides the cleaner planning of energy systems.
