Environmental impact of electricity generation
![](https://commons.wikimedia.org/wiki/Special:FilePath/Kraftwerk_Ekibastus.jpg?width=300)
The environmental impact of electricity generation is significant because modern society uses large amounts of electrical power. This power is normally generated at power plants that convert some other kind of energy into electrical power. Each system has advantages and disadvantages, but many of them pose environmental concerns.
