Hydroelectric Stations

Generating electricity using clean, free, renewable energy might sound like a scientific marvel somewhere in the distant future. But in reality it's been around for more than 100 years. Hydroelectric power plants generate electricity by capturing the energy from water as it flows downhill in rivers toward the sea.

It's pollution-free because nothing is burned. And once the hydroelectric plant is built, the power is free (except for maintenance and operating costs) because gravity and water are provided courtesy of Mother Nature. Best of all, since rains replenish the river water, energy used in hydroelectric power generation is 100 percent renewable.
