THE POWER OF WATER.

Hydroelectric power is becoming an increasingly important replacement for fossil fuels, meeting around 15% of the world's electricity needs and supplying about a billion people with power. Major hydroelectric schemes are currently under construction, particularly in China. Hydroelectric power plants convert the potential energy of water collected in a dam into electricity through turbines and generators. These plants are cheap to run, produce zero waste, and do not generate pollution. Impressive hydroelectric power plants include the Itaipu Dam in Brazil and Paraguay, the Guri Dam in Venezuela, and the Three Gorges Dam in China. However, not all countries have the infrastructure to take advantage of hydroelectric power. The UK, for example, relies on small-scale hydro projects and pumped-storage schemes. Other alternative sources of renewable energy include wind farms, solar power, biomass energy, geothermal energy, and wave power. [Extracted from the article]
