Tidal Energy - Ocean Energy Council

What is tidal energy? Tidal energy is one of the oldest forms of energy used by humans. Indeed, tide mills, in use on the Spanish, French and British coasts, date back to 787 A.D.. Tide mills consisted of a storage pond, filled by the incoming (flood) tide through a sluice and emptied during the outgoing (ebb) tide through a water wheel. The tides turned waterwheels, producing mechanical power ...

World Energy Needs and Nuclear Power | Energy Needs ...

The world will need significantly increased energy supply in the future, especially cleanly-generated electricity. Electricity demand is increasing about twice as fast as overall energy use and is likely to rise by more than half to 2040. Nuclear power provides about 10% of the world's electricity, and 18% of electricity in OECD countries.

Why Nuclear Power Must Be Part of the Energy ... - Yale E360

In the early 1950s, when the U.S. Atomic Energy Commission believed high-grade uranium ores to be in short supply domestically, it considered extracting uranium for nuclear weapons from the abundant U.S. supply of fly ash from coal burning. In 2007, China began exploring such extraction, drawing on a pile of some 5.3 million metric tons of brown-coal fly ash at Xiaolongtang in …

How Do Wind Turbines Work? | Department of Energy

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
