In looking for alternative energy sources to meet future needs, some common physical phenomena are obvious candidates. One of these is tidal power. Twice each day on every coastline in the world, bodies of water are pulled onto and off of the shore...

Tides occur as a result of interaction between the earth and the moon. Construction of dams permits harnessing of energy due to periodic water level differences for production of electric power. This means of energy production, while theoretically...

Tidal power, sometimes called tidal energy, is a form of hydropower that exploits the movement of water caused by tidal currents or the rise and fall in sea levels due to the tides. Although not yet widely used, tidal power has potential for future...

Tidal power Elements of Tidal-Electric Engineering. By Robert H. Clark. Wiley-IEEE Press, John Wiley & Sons, Inc., 111 River St., Hoboken, N.J. 07030-5774; (201) 748-6011. $130 (hardbound). 280 pages. A thousand years ago, European coastal dwellers began using the unfailing energy from the...

Hammerfest, Norway, with 11,000 inhabitants, calls itself the world's northernmost town. In December, tidal currents started turning the blades of a windmill-like turbine standing on the seabed near Kvalsund at the Arctic tip of the country. "We will be the first in the world...

China has released a draft of a long-awaited energy law that calls for the country to keep larger reserves of oil, uranium and other key resources and to set up a new government department.But the draft law makes scant mention of measures needed to counter...

The British government on Thursday approved construction of the first new nuclear power plants in a generation, saying atomic energy could help fight climate change and secure the country's energy supplies in an increasingly unstable world.Britain joins a growing list of countries rethinking the long-unpopular...
