Time has come for tidal energy

One of the knocks against "green" energy is that its generating capacity tends to be too intermittent. When the wind doesn't blow, it pulls the plug on windpower. And solar panels won't collect energy once the sun goes down. But a green energy source that is predictable is tidal power. Charts accurately reveal when tides ebb and flow.

Energy From the Restless Sea

A group of entrepreneurs is harnessing the perpetual motion of the ocean and turning it into a commodity in high demand: energy. Right now, machines of various shapes and sizes are being tested off shores from the North Sea to the Pacific — one may even be coming to the East River in New York State this fall — to see how they capture waves and tides and create marine energy.

Radical turbine aims to take wind power to towns and cities

The designers say they may have overcome two drawbacks of traditional turbines. The turbine's triple helix form and vertical axis are said to make it almost silent, and it is believed to perform better in urban areas, where wind direction can vary by the minute. While there are other vertical-axis turbines, this is believed to be the first with three blades.

The allure of deep-water wind power

Compared to conventional shallow water offshore wind farms that cost about $2 million per MW installed, the fixed-pile foundation Talisman project at $5.8 million per MW is almost three times as expensive and prohibitively uneconomical in the near term.

Tidal energy heads to market

Advocates of tidal energy say it is more reliable than the other marine technology, wave power. Unlike wave - and wind - farms, tides are predictable. The devices use technology similar to wind farms or hydropower, with underwater turbines being driven by the force of the tide to generate electricity.
