Not exact matches

«New off - shore turbines, with blades the size of the London Eye, need to be built and launched from modern docks, so we need to upgrade our shipyards to take advantage of this massive opportunity,» he said.

Biello: And they do have some more aggressive policies than even the U.S. at present as far as renewable energy goes, whether those who actually realized they have had a lot of problems with kind of wind farms that didn't perform up to expectations, but they do have fairly aggressive targets for how much energy it needs to come from renewable resources like the wind and the sun, they have become the manufacturer, as in all things, for Photovoltaics and the wind turbine blades that are basically powering the green revolution in the West.

The differences between wind turbine and ceiling fan blades arise from the contrasting design criteria: the wind turbine is intended to capture high - velocity wind to generate electricity efficiently; the ceiling fan needs to move air at low velocity with inexpensive components.

Though small by today's standards — the wind turbine's blades were less than one third the length of those installed offshore by Deepwater Wind — the 200 kilowatt - capacity turbine produced as much as 11 percent of the island's energy needs during off - peak winter months.

No mention of course, that wind turbines need a constant backup source of energy, usually in the form of a conventional power plant, or that the production of these hundred - ton industrial machines creates one ton of hazardous and toxic waste PER turbine blade (according to a report from VESTA wind turbine manufacturer).

60 Wind Generation Historically Small wind turbines used for Wind Generation Historically Small wind turbines used for agriculture use — pump water Provide electrical needs for isolated homes Extracts ~ 3 kW of power with wind vanes no larger than 1m long Modern Wind turbines with vanes larger than 50 m can extract megawatts of power from the wind Blades designed to function similar to airplane wings utilizing lift created by the wind flowing over the surface to turn the blades — more efficient Turbines mounted on tall towers or at sea can take advantage of higheturbines used for Wind Generation Historically Small wind turbines used for agriculture use — pump water Provide electrical needs for isolated homes Extracts ~ 3 kW of power with wind vanes no larger than 1m long Modern Wind turbines with vanes larger than 50 m can extract megawatts of power from the wind Blades designed to function similar to airplane wings utilizing lift created by the wind flowing over the surface to turn the blades — more efficient Turbines mounted on tall towers or at sea can take advantage of higheturbines used for agriculture use — pump water Provide electrical needs for isolated homes Extracts ~ 3 kW of power with wind vanes no larger than 1m long Modern Wind turbines with vanes larger than 50 m can extract megawatts of power from the wind Blades designed to function similar to airplane wings utilizing lift created by the wind flowing over the surface to turn the blades — more efficient Turbines mounted on tall towers or at sea can take advantage of higheturbines with vanes larger than 50 m can extract megawatts of power from the wind Blades designed to function similar to airplane wings utilizing lift created by the wind flowing over the surface to turn the blades — more efficient Turbines mounted on tall towers or at sea can take advantage of higher Blades designed to function similar to airplane wings utilizing lift created by the wind flowing over the surface to turn the blades — more efficient Turbines mounted on tall towers or at sea can take advantage of higher blades — more efficient Turbines mounted on tall towers or at sea can take advantage of higheTurbines mounted on tall towers or at sea can take advantage of higher winds.

This is due to the fact that wind turbines need to be high in the air to reach the higher - speed winds, and in order to harness those winds, the blades need to be large.
