Sentences with phrase «electricity transmission cables»

Based on wind - speed measurements, researchers at MIT, led by Stephen Connors, director of the Analysis Group for Regional Electricity Alternatives, calculated that large turbines located far offshore could ultimately cost less per power generated than either land - based turbines or near - offshore ones, even factoring in extra costs, such as much longer underground electricity transmission cables.

An airplane flies through low cloud above high tension electricity transmission cables and barbed wire in Sydney November 24, 2009.

To give one example, the U.K.'s National Grid — which operates the electricity transmission network in England, Wales and Scotland — says its networks are made up of approximately 4,474 miles of overhead line, 932 miles of underground cable, and 342 substations.

In his 2001 testimony to the congressional committee on energy, Peterson estimated that 10 % of the electricity generated in the United States is lost annually due to the resistance in copper and aluminum power - transmission cables.

One transmission cable running along the seafloor would send electricity to the shore by connecting to the Morro Bay substation owned by Pacific Gas and Electric.

The resulting electrical current travels via underground cables to a substation, where it is converted to a higher voltage for the larger electricity transmission or distribution grid.

Development of high voltage direct current cables and transmission systems — Although initial loss of electricity of DC cables is higher than for AC, there is no incremental loss of electricity as the length of the cable increases, making it possible to build offshore wind farms in very windy areas and transmit the energy over vast distances to areas with poor wind regimes, and to combine wind generators from different areas to reduce the impact of low - wind days and the need to use backup hydrocarbons on those days
