The new proposals outlined by the White House today would allow companies to write off the costs of new, more efficient generators at a faster rate.

There were still problems with efficient generators and high voltage transformers.

I think that physics here may be a little ahead of anywhere else in the system, but we still don't have an efficient generator.

New, more efficient gas-fired generators made natural gas not only a cleaner alternative to oil and coal for power plants but often cheaper, too.

G.M.'s two new hybrid vehicles include one that uses an electric motor charged by an efficient gas-turbine generator.

A scientific understanding of electricity was necessary for the development of efficient electric generators, motors and transformers.

Regional power companies continue to use old generators, leaving more efficient generators at the national power stations idle or underused.

To the Editor: Independent power producers have over the last decade become this country's most efficient generators of electrical power.

But over time, he said, savings in the purchase of power will be more important as less efficient generators are driven from the market.

Portland General is one of the most efficient generators in the nation.
