Power electronics modify the voltage, current or frequency of electricity in applications as diverse as solid-state lighting, intelligent motors and electric vehicles.
Even Thomas Edison bet badly, as in his development of direct-current electricity that proved inferior to alternating current.
Fully exploiting wherever practical the best available efficiency techniques throughout the U.S. economy could save half our oil and gas use, and three-fourths of our electricity, at about an eighth of their current price.
Although there are easily enough dammable rivers to double the current electricity supply, many of the best sites are in remote Amazonia.
The Waxman-Markey bill that passed the House on Friday by a 219-212 margin will punitively tax energy sources that contribute 90% of current U.S. electricity (or 71% if you want to leave out nuclear).
Almost all of the electricity moved over grids is in the form of alternating current.
On top of that, the state has upped its current portfolio mandate to require that renewable fuels supply 33 percent of its electricity by 2020.
FORBES: Cap & Tax: California's Recipe To Feed The Texas Economy
At current growth rates data centers will consume 3% of global electricity supply by 2010.
The International Energy Agency forecasts that the world will consume 28 trillion kilowatt-hours of electricity in 2030, nearly twice the current level of consumption.
The demand for energy in the form of electricity and fuel is larger than its current supply in several parts of the world, particularly in developing countries.
FORBES: GE Is Well Positioned To Ride Rising Global Energy Demand
Its high-voltage direct current system is delivering electricity to the British Petroleum platform in the middle of the ocean.
If economic growth carries on at the current rate in China, it will require up to 1, 000 gigawatts of new electricity generation in China.
Analysts say that in order to meet the 2030 target - which Mr Cameron said he "basically endorsed" last year - only about 10% of UK electricity can come from gas-fired power stations emitting at current levels.
The current pylons used are about 25m (82ft) but the higher pylons would be capable of transmitting more electricity.
When something that conducts electricity sweeps through a magnetic field, a current starts to flow through it (this is the basis of a dynamo).
When a current flows in such a wire, the electrons that flow as electricity are forced to align their spins to those of the local atoms embedded in the wire.
The rest amounted to little more than extensions and expansions of current policy that would have to be approved by Congress, including doubling the tax credit for producers who make electricity from wind, biomass and landfill methane, the Gore campaign said.
