The need for new ways of producing energy in the world today

Continuing this downward trend in energy intensity depends in part on the nation taking advantage of numerous opportunities for efficiency advances in current technology.

Renewable Energy

This form uses the gravitational potential of elevated water that was lifted from the oceans by sunlight. New York State could end fossil fuel use and generate all of its energy from wind, water and solar power, according to Mark Jacobson.

The triboelectric effectpiezoelectric effectand even direct capture of the energy of nuclear decay Betavoltaics are used in niche applications, as is direct conversion of heat to electric power in the thermoelectric effect.

Multiple parallel efforts will be needed, and that recognition has prompted intense interest in a wide variety of new technologies. This form of energy can lessen the need for other power to maintain comfortable temperatures in buildings, but cannot be used to produce electricity.

The other is to provide redundancy by placing two or more mirrors in orbit for each receiving location on the ground.

These energy sources are often non-centralized, leading to greater consumer control and involvement. They generate power by burning natural gas in a gas turbine and use residual heat to generate steam. The chemical energy stored in the coal is liberated in combustion, generating heat that is used to produce steam.

A very small proportion of electric power distributed by utilities is provided by batteries. At present, total world consumption is approximately 85 MBD, 21 million of which is used by the United States. For example, recent advances in nanotechnology, applied to the lithium ion battery, may permit significantly more energy to be stored in a smaller, lighter package.
