Today, more than half of the electrical power energy generated in the world comes from coal. For the foreseeable future, coal will continue to be the dominant fuel used for electric power production. The low cost and abundance of coal is one of the primary reasons why consumers benefit from some of the lowest electricity rates of any free-market economy.
The key challenge is to remove the environmental objections to the use of coal in tomorrow’s power plants. New technologies being developed in the Fossil Energy program could virtually eliminate the sulfur, nitrogen, and mercury pollutants released when coal is burned. It may also be possible to capture greenhouse gases emitted from coal-fired power plants and prevent them from contributing to global warming concerns.
Research is also underway to increase the fuel efficiency of coal-fueled power plants. Today’s plants convert only a third of coal’s energy potential to electricity. New technologies in Energy’s Fossil Energy program could nearly double efficiency levels in the next 10-15 years. Higher efficiencies mean even more affordable electricity and fewer greenhouse gases.
While coal is the nation’s major fuel for electric power, natural gas is the fastest growing fuel. More than 90 percent of the power plants to be built in the next 20 years will likely be fueled by natural gas. Natural gas is also likely to be a primary fuel for distributed power generators – mini-power plants that would be sited close to where the electricity is needed.
Energy’s Fossil Energy program is developing natural gas-powered fuel cells for future distributed generation applications. Fuel cells use hydrogen that can be extracted from natural gas or perhaps in the future from biomass or coal.
R&D programs aimed at maintaining the operating capability of the nation’s existing nuclear power plants and developing the next generation of nuclear technologies. Nuclear energy is the world’s largest source of emission-free electricity. The Nuclear Energy program is working to develop cost-efficient technologies that further enhance nuclear safety, minimize the generation of nuclear waste, and further reduce the risk of proliferation.
To meet the rising electricity enery power demand of the 21st century, significant improvements in America’s electric system are necessary. Blackouts serve as a powerful reminder of the critical role electricity plays in the everyday lives of people.
Voltages, currents, power energy
When it comes to electric current, electrical voltage, electric circuit dynamics and energy powers, all rely on the flow of the electron. What this means is that electric power voltage feeds loads, solid state power load devices, and other loads that need electric power. The electric power watt is the way that power is measured.
Electrical Engineers and Scientists alike seek common views in order to develop new technologies for the storage of energy and the transmission of energy through power circuits that will contribute to energy efficiency of the electric industry. For instance, the copper wires used in typical transmission lines lose a percentage of the electricity passing through them because of resistance, which causes the wires to heat up. But "superconducting" materials have no resistance, and if they are used to transmit electricity in the future, very little of the electricity will be lost.
This 100+ page e-book is a great guide for those who have a basic interest in the field of electricity. This well-illustrated e-book, coupled with some basic knowledge of electricity, will give you a broad theoretical background in this fundamental subject.CONTENTS
