  GEM: about green electricity
In the UK about two thirds of our electricity is generated by burning coal and gas in power stations.
'Green electricity' means electricity produced from sources which do not cause these impacts upon the environment.
In some cases the energy is being used to generate electricity.

  Electricity - Wikipedia, the free encyclopedia
Electric power: electrical energy as it is delivered to individual, commercial and industrial customers for use in operating equipment, and providing heat and illumination.
Electric charge is a property of certain subatomic particles (e.g., electrons and protons) which interacts with electromagnetic fields and causes attractive and repulsive forces between them.
Electric charge gives rise to one of the four fundamental forces of nature, and is a conserved property of matter that can be quantified.

 Green energy - Wikipedia, the free encyclopedia
Green energy is a term used by some environmentalists to describe what they deem to be environmentally friendly sources of power.
For green energy to be truly "ecological electricity" it must not include medium or large-scale hydroelectric power or sources of air pollution such as burning biomatter or petroleum.
In several countries, current electricity retailing arrangements make it possible for consumers to buy green electricity, either by purchasing their electricity from a generating company that uses only renewable technologies, or by buying from a general supplier who undertakes to buy at least as much power from renewable sources as their "green" customers purchase.

 Electricity
Electricity is a property of certain subatomic particles, such as electrons and protons, that gives rise to attractive and repulsive forces between them.
The late 19th and early 20th century produced such giants of electrical engineering as Samuel Morse, inventor of the telegraph; Alexander Graham Bell, inventor of the telephone; Thomas Edison (inventor of the phonograph and a practical incandescent light bulb); George Westinghouse, inventor of the electric locomotive; Charles Steinmetz, inventor of alternating current.
In electrical engineering, the energy in electromagnetic fields is harnessed to perform useful work—either as a method to transmit energy to the appropriate place and then convert it back into a different, useful form of energy (for instance, heat, light, or motion), or by using the presence or level of electricity to convey information.

The electric chair ran on Westinghouse's AC; Edison wanted to prove that AC power was capable of killing, and should therefore be viewed by the public as inherently dangerous.
Electric power, for most consumers, is generated centrally by utility companies using coal, oil, hydropower, or nuclear power.
Rather than using the word electricity to refer to the quantity of electric charge, many sources instead say that electricity is the quantity of electromagnetic energy measured in joules or kilowatt-hours.

R is the resistance, measured in ohms The ohm (symbol: Ω) is the SI unit of electric resistance.
Electrical resistance is a measure of the degree to which an electrical component opposes the passage of current.
In the analysis of an alternating-current electrical circuit (for example a RLC series circuit), reactance is the imaginary part of impedance, and is caused by the presence of inductors or capacitors in the circuit.

 Public Citizen | Publications - Green Buyers Beware
Most green products on the market have no positive impact on the environment because most marketers are merely reselling renewable energy that other consumers are already paying for and that would continue to operate regardless of any resale to green consumers.
Since most green pricing or green marketing programs in the country have response rates of only 1% to 2%, the resale of utility power is unlikely to increase the supply of renewables.
Only one small green marketer (San Jose-based cleen 'n green energy) purchases power exclusively from renewable energy producers that are not owned or under contract to a utility and that would otherwise receive only the market rate for their power.

Both options ensure that green electricity is generated for the grid on your behalf.
Every 1,000 kilowatt hours of electricity generated from the wind and sun uses virtually no water and keeps 1,400 pounds of carbon dioxide out of the atmosphere, as compared to a coal-burning steam plant.
For an extra 2 cents a kilowatt hour, Green Tags ensure that electricity is generated by certified wind and solar facilities and delivered to a Western grid.

 The National Energy Foundation - Energy Advice - Green Electricity
This is where every unit of electricity bought by a consumer is generated from a renewable energy source.
Green energy can be loosely defined as energy from renewable or sustainable sources.
Conventional forms of electricity produce emissions in the manufacture of electricity, such as sulphur dioxide and carbon dioxide.

 MeIPL - Green Electricity - Sustainable   (Site not responding. Last check: )
Green electricity comes from a variety of sources, including hydropower dams, wind farms, photovoltaic arrays, solar concentrators, geothermal turbines and biomass facilities (which burn wood chips, methane from municipal garbage, etc.).
Unlike uranium or fossil fuel (natural gas, oil, and coal), the energy sources for green electricity are continually renewed by natural processes.
Ultimately, the energy for all types of green electricity comes from solar radiation, the gravitational pull of the moon, or the heat of the Earth's core.
