Abstract
A solar energy converter includes: a light-concentrating instrument; an electron emitter in an insulated vacuum vessel, emitting electrons in a vacuum as a temperature rises by sunlight; an electron accelerator within the light-concentrating instrument; a cathode on a surface of the electron emitter opposite to a surface which is irradiated by sunlight, and electrically connected with the electron emitter; an electric field supplier having a positive terminal and a negative terminal; and an electron collector in the vacuum vessel, collecting the emitted electrons flying from the electron emitter toward the electron accelerator; wherein the electron accelerator is connected with the positive terminal and the cathode is connected with the negative terminal to generate an electric field, and the electron collector is used as a negative generator electrode and the cathode is used as a positive generator electrode in which the collected electrons migrate to the electron emitter to generate electricity.

The EU use various sorts of power, ranging from fossil fuels to renewable energy: coal, gas, solar thermal, hydro, wind, nuclear.

If you want the names of a few major power companies…

RWE npower is one of the UK’s leading electricity generators. Its parent company, RWE is one of the leading international utility companies. The company provides customers with electricity, gas and water as well as services related to these products. The company’s core markets are Germany, the UK and Continental Europe.

There are other national energy supply companies such as Eon in Germany and Gaz de France. There is also the power supplier E.ON UK.

In addition, EDF already has a significant presence in the UK energy market with its purchase of London Energy, Seeboard Energy and SWEB Energy. The company operates 58 atomic reactors in France and is expected to be among those firms bidding to build the new nuclear plants.

The E.U. Already imports half of its energy. By 2030 that figure is set to rise to 70 percent. While Europe has managed to reduce its dependence on oil since the crises of the 1970s, imports still account for three quarters of oil consumption and are expected to approach 90 percent by 2030. In Europe, natural gas is expected to be the largest energy source after oil, but before coal and lignite. Already 15 percent of electricity comes from gas power stations.

At present, nuclear power generates 35 percent of electricity within the E.U. The popular alternative to coal for electricity generation is natural gas. Already 15 percent of electricity comes from gas power stations, and this is expected to rise to 40 percent by 2030.
