ENERGY CRISIS IS A COMMON PROBLEM,PEOPLE AROUND THE WORLD NEED AND USE ENERGY FOR THEIR CARS,WE NEED AND USE ENERGY FOR OUR HOME,WE NEED AND USE ENERGY FOR OUR BUSINESS.EVERYBODY IN THE WORLD DEPENDS ON IT.WITH THE PRICES  of oil climbing EACH DAY ON THE INTERNATIONAL MARKET, SO MANY PEOPLE DO NOT KNOW HOW TO COPE WITH THAT PROBLEM. IS NOT THERE A SOLUTION, AN ANSWER TO OUR ENERGY PROBLEMS TODAYS?

Renewable energy (also called green energy) is a renewed energy or regenerated naturally on the scale of a human life. Renewable energy is derived from natural, regular or constant, caused by the stars. They come from:

Mostly sun radiation, water cycle, wind, photosynthesis, ...

The internal heat of the Earth (from itself to the radioactivity of elements such as uranium, thorium and potassium): Geothermal

Own the rotation of the Earth relative to the Earth-Moon system, ie tidal power.

Wood, solar, hydro and wind power come from solar energy. Only geothermal and tidal energy are exempt from this rule.

Oil, natural gas and coal are not renewable energy: it took millions of years for life on Earth is the stocks of fossil energy that we consume today. Similarly, the issue of nuclear fission of uranium atoms, can not be regarded as renewable energy, uranium mining is limited.

The renewable energy depends on the speed at which the source is regenerated, but the speed at which it is consumed. Thus, wood is renewable as long as abat fewer trees it grows, and that the forest continues to play its vital ecological functions

Provided by the sun, wind, heat from the earth, waterfalls, tides or the growth of plants, renewables do little or no waste or emissions. They participate in the fight against the greenhouse effect and releases CO2 into the atmosphere, facilitate the management of local resources, generate jobs. Solar (solar photovoltaic, solar thermal), hydro, wind, biomass, geothermal energy is inexhaustible flow from the "energy stocks drawn from the deposits of fossil fuels being scarce oil, coal, lignite, natural gas. Enter the world of renewable energy: What sources of energy? What needs? How to capture, transform? What form to use? How to reduce 80%of electricity bills?Renewable energy is really the answer of energy crisis in our world today.
