  Encyclopedia: Renewable energy source   (Site not responding. Last check: 2007-10-18)
Renewable energy (sources) or RES includes all sources of energy that are captured from on-going natural processes, such as solar power, wind power, water flow in streams (hydro power), biomass, biodiesel and geothermal heat flows.
Renewable energy sources are fundamentally different from fossil fuel or nuclear power plants because of their widespread occurrence and abundance - the sun will 'power' these 'power plants' (meaning sunlight, the wind, flowing water, etc.) for the next 4 billion years.
Since most renewable energy is "Solar Energy" this term is slightly confusing and used in two different ways: firstly as a synonym for "renewable energies" as a whole (like in the political slogan "Solar not nuclear") and secondly for the energy that is directly collected from solar radiation.

 Encyclopedia of Desalination and Water Resources: Why Use Renewable Energy for Desalination
Recently, considerable attention has been given to the use of renewable energy as sources for desalination, especially in remote areas and islands, because of the high costs of fossil fuels, difficulties in obtaining it, attempts to conserve fossil fuels, interest in reducing air pollution, and the lack of electrical power in remote areas.
The coupling of renewable energy sources with desalination processes is seen by some as having the potential to offer a sustainable route for increasing the supplies of potable water.
The amount of energy used in the world for desalination is comparable to the total energy requirement of an industrialized country such as Sweden.

Taking a look at the installed capacity of different renewables the picture becomes much clearer: In 2001, more than 69 GW of solar thermal capacity were installed world wide — compared with 23 GW of wind power and 1.1 GW of photovoltaic (PV).
This comparison is especially interesting as they all are ‘intermittent’ renewables, whose actual energy output fluctuates depending on solar radiation or wind speeds.
With 69 GW of installed capacity, solar thermal is already today one of the leading renewable energy sources worldwide.
