writes here: Renewable energy (sources) or RES capture their energy
from existing flows of energy, from on-going natural processes, such as
sunshine, wind, wave power , flowing water (hydropower), biological
processes such as anaerobic digestion, and geothermal heat flow.
The most common definition is that renewable energy is from an energy
resource that is replaced by a natural process at a rate that is equal to
or faster than the rate at which that resource is being consumed.
Renewable energy is a subset of sustainable energy.
Most renewable forms of energy, other than geothermal and tidal power,
ultimately derive from solar energy. Energy from biomass derives from
plant material produced by photosynthesis using the power of the sun. Wind
energy derives from winds, which are generated by the sun's uneven heating
of the atmosphere. Hydropower depends on rain which again depends on
sunlight's power to evaporate water.
Since new stuff is developed almost every day I wont even try to keep
updating this pages with the latest achievements so best check out
Alternative Fuel News
here from Sciencedaily.com
Shell
informs here on Alternative energy sources such as Wind energy, Solar
energy, Biofuels, Hydrogen, Geothermal Energy, Biomass, Hydro-electricity.
And much more websites with information on
alternative, renewable energy related websites can be
found here in the google directory and here:
