Green
energy includes natural energetic processes which can be harnessed
with little pollution. Anaerobic digestion, geothermal power,
wind power, small-scale hydropower, solar power, biomass power,
tidal power and wave power fall under such a category. Some
versions may also include power derived from the incineration
of waste.
Green energy is a term describing what is thought to be
environmentally friendly sources of power and energy. Typically,
this refers to renewable and non-polluting energy sources.
Switching to green energy is an easy and flexible way to reduce
environmental impacts and to protect climate. But safeguards
are needed to ensure that final consumers’ contributions
really make a difference.
Solar Energy
The quantity of sunlight reaching the surface of the earth
is approximately 3000 times the total amount of energy used.
Wind power
Wind power is the world's fastest growing energy source.
Wind generated electricity is now often competitive with traditional
coal-fired and nuclear power stations.
Biomass
Agricultural and forestry material or specially grown crops
can be used as a renewable energy source, which can create
new opportunities for farmers.
Tidal power
Tidal power is predictable. However, many suitable areas
are in environmentally sensitive locations and any schemes
must assess the potential changes to the marine ecosystem.
Hydro power
Although most of the possible sites for large hydropower stations
in Europe have already been developed, there is still a large
potential for smaller schemes.
Geothermal
Geothermal energy comes from hot rocks deep underground. This
heat can be used to generate steam and thus drive turbines
for electricity or used directly to provide hot water and
heating.
