Solar
Energy
Solar energy can be captured by solar
panels. There are 2 main types of solar panels which uses complete different
technologies to make use of the energy from the sun:
- Solar Water Heating
collectors: These panels absorbs the energy from the sun and transfer it to
heat water.
- Photovoltaic or solar
electric panels: These panels transform the solar radiation directly into
electricity.
For maximum efficiency,
solar panels should be mounted on a south facing roof at a 30° angle with the
horizontal and away from any shadows from trees, surrounding buildings or
chimneys.
Wind
Power
People have used the power of the wind for many years to produce mechanical
power for milling grain and pumping water. In recent times wind turbine
technology has enabled us to harness wind to generate electricity. The
electricity is then exported either to the grid for use locally or to power a
stand alone application.
This renewable source of
energy has great potential in both onshore and offshore wind farms. Wind power
is one of the cleanest and safest of all the renewable commercial methods of
generating electricity. The UK has the largest wind resource in the whole of
Europe.
Hydropower
The energy potential of moving water has been harnessed for thousands of years,
originally using water wheels to drive mills and machinery. Hydropower currently
produces 2% of the UK electricity needs. Whilst most of this comes from large
dam projects installed many years ago, there is still an untapped small
hydropower potential in certain parts of the UK.
Biomass Energy
Biomass is a collective term for all plant and animal material. A number of
different forms of biomass can be burned or digested to produce energy. Examples
include wood, straw, poultry litter and energy crops such as willow and poplar
grown on short rotation coppice and miscanthus. Biomass is a very versatile
material and can be used to produce heat (for space and water heating),
electricity and a combination of heat and power (electricity). The UK has some
of the largest examples of the use of Biomass to generate electricity in Europe.
Geothermal
Geothermal energy is the heat of the
Earth, which can be tapped into to produce electricity in power plants, and to
use its warm water for industry, agriculture, bathing and cleansing. Although in
use worldwide, its potential as an energy source is not fully utilised, thus
geothermal offers a real option in future environmentally-friendly energy
supply.
