Information about green energy, more information on renewable energy and impacts of wind turbines.
The term ‘green energy’ usually refers to renewable forms of energy which can be harnessed through various technologies. Green energy is replenished constantly as it is derived from natural sources. Examples include:
Green energy is unlikely to be completely ‘emission free’. This is because greenhouse gases may be released during the manufacture, transportation and installation of the technology needed to harness the green energy, such as the electric pump needed to operate an air source heat pump. In general, however, emissions will be much lower than if we burn fossil fuels to produce the same amount of energy.
Renewable energy technologies like wind turbines, photovoltaic and thermal solar panels, and biomass heaters offer an alternative to fossil fuels. They can help you to reduce your energy bills and carbon dioxide (CO2) emissions. By investing in a renewable energy technology, you can pre-buy energy at today’s prices for a future where energy may cost a lot more. If fuel prices rise, your pay back will happen even sooner than first expected. The two schemes which provide financial payback for installing renewable technologies and generating your own electricity and heat are detailed below:
The FiTs scheme provides you with a fixed payment for generating electricity at home (the ‘generation tariff’). It also pays for any unused electricity that you export to the national grid (the ‘export tariff’). You also benefit by not having to pay for the electricity that you generate and use yourself. The amount you are paid is known as the tariff level and will vary depending on the scale and type of generator you install.

The RHI scheme provides similar financial incentives for the generation of heat on a micro-scale. It embraces technologies such as solar thermal heating for water and biomass boilers.
