The roadmap describes a strategic vision as to how every type of green energy industry can be grown in the UK. Each method has its problems and limitations, but it is hoped that in combination they will be able to deliver the targets that have been set for 2020.

Onshore Wind
Onshore wind farms are the most visible of the alternative power generation methods. There is certainly no shortage of wind in the British isle, and turbines have become a common addition to the landscape. Wind turbines are not popular among those that live near them due to noise and can be detrimental to birdlife.
Offshore Wind
By putting wind turbines out at sea a lot of problems are reduced. Nobody is around to complain about the noise, and the winds are consistent. The disadvantage is the increased cost of placing and maintaining the turbines, which is much more difficult than if they were on land.
Marine energy
It has long been a dream to harness the power of waves and tidal energy, The technologies around this are in their infancy, but Britain is among the world leaders in bringing these projects to practical fruition. There are ecological concerns around constructing barriers in tidal estuaries, but tidal power is very predictable and reliable.
Biomass energy
If you stick your hand into the middle of a compost heap to will find that it is very hot in there. This is because when bacteria break down plant matter they generate a lot of heat as a bi-product. By using specially selected and engineered algae and bacteria it is hoped that it will one day be possible to use this principle to generate large amounts of clean power.
Ground source heat pumps
A ground source heat pump transfers heat from the ground. Because in winter the temperature underground is higher than the ambient air temperature, this can be exploited to improve the efficiency of heating systems. It is also possible to generate electricity using geothermal heat. This can only be done economically in certain geologically active places.
