Why renewables?
"One of the things I don't want to do is to look at my grandchildren and hear them say: "Grandfather, you knew it was happening - and you did nothing." "
David Attenborough, Wed 24th May, 2006, The Independent.
Change is never a comfortable thing, but sometimes it is necessary. It is now widely accepted, that human activity since the birth of industrialisation has been responsible for the climatic changes that we are all experiencing, and that these climatic changes are far and above any natural variations that we have seen in the planet's past.
The latest figures from the Intergovernmental Panel on Climate Change (IPCC) show that average global temperatures have risen by 0.760ºC over the 20th Century. Evidence is now almost unequivocal that this is as a result of the emission of greenhouse gases, such as carbon dioxide (CO2), methane, nitrogen oxides and sulphur hexafluoride building up in the atmosphere.
Of all greenhouse gases, CO2 actually has the weakest global warming effect but the scale of its emission, means that it is the biggest contributor to the problem. CO2 emissions come primarily from transport, business, households and the combustion of fossil fuels in electricity generation. So to reduce our future impact on our planet and its ecosystems it is essential that we develop and install new and clean sources of energy for the future.
