“I’m no longer sceptical…..climate change is the major challenge facing the world.”
Sir David Attenborough
"Britain faces 'oil crunch' within five years", Richard Branson and other business leaders warn it could be more serious than the financial crisis.''UK competitiveness will be hampered unless we can develop viable, affordable and secure long term sources of alternative energy''
Energy Security
The UK consumption of energy and the sourcing of electricity supplies are changing. As our energy consumption increases, our dependency on imports, such as gas from Russia, increases. The UK became a net importer of energy in 2004 and our dependency on imports rose to be 20% of usage 20% in 2006 and 20071. With North Sea oil and gas reserves depleting, this dependence is likely to continue. As global demand for fossil fuels increases, so too does the price, which results in a higher cost for our electricity.
Solar Farms do not have to purchase fuel and therefore help to keep electricity costs down in high fuel price environments.
Power Stations
Many of the UK's nuclear and coal power stations are old and near the end of thier intended life. The previous government did not start building new ones in time, and as the UK's electricity demands rise, there are risks that generation capacity will not keep up with demand. The UK is now in the situation where there is not time to build new traditional power stations before the old ones are due to be turned off. This could start affecting people across the UK with electricity price increases and potentially rolling brown outs.
Solar farms are the fastest way to deply significant amounts of new power generating capacity across the UK.
Climate Change
The UK has a significant input into global CO2 emissions. When broken down to CO2 emissions per capita, the UK is even more of a significant CO2 emitter when put alongside other countries3.Traditional methods of generating electricity from fossil fuels release harmful carbon dioxide (CO2) which contributes to climate change. Evidence of climate change is being witnessed every day:
• 23 of the 24 warmest years, since records began in 1850, have occurred since 1980
• Sea levels have risen by an average of 3.1mm per year over the period from 1993 to 2003
• The incidence of major floods, the number of wildfires, average wind speeds and the frequency of cyclones around the world have all risen in the past two decades2
If we are to address global warming, developed countries such as the UK have to lead and reduce their per capita emissions so that they can encourage the developing world to follow. But the UK is the laggard of Europe, we have missed the 2010 targets and we are not on track to hit our 2020 targets.
Solar Farms help reduce the threat of climate change by generating carbon-free electricity, replacing generation by coal and gas-fired power stations. A single 1 hectare solar farm deployment can prevent the release of over 200,000kg of CO2 per annum.
