renewable energy

   

Today our power stations burn fuels such as gas and coal. This combustion process releases harmful gases including CO2. Each UK household pumps out 6 tonnes of CO2. To slow the rate of climate range, the government want to reduce CO2 emissions by 20% by 2010. If every household in the UK made their homes energy efficient we would save £6.5 billion a year in energy bills, up to £300 a household. We would reduce CO2 emissions by 25 million tonnes a year. CO2 is the main cause for climate change and freak weather conditions, Scotland is becoming windier and wetter and is now 4 times more likely to be threatened by flood. Burning fossil fuels is not only harmful to the environment it is also inefficient.

A reduction in the emissions arising from urban activities demands a combination of energy efficient measures and a move away from fossil fuel sources. Progress may be enabled by the use of advanced materials and control systems and the adoption of renewable energy conversion technologies. Building-integrated NRE systems( photovoltaic components, small-scale wind power, micro-gas turbines, fuel cells, solar thermal devices etc.) have the potential to make a significant contribution towards the attainment of targets for reduced gaseous emissions. New approaches to system figuration, component sizing and power utilisation are required in order to maximise the efficiency of energy use while not adversely affecting the quality of power available from the public electricity supply or local building network.
