Renewable Energy Sources
What is meant by Sustainable Development?
“Development which meets the needs of present, without
compromising the ability of the future generation to meet their
own needs”
Why RES? Clean Source of Energy Abundant Sources – Do not get depleted No harmful waste products Many type can be generated at the
location of use – No transmission Maintain reliability of supplies Competitive markets Ending fuel poverty No Green House gases
Why not Fossil Fuels?
Depleting supplies Pollution Green house gases Dependent on Other Countries Less Efficient Will become more expensive
UK Renewable Target
2010 10% of electricity generated from renewable sources
Doubled by 2020 National targets backed up by regional
targets
Benefits of RES
Most Renewable cost little more than conventional sources – Wind
Most renewable don’t have volatile price, since the fuel cost is nil/negligible
Most renewable have the advantage of Environmental benefits Waste Management benefits Economic Development benefits
Why Developed countries Pursuing RES?
Economic Development Price Stability Fuel diversity to increase reliability Environmental benefits
Limitations of RES
Solar only in Daylight Wind speed highly variable Solutions not yet developed fully Storage technology being considered
