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
