2. 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”

4. 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

5. Why not Fossil Fuels?
 Depleting supplies
 Pollution
 Green house gases
 Dependent on Other Countries
 Less Efficient
 Will become more expensive

9. UK Renewable Target
 2010 10% of electricity generated from
renewable sources
 Doubled by 2020
 National targets backed up by regional
targets

10. 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

11. Why Developed countries
Pursuing RES?
 Economic Development
 Price Stability
 Fuel diversity to increase reliability
 Environmental benefits

12. Limitations of RES
 Solar only in Daylight
 Wind speed highly variable
 Solutions not yet developed fully
 Storage technology being considered
