- Advantages and Disadvantages of possible futures
- Business as usual (forecasts predict by 2030)
- Global primary energy demand will rise by 53%
- Fossil fuels will remain the dominant source of energy worldwide
- Emissions from electricity generation will account for 44% of energy-related emissions
- Over 70% increase in the energy demand will come from developing countries due to rapid economic growth and population growth
- Nuclear
- By 2008, 439 nuclear reactors were supplying 15% of the worlds electricity
- Does not produce greenhouse gas emissions
- Uranium is relatively cheap to mine and reserves should last around 150 years
- Very cost effective transport as only used in small quantities
- Produces 1% of global electricity supply
- 1986 Chernobyl incident highlights the issues
- Very expensive to build-several billion pounds
- Nuclear waste disposal is an issue as it remains radioactive for 10,000years
- Renewable energy with the emphasis on wind power
- Costs of generating wind today are about 10% of what they were 20 years ago
- In some areas first generation wind turbines are being replaced with modern turbines which give better peformance
- NIMBY- people are concerned that turbines could blight their homes and views
- Suitable areas are often near the coast where land is expensive
- Energy Conservation
- Combined Heat and Power - power stations waste 65% of the heat they generate
- CHP plants can be up to 95% efficient as they can use different fules in the same boiler and cut emisssions
- Green Taxation
- aimed at cutting the use of natural resources and encouraging recycling
- Combined Heat and Power - power stations waste 65% of the heat they generate
- Business as usual (forecasts predict by 2030)
