2. From the Spec: 3.1: There is uncertainty over both global energy supply in terms of reserves (e.g. peak oil and gas) and demand (economic growth rates, conservation of resources, a switch to renewable sources, population change) Investigate: A range of energy supply and demand projections Economic projections based on the projections

3. For each factor consider what the effect would be on global energy if (a) it went up, (b) it went down, (c) it stayed the same e.g. if China and India’s economies keep growing, slow down or stay the same

6. From the Spec: 3.2: There are different responses to increasing energy demands – such as ‘business as usual’ reliance on fossil fuels or the adoption of alternative sources such as nuclear, or wind power. Each has costs and benefits, such as future climate change, and local opposition. Weigh up the advantages and disadvantages of contrasting energy options in terms of: Technical feasibility Economic impacts Environmental impacts (inc waste products)

9. Sir Nicholas Stern predicts Climate Change will cost 5-20% of world’s GDP Whereas limits to greenhouse gas emissions just 1%

12. Cost to set up Cost to maintain Production potential Environmental negatives Environmental positives Socio- political economic positives Socio- political/ economic negatives Wind Power Nuclear Power

13. Other renewables: Hydro-power – been harnessed for centuries – Three Gorges dam etc Solar power increasingly used in the Mediterranean and USA Make sure you look into them
