What is the energy problem

The energy problem is analysed: energy supply must be made to match demand, but demand can change quite rapidly and flexibility is important. Energy storage is discussed. Energy resources are examined under the following heads: oil, natural gas, coal, uranium, renewable resources, oil shale and tar sands. Energy demand is discussed for the non-communist world, covering economic aspects, conservation and the use of other energy sources to supplement oil (showing the costs of these other sources compared with oil).
