Combined energy systems
a briefing document
energy systems is a sub-document
to Distributed energy systems
and micro-generation, and part
of a series of briefing documents on the problems of power
consumption, posed by the steady depletion of fossil fuels
and most particularly of pumpable oil.
One of a grouping of documents on global concerns at abelard.org.

Much of the future of energy will be mixed methods, not a matter of one mighty leap. Thus, society will rely on wind, geothermal, sun using both photovoltaics and non-pv solar technology, biofuels and nuclear power.
Looks impressive? Keep cool, the whole world production claimed above is probably worth less than one standard big power station in European conditions. However, the rapid growth and improving technology are much to be welcomed.
A video giving a very useful (but unrealistic) description of combining various energy production methods.
From p.27 of Key world energy statistics from the IEA, recently [December, 2007] issued by the International Energy Agency:
As you can see, Germany is already the prime electricity importer in the world, whereas France is the premier electricity exporter.
Referring back to the video above, the dogmatic anti-nuclear stance taken in Germany is ludicrous.
The claims of their no-nuclear energy experiment are nonsense. Germany claims that one hundred percent of their energy needs will be produced using renewables by 2050 (40% by 2020). This claim applies only to electricity supply at current levels. It has no allowance for heating and transport, nor any allowance for growing vehicle electrification.
Meanwhile, the German car industry is whining up a storm at changing controls of their home gas guzzler production. There is no consideration of the vast amounts of bio-fuel sources required. There is no consideration of the huge cost of pumped water energy storage.
The German proposals are all very neat in theory on a small scale, but not convincing in the real world.
