This web site is intended to give simple but, I hope, accurate information about many sources of energy, together with their connection with population, population growth and Global Warming.  Although the emphasis is on newer types of energy, especially renewable ones, I intend to include more traditional energy sources as well.

Apart from the actual energy information I am including some of my own opinions like the likely effect of changing to renewable energy on Jobs and the Economy, the lack of long term planning by our governments and a consideration of whether we can have Prosperity Without Growth, and suggested National Goals.

Solar Energy is becoming more popular.  There are two basic types, Solar Thermal and Photo Voltaic.

Algae is a Potential source of Energy and of transport fuels like Oil and Ethanol.  It could also be used directly as a fuel in power stations as described in An Algae Fuelled Power Station.

Nuclear Power is one that many people talk about.  There are several possible different forms including Uranium Fission, Thorium Fission, Magnetic Containment Fusion, Inertial Confinement Fusion, Cold Fusion and Focus Fusion.

Power can be obtained by the mixing of fresh and saltwater.  This is referred to here as Osmosis.  The processes are explained in Pressure Retarded Osmosis and Reverse Electrodialysis.

Geothermal Power is already providing useful amounts of electricity in a few places.  It has great potential.  The two main types are Volcanic Geothermal Power and Hot Rock Geothermal Power.

Naturally, Fossil Fuels are used extensively and will continue to be used.  These include Coal, Oil, Natural Gas, Coal Bed Methane and Methane Hydrates.
