1. Geothermal power from Iceland
In April 2007, the Icelandic National Energy Authority signed a deal with Energie Baden-Wuerttemberg from Germany, to work on electricity being transmitted to Germany from Iceland. A 1,200-mile ocean-floor cable is envisaged to carry electricity to Britain’s national grid before reaching Germany. The proposal is to drill 3.8km through the Earth's crust into the hot basalt below, in order to tap into temperatures of up to 600C and generate enough geothermal electricity to power up to 1.5 million homes in Europe.

2. Hydropower from Congo
The Grand Inga power station is a project to harness hydropower of the Congo River. Located near the mouth of the Congo River, with an output of 39,000 megawatts, Grand Inga would be the world's biggest hydroelectric scheme, generating twice the power of China's Three Gorges dam.
Three electricity superhighways would deliver power south to Angola, Botswana and South Africa, west towards Nigeria and north to Egypt and - ultimately - southern Europe. The project might cost $US80billion, but power delivered from Grand Inga to the Italian border would cost less than the current market price of electricity in Italy today.

3. Thermal solar power from Africa
The Trans-Mediterranean Renewable Energy Cooperation (TREC) was founded in September 2003. One proposal is for Thermal Solar Power to be generated in the deserts of Africa, for transmission by means of High-Voltage Direct Current cables to Europe, with losses of only about 3% per 1000 km, adding up to losses across the Mediterranean of 10-15% to Europe.
