Solar-thermal power touted as energy solution. 31/03/2006. ABC News Online

Australian scientists have developed a new form of electricity that could provide all of Australia's electricity needs in 2020.

It has been developed by mixing solar energy, heat and natural gas.

In the search to find a cleaner, more efficient form of power, scientists at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) have developed what is called solar-thermal energy.

Two hundred mirrors track the sun, and focus the sun's rays towards a tower.

The heat can reach temperatures of more than 1000 degrees Celsius, producing 500 kilowatts of power.

This is then mixed with natural gas and water to produce a renewable energy.

Wes Stein from the CSIRO says the new development could provide for Australia's future energy needs.

"It would only require about 50 kilometres by 50 kilometres in the centre of Australia somewhere to provide all of Australia's electricity needs in 2020," he said.

"That's not very much of Australia."
