It seems the Chinese are more than just talk. The Chinese Government made a big thing about Earth Hour a few days ago, but before that they were already planning on moving into green renewable power as a source for their growing industrial power needs.

In the year 2010, China plans to bring online a 1.5 megawatt solar thermal power station.  This will be capable of supplying the power needs of over 30,000 homes.  The cost of this plant is to be approximately 100 million yuan.  The power plants will cover an area of approximately 13 hectares.  The funding for this project is from the Ministry of Science, the city of Beijing and the China Academy of Science.

The power output of this new plant is expected to be in the range of 2.7 million kWh of electricity per year.  Since a conventional coal burning plant would produce 2,300 tons of CO2 emissions for the same power generation, this will help reduce the pollution problem plagued by Beijing.

The heart of the plant will be a solar tower that is to be 100 meters tall and contain 100 heliostats of curved mirrors that will follow the sun and direct the rays to a receiver at the base of the tower. There the rays will be transformed to thermal power and the steam generated will directly run the turbine for electrical generation.

Thermal power stations have to be larger than a solar photovoltaic stations but because of the scale the energy is cheaper. In Spain there are both types of solar power plants producing electricity.  The photovoltaic plant is 44-euro cents per kWh while that of solar thermal power station is only 27-euro cents per kWh.

This is a cheap renewable energy power source. The more that is invested in the future the greener our world will be. Look into solar thermal power and invest in a greener tomorrow.
