Solar Energy it is Energy from the Sun Solar Energy Can Be Used
for Heat and Electricity Solar thermal energy: There are many
applications for the direct use of solar thermal energy, space
heating and cooling, water heating, crop drying and solar
cooking. It is a technology which is well understood and widely
used in many countries throughout the world. Most solar thermal
technologies have been in existence in one form or another for
centuries and have a well established manufacturing base in most
sun-rich developed countries. The most common use for solar
thermal technology is for domestic water heating. Annual

Heater There are two basic types of solar thermal power station.
The first is the 'Power Tower' design which uses thousands of
sun-tracking reflectors or heliostats to direct and concentrate
solar radiation onto a boiler located atop a tower. The
temperature in the boiler rises to 500 - 700EC and the steam
raised can be used to drive a turbine
