6.3.SOLAR POWER STATIONS:
Use energy from sunlight to generate electricity.There are two main types of solar power stations:solar an photovoltaic.

      1.Solar termal stations:

• Wich solar collectors that absorb sunlight in order to produce heat.
• With mirrors called heliostarts that reflect and concéntrate sunlight in one place.
  

     2.Photovoltaic stations:

• Small solar power installations can provide energy for homes and rural áreas.Excess power can be stored in batteries or accumulators and used at night.
  

6.4.BIOMASS POWER STATIONS:
In a biomass power station,the fuel used to produce energy comes from biomass.The steam produced from burning the biomass moves a turbine that is connected to a generator(alternator).
