subject: Nuclear and solar energy [print this page] Solar energy is becoming increasingly popular because it is sustainable, requires little maintenance and is cost-effective in the long run. Typically, solar energy is captured and converted into electricity via photovoltaic (PV) cells. There are also larger solar power plants that collect the heat from the sun, which is subsequently used to produce steam for powering a generator.
Water:
In many parts of the developing world solar energy is harnessed to pump water in remote areas. Solar energy is also used to power off-grid desalination plants.
Industry:
Solar energy has been used frequently to power TV and radio repeater stations (automated stations that transmit signals). Because it is renewable, relatively affordable, very reliable and requires little upkeep, it is also used to power lighthouses, buoys and aircraft warning lights on buildings and other structures.
Heat:
Solar energy can be used to heat residential homes; many people use solar energy to heat their water supply and, particularly in Florida, their swimming pools as well. A photovoltaic cell is installed on the roof to collect solar energy and is used to warm a heat transfer fluid that is used to heat the water itself.
Transportation:
Increasingly, solar energy is being used to power public transportation vehicles such as buses, trolleys and light-rails. Plans for solar-powered bus shelters are in the works as well.
Consumer Products:
Small gadgets that require little energy, such as calculators and watches, often use solar energy. Recreational vehicles and some boating equipment may also run on solar energy.
