Solar Energy

Solar energy is also a form of renewable energy that has became more popular over the past few years. Solar energy captures the sunlight and converts it into electricity. Solar products are also being incorporated in many of our house hold products. These products include:
  • outdoor solar lights
  • calculators
  • cell phone chargers
  • car chargers
Advantages
  • Inexhaustible fuel source
  • No pollution
  • Often an excellent supplement to other renewable sources
  • Versatile--is used for powering items as diverse as solar cars and satellites
Disadvantages
  • Very diffuse source means low energy production--large numbers of solar panels (and thus large land areas) are required to produce useful amounts of heat or electricity
  • Only areas of the world with lots of sunlight are suitable for solar power generation

Bio Wave technology is an area that is currently being research. These buoy's are submerged under water and the currents of the ocean sway them back and forth. The motions are being converted into electrical energy.
