altEnergy1. As the market of alternative power sources grows, there are now two most cost-effective and therefore popular products – Wind power plants and Solar power plants.
Let us explain the basics of these two energy sources, as well as the pros and the cons. Wind power plants literally harness the power of the wind to propel the blades of wind turbines. The turbine’s rotation is then converted to electricity via an electrical generator. The process was mechanical before, then there were single wing towers with mini generators. Today electricity is produced by large wind farms used not only by national electrical grids but is also harnessed by small individual turbines to provide electricity to individual homes or isolated areas.

Pros

  • No pollution
  • No harmful by-products of production
  • Renewable
  • The land occupied by the wind turbines can still be used for farming and grazing
  • Off-shore wind farms

Cons

  • It is intermittent.
  • Negative effect of the large scale wind farms on the scenery

2.Now we can proceed to solar power plants. Solar power harnesses heat by trapping the sun’s rays into solar cells where it is then transformed into electricity. There are several methods of harnessing the power from the sunlight. Sunlight that hits solar thermal panels is used either to heat water or air. Different methods include using parabolic mirrors to heat water (producing steam). These power plants can be modified to individual needs of every consumer – big corporate solar energy power stations, small private, isolated power stations. It’s the cheapest alternative for private usage.

Pros

  • No pollution
  • No harmful by-products of production
  • Renewable
  • Can be used very efficiently for heating and lighting.
  • Often is the best solution to heat pools, spas, and water tanks.

Cons

  • It is intermittent.
  • Nighttime and cloudy days seriously limit the amount of energy produced.
  • Large scale solar power stations can be expensive.
