Solar Energy (Pros & Cons)

  • Renewable Solar energy is renewable energy at its best, meaning that however much of it is used it will never run out. Non-renewable energy is running low and will run out.
  • Abundant The Earth’s solar energy potential is almost infinite with an estimated 20,000 times more power capacity than we will ever likely need.
  • Sustainable This is an important term in the world today when applied to solar energy because it means what energy we are getting from the sun, the same amount will be there for the next generation.
  • Expensive In the early days of development solar power was expensive to tap but these days it is a lot more attractive and cost effective.
  • Irregular Supply Solar energy is not there 24 hours a day and no one can predict its availability exactly. In other words it’s not always there when we want it. However we do know that we can’t run out of it.
  • Requires Space Solar energy is a renewable energy source. This means that we cannot run out of solar energy, as opposed to non-renewable energy sources


Solar energy is clean, it’s abundant and its renewable energy and the U.S. have plentiful supplies of it. With current technology there are several ways available to tap this energy for both light and heat and for private and commercial use;

3 simple ways to harness solar energy:

1. Photovoltaic (PV), which converts the sun’s light to electricity directly...

2. Concentrating solar power (CSP), or thermal energy which uses the sun’s heat to provide energy to electric turbines which is dispersed to consumers.

3. Cooling and Heating systems, which use thermal energy to provide air conditioning and hot water.

Solar energy is distributed generation (DG), which means solar installations such as solar panels are fitted on roofs or in large groups at ground level near to the supply point for electricity. More advanced installations feed a central power facility which provides electricity across a wide area.
