Advantages and Disadvantages of SOLAR ENERGY

Written by Anita van Wyk


Many of us know that solar energy is good, but few really understand why.

Therefore, I compiled a comprehensive list of solar energy advantages and disadvantages that will enable you to make an educated decision whether on not Solar Power is right for YOU. Solar Energy Advantages

1. Saves you money

  • Afterrepparttar initial investment has been recovered,repparttar 150139 energy fromrepparttar 150140 sun is practically FREE.
  • The recovery/ payback period for this investment can be very short depending on how much electricity your household uses.
  • Financial incentives are available formrepparttar 150141 government that will reduce your cost.
  • If your system produce more energy than you use, your utility company can buy it from you, building up a credit on your account! This is called net metering.
  • It will save you money on your electricity bill if you have one at all.
  • Solar energy does not require any fuel.
  • It's not affected byrepparttar 150142 supply and demand of fuel and is therefore not subjected torepparttar 150143 ever-increasing price of gasoline.
  • The savings are immediate and for many years to come.
  • The use of solar energy indirectly reduces health costs.

2. Environmentally friendly

  • Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment.
  • It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury intorepparttar 150144 atmosphere like many traditional forms of electrical generations does.
  • Therefore Solar Energy does not contribute to global warming, acid rain or smog.
  • It actively contributes torepparttar 150145 decrease of harmful green house gas emissions.
  • It's generated where it is needed.
  • By not using any fuel, Solar Energy does not contribute torepparttar 150146 cost and problems ofrepparttar 150147 recovery and transportation of fuel orrepparttar 150148 storage of radioactive waste.

3. Independent/ semi-independent

  • Solar Energy can be utilized to offset utility-supplied energy consumption. It does not only reduce your electricity bill, but will also continue to supply your home/ business with electricity inrepparttar 150149 event of a power outage.
  • A Solar Energy system can operate entirely independent, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations (like holiday log cabins), making it more practical and cost-effective thanrepparttar 150150 supply of utility electricity to a new site.
  • The use of Solar Energy reduces our dependence on foreign and/or centralized sources of energy, influenced by natural disasters or international events and so contributes to a sustainable future.
  • Solar Energy supports local job and wealth creation, fuelling local economies.


Employ passive solar energy and start saving electricity today.

Here are 7 basic fundamentals that will cost you nothing or very little and save you cash for many years to come!

1. Orientation, layout and positioning of your house onrepparttar land

Orientate your living areas torepparttar 150138 south side ofrepparttar 150139 house, which receives most ofrepparttar 150140 sun throughoutrepparttar 150141 day (north if you live inrepparttar 150142 southern hemisphere).

2. Insulation and draught proofing

Make sure your walls, roof and floors are insulated and fill any gaps where draughts might come through.

3. Ventilation

Position doors and windows opposite each other to allow for a cooling breeze to flow throughrepparttar 150143 house whenrepparttar 150144 air cool down inrepparttar 150145 evening of a hot summers day.

4. Windows

Windows onrepparttar 150146 south side ofrepparttar 150147 house should be bigger to allow more sun to penetraterepparttar 150148 house duringrepparttar 150149 day and windows onrepparttar 150150 north side smaller to prevent heat lost at night.

5. Landscaping

Position trees and plants to direct a cooling breeze into your house, whiles shading it during summer. Plant trees that shed their leave in winter.

6. Shading

Make sure external shading structures are wide enough to block outrepparttar 150151 sun in summer, whiles still allowingrepparttar 150152 low winter sun to enter.

7. Thermal mass

Polished concrete, tile or slate floors and brick walls will absorbrepparttar 150153 heat throughoutrepparttar 150154 day and release it slowly at night, reducingrepparttar 150155 need to run expensive heaters. Carpet acts as an insulator and will not retainrepparttar 150156 heat.

Although itís far easier to achieve passive solar energy for homes duringrepparttar 150157 planning stage, you can incorporate many of these elements into an established house without spending a great deal of money or time.

It might be as easy as filling in a few gaps, installing an additional window or moving your living area fromrepparttar 150158 chilly north side ofrepparttar 150159 house torepparttar 150160 sunny south side...
