By the year 2020 the globally available solar energy uses will grow by 20 % to 40%. And you should note that the project is still in infancy. Not many part of the world uses solar energy in large quantity. I do feel that you will definitely find the solar energy being used in large quantity in the coming future. You can argue that the solar energy is a little bit expensive. Most of us think of the expensive solar panels. The whole system can cost your around $30000 and you can say that this is a huge amount to invest. However I do feel that the solar energy generation on large quantity is expensive still but you can hope for much cheaper rates in coming future.

One of the people from San Diego has following points to say about the usage of the solar energy. His current cost for 600 KWH per months costs $101 and gas for his car cost around $ 180. Hence in total he used to spend $281 every month. At $ 0.25 KWH/mile and 1500 miles per month he would require 375 kW of electricity combined with the 600 KWH for the home. In total it mounts up to $975 solar power. He determined that he would require 8 WATT solar system for a San Diego location. The installed cost was around $55000. He got the rebate of $ 17000. Hence in total he was charged around $38000.

He decided to take the home equity loan at 6.5 % rate which cost him only $239 a month and he was able to save $40 per month. With all these calculation you can come to only one conclusion and that is the solar energy system can still be economical if you plan it well. You can produce the total required energy at economical cost.

However there is also one more side of this discussion and that is you can save the electricity as well. For example it is the habit of most of us to use the lights even in the day time. I really feel that you should open your windows and use the sunlight instead. If you are running the AC then also you can make some proper arrangements so that the right amount of sun light enters your room. You can use the sky lighting system as well. The periscope technology can also be used.

Apart from all this you can also use the solar heater instead of greaser. This will definitely save lots of electricity. What this will do is simple to understand. You will be able to lower your electricity usage and hence your solar panel will cost less. Hence solar energy system can be economical if well planned.
