These are the top three disadvantages of the otherwise excellent program "Earth 4 Energy." Yes, you can definitely make a solar or wind powered system to make you free electricity. The question, however, is whether you can accept the three disadvantages mentioned below:

Disadvantage 1: Solar and wind power harvesting capabilities fluctuate with changing natural conditions

You can make a lot of electricity from solar and wind power. However, in the first case you need strong sunshine and clear skies. In the second case you need good and stable wind. However, such perfect conditions are rather rare even in the best areas. For example, in the place I am living, it is often sunny and there is a mild breeze, which might give many people the idea that it would be a good idea to build a solar or wind power system. However, the last few days have been cloudy mixed with a little bit of rain and the wind has been rather weak. In days like these, almost no electricity can be made, so the owner of the system is stuck with being unable to use his system, in which he has invested so much time and money.

Disadvantage 2: A good and efficient renewable energy installation is not easily built by just anyone

Do It Yourself guides, such as "Earth 4 Energy," claim that a solar or wind power system can be built by anyone with the proper training and guidance. In fact, virtually anything can be done with the proper time and effort allocated to it, but is the investment in time and energy really worth it? "Earth 4 Energy" boasts some of the best guided training on the market for DIY renewable energy installation construction kits with detailed instruction both in pictures and videos. However, even that would not be sufficient for someone who is not technologically and electronically knowledgeable. Therefore, one needs to know whether they are willing to work hard at this otherwise easy to make project before purchasing the guide.

Disadvantage 3: There are so many renewable energy installation DIY guides on the market that it is hard to choose the best one

Indeed, users in the renewable energy installation DIY field are spoiled by the choices that are available to them. Should one go for "Earth 4 Energy?" Or is not "Home Made Energy" better? And how about the other programs that abound on the Internet? Sometimes it is really hard to decide without trying the program for yourself. Well, I myself did, and I must say that "Earth 4 Energy" was perhaps the best choice for me. But that is only my opinion. You should definitely make your own mind by reading reviews of other products and comparing them for a while before making a definitive decision.

These were the top 3 disadvantages of "Earth 4 Energy" - the famous system to generate free electricity through solar and wind power. While this article did not mean to discourage you from purchasing this system, it definitely aimed at leaving you more educated as to this system than you were before reading it. In the end, "Earth 4 Energy" definitely deserves a shot, but so do other programs available on the market. Therefore, the best option would be to compare your options by reading more reviews of these programs.
