The Earth4Energy manual is a great step-by-step guide for anyone wanting to build their own solar or wind power generator. The decision to use solar or wind power for an alternative energy source is not only great for the environment, it’s also very good for your wallet. Let me explain.

The first homemade solar panel I built was a portable solar power system for just under $200. You know, when I started building renewable energy sources I did it because of curiosity. I had heard that many people managed to create energy-generating devices, so I thought I will manage to do them to. When I found information about earth4energy and its videos I had no doubts that this is what I need.

The guide contains so many different solar panels blueprint, personally I used only portable solar panel, however if you want for example a grid-intertied panel you will find how to build it there. You know, the most powerful setup is undoubtedly an off-grid setup, it can generate electricity fo your entire house and sometimes even give electricity to your neighbours. But what about the price of the materials?

Believe it or not, but if you have enough materials in your household, you will spend $0 to build a solar panel. Some of the required materials are very easy-to-find, moreover, we use some of them every week.

The whole guide is not only about building solar panels, it will also show you how to build wind turbines. Believe it or not, but a small turbine could cost less than one hundred dollars, you know, they are ten times as expensive in shops. However, the problem is that it is impossible to generate electricity if you do not have enough wind in your country. A basic rule is that you want the average wind speed in the area to be around 10mph for the unit to be cost effective.

If you really want to build a wind turbine or a solar panel to generate electricity, earth4energy is undoubtedly what you need. How do windmills work
