Green shacks have many benefits. Because they are designed to be affordable and useful, they don’t have any complicate systems. In fact, they don’t have a power outlet, so using electronic gadgets is impossible. Actually, you can have electricity in a green shack, but you will have to add certain systems. Of course, all systems you can add cost, and you cannot make them alone, but they will make your life better.
The first and the most important system you can add is solar panels. You can install them on a roof, and they will harvest energy from the sun. They are affordable, if you buy smaller panels. But this system will give you an opportunity to charge batteries on electric devices and you will have illumination of a green shack. Also, if you live in the area where sunlight is strong, you will have more than you need of electricity.
The second improvement is wind generator. Basically, it has the same purpose as solar panels. If you like in the area where there is no enough of sunlight, but you have a lot of wind, this is the better choice for you. Also, they are easier to install than solar panels. You can use them, together with solar panels, but only if you need a lot of electricity.
Rainwater collection system can be used if you have a vertical garden. Also, it can be used only in areas where rain is common. If you live in the area where there is no enough of rain, you don’t need this system. In general, they can collect enough water for a vertical garden.
