Energy Sources

If I were to build a house that I wanted to live in forever, I would use the energy resource of solar. I would do that because even though it is expensive at first, it pays off in the end. Solar energy is free to get and there is an abundant supply of it. However, one of its disadvantages is that the sun is not always showing. So, to solve this problem I would store the energy I have not used yet and use it on days when the sun is not out.
