In last 30 years, the consumption of energy doubled. The accelerating increase in energy consumption makes the prospect of exhausting fossil fuel resources even more imminent. Therefore, we should switch to renewable energy sources such as wind, hydropower, and geothermal energy. Solar energy is the easiest and the least expensive to harvest. Special facilities for catching and storing solar energy are simple in terms of design and they do not need sophisticated parts and expensive components. The author describes in detail how such a facility could be built at home.
