Solar energy can be used in different ways when building houses to save energy. Solar energy is a gift from nature, which makes it even more economical to use in our buildings. It is not only free, but unlike other sources of energy; it also limits the amount of pollution caused to the environment. When building our homes, the goal according to David Johnston and Scott Gibson is to create a home that uses at least fifty-two percent less energy than a conventionally built home with a corresponding reduction in costs heating and air conditioning. (Johnston, Gibson 252) This can be done through the use of solar panels, solar water systems, and photovoltaic systems. All this depends on a single source: solar energy, which is a gift of nature. Solar energy can be used to determine different things about our home. » Solar energy determines the location of our houses, the orientation towards the southern sun. , the location of the different rooms as well as the size and location of the window overhangs. » (Johnston, Gibson 250) These small factors can determine how hot our homes will be or how easy it will be to cool them. It can also determine how much light reaches our homes. “Size the south glass to capture as much sunlight as possible. Block summer sunlight with roof overhangs, shading and trees or vegetation. Choose building materials based on their mass and their potential to store solar heat in winter and keep homes cooler in summer....... (Johnston, Gibson 252) Solar water systems can be used to reduce the amount of energy used. in the production of electricity in our homes. It is commonly used in countries like Australia, Japan and China. They are usually made in such a way that they remove the middle of government paper, especially in developing countries. Governments in some countries are trying to control this problem by granting tax rebates and returns to people who install energy-saving equipment. The cost of their installations can sometimes prove to be a major disadvantage. However, the real benefit is realized over the years as electricity bills will reduce significantly. In conclusion, solar energy is used in the production of electricity in our homes. It is also used in different ways to try to minimize any energy consumption. There are both advantages and disadvantages to using this energy source, but the advantages generally outweigh the disadvantages. Solar energy should be considered as one of the energy sources that we can rely on in the future because unlike other sources it will never run out, the only thing we need to do is apply it..
