In the near future, the consumption of fossil fuels like coal, natural gas, etc. will become obsolete. People have realized that natural resources cannot be utilized for long. Very soon, we will be forced to look for alternative sources of energy. Solar energy is one of them. Scientists have stated that a small part of the Sahara desert can be used to harness enough energy to meet all the world’s power needs. If every household converts to solar energy, emissions of greenhouse gases and other pollutants will be vastly reduced.
Solar heating may become the primary energy source in the near future. In fact, it has already become popular among people. Nowadays, many new buildings are installing solar heating systems to reduce energy costs. The best thing about solar power is that it can be easily converted into other energy forms like heat, electricity, etc.
One solar product which is extremely popular these days is a Solar Water Heater. A solar water heater is made up of metal panels. As the sun rays fall on these panels, they get heated up causing the water to heat up as well. The hot water is then sent through pipes to your bathroom or kitchen. Some solar water heaters also provide filtration, thus making the water feasible for drinking.
Solar energy can also be used to light up your house with the help of photo voltaic cells. Sun rays are absorbed by Photo voltaic cells. After the solar energy is converted into electricity, it is stored in a large battery. Everyday, the photo voltaic cells are recharged by exposure to sun and then you can use the energy throughout the day.
Although it is very expensive to install a solar power unit, it is beneficial in the long term. Solar power units generally last for 25-30 years and are quite reliable. You can easily recover your costs within 2-3 years of installation. Using solar energy will help us reduce our dependence on natural resources that are fast becoming depleted and make our planet a much better place to live in.
