Water heating and disinfection
Solar energy is used to heat water through a solar heater, which is a cleaner method and less expensive to operate than the stoves that were used for this purpose, which relied on burning wood or coal. Despite the decline in the cost of oil and natural gas in the early twentieth century, some countries resorted to To replace solar water heaters with them, some other countries, such as Australia and Spain, still require their use in any new construction. In addition, approximately 28 developing countries exploit solar energy to purify water to make it suitable for drinking on a daily basis, by filling water in Plastic bottles and then expose them to sunlight for several hours.
Electricity generation
Many factories exploit the heat of the sun to generate electrical energy as it is an abundant source of renewable energy. This process is based on the use of mirrors that track the sun and reflect its rays to a central point at the top of a tower containing tubes containing a liquid that absorbs the heat. This liquid is then pumped when it becomes hot into the A generator converts it into steam, and this resulting steam drives a turbine responsible for generating electricity.
Heating homes
Solar energy can be relied upon to heat rooms and homes, and this can be explained through the (solar room) model. In this model, the glass room allows sunlight to pass into it during the day through the feature of transparent glass that collects these rays. To obtain heating for the room, and to continue to obtain heating in the period after sunset, it is possible to add plants and rocks in the room as a type of decoration, as these rocks will be useful because they will work to store heat and then benefit from it after sunset.
