SOLAR ENERGY (BY AMIR LALE)

Solar energy is the energy from the Sun’s radiation. Fossil fuels, like coal, gas, and oil, are produced by sunlight through photosynthesis over millions of years. Moreover, using fossil fuels can also cause pollution. Although the formation of fossil fuels depends on sunlight, solar energy comes directly from the sun. The lifetime of the Sun is quite long that there is no worry about running out of solar energy.

Solar energy exists for a long period of time. It has been used by humans for thousands of years. There are two main ways to use solar energy which are passive solar energy and active solar energy. Passive solar energy can be allowing sunlight through windows to heat a place while Conversion of sunlight to electricity is a form of active solar energy.

As we know, most of the electricity supplies in our houses are produced by burning fossil fuels which have been creating a massive and negative impact on the environment. Therefore, using Solar energy should be our main source of electricity which is neutral in its effect on the ecosystem.

The main tool to use solar energy is the solar panel which is installed on the roof of the house, which captures and reserves solar energy on batteries. Before installing, we should consider the available solar resource for your home and the size of the roof to see whether it is able to install the solar cell. Sometimes the solar panels will generate more energy than a household actually needs. But some solar panels have an advantage of storing the excess energy which can be used later.

The advantages of solar energy are the fact it is environmental-friendly energy; it also can help people to save money and is easy to be established in a house. The disadvantages can be the high initial cost to install it and it is climate and water selective.

To conclude, solar energy has a lot of benefits and especially the fact that it will not produce any harmful and toxic substances as other electricity sources makes it more suitable to combat current ecological destructions we are encountering in the world. Hopefully In the near future, electricity which generated by the solar energy stabilizes more and can fulfill household daily demand.
