The Main Role of Electricity in Our World

Electricity plays a main role in our world. It's important to know how electricity works and how electricity is created. Electricity could either be made by renewable and non-renewable source. Renewable can be created by itself and non-renewable can't recreate by itself. A non-renewable source requires fossil fuels while renewable does not. My renewable source is solar power and for non-renewable fossil fuel is coal.

Solar power is a renewable alternative energy. The sun helps the solar power to produce energy and converted to electricity. The sun provides the earth with two major forms of energy, heat and light. There are three ways types of solar power solar cells, solar water heating and solar furnaces, but the most common solar power is solar is solar cells. How solar cells works is when there is a sunny climate the sun reflects in to the solar power so that it can get electricity. Most solar power systems utilize heat energy for heating will the others transform light into electricity. Solar Power is not only for house use but also for cars. Now in days, vehicles run on with solar power. According to (makeitsolar.com), it says, “PV panels as a direct power source that convert light energy into electricity to power their motors. When sun is not available, cars will not run, so, is better to have a car powered by batteries that can recharged with solar energy” describes how solar power is the better way to save electricity and could easily recharged when sun is available at no cost. Solar power is the better way to save electricity without using house power or car battery.

Coal is a fossil fuel that can be use to create electricity. In order for coal to create electricity it requires mining, transport of power plants...
