What You Need To Know About Renewable Energy Sources
Energy is what keeps our world ticking. It cannot be destroyed nor created but can be transformed from one form to another. In Physics you probably learnt about hydroelectric power, how potential energy from the moving water is converted to electrical energy by the turbines. The sun is however the earths main power/energy source as it is used by both flora and fauna. Plants use U.V rays to make food and also solar panels generate electricity using the sun’s radiation whereas animals, like herbivores eat the plants. Energy sources are mainly classified into two parts, renewable and non-renewable energy sources.
Renewable basically means the source can be used time and time again without depletion and non-renewable means once it has been used it cannot be used again. Renewable energy sources include water, geothermal, wind and solar. Non-renewable energy sources include fossil fuel and nuclear power. Renewable energy sources are being advocated for nowadays globally as they do not damage the earth’s environment. They are green sources and are eco-friendly. Cars for example are now electrically powered a sharp contrast from the previous models which are gasoline powered. Electric cars do not produce any carbon content in the atmosphere rather they use batteries which can be charged up when they discharge.
Solar power is now used today for various uses. Solar powered laptops have even been produced which charge up the laptop’s battery. Solar powered cars are soon coming to production. Renewable energy sources are generally cheap and readily available compared to non-renewable sources like fossil fuel which has to be dug up in specific mining sites making it very expensive to mine thus the cost is passed to the consumer. Renewable energy sources are thus better to use as they are more beneficial to us and our environment and cannot be depleted.
