Solar energy is the clean and ultimate form of energy included in renewable energy which once we used in our daily life purposes, can,t harmful for human health because the radiation comes from the sun towards the earth's surface absorbed by the solar plates also called solar panels mostly made up with germanium element. the solar cooker is the most attractive technology that moves us towards sustainable development. There are many benefits of solar energy in nowadays, the most common advantage is the generation of electricity by the conversion of solar radiation (heat) into electrical energy and another benefit of solar energy is the direct use of solar energy i.e photosynthesis in the plants so we get food because solar energy converted into chemical energy in the leaves of plants and then human being use this energy in the form of food so we can say that the solar energy can be converted into mechanical energy when we perform any activity after eating food.
