Another use of thermal solar energy is to cook food in portable solar ovens, which typically concentrate solar energy from the sun gathered across a wide area to a central point, where a black-surfaced vessel converts the sunlight into heat. Advantages. Solar energy has a number of inherent advantages:
The energy from the Sun - both heat and light energy - originates from a nuclear fusion process that is occurring inside the core of the Sun.The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion.. Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together
Not all of the sunlight that strikes the top of the atmosphere is converted into energy at the surface of the Earth.
