Energy stored in fossil fuels is the radiation that these plants and organisms once received from the sun. Sun actually delivers the Earth an enormous amount of energy every hour. This energy is then distributed everywhere on the planet parts which are exposed to it (daylight). When we gather all of this energy that the Earth receives from the sun just in 1 hour, it will exceed all the energy we consume collectively on the entire planet in a year.
Just imagine – one hour of sunlight gives us as much energy as all of the humanity needs for an entire year! Yet, the benefits of this clean energy are not utilized in full. On top of almost zero carbon footprint of solar energy, it’s virtually non-depletable, as the sun is expected to shine for around 5 billion years longer!
