What is solar energy?

Solar power is a booming renewable energyIt could account for 16% of worldwide electricity production in 2050, compared with 3.7% of today’s energy mix. But it has a bright future because the sun’s energy is eternal (five billion years’ life according to astronomers). In fact, of all renewable energy sources, solar power is the fastest growing. Its price has become very competitive in a growing number of countries. And solar energy is set to become a vital source if our world is to be carbon neutral by 2050.  What is solar energy?It is the energy generated by solar radiation. The nuclear fusion that occurs on a massive scale in the Sun releases incredible quantities of heat and light. We humans capture part of the energy received on Earth to produce electricity and heat. Two key technologies help us do this: photovoltaic solar panels (electricity production) and thermal solar…
