SOLAR CELLS became a serious industry around 2000, when an exponential expansion in their installation began. Since then, they have gone on to make up a whopping — or rather, minuscule — 2 per cent of the global energy market.
They are, however, scheduled for continued extreme growth over the coming years, with the most dramatic predictions forecasting that their share of the energy market could increase to 50 per cent by 2050.
If it were possible to satisfy the entire world’s energy needs with solar power, (this is thought impossible because of the ways some energy must be used and stored) an area approximately the size of Spain would need to be totally covered in solar panels.
