Barring a Meteor strike we have about 500 million years left to enjoy the sun's energy source before it supernova. until then the sun's rays could provide the world with its greatest electrical source by the middle of the century.
A report shows solar energy could be the top source of electricity in the world by 2050, according to the International Energy Agency (IEA). Solar photovoltaic (PV) systems could generate 16 percent of the world's electricity and another 11 percent from solar thermal electricity (STE)
Solar energy will supply more electricity than fossil fuels, wind, hydro or nuclear energy sources by 2050. The shared responsibility of powering the Earth could help stabilize costs for generating electricity in the long term, according to the IEA.
The cost decrease of photovoltaic modules and systems in the last few years has opened new perspectives for using solar energy as a major source of electricity in the coming years
Achieving the 2050 prediction will depend on technology improvement and policy actions.
