MIT comes to the conclusion that with existing solar panel technology, the world can very well be powered. The real bottleneck is not technology, but investment. By 2050 a large chunk of the current overall power consumption of 15 terawatts could be replaced using solar power. 15 terawatts represents the power equivalent of 15,000 standard 1 GW power plants.
MIT expects battery technology to play a key role in the development of the solar economy.
