The worldwide campaign to encourage 100 per cent renewable energy usage by businesses is resulting in an increasing number of Silicon Valley big players to invest in wind and solar power.

Facebook announced earlier this year that they would soon be offering internet connectivity to over 5 billion people who do not currently have access. The global giant plans on achieving this astonishing feat through the use of a solar drone which is scheduled to be tested within the coming summer.

Connecting to Facebook via a solar powered plane may no longer be a far-fetched prospect. The company is reportedly in talks to buy Titan Aerospace, a company that manufactures solar powered drones that can fly 5 years without the need to land.
