While Tesla Inc (NASDAQ: TSLA) founder Elon Musk continues to hog the news headlines, there is no doubt that the renewable energy sector is growing in massive leaps and is much bigger than Musk’s high-profile personality.

US $777.6 billion.

That is the projected amount of revenue to be generated from renewable energy sources by 2019 according to Research and Markets, one of the leading market research companies in the world.

While that may seem a massive amount (and it is), that estimate is backed by major energy research bodies around the world. And it is based on previous year’s data which shows that in 2013, the renewable energy market totalled US$ 432.7 billion. The compound annual growth rate is expected at about 10.3 percent, which is a healthy growth rate from whichever angle you look at.
