Ratings agency Standard & Poor has said that the renewable energy market shows a promising future for solar and wind technology.
In fact, the oil and gas giant Shell forecasts that solar could become the world’s largest primary source of energy by 2070.
Take for example, Germany, which now has a cumulative capacity of 32.6 gigawatts, and will see its solar energy market become sustainable by 2014.
Other countries including India, China, and Mexico are increasing their solar energy markets.
“Worldwide, the 2012 investment total in clean energy was the second highest ever, and five times that of 2004.”
