I want to know the answer to the following question:
According to a report in 2011, by what year could solar energy provide a third of the world's energy?
All the background I'm provided with is that "In 2011, a report by the International Energy Agency found that solar energy technologies such as photovoltaics, solar hot water and concentrated solar power could provide a third of the world’s energy by 2060 if politicians commit to limiting climate change.". Is that enough to answer the question?
