I want to know the answer to the following question:
How much was the worldwide investment in solar power in 2012?
All the background I'm provided with is that "Worldwide investment in solar power in 2012 was $140.4 billion, an 11 percent decline from 2011, and wind power investment was down 10.1 percent, to $80.3 billion.". Is that enough to answer the question?
Answer: yes
