I want to know the answer to the following question:
Hydroelectricity accounts for what percentage of global electricity generation?
All the background I'm provided with is that "It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010, and is expected to increase about 3.1% each year for the next 25 years.". Is that enough to answer the question?
Answer: no
