Question

global annual solar energy capacity
based on this graph, you can predict that by 2016, solar power plants will be able to generate
less than 60 gigawatts of energy.
about 80 gigawatts of energy.
about 100 gigawatts of energy.
more than 120 gigawatts of energy.

Explanation:

1. Observe the graph's trend: from 2008 (≈15 gigawatts) to 2012 (≈100 gigawatts), capacity grows rapidly.
2. Extend this sharp upward trend to 2016 (4 years after 2012). The 2012 value is already near 100 gigawatts, so the 2016 value will exceed this.
3. Match this prediction to the given options.

Answer:

about 100 gigawatts of energy.
