1) In the end of 2017, Google announced that the company will expand its renewable energy use by buying wind-generated electricity from 3 states.  The company said it will buy 200 megawatts (MW) of wind power from Iowa, 196MW from South Dakota, and 140MW from Oklahoma.  How much of wind power will Google buy from those three states?

2) Google is the largest buyer of renewable energy and bought 2,397 MW of renewable energy in the United States. The second-largest buyer of renewable energy is Amazon, which bought 1,219 MW of renewable energy. How much more renewable energy did Google buy than Amazon did?
