Working through the answers, we can easily answer to that question. The option A is not correct because it is obvious that the most used energy is petroleum. The option C is not correct, as well. Americans didn't use the same amount of natural gas and petroleum. They were 29% and 36%, respectively. D is not correct because Americans used petroleum to produce more power. The correct answer is B. Indeed, 10% of renewable energy makes one tenth of overall energy consumption.
