China's energy mix differs sharply from that of most Western countries. What fuel dominates China's commercial energy consumption, and what change occurred in 2009 involving China's emissions?
ANatural gas dominates, emissions fell below Japan's in 2009
BCoal is two thirds of China's use, passing the U.S. in CO2 by 2009
COil dominates, emissions have stayed unchanged since 2009
DNuclear dominates, China dropped coal entirely by 2009
Answer & Solution
Correct answer: B. Coal is two thirds of China's use, passing the U.S. in CO2 by 2009
1. Unlike most Western countries, China's commercial energy resources are dominated by coal, which accounts for two thirds of its energy consumption.
2. In 2009, China surpassed the United States to become the largest generator of carbon dioxide in the world.
3. Natural gas, oil, and nuclear power are each part of China's energy mix, but none of them is described as the dominant two-thirds fuel that coal is.
4. China did not eliminate coal use or leave its emissions unchanged, since the 2009 milestone specifically marks a rise to the top position in CO2 generation.
