China is Worldâs Largest Energy Consumer. World consumption of energy has increased 5.6 percent in 2010, according to BPâs Statistical Review of World Energy. This is the largest increase since 1973, which happened to be a memorable year in energy history.
The International Energy Agency projected in 2014 that under its high renewables scenario, by 2050, solar photovoltaics and concentrated solar power would contribute about 16 and 11 percent, respectively, of the worldwide electricity consumption, and solar would be the world's largest source of electricity.
