According to the BP report to world energy supply and demand investigation in 2016, the growth of world energy consumption was still around 1% for 3 years from 2014, and was turned to lower carbon energy. For petroleum, the explored reserves, production and consumption were slightly increased. For natural gas, the explored reserves and production slightly increased, while the consumption growth slowed down. However, pipeline gas and liquefied natural gas trade volume increased rapidly. For coal, the reserve was rich, while the production and consumption declined continuously. Other energy, such as nuclear, water, wind, sun, biofuels, etc., develop faster than traditional fossil fuels. The energy structure adjustment and economic growth slowdown contributed to the slow growth of the world's carbon emissions. To 2035, it is predicted that energy demand of the whole world would grow at an annual rate of 1.3%, mainly from emerging economies. Natural gas consumption growth will be higher than coal and petroleum. And the petroleum will still be the world's leading fuel, but coal demand will peak in 2025. Nuclear power, hydropower and renewable energy in the primary energy are expected to rise from 15% to 23%.
