LONDON, June 10 (UPI) -- Energy consumption in 2009 declined for the first time since 1982 as consumer patterns followed economic trends, British petroleum giant BP said.
An economic review of the energy sector by BP said energy consumption fell 1.1 percent in 2009, the first time in more than a decade.
The BP report said global consumption of nuclear power, oil and natural gas fell in 2009. Renewable energy use, however, increased while coal consumption remained static.
Consumption patterns, BP added, showed greenhouse gas emissions fell for the first time since 1998.
A decision by major oil producers to cut supply quotas to control crude prices meant production declines outpaced consumption.
Declines in production of natural gas from Russia, Turkmenistan and China, meanwhile, were canceled generally by robust trends in liquefied natural gas and shale gas from the United States.
Globally, there was enough proven oil reserves in 2009 to meet production for 45.7 years. Gas was sufficient for 62.8 years while there were enough coal reserves in 2009 for more than 100 years, BP said.
Iain Conn, chief executive of refining and marketing for BP, said market trends for 2010 showed consumption was again on the rise, meaning international energy companies should prepare for future growth.
"The world needs to invest today to be able to deliver the energy supplies that will be needed in the future," he said.
