What will be fueling the world in 2030
THE world will consume 40% more energy in 2030 than it does today, according
to BP's World Energy Outlook, though the rate of growth will decrease from
around 2.5% a year over the past decade to an annual rate of 1.3% in 2020-30
. One source of power has always dominated the energy mix—wood in the pre-
industrial age, coal in the industrial revolution and then oil in the 20th
century. But by 2030 trends in the energy mix will see fuel shares converge
for the first time as gas gains in importance.The amount of energy needed to
produce a unit of GDP will also converge as globalization drives energy
efficiency, making economic growth far less energy intensive everywhere in
the world. |
