A shroud of uncertainty hangs over world energy markets and industry due to the effects of the global downturn and an aggressive U.S. environmental agenda, making investment decisions in the space more difficult than they’ve been in decades.

Oil prices, which have whipsawed between $150 and $30 a barrel in a matter of months, are in the midst of a rebound tied to hopes that the recession will end sooner rather than later, reviving world energy demand that has been shrinking for the first time in a quarter century.

Meanwhile, the Obama administration has been pushing forward aggressively with climate, alternative energy and efficiency proposals that could change the economic equation considerably for the world’s oil producers, refiners, utilities, and of course alternative energy producers.

What is the outlook for world energy demand and prices? How will OPEC adjust its output policy to navigate the uncertainty? What big energy projects will go ahead and which ones will wither? How will the landscape impact mergers and acquisitions activity? What are the best opportunities in the green energy space, and what are the biggest risks?

The upcoming Reuters Global Energy Summit will bring you exclusive answers to these questions from some of the sector’s biggest names. The Summit will generate exclusive stories, online videos, blogs and investable insights which will be immediately available only to Thomson Reuters clients during each summit.
