IEA发布的世界能源展望2009英文全版
World Energy Outlook 2009
Since WEO-2008, the economic downturn has led to a drop
in energy use, CO2 emissions and energy investment. Is this an
opportunity to arrest climate change or a threat that any economic
upturn might be stifled at birth 
What package of commitments and measures should the climate
negotiators at the UN Climate Change Conference (COP 15) in
Copenhagen put together if they really want to stop global
temperatures rising  How much would it cost  And how much might
the developed world have to pay to finance action elsewhere 
How big is the gas resource base and what is the typical pattern
of production from a gas field  What does the unconventional gas
boom in the United States mean for the rest of the world  Are we
headed for a global gas glut  What role will gas play in the future
energy mix  And how might the way gas is priced change 
All these questions and many others are answered in WEO-2009.
The data are extensive, the projections more detailed than ever
and the analyses compelling.
