Production from Giant Gas Fields in Norway and Russia and Subsequent Implications for European Energy Security

from Global Energy Systems website. Here is another rigorous study (abstract) documenting that peak energy is here. In this case it's natural gas.

The International Energy Agency (IEA) expects total natural gas output in the EU to decrease from 216 billion cubic meters per year (bcm/year) in 2006 to 90 bcm/year in 2030. For the same period, EU demand for natural gas is forecast to increase rapidly.
