Geologists are telling us that the oil is running out. We started to massively hike up our use of oil in the early 1900s.... and we are now going to need to massively scale down our use of oil at a similar rate.
See the graph and the (funny) video clip below. The dottted line (on the graph) labeled WEO 2006 refers to figures contained in this World Energy Outlook (click to view).
The need for our society to reduce our oil consumption is imperative in the context of Global Warming and Climate Change.... AND there is also a driving, practical need for us to reduce our oil consumption. It looks as if oil has reached its peak and the stuff is running out - meaning that the price of it is going to continue to rise very rapidly.
Compare our addiction to oil to a person's an addiction to cigarettes:
1. Like cigarettes, you might have enjoyed it, but it has certainly been very bad for you (global warming), it is also getting more and more expensive all the time... yet...
2. Unlike tobacco... we can't re-grow oil quickly... the stuff is running out... It will not run out completely... but the same quanitities of it simply won't continue to be around in order for us to keep on using it - certainly not to the extent we have grown used to using it.
