The Age is about to change.

 Summary:

The Olduvai Theory is defined as the ratio of world energy production and population. It states that average energy production per capita will decline to its 1930 level by 2030. Collapse will be strongly correlated with an “epidemic” of blackouts around the globe. This warning has come from scientists for more than a century, but it is still disallowed in Washington, D.C. A back-to-the-land movement has emerged and is accelerating.1
