I specialize in information about lifeboats for Peak Oil. I guesstimate that the last power blackout will come about 2020 for the USA.

Global oil production peaked in 2008 and is now declining terminally.

Within a year or two, it is likely that oil prices will skyrocket as supply falls below demand.

Independent studies indicate that global crude oil production is now declining from 74 million barrels per day to 60 million barrels per day by 2015. During the same time, demand will increase. Oil supplies will be even tighter for the U.S. As oil producing nations consume more and more oil domestically they will export less and less. Because demand is high in China, India, the Middle East, and other oil producing nations, once global oil production begins to decline, demand will always be higher than supply. And since the U.S. represents one fourth of global oil demand, whatever oil we conserve will be consumed elsewhere. Thus, conservation in the U.S. will not slow oil depletion rates significantly.

Alternatives will not even begin to fill the gap. There is no plan nor capital for a so-called electric economy. And most alternatives yield electric power, but we need liquid fuels for tractors/combines, 18 wheel trucks, trains, ships, and mining equipment. The independent scientists of the Energy Watch Group conclude in a 2007 report titled: “Peak Oil Could Trigger Meltdown of Society:”

“By 2020, and even more by 2030, global oil supply will be dramatically lower. This will create a supply gap which can hardly be closed by growing contributions from other fossil, nuclear or alternative energy sources in this time frame.”

With increasing costs for gasoline and diesel, along with declining taxes and declining gasoline tax revenues, states and local governments will eventually have to cut staff and curtail highway maintenance. Eventually, gasoline stations will close, and state and local highway workers won’t be able to get to work. We are facing the collapse of the highways that depend on diesel and gasoline powered trucks for bridge maintenance, culvert cleaning to avoid road washouts, snow plowing, and roadbed and surface repair. When the highways fail, so will the power grid, as highways carry the parts, large transformers, steel for pylons, and high tension cables from great distances. With the highways out, there will be no food coming from far away, and without the power grid virtually nothing modern works, including home heating, pumping of gasoline and diesel, airports, communications, water supply, waste water treatment, and automated building systems.

If we project forward and imagine what might happen if there is another World War, when many of the technologies you mention are unleashed and ethical restraints are lifted, we could see changes in our world that are difficult to even imagine now. Perhaps the outcome would be some kind of Singularity, evolutionary leap or cultural revolution. My feeling is that emerging technologies such as nanotech, biotech and robotics/AI are so non-linear and destabilizing that they could bring about the end of technological civilization or even life on earth, giving us the solution to Fermi’s paradox in our time.
