  • This is the world energy consumption curve, and will determine the more important aspects of our economic, environmental and political future. The green line is the historic use up to the present and the red is the projected use based upon United Nations population estimates and Deutch and Moniz (2006) assumptions for per capita increases in both developed and developing countries . Global electricity use recently passed 15 trillion kilowatt-hours per year and is projected to double by 2040.
  • If you look at the United Nations Human Development Index, which is an excellent indication of the quality of life that most humans aspire to, you can see most western countries are in the energy fat region, and we can certainly afford to conserve, buy compact fluorescence, hybrid cars, etc., so that we could drop back to where the British are which is pretty efficient overall. But there is not even a billion people in this energy fat zone. The other 5 billion are in the lower zone and they desire, and will get to, this zone, one way or another. And it will be primarily by using fossil fuel. That is what we have to change if we have any chance of reaching our goal of sustainability
  • . The present world energy distribution falls into two categories - power and transportation - and looks like this. It is very dependent upon where you live. Transportation is almost completely petroleum-based. For power, the U.S. is basically 70% fossil fuel, 20% nuclear and a little bit of everything else. New Mexico, where we live, is almost all coal. New Jersey has the highest percentage of nuclear in the U.S., and California is the most diversified, but it also has the highest cost for electricity in the U.S. Europe is a little better - more nuclear (because of France) less coal and more hydroelectric.
  • Another way to look at costs is the Energy Return on Energy Invested, or the traditional ratio of Energy Return on Investment, shown here. It is the ratio of energy invested to energy returned from that source and the larger the number the better the value, the closer to one the more it is of no use. It is no wonder that when fossil fuel came on the scene in the early 20th century the return was enormous, and our entire economy became fueled by fossil fuel, and our standard of living increased proportionately. Of course, this was the most easily recoverable deposits. [click] As time went on, it became more difficult to recover the material, took more energy and effort and the return was less. Developing the unconventional sources such as oil sands, coal liquification, and others drops the return even more. Ethanol production is the least effective of all and barely manages to exceed one. [click] Biodiesel is slightly more effective, and if oil-rich sources such as algae are used, or bio-engineering for cellulosics is successful, the return increases significantly, but never to the level of conventional fossil fuel. [click] Nuclear increases significantly after 1990 because of increases in efficiency and capacity, standardizing of designs, and increased design life. [click]
