Energy and economy

  • The human development

index (HDI) measures standard of living

  • HDI goes up with energy

consumption, but with diminishing returns

  • > 50 GJ/year/capita of

energy use produces a good standard of living

  • Energy consumption of

human body at rest: 100W

  • r 3.15 GJ / year

The fjnite nature of fossil reserves

  • Underlying global demand for energy by

2050 could triple from its 2000 level if emerging economies follow historical patterns of development.

  • Ordinary rates of supply growth --

taking into account technological, geological, competitive, fjnancial and political realities -- could naturally boost energy production by about 50%.

  • This gap – this Zone of Uncertainty – will

have to be bridged by some combination of extraordinary demand moderation and extraordinary production acceleration. So, we must ask: Is this a Zone of Extraordinary Opportunity or Extraordinary Misery?

Climate change and energy use

Energy is not the

  • nly GHG emitter,

but certainly it is the biggest.

Richard Feynman on energy:

There is a fact, or if you wish, a law governing all natural phenomena that are known to date. There is no known exception to this law – it is exact so far as we know. The law is called the conservation of energy. It states that there is a certain quantity, which we call “energy,” that does not change in the manifold changes that nature undergoes. That is a most abstract idea, because it is a mathematical principle; it says there is a numerical quantity which does not change when something happens. It is not a description of a mechanism, or anything concrete; it is a strange fact that when we calculate some number and when we fjnish watching nature go through her tricks and calculate the number again, it is the same. It is important to realize that in physics today, we have no knowledge of what energy “is.” We do not have a picture that energy comes in little blobs of a defjnite amount. It is not that way. It is an abstract thing in that it does not tell us the mechanism or the reason for the various formulas.
