The per capita energy demands of 1800 were of course much lower, comparable one would guess to the demands of a modern day Nigerian.
Life expectancy in Nigeria is a little over 43 years.
http://allafrica.com/stories/200509260160.htmlOf course, if everyone tried to live like Nigerians live (not that the Nigerians live that way by
choice) we would not have to worry too much about the fact that 8 billion people each consume less than 8 watts of power on average. I rather think that the new environmental problem might be how to dispose of 7.5 billion dead bodies.
People like to focus on how dangerous energy is, and they are right, energy
is dangerous. However the absence of energy is even more dangerous.
I note, since the renewables industry is
still tiny and largely insignificant on a grand scale, it remains to be tested whether it is environmentally sustainable or safe either. For instance, the much hyped biofuels industry depends of course on agriculture. In a time of rapid global climate destabilization it is probably a poor bet to assume that there will continue to be agricultural surpluses to provide
any capacity for biofuels.
We are at a stark fork in the road, and no path ahead is well paved and easy to travel. There is going to be tragedy. Energy efficiency is just as important as it has always been, but people who pretend that the matter can be addressed by efficiency and the completely unproven and poorly scaled renewables industry alone, are selling either a Nigerian lifestyle or coal.
If the renewables as savior claim could prove otherwise, a
significant renewables industry would already exist and not just in rich countries with big subsidies available, but everywhere. Everybody loves renewables. Renewables are sexy. Renewables are cool. People have been praising the potential and hope of renewables for more years than are probably represented by the average age of DUers. Renewables have just one, and only one tiny little problem: They just don't work very well.
Coal, on the other hand, will kill us for sure, and the mimicking Nigeria might extend our time a little longer, but with a little common sense - including broad promotion and practice of family planning and, as I often point out, increasing the status of women, providing decent health care, the encouragement of secular government, increase in education - and of course by constant refrain, by the use of nuclear energy, we can do much much better than either Nigeria or coal.
There is a third thing that is as deadly as coal or the Nigerian lifestyle, a third thing that is sure to kill us. It's called Denial. Like they say, it ain't a river in Egypt.
