Re: : Howard asked for comment about the piece by Richard H. Sibson. I think there are some Malthusian assumptions in this piece. What is not sufficiently considered, or is under-estimated, is the pace of technological change in oil-using means of production and means of consumption. Most notably, what isn't factored in is how technologies that use oil have the potential to become far more energy-efficient, i.e. capable of being at least as efficient while consuming less oil (or oil derivatives). Of course, one can not deny the fact that oil is a non-renewable resource and there is a limited potential world supply (even if there are different estimates of what that potential is), but there are alternatives (which for various economic and political reasons have not been exercised). I also find the claim about long-distance transportation to be unconvincing. In the short and medium-term, higher costs for air and sea transportation might indeed be anticipated (and this indeed might have an affect on travel to NZ and consequently the NZ economy). Over the longer-term, there is reason to think that alternative technologies for air and sea travel will be developed. This might involve the scrapping of the existing fleet of long-distance air and sea transport vessels (and consequently moral depreciation), but given the economic incentives to pursue alternatives in the future, I think it is reasonable to think that they will be developed ... even if that might be decades away. Sibson claims that by the mid-21st Century "the world resource of conventional oil ... will effectively be dissipated." *Even if* that is the case, we're still talking about almost 50 years ... a long enough time horizon to make any forecasts about the pace of development of alternative energies highly suspect. Hell, we don't even know if there will be human life on this planet in 50 years or whether there will or will not be fundamental revolutionary change to a more advanced mode of production during that time period.
