Peak Oil? No Need to Panic By Owen McShane, The NewZealand Herald | Apr 15, 2005 http://www.nzherald.co.nz/index.cfm?c_id=466&ObjectID=10120491
The Greens are so happy. They have discovered "Peak Oil", a theory claiming oil production has peaked, supplies will decline and prices will go sky-high. Civilisation will literally grind to a halt. We'll all be back in trains where we belong. The Greens are arguing against building more roads, that further investment in aviation is foolishness and that the Government should sell its shares in Air New Zealand. With empty tanks those birds won't fly. Similar predictions have been made before. English industrialists worried they would run out of coal. The Royal Navy thought it would run out of timber spars. Machine makers thought they would run out of whale oil. Computer analysts worried they would run out of the copper to connect all the PCs. Paul Erlich was convinced that by now we would have run out of just about everything. Fortunately, no one took any notice then. We should take no notice now. It's true that for the past few decades the world has enjoyed incredibly cheap oil. Although the wells are distant, refining is complex and fuel is subject to huge taxes, the petrol powering your car is cheaper a litre than most bottled water - including New Zealand water. (So who's profiteering?) The Peak Oil theory claims we are using oil faster than we are discovering new supplies. We should not be surprised. Oil has been so cheap and plentiful (two ways of saying the same thing) that it has not been worth looking for more of it. Much of the oil in known reserves needs a higher price to make it worth extracting. Some is "taxed" by environmental restraints. Now that prices are high, the oil companies are exploring again. Governments are providing the appropriate incentives. The United States uses only half the oil for each unit of production that it did in the mid-1970s. The vehicle fleet is hugely more energy-efficient and grows more efficient by the day. The latest four-wheel drives use computer controls to automatically switch from V8s to V4s in cruise mode, so the high power is delivered only when needed. Electric hybrids such as the Prius double fuel efficiency. World population collapse is just around the corner - let's say 2050. This coupling of population decline with increased efficiency will compensate for increases in energy use. Oil is only one source of energy. If it gets truly expensive, the future will still be awash with energy because so many new sources are waiting in the wings for oil to get more expensive. New energy sources are all around us. All energy is nuclear, including solar and geothermal. Gravity originates in the nucleus. Hydro-dams combine solar energy with gravity. So do the tides and so does the wind. Coal stores old solar energy. Oil stores old geothermal power and gravity. The Earth is awash with nuclear power from the sun. There are scores of ways to tap into it so our future will be awash with energy, while oil will give us time to make the transfer. But surely, eventually, the oil must run out? No. No natural resource ever runs out. Once there were only two of us. Now there are more than six billion of us, yet no mineral resource has ever run out. As any mineral or similar resource gets scarce, the price increases until it is not worth using and substitutes step in after waiting in the wings. Sometimes new technologies simply sweep the old ones aside. We switched from sail to steam but not because we were running out of wind. But let's concede that the era of ludicrously cheap oil may well be over and that the next round of oil will be more expensive because it will be more difficult to find and to extract. What happens, for example, when petrol hits, say, $5 a litre at the pump? At that point it is worth converting coal into fuel oil using present technologies. Well before that happens, converting or modifying other oil-like reserves, and using more expensive forms of natural gas, become worthwhile. New Zealand sits in the middle of an "ocean" of natural gas, including "frozen methane" offshore. Waste-to-energy plants can produce electricity and new technologies can turn waste biomass directly into oil. Windmills on your roof will dissociate water into hydrogen for the fuel cell in your car. Physicist Freeman Dyson predicts that genetic modification will soon make trees and plants much more efficient at capturing solar energy. Carter Holt may grow GM forests to burn as biomass. Dyson also predicts the development of plants that produce fuel oils directly from their roots. Every garden will have its high-octane corner. The Alberta oil sands contain the equivalent of 1.6 trillion barrels of oil, more than all of the world oil reserves combined. A higher price will turn this resource into a reserve. A shrewd guess is that a bunch of new technologies will allow us to stabilise around a plateau of supply and demand which delivers petrol at about $2.50 a litre. That's twice today's price, but if your new hybrid motor car delivers twice as many kilometres a litre, you will be no worse off. This more expensive fuel oil will be directed to aircraft and to motor vehicles where it delivers the most benefits. Electricity generators will switch to nuclear fuel, coal and useful renewables such as solar power, geothermal energy and biomass. Finally, we will be able to afford even higher prices for our cars if we need to. The average household income for the Auckland region is about $66,000 a year. After 100 years' gross domestic product growth at, say, 3 per cent a year, that income will be more than $1 million a year. The average household could afford to pay $30 a litre to fill the tank. So don't panic. Oil will be around for a long time. And so will cars and planes. However, the Oil Age will certainly end before we run out of oil. Just as the Stone Age ended long before we ran out of rocks. * Owen McShane is the director of the Centre for Resource Management Studies. ------------------------ Yahoo!
