Energy for tomorrow : division 2 energy and the environment = Energie demain. End-use/least-cost investment strategies. World Energy Conference [14, 17-22 Sep. 1989, Montreal].



The energy problem was classically viewed as simply where to get more energy --more of any kind, from any source, at almost any price. Since 1976, however, an alternative paradigm has been proving its worth. This end-use/least-cost view starts by asking what the user wants the energy for, and how much energy, of what scale, from what source, will do that task in the cheapest way. This economically grounded approach seems to have more tractable problems than the supply-driven view, and has permitted improved foresight into consumer behaviour in the emerging, turbulent, mighly competitive energy-service marketplace. End-use/least-cost analysis, or (equivalently) competitive-market outcomes, could in principe yield any mix of marginal investments in supply or efficiency. In practice, however, most efficiency costs so little that under fair competition in captures almost all marginal capital. Revolutionary changes in efficiency technologies, their financing and delivery techniques, and their regulatory and cultural context now create astonishing potential savings. Full practical use, in existing U.S. building and equipment, of the best oil-and electricity-saving technologies already demonstrated (and, for electric savings, on the market) would save ~75 percent of total present use while providing the same or better services. The average levelized societal internal cost of such savings would respectively be <$10/barrel (less than domestic oil-finding cost) and <$0.01/kW-h (less than the operating cost of existing thermal power stations)...Ver documento.
