While the relations between climate variables and sectoral water demand have been well established in the literature, few studies have attempted to quantify changes in urban water usage with climate change. Concentrating on the city of Hamilton, New Zealand, we investigate possible water use and...

"Getting the price right" is a goal of many market-orientedenergy policies. However, there are situations where the consumer payingfor the energy is separate from the owner of the energy-using device.Economists call this a "principal agent problem". A team organised by theInternational Energy...

Although the government sector represents only 10 to 15 percent of the economy in most countries, carefully targeted public procurement can play a significant role in market transformation through its influence on both buyers and suppliers. Government leadership in energy-efficient purchasing...

A new method of presenting the potential for conservation is discussed. Supply curves of conserved energy provide a consistent accounting framework for assessing diverse conservation measures. They also permit simple comparison of conservation measures among themselves and with conventional...

The combined energy consumption of US televisions and videocassette recorders was about 40TWh per year in 1998, corresponding to 3.6% of national residential electricity consumption. The average household television energy consumption was about 310kWh per year, 23% of which was used while the...

The rapidly changing energy situation has led to new analyses of energy conservation from both physical and economic perspectives. A physics perspective suggests that the technical prospects for improved efficiency remain very great. An economics perspective suggests that conserved energy may be...

We compared Home Energy Rating Systems (HERS) ratings and actual utility billing data for about 500 houses in four states. We found that HERS can, on average, predict annual energy cost accurately. However, on an individual house basis the agreement between predicted energy cost and actual...
