Although technology change (usually involving an improvement in energy efficiency) is not inherently a geographic process, it does not occur uniformly over geographic space. Consequently, mathematical modeling and behavioral and innovation diffusion studies by geographers have improved our understanding of the pervasive phenomenon of technology energy efficiency change in energy markets. Similarly, creative government policies in Germany since 1990 have led to a faster rate of adoption of renewable energy sources, compared to the United States. (more…)

Energy labeling is a policy tool that informs consumers about the energy performance of appliances and thereby encourages them to purchase appliances that provide the services they need with less energy consumption. In providing information to consumers about equipment energy consumption and operating costs that would otherwise be invisible or unavailable, energy labeling enables consumers to make more balanced and rational purchasing decisions. Energy labels can also help consumers to identify the most efficient products on the market. In effect, energy labeling attempts to provide a market ‘‘pull’’ for more energy-efficient products while simultaneously presenting information that might discourage the purchase of less efficient products.

In Europe, modern renewable energy sources technologies were explored thoroughly for the first time after the oil embargo/ price crisis of 1973. Notably, market introduction of renewable energy technology started in about 1985, but the renewable energy sources industry has become vital only during the past decade. Accordingly, relevant statistical renewable energy sources data have been systematically compiled only over the past decade, although reliable and consistent statistical renewable energy sources data, collected since 1989, exist for all 15 countries of the European Union and for Western Europe (defined here as the EU-15 plus Switzerland, Norway, and Iceland).

There are various and somewhat complementary reasons to foster the growth of renewable energy sources in Europe. A major incentive for renewable energy sources policies in the past two decades has been to reduce the environmental impact of energy use both locally (e.g., pollutant emission reduction) and globally (e.g., greenhouse gas and carbon emissions reduction). In some countries, concerns about the safety of nuclear power generation have motivated the search for renewable energy sources. Another motivation for replacing foreign fossil and nuclear fuels with domestic renewable energy sources relates to security issues and Europe’s growing dependency on foreign energy sources. (more…)

The energy efficiencies of various fuel production pathways from well to pump. The efficiencies shown are defined as the energy in a given fuel (available at pumps in vehicle refueling stations) divided by total energy inputs during all Well-to-Pump activities, including the energy content of the fuel. One way to interpret the Well-to-Pump efficiencies in the figure is as the difference between 100% and the energy efficiencies, which roughly represent energy losses during Well-to-Pump stages for making a given fuel available at the pump. As stated in Section 3, Well-to-Pump activities include biomass feedstock production; feedstock transportation and storage; fuel production; and fuel transportation, storage, and distribution.

Electric and gas utilities’ Research & Development activities deal nearly exclusively with energy conversion, distribution, and energy usage (at least to the extent that these firms still focus on these core businesses). Although detailed data on utility Research & Development are not collected systematically, it seems that Energy R&D spending by many utilities has declined during the past decade or so. For example, a 1996 survey by the U.S. General Accounting Office (GAO) found that the combined Research & Development spending of the 112 largest operating utilities in the United States dropped from $708 million in 1993 to $476 million in 1996.

Energy performance ratings tell what the energy performance of a building is, but if the energy performance of a building is to be improved, the causes of lower than desired performance must be understood, and methods of achieving improved performance must be determined. Causes of variation in energy performance among commercial buildings are understood to a degree, but much remains to be learned. (more…)

The combination of well-to-pump results and the energy use and emissions associated with vehicle operation (also called the pump-to-wheels stage) results in full well-to-wheels energy and emission results for vehicle/fuel systems. The energy efficiencies of 19 fuel pathways were presented in the preceding section. The well-to-wheels energy use and emissions results for 23 representative vehicle fuel systems, combined with some of the vehicle technology options are now considered. (more…)
