Global energy consumption in the last half century has increased very rapidly and is expected to continue to grow over the next 50 years. However, we expect to see significant differences between the last 50 years and the next. The past increase was stimulated by relatively “cheap” fossil fuels and increased rates of industrialization in North America, Europe, and Japan; yet while energy consumption in these countries continues to increase, additional factors are making the picture for the next 50 years more complex. These additional complicating factors include the very rapid increase fuel economy in energy use in China and India (countries representing about a third of the world’s population); the expected depletion of oil resources in the not-too-distant future; and the effect of human activities on global climate change.

The long-term prospects for the U.K. economy are inevitably uncertain, and the most recent Department of Energy long-term projection puts forward three scenarios for the next 30 years with GDP growth rates of roughly 2.5, 1.5 and 0.5% p.a. The highest value corresponds to slightly less than the 1948 - 72 average, the central value is close to the long-run average over the last 80 years, and the lowest figure is similar to the performance during the current recession since 1973.

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…)

Reductions in carbon intensity, C/E, the carbon emitted per unit of energy generated, reflect the degree to which societies decarbonize their energy sources. The long-term trend has been a shift from coal to oil to natural gas––hydrocarbons with decreasing C/H ratios emitting progressively less CO2 per joule. However, the increasing use of clean low-carbon fuels is not sustainable without somehow disposing of excess carbon because it opposes the trend in the abundance of fossil fuels, with coal resources being the most abundant followed by oil and gas.

As a reaction to these historical perspectives, the building industry has witnessed a certain rise in design responses to regional climatic conditions, as part of a powerful efficiency and energy conservation push since the 1970s. More recently, the zero green house gas emsission and office building has become a design concept as part of strategies to introduce urban renewable energy as an increasing contributor to managing urban energy supplies.

The gradual change in the energy consumption pattern of the United States from 1860 to 1990. In the mid-1800s, biomass, principally woody biomass, supplied over 90% of U.S. energy and fuel needs, after which energy biomass consumption began to decrease as fossil fuels became the preferred energy resources. For many years, a safe illuminant had been sought as a less expensive substitute for whale oils. (more…)
