Technology Energy Efficiency: Changes and Renewable Sources

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…)

Hydrogen Fuel Cell Powered Flight Takes Off

hydrogen fuel cell
On a bright, blue morning at Hamburg Airport, the aeronautics industry came a giant step closer to changing the future path of alternative energy aircraft. That’s the morning that the Antares DLR H-2 motor glider became the first aircraft in history to take off solely under hydrogen cell power. (more…)
