The New York Times has an interesting article on Japanese energy technology. What always leaves me scratching my head is how this environmentally-minded country has such lousy windows and insulation which leads to more heating in the winter and air conditioning in the summer (and thus more energy consumed and greater expense). I’d also love to see an accounting for all of the energy consumed by the millions of ubiquitous vending machines!
Now, with oil prices hitting dizzying levels and the world struggling with global warming, [Japan] is hoping to use its conservation record to take a rare leadership role on a pressing global issue. It will showcase its efforts to export its conservation ethic — and its expensive power-saving technology — at next week’s meeting in Japan of the Group of 8 industrial leaders.
“Superior technology and a national spirit of avoiding waste give Japan the world’s most energy-efficient structure,” Prime Minister Yasuo Fukuda said. Japan “wants to contribute to the world,” he said.
Japan is by many measures the world’s most energy-frugal developed nation. After the energy crises of the 1970s, the country forced itself to conserve with government-mandated energy-efficiency targets and steep taxes on petroleum. Energy experts also credit a national consensus on the need to consume less. It is also the only industrial country that sustained government investment in energy research even when energy became cheap again.
Japan consumed half as much energy per dollar worth of economic activity as the European Union or the United States, and one-eighth as much as China and India in 2005. While the country is known for green products like hybrid cars, most of its efficiency gains have been in less eye-catching areas, for example, in manufacturing.
Corporate Japan has managed to keep its overall annual energy consumption unchanged at the equivalent of a little more than a billion barrels of oil since the early 1970s, according to Economy Ministry data. It was able to maintain that level even as the economy doubled in size during the country’s boom years of the 1970s and ’80s.
