Much of the research and venturing efforts in energy technology have been towards the cleaner or cheaper generation of electricity or production of fuels. All worthy efforts. But as I blogged about earlier --
Ever More Efficient GDP -- there's tremendous room for new
efficiency innovations. Towards this end, it's worth noting several compelling (albeit random) items:
Some graphs are instructive here as well. First, a very micro-level illustration of how rapidly consumer appliances can become more efficient. In this case, refrigerators (note how this appears to be in response to
1973 Oil Shock)...

Second, a graph of change in Japanese industrial efficiency, also following the 1973 shock...

And finally, a macro-graph comparing different country GDP-per-capita to energy consumption per-capita. Note the wide range of possibilities, even holding constant for variables like hot- or cold-climate places...
