Monday, October 27th, 2008My Clean Break column today takes a look at Vancouver-based Sempa Power Systems, which helps large energy customers reduce their bill and lower greenhouse-gas emissions by dynamically switching their heating requirements between fossil fuels (mostly natural gas) and electricity. Now, you might be saying to yourself: this makes no sense because electricity is too inefficient for space and water heating. True, but in certain jurisdictions off-peak electricity tends to be zero- or low-emission (i.e. nuclear, wind, hydroelectric) and wholesale prices can drop dramatically as power generators look for ways to offload what is often baseload power that can’t be easily turned down.
