The following figure was posted on Dr. David MacKay’s, Chief Scientist at DECC, at his blog at Sustainable Energy. He announced a new version of their 2050 Calculator tool which I’ve not yet had a chance to play with. However, the following figure, which can be produced by the tool, shows how energy flows. I’ve seen similar diagrams for the USA and it’s roughly the same.
This is an important and key way we should understand energy. How often do I hear that someone state the “solution” to the energy “crisis” is to fix efficiency. “We waste so much energy in our homes! We need the government to provide more grants for better home insulation and we’d fix this problem.”
Study the following figure and see if you agree. Are there other strategy targets we should look into? I think so. Click on the figure to get a bigger image.
