8. What is the concept of precious energy and how does this help us think about energy efficiency?
Precious energy refers to the fact that some is from non-renewable sources (perhaps too much) and that we need to use it sparingly for reasons of economic and environmental sustainability. The fact that certain forms of energy are limited, means that we do use them, we need to do so as sparingly as possible. There is also the fact that in certain parts of the world there is not enough energy to go round. So this is another reason for making the most of what we have got, while bearing in mind energy use must be sustainable - that is whilst meeting our own needs, making sure that we do not stop future generations meeting theirs. So not only do we need to use fossil fuels with extreme care, we need to develop renewables whenever and wherever we can, especially in those developing areas where their is extreme shortage. @http://www.hedon.info/index.htm alternative energy in the less developed world
