Feb 14 2009. Join the Group Read. Chapters 7, 8 and 9. Heat, hydro and light
(Instructions on how to join are at the bottom of the original post)
We use about as much to heat and cool ourselves (in Britain) as we use to move around in our cars, while lighting uses only a fraction of that energy - especially using low energy fluorescent bulbs or the new generation of LED lights. Hydro-electric power in Britain, however, even with generosity from the wet Highlands, will only deliver about one third of the small amount of energy we use to light ourselves. How unfortunate that such accidental power-concentrators as mountains and streams are not more plentiful, and not just, maybe, for the energy benefits.
