But, yeah, the way the government did handled the whole thing left a lot to= be desired.

After a few minutes of use= it tipped over and shattered in a very large number of sharp splinters; bu= lb working life <25 minutes. Late last year Efficiency NS featured a promotion for LEDs; free bulbs = or bulbs at a reduced cost over a period of about two months. So I bit and = found the free bulbs had been available only for a day or so at select loca= tions but reduced prices were still in effect on some types at some locatio= ns. They were able to recommend the types of LED bulb which had a frequency= profile similar to incandescent and had a list of outlets that sold LED bu= lbs, and a list of bulb types sold in NS but no list of locations that sold= any particular kind of bulb and could not understand why anyone would want= that kind of information. Recently I bought an LED bulb when a bed lamp gave out and returned it = without even screwing it into a socket; only the distal end was transparent= , so it would resemble a searchlight, it was very heavy and the strong hold= er that was recommended for it had no switch. So convenient. LED bulbs make perfect sense outdoors, where any heat generated is trul= y wasted, and in flashlights. And I have three LED flashlights. One had a l= ife expectancy of 100,000 hours but the switch stopped working after ~5. From a personal point of view, I am 80 years old, so why is an expensiv= e bulb that is reputed to last 30 years such a bargain ? I have always been= careful to have as small an energy footprint as possible. No air condition= ing, no dryer, usually walked to work etc. And I have records of power, gas= oline and oil usage from 1967 onward (used wood as the major hear source si= nce 1981; carbon neutral except for cutting and hauling). When we had a cot= tage at Sunken Lake, NS Power changed the meter twice in ~30 years because = they were sure nobody would use so little power. If government really wanted to conserve energy then they could save a g= reat deal with a few strokes of a pen. I use a truck mostly to haul my fire= wood and typically put on about 1,000 km per year. But to renew the license= costs me as much as it costs someone who drives 100,000 km a year. If the license fee were proportional to distance traveled then there wo= uld be a greater incentive to car-pool when possible and a greater incentiv= e to live closer to work or use transit; decreasing not only gasoline consu= mption, but energy associated with motor vehicle repairs and energy associa= ted with wear and tear on highways and provision for high traffic volumes. = Similar considerations apply to insurance. There is a slight reduction for = vehicles driven less than 10,000 km per year but there would be a real ince= ntive to drive less if insurance cost were more proportional to distance dr= iven (expected in the first year and in the previous year subsequently).
