I am looking for research that might suggest that, in the long run, using cheap solar lights is actually less environmentally friendly than using well made, long lasting lights. The public's perception is that solar lights use less energy than traditional low voltage systems. While this may be true on the individual's level (even though they look like crap), is it true from a macro standpoint in terms of manufacturing, replacement frequency, waste, etc? How much energy might the companies be using that are making cheap lights, sold by the millions, and replaced by the millions, because they don't last? I think that if people really want to go green, then they should be purchasing products that last, so that there is less waste in this world. Any thoughts?
