Dear Editor, Re: “There Goes the Sun” [News, July 28]: Dan Mottola's story is a good piece of solid reporting. I have watched the development of solar for a good 40 years, and I can't believe the same benighted lack of vision is still slanting our perception and hampering efforts to turn this country's misuse of energy around. The ignorance of the affluent and their lack of social responsibility as indicated by McMansions with four furnaces and six air-conditioning units tells me they do not and perhaps cannot comprehend that we all have an obligation not to leave our children saddled with a crushing enslavement to an energy system designed to benefit only our energy aristocracy.
