Wind does make sense. They are profitable now. There are several companies, most in the very windy west and one going up in Nantucket Sound that are private companies making money off wind. It may not be as profitable as coal and oil right now, but it is getting there. And these farms are helping to push that along. And I would personally like to see more of these operating at lower profits and keeping our environment cleaner.
Utilities now are adding solar and wind turbines to their existing infrastructure as they are needed in the community rather than build entirely new fossil fuel plants that won't be working to anywhere near capacity for over 30 years.
Personal turbines and solar cells may take about 20 years to pay for themselves but they do it eventually, and with energy prices expected to rise even the current crop may pay themselves off more quickly. Plus the peace of mind that you are that much friendlier to the environment.
Solar may not be viable everywhere, but there are low wind requirement turbines now that are capable of powering a personal residence. Tax credits will get these in more peoples homes and stimulate research to improve on them. (And I mean very rural homes, as a turbine and it's anchor wires are a hazard in a neighborhood.)
