Solar Shades: If you lower your energy costs, you not only save money but you reduce your CO2-sinning that is driving climate change and you reduce energy inflation. A decade ago, Bob Barnett--DIBs-- implemented solar shades which benefit from the basic principle of quantum physics--black body radiation. The cost was $25 plus a couple of workhours. He cut his annual heating costs by thousands of dollars--see Solar Shades for why and how. Want to lower your thermometer by ten degrees--see Sock Handwarmers. Another, better simple solution awaits enough supporters of 24in4. If you would like to see others lower their enegy costs and lower their CO2-sinning for a safer future, please sign up another friend.
