  1. Solar Roofs May Cut Bills in Half (CNN )
      Provides an article about roof tiles that may cut the electricity bills for a home in half, at least in California. The initial purchase of the roof tiles is also subsidized in California. 10-00

  2. Roofing - Solar Roofing and Laminates (Uni-Solar)
      Describes solar laminated panels that can be applied to roofs or other surfaces. 6-01

  3. Solar Roofs May Cut Bills in Half (CNN )
      "In the 1970s, going solar meant mounting panels the size of ping-pong tables in cumbersome racks on your roof. But in the past five years, the industry has become more architecturally savvy, offering up solar-powered shingles that blend almost seamlessly with traditional roofing materials." 03-08

  4. -10-31-08 Thin Film Solar (
      "There are countless ways to manufacture solar panels, but there's only one metric that counts: how the cost of solar power compares with that of electricity from fossil fuels. Until energy from the sun can beat energy from coal at the marketplace, solar will remain a niche player, adorning the rooftops of those who care more for their green reputation than for their bottom lines. Enter Nanosolar, a San Jose-based start-up that manufactures thin-film solar panels. Unlike the bulky silicon panels that dominate the solar market, Nanosolar thin-film technology is light and extremely cheap to make. The key is the manufacturing process: while silicon panels need to be baked in batches, Nanosolar's thin-film panels roll off the assembly line, as if from a printing press." 07-08

  5. Cool Roof (
      "In the world of industrial and commercial buildings, a roofing system that can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the building) and high thermal emittance (the ability to release a large percentage of absorbed, or non-reflected solar energy) is a cool roof. Most cool roofs are white or other light colors." 09-09

  6. Cool Roof Materials and Colors (
      "If you're replacing the whole roof deck, you can easily install radiant barriers at the same time. In fact, there's a radiant barrier currently on the market that's attached to plywood. You can use it in place of standard decking, with the aluminum foil facing down into the attic. The material doesn't cost much more than standard decking, and the installation process is the same, so there is no extra labor involved. In very hot climates this is a sensible, cost-effective, and easy retrofit."

      A bright white coating (ceramic, elastomeric) on a smooth surface can increase solar reflectance to 90%, limiting the rise in temperature of the roof by 15 degrees over outdoor temperature. Black shingles, in contrast, provide 5% solar reflectance and can allow the roof temperature to rise 90 degrees over outside temperature. 07-11

  7. Global Reflective Cities Effort (Global Cool Cities Alliance)
      "Global Cool Cities Alliance will accelerate a world-wide transition to highly reflective, cooler, healthier cities. Its mission is to advance policies and programs that increase the solar reflectance of our buildings and pavements to promote cool buildings, cool cities, and, most importantly, to mitigate the effects of climate change through global cooling." 09-12

  8. -100 Companies Provide 71 Percent of CO2 (
      "According to a recent report by George Mason and Yale universities, more than half of Americans (58%) believe climate change is mostly human-caused. As a result, more and more people try to manage the carbon emissions of their lifestyle. They buy electric vehicles or put solar panels on their roofs. Maybe they eat less beef and if they do buy beef, bring their own bag to the supermarket. Everything helps, but there’s one thing that really has a big impact on reducing emissions that receives little attention."

      "In order to explain this let’s go back to this past summer, when CDP, in conjunction with Climate Accountability Institute, released a report detailing that 100 companies have been responsible for ~71% of the world’s greenhouse gas emissions."

      "That’s a staggering number." 02-18
