The good news: Lawrence Berkeley National Laboratory (LBNL) researchers are developing technologies that in the future will help produce new commercial buildings that use 80% less energy than today’s buildings. More here.

The bad news: "A recent Electric Power Research Institute study projects that greenhouse gas (GHG) emissions from China and other developing countries are growing so fast that they would push global atmospheric GHG concentrations beyond 450 parts per million (ppm) by the year 2070 (up from a level of 275 ppm about two centuries ago, and 380 ppm nowadays), even if all emissions from industrialized countries such as the United States and those in Europe were reduced to zero today."
