As I have mentioned, the Solar Power International show a few weeks ago was a beehive of activity: 27,000 people busily learning, networking, excitedly establishing new business connections. As Americans, we need to be proud of this industry. Here are a few data points

roofs
Using lighter colors for rooftops and streets worldwide could help reduce global temperatures and offset the heat from as much as two years of global greenhouse gas emissions, according to a new study. After examining the results from a global land surface model from NASA Goddard Space Flight Center, researchers at the Lawrence Berkeley National Laboratory
The U.K.’s Institute of Mechanical Engineers has proposed three geo-engineering schemes officials say could be immediately implemented to slow global warming: building artificial trees that absorb large amounts of carbon dioxide, using algae tubes to pull CO2 from the atmosphere, and painting the roofs of buildings white.
The engineers said that these three ideas, if carried out on a wide scale, could absorb much of the CO2 produced annually in the U.K. and cool temperatures.
The engineers shied away from more ambitious geo-engineering proposals — such as seeding the oceans with iron to encourage the growth of CO2-absorbing plankton — and focused instead on practical solutions that could be carried out soon.
