Ski resorts in the U.S. (and the world) view themselves as chic poster boys for global warming. With temperatures rising, one of the first visible phenomenon is less snow at resort-level altitudes. Projections in California’s Sierra Nevada mountains and the Rockies look at 5-6 degree temperature increases by 2100 if global warming is not dramatically reduced. Snow pack would fall by 89%. Ski resorts have embraced anti-global warming politics and measures with a bear hug.

This year, the White House and Rockefeller Center switched their Christmas lights from incandescent mini-bulbs to light-emitting diodes.

On Tuesday, Google announced that it plans to invest heavily in renewable energy technologies in the coming years. The project, which Google is calling "RE < C" — renewable energy cheaper than coal — will initially focus on solar thermal technologies. The goal is to create technologies and infrastructure capable of producing one gigawatt of electricity (enough to power San Francisco) within the next few years.

The December 2007 issue of Popular Science contained a section called "Best of What's New 2007" in which the "Innovation of the Year" was the Nanosolar Powersheet. These solar cells would harness solar power without using a panel. Instead, thin solar cells could be easily mounted on homes in shingles or window coatings and may revolutionize how the world gets its power.
