Changing the World One Kilowatt at a Time
Last fall, Google launched a new initiative to develop renewable energy that is cheaper than coal — and in less than a decade. Google is investing in companies that are working on high-altitude wind power, solar thermal and enhanced geothermal power, as well as beginning its own research and development.
Megan Sever

Desert Power: A Solar Renaissance
Renewed interest in alternative energy technologies has brought solar power back into the spotlight. But instead of solar cells powered by sunlight, companies are turning to solar thermal technologies — and the world’s deserts may soon bloom with thousands of mirrors harnessing the sun’s heat.
Carolyn Gramling

The Wind Over the Waves
Offshore wind has the potential to meet much of the world's electrical demand and is beginning to do so in Europe. But plans to utilize this power in the United States have been controversial. Texas is leading the way in the Gulf of Mexico, but the fate of plans in other states remains uncertain.
Erin Wayman

Design Issues in Climate Policy: How Cap-and-Trade Took Center Stage
In the 110th Congress, at least seven economy-wide cap-and-trade bills have been introduced. Why almost all climate-related legislative proposals focus on cap-and-trade is worth exploring.

Education: Preparing Students for Geosciences of the Future
Society faces an ever-expanding number of difficult challenges — and geoscience students can prepare to help meet them.

GEOLOGIC COLUMN
A False Report, A Rumor, A Hoax
Geologists take safety seriously, planning ahead for almost any scenario. Unfortunately, it’s the human element that can’t be planned for, as tragic events like the shooting at Northern Illinois University show.
