BMW's new luxury hydrogen-gasoline sedans are impressive engineering efforts--but the environmental jury is still out.

I’m MIT Technology Review's chief correspondent, keeping an eye most often on the world of information and communication technologies—and asking my kids when I don’t understand what’s going on. Recent projects have taken me to Kenya to write about mobile-phone-based health initiatives, and Germany to explore how they’ll ramp up renewable power while closing down nuclear plants. My 2008 feature on the Obama campaign’s social-networking operation was selected for The Best Technology Writing 2009.

GE's advance allows for a solid-oxide fuel cell to use coal-based fuels at costs approaching that of conventional power plants.
Panelists at the Emerging Technologies Conference voiced an urgent need for aggressive policies to promote energy efficiency, renewable power sources, and carbon sequestration.
Hydrogen may never be feasible as a fuel for vehicles, but BMW is pushing ahead anyway with an advanced hydrogen-gas combustion hybrid.
Sequestration science is far ahead of needed policy.
Sequestration technology is increasingly ready for prime time, but the required policy lags behind, says MIT expert Howard Herzog.
By investing in energy efficiency, we could vastly reduce carbon dioxide emissions and save money.
Better technologies exist for extracting coal, a major source of carbon dioxide emissions. The challenge is getting people to adopt them.
The institute's energy council co-chair Ernest J. Moniz describes a sweeping agenda to meet a "remarkable challenge."
