Putting fuel cell cost on the chopping block

Hydrogen fuel cells can provide power to off-grid areas, power vehicles and even generate baseload power for the electric grid. 

They are also silent and emissions-free.

Better solar may lurk in 'shadow state'

Theoretically, the maximum efficiency of today's silicon solar cell is approximately 31 percent, because much of the solar energy that hits the cell is lost as heat.

Black silicon solar tech comes of age

Black silicon has been bubbling in the background of solar research and development the past couple of years, hinting at a way to drive down the cost of solar power, but has yet to bust out.

Why the EU is winning the clean energy race

The EU signed Kyoto in 1997, and passed laws to lower emissions by 2005. Five years later it had double the wind power of the US, and ten times the solar power.

Tesla Model S weighs in at a cool 50K

Way back in 2009, when the Tesla S electric sedan was a concept living only on sketches and engineering notes, the company promised the car would retail for $49,900 following federal tax credits.
