Green Options

Researchers at Lawrence Berkeley National Laboratory released a study this week concluding that the solar industry could use many cheaper and more abundant alternatives to silicon, including iron pyrite — most commonly known as fool’s gold.

In total, the researchers found 23 alternative semiconductors, but only 12 are more easily found than silicon. Iron pyrite was named the most probable solution among those 12. Solar producers have often faced shortages of silicon, so even one new material would be a welcome jolt for the industry.

The Sunshine State might have a lot of catching up to do when it comes to solar energy installations, but it’s now on a fast track toward big improvements.

The tide began turning when Gov. Charlie Crist, a Republican with a strong environmental sentiment and an affinity for renewable energy, first took office. Then came the debut earlier this year of Florida’s largest solar array to date, a 250-kilowatt installment in Sarasota County.

And now comes the news that Florida Gulf Coast University (FGCU) in Ft. Myers has been singled out by state lawmakers for an $8.5 million allocation to build a 16-acre solar farm on its campus. While the funding still needs a final OK from Crist, who’s likely to approve, the money would help FGCU construct what would be the largest university-based solar farm in the world.
