A lot happens in America every four minutes. During that short time period, 30 babies are born, 4,080 McDonald's Big Macs are consumed, and 48,000 tons of CO2 are emitted.
And as it turns out, the U.S. is now installing one solar photovoltaic (PV) system every four minutes as well. If market growth continues at its current pace, the American solar industry could be installing a system every minute and twenty seconds by 2016.
That's a dramatic difference from 2006, when installers were only putting up one system every 80 minutes.
