Fracking may become a greener process — NewsWorks
President Barack Obama outlined a national energy policy this week that includes tapping domestic natural gas reserves. The president assigned his Nobel Prize-winning Secretary of Energy to come up with a safer way to drill.
In his speech, Obama said Secretary Steven Chu is the best man for the job.
"And this is the kind of thing he likes to do on the weekend. He actually goes into his garage and tinkers around and tries to figure out how to extract natural gas,” said the president to laughs.
But hydraulic fracturing, or fracking, is no joke to those who oppose it. The controversial process uses high-pressured water, chemicals and sand to break up underground rock that holds the deeply buried gas.
The chemicals, and the resulting wastewater from the process, have people worried.
