CLEARFIELD, Pa. -- The use of ethanol as fuel has come under fire from some politicians.

Just last week, Texas Governor Rick Perry said federal ethanol programs are to blame for rising corn prices.

In Clearfield County, two ethanol plants are under construction in Lawrence Township and Curwensville.

County officials said they're not concerned about the current backlash against ethanol.

"People need to understand that we need to move toward these alternative sources of energy," said Commissioner Mark McCracken.

According to McCracken, these ethanol plants will originally use corn but will eventually branch out to include other sources of ethanol, such as wood chips.

Construction on both plants should be completed within the next few years.

McCracken said Clearfield County is also supporting alternative uses of coal such as a new waste-coal plant near Karthaus.
