Ohio University is switching its Lausche plant from coal to natural gas for the summer.
The university said it was able to secure enough fuel to run the plant for five months because of low prices for natural gas.
The university will pay less for natural gas than it did for coal. It is the first time that the cost of natural gas is lower than coal for the university to make such a switch possible, the school said.
The Columbus Dispatch reported recently that the university's trustees are battling with Columbus over who controls drilling on college campuses.
The Ohio U trustees passed a resolution saying they have final control under a new state law that opens property at Ohio colleges. It is House Bill 133..
University officials said they are confident they can veto drilling proposals advanced by the state. But it is unclear under the law whether the state has the authority to override such local vetoes.
