MORGANTOWN, W.Va. — Solar power plants and other renewable energy sources are real, competitive threats that neither the coal industry nor the state’s political and academic leaders should dismiss, a consultant warned Wednesday at the second West Virginia Coal Forum.

While the carbon in coal has many potential applications, its future as a fossil fuel to be burned for electricity is limited, said Allan Tweddle, a member of the West Virginia Public Energy Authority.

In a discussion focused mainly on ways to ensure that West Virginia coal remains a prominent part of the nation’s energy plan, Tweddle was a splash of cold water to the face.

Germany has abandoned the coal-to-liquid fuel technology it pioneered, he said, opting instead to focus on solar power plants. South Africa, which has had the world’s largest continuously operating coal-to-liquids plant, is now planning to shut it down.

Simultaneously, the worldwide solar cell industry is growing 35 percent a year, with China spending $3 billion a year, Tweddle said. And California is looking into on-demand solar plants that he said could produce electricity that is price-competitive with coal-fired power plants.

All that growth is lowering the cost of silicone, a key ingredient that had made solar power more expensive, Tweddle said.

“The state has got to pay attention to these serious trends,” he warned. “I hear too much dismissal of these technologies.”…

The recommendations are built on the premise that while clean, renewable energy may be coming, it’s not here yet and coal must continue to fill the gap.

Even if Germany, for example, does manage to produce 30 percent of its power from solar sources by 2030, “we want to supply the other 70 percent,” said William P. “Pat” Getty, a member of Imagine West Virginia’s board of directors…

That’s why the DEP is interested in exploring former mine sites for new uses like solar, wind or even fuel-producing grass farms.

“If you’re selling a product and that product becomes obsolete, then you’re out of business,” he said. “Energy will not be obsolete. Coal may become obsolete, but energy won’t.”
