The oil bust has spoiled the economics of alternative energy as well. Many of the ballyhooed 1970s-era programs to extract petroleum from oil shale and tar sands have been mothballed because they cost too much to operate.

Today's burgeoning industry is a testament to both government incentives and oil-company determination...
