    The U.S. Department of Energy also formed its Synthetic Fuels Program, which promoted large-scale oil shale development and was involved in the prototype lease tracks in the Piceance Basin of Rio Blanco Country, Colorado. [6] In 1980, it was allotted a $2.616 billion budget for three synthetic fuel projects. [6]
