Federal policies moved in coal's favor in the 1970s. With the Middle East oil crisis, policymakers began to adopt policies to try and shift the nation toward greater coal consumption, which was a domestic energy resource. The Energy Supply and Environmental Coordination Act of 1974 directed the Federal Energy Administration to prohibit the use of oil or natural gas by electric utilities that could use coal, and it authorized the FEA to require that new electric power plants be able to use coal. The Energy Policy and Conservation Act of 1975 extended those powers for two years and authorized $750 million in loan guarantees for new underground low-sulfur mines. Further pro-coal mandates were passed in the late-1970s.
