U.S. House warned of coal's potential demise in 1966

Interesting view from a 1966 report from the House of Representatives:

From: STAFF OF SUBCOMM. ON SCI, RESEARCH, & DEVELOPMENT OF THE H. COMM. ON SCI. & ASTRONAUTICS, 89TH CONG., REPORT ON ENVIRONMENT POLLUTION: A CHALLENGE TO SCIENCE AND TECHNOLOGY22 (Comm. Print 1966).

This appears in Struggling for Air: Power Plants and the "War on Coal," Richard L. Revesz & Jack Lienke, Oxford University Press, 1966 p. 119.
