On this episode of “Illustrated Daily,” we discuss geothermal energy. “A recent survey by the USGS pointed out that there is a potential of 3 million quads of energy available using the hot dry rock technology. A quad is the equivalent amount of energy that the sun deposits upon the earth in one day. It's 100,000 BTUs. The Department of Energy conservatively estimates that you might be able to use 2% of the three million quads, which would give you then 260,000 quads of energy. The United States, in 1977, used a total of 78 quads for all sources of energy including automobiles and heat.” Reporter: Ricardo Trujillo.
