Hot dry rock geothermal energy makes use of hot fluids found naturally in basement rock; but such HWR conditions are rare. By far the bulk of the world’s geothermal resource base (over 98%) is in the form of basement rock that is hot but dry—with no naturally available water. This means that HDR technology is applicable almost everywhere on earth (hence the claim that HDR geothermal energy is ubiquitous). Typically, the temperature in those vast regions of the accessible crystalline basement rock increases with depth. This geothermal gradient, which is the principal HDR resource variable, ranges from less than 20 °C/km to over 60 °C/km,
What the World Needs Now Is Love assassination, and Martin Luther King, Jr., and soundbites of news coverage of each assassination. The ending of the song is a reprise of the introduction. "What the World Needs Now is Love/Abraham, Martin and John" rose to No. 8 on the "Billboard" Hot 100 in August 1971, and was Clay's only Top 40 hit.
