Rosemanowes Quarry, near Penryn, Cornwall, United Kingdom, was the site of an early experiment in extracting geothermal energy from the earth using hot dry rock technology. The site was chosen because the granite in the area has the highest heat flow in England (120 milliwatt per square meter) [1].

The trials began in 1977 in the wake of the 1973 oil crisis and an earlier trial in the United States at Fenton Hill. It concluded in 1980. Funding was provided by the Department of Energy (now the Department of Trade and Industry) and by the European Commission [1].
