Abstract

U.S. energy consumption is reviewed from a top-down approach with special emphasis on thermal energy consumption in the residential, commercial, and industrial sectors. The solar thermal R&D efforts of the past 10 years at UC Merced are then presented which detail (i) a low cost combined heat and power collector (PV/T) for space heating, hot water, and electricity (ii) a nonimaging integrated compound parabolic concentrator (ICPC) with phase change thermal energy storage (TES) for low cost (< $0.015 / kWh_th) dispatchable (24/7) solar for 120 °C process heating (iii) a mediumtemperature external compound parabolic concentrator (XCPC) for 100-250 °C process heat which has been used to demonstrate efficient solar cooling and solar driven wastewater evaporation for brine management, and (iv) a two-stage high concentration parabolic trough collector with a nonimaging secondary to achieve < 650 °C operation.
