Many people associate solar energy directly with photovoltaics and not with solar thermal power
generation. Nevertheless, large commercial concentrating solar thermal power plants have been
generating electricity at a reasonable cost for more than 15 years and some new solar thermal
power plants are soon to be erected. This paper compares the two technologies, providing a short
description of how they work, areas in which they operate and cost-developments.
