The difference between photovoltaic and solar-thermal isn't the type of produced energy. In both cases it is electric energy, but via different physical ways. photovoltaic - http://en.wikipedia.org/wiki/Photovoltaic_system solar-thermal - http://en.wikipedia.org/wiki/Solar_power_tower ... - http://en.wikipedia.org/wiki/Solar_updraft_tower ... - http://en.wikipedia.org/wiki/Energy_tower_%28downdraft%29 But it would be good to propose a tag for heat plants or smaller block heating stations.
