According to this, the stars in the night sky have a cumulative magnitude of -6.5. This is very dim, so I expect the heat generated to be tiny, but I'm wondering how tiny.
Moonlight does measurably increase the Earth's temperature. According to this, the full moon heats the lower atmosphere by about 0.02°C, though a part of that difference may be from orbital effects.
