Curious George - Season 4 Episode 16

It is the hottest day in the city and the city keeps suffering from blackouts. But there is one place left with electricity: the museum which just converted to being entirely powered by solar power. When George learns how the sun's light can be absorbed and turned into electricity, to do things like charge batteries, he tries to charge up several things at home such as his toy UFO or the cordless phone. But then he learns how solar power really works to make electricity. Then, when another blackout makes the Man unable to cook his lasagna for the museum's big power upgarde party, he and George learn that the sun's heat can also be used to cook things.
