But this enormous temperature is not just because Venus is closer to the Sun than we are. In fact, about two thirds of the energy of the Sun is absorbed by the clouds, and only one third of the heat energy reaches the ground. In fact less solar energy reaches the ground on Venus than on Earth. The reason that Venus is so hot is because of a massive runaway Greenhouse effect. Any heat that does get inside the clouds is trapped there.
Lightning seems to be as common on Venus as it is on Earth.
Most of the lightning happens within the thick high cloud deck. Venus rotates very slowly. The clouds on Venus race around the planet some 60 times faster than the surface. They do a complete circle every 4 Earth days so the clouds pass through the planet's afternoon on roughly the same time scale as the clouds do on Earth. And just like on Earth, the thunderstorms and lightning on Venus seem to happen mostly in the afternoon and at dusk.
