There is abundant energy in space. Even though most of deep space (the vast stretches of empty area between planets, stars and moons) is cold and dark, space is flooded constantly by electromagnetic energy. All stars in the universe produce energy and send it out into space. Planets, asteroids and moons reflect that energy back, glowing in the darkness. They can also release energy themselves in the form of heat from volcanoes or other processes. Virtually everything in space is in motion, so there is also kinetic or motion energy in space.
