ENERGY STAR-labeled computers use 30%-65% less energy than computers without this designation, depending on usage. Consider buying a laptop for your next computer upgrade; laptops use much less energy than desktop computers.
With an average temperature of minus 234 degrees Fahrenheit (minus 145 degrees Celsius), Jupiter is frigid even in its warmest weather. Unlike Earth, whose temperature varies as one moves closer to or farther from the equator, Jupiter's temperature depends more on height above the surface.
A star such as our own Sun can be much larger because it has a nuclear reaction generating energy at its center. The intensity of sunlight at Jupiter is about 1/25 of its intensity at Earth. Jupiter still retains heat at its center and its surface receives about as much heat from its interior as it does from the Sun. The surface temperature is - 234F.
