The ENIAC used a lot of power. It took up a ton of space and weighed 30 tons. The ENIAC was created to help win the war. It helped to calculate things including the angle of the guns, wind speed, direction of wind, temperature and humidity. The main component of the ENIAC was the vacuum tubes. Originally the tubes were switches but they switched to vacuum tubes. These tubes kept the ENIAC running. They were quiet and fast. The ENIAC was finally shut down on October 2, 1955.
