We also learnt a few conversion rates between sources of energy and kWh: 1 ton of coal = 8141 kWh, 100 mW = 100000 kWh = 12.28 tons of coal, 5000 mW = 614.18 tons of coal, and 1 gallon of gas = 35 kWh. Since we learnt that a generator produces 2000 mW of energy per hour, we found out use 5000 mW of energy to create 2000 mW of electricity per hour. Based on this data, we can calculate how much coal will be needed to power our houses per month and per year. We also learnt that one train carries approximately 15,000 tons of coal. This means that nearly one full train’s worth of coal is used every day by a single generator (24*614.18 = 14740.32). And if not coal, then the generator is using natural gas or nuclear energy. While we may have thought that a house would obviously use more energy than a car, we were completely wrong. Since 1 gallon of gas creates 35 kWh of energy, cars use about 525 kWh of energy per week. In comparison, the average house uses 600-700 kWh of energy in a month. This means that one car uses about 4 times as much energy as a house. We also learnt how much electricity is used by many products that we use in our everyday life.(i.e. Laptop, TV, and convection oven). The most astounding one was the Oven which used 533 Watts, then came the tv with 166 Watts, and last came the laptop which used 69 Watts.
