The average human uses approximately 2,000 calories (kcal) each day in food resources. This is roughly equal to a little more than 2 kWh – or the amount of energy (electricity) that it takes to light a 60 Watt bulb for 30 hours. Pretty amazing huh!? The amount of energy our bodies consume pales in comparison to the energy we use to power our appliances, heat or cool our homes, or provide us with the everyday comforts we take for granted. If the energy we used to power our technologies were instead utilized by our bodies, how long would it provide us with energy? Take this quiz to find out!
