Question

We mentioned earlier in the course that energy technologies in developing countries often have much lower efficacies than those in developed countries. Let’s look at one example, lighting via kerosene lamps, which are common in developing countries but about 150x less effective than incandescent lightbulbs at turning energy into useful light. If a family wanted just one tenth of the light provided by the 75 W lightbulb, they’d need to consume 15x as much power, or 1125 W. If a family ran 1125 W worth of kerosene lamps for just 2 hours each day, how much CO₂ would this emit? You may assume that kerosene produces the same emissions as gasoline

Hint (1 of 1): You will need to look up the emissions factors for natural gas and gasoline. Depending on the units you find, you may need to look up other values as well, such as the energy density of natural gas
