【PTE干货】PTE 高频summarize spoken test精析 （十：Light bulb）
This is a 40 watt light bulb. If you leave it on all the time, it uses a kilowatt hours of power every day. And it is possible to use that to measure all forms of power consumption using this unit of light bulb. I started measuring everything around my house, around my office and I found some surprising things. First I plugged in a phone charger. It didn’t even register on this calorimeter. It used 100 of light bulbs worth of power. I don’t think the phone charger is gonna be our number 1 form of energy consumption. Just taking one hot bath every day uses the same energy, same power of 5 light bulbs all the time nonstop. And I have been using steadily about 40 light bulbs worth of gas for heating, making hot air, hot water and that surprised me. Transport is one of the biggest forms of energy consumption. It uses about a third of our energy. If you drive an average car 50 km a day, that corresponds to 40 light bulbs on all the time.

This lecture introduces using light bulb to measure all other forms of power consumption.
The speakers started measuring the power consumption around his house, office and he found something surprising. The phone charger is his number 1 form of energy consumption, which used 100 light bulbs worth of power. Other activities such as heating, making hot air, hot water used 40 light bulbs worth of power steadily every day.
In addition, transport is one of the major energy consumption activity, which consumes 40 light bulbs of energy each day if you drive 50 kilometers.
