Reducing global warming
Biology · Secondary 3 · Medium · Reducing global warming
A school replaces all its old fluorescent lights with LED lights that use half as much electricity for the same brightness. How does this action help reduce global warming?
- Less electricity is used so less fossil fuel is burned, releasing less carbon dioxide.
- LED lights absorb all the carbon dioxide in the classroom air.
- LED lights reflect more sunlight back into space than other bulbs.
- Less heat is produced in the room, so the greenhouse effect in the atmosphere stops.
