Much of the energy produced is lost before it can become useful. Explain how energy efficiency and the second law of thermodynamics may be useful in a discussion with another person on how to reduce CO2 and other greenhouse gas emissions.
What will be an ideal response?
Machines that use fossil fuels are very energy-inefficient, converting a small percentage of the energy in the fuel source to useful activities. An effort to increase the level of efficiency would substantially reduce the amount of fossil fuel that needed to be converted and would reduce the amount of emissions of CO2 and other greenhouse gases.
