What is energy quality? Distinguish between high-quality energy and low-quality energy and give an example of each. What is the first law of thermodynamics (law of conservation of energy) and why is it important? What is the second law of thermodynamics and why is it important? Explain why the second law means that we can never recycle or reuse high-quality energy. What is energy efficiency? What percentage of the commercial energy used in the United States is unnecessarily wasted? Why is it important to reduce this waste and how can we do this?
