        Turning Wasted Heat Into Power

        With this lesson, teach about energy transfer, conversion, and efficiency. The mechanical energy of turbines in power plants works to produce electrical energy for the power grid. But, it’s not very efficient – a lot of energy is lost when we burn fossil fuels to make electricity. Would it be possible to somehow recycle the wasted heat from that conversion for other uses? There’s a name for that (two, actually): co-generation, or CHP (combined heat and power). This story and lesson were the result of a curiosity of an 8th grade student, who asked Inside Energy a question and then helped us research and report the answer. His question was: Would it be possible to make a power plant someday that doesn’t lose any energy?
