Energy chains: energy use

Select energy sources and energy converters to build energy chains to power appliances and vehicles. Examine how each energy converter in a chain loses some energy and reduces the energy available for use. For example, show that using a solar panel and an electric motor to drive a car delivers only 16% of the original ...
