Everything people do in their daily lives involves the consumption of resources—particularly energy. With respect to energy, electricity is one of the most important resources consumed and also one of the highest in demand. Traditionally, fossil fuels such as coal, natural gas, and oil have dominated the U.S. energy mix; however, as it is well-known, carbon-emitting energy sources are very detrimental to the environment and are contributing to global warming. Fortunately, alternative energy resources such as solar, wind, hydro, and geothermal power are becoming more efficient and prevalent in today’s energy economy.

What would cause the calorimeter efficiency to be less than 100%? Provide at least two possible causes.
