We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy.
When we burn fossil fuels, burn wood for heat, and use electricity, we are using energy. Other sources of energy include âclean or renewable energy,â such as bioenergy, geothermal energy, run-of-the-river, solar energy and wind power.hen we burn fossil fuels, burn wood for heat, and use electricity, we are using energy.
