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.
The energy stored in the soil will radiate out to warm the air, raising air temperatures. 2. Energy in the form of heat, electricity, motion, or sound can change forms and move from one system to another. This can be demonstrated by making a cup of tea. For example, electricity, one form of energy, changes form to thermal energy (heat) through the stove and it transferred by conduction to the water for tea. The cup warms the hands, and the tea warms the insides of the person drinking the tea. This is energy transfer.
