Light energy and heat energy
You can use energy to cook food, heat your home, and make your car work.
The primary use of geothermal energy is in the agricultural industry. This type of energy is the primary source of heat in greenhouses.
LED light bulbs are the most energy-efficient for home use.
Incandescent lights also produce heat energy as a byproduct of their operation. This heat energy is often an inefficient use of the electricity powering the light bulb.
My main source of energy at home is from natural gas
Hydroelectric power (from a dam), nuclear energy, solar power and wind power generate electricity. Natural gas is used for heating. Solar (the sun) can produce heat and electricity.
The kettle uses heat energy. Depending on your type of stove, that heat will usually come from chemical energy (in a gas stove), or electrical energy (in an electrical stove).
Hair straighteners typically use electrical energy, which is converted into heat energy to style the hair by passing it through heated plates.
Use energy star ated appliances. Turn your heat down at night.
A kettle uses electrical energy and converts it into heat energy.
