How do we use energy in our daily lives?
Energy use is all around us. Here are just a few examples of how we use energy daily:
- Chemical energy is used to heat buildings, cook food and power our vehicles. Our bodies use the chemical energy in food to fuel our daily activities.
- Light energy from the sun is needed for all living things on Earth. Light energy (artificial light) enables us to see when it is dark.
- Both thermal and electrical energy can be used to power our stoves and our heating systems.
- Electrical energy powers most devices and appliances in our homes, schools and where we work.
- All forms of electrical energy generation (except solar) use the magnetic energy of an electromagnet to generate electricity.
- When you are perched at the top of a ski run, ready to move, you have gravitational energy which transforms into the energy of motion (kinetic) when you push off.
