Producing energy — fuels, cells & clean energy
Narrated lesson · press play
Where does our energy come from? Learn how burning fuels and nuclear isotopes make heat, how a simple cell turns chemistry into electricity, and how clean sources — solar cells and the hydrogen fuel cell — make power without the pollution.
What you'll learn in this lesson
By the end you should be able to (NSSCO Chemistry 6.3):
- Describe the production of heat energy by burning fuels
- Describe radioactive isotopes (e.g. U-235) as a source of energy
- Describe the production of electrical energy from simple cells (two electrodes in an electrolyte)
- Describe sources of clean energy
- State that electrical energy can be produced from sunlight using solar cells
- Describe the use of hydrogen as a fuel reacting with oxygen to generate electricity in a fuel cell
