collaborative inquiry

1. Our lives require energy

In these production and life, energy is consumed. Where does this energy come from?

3. Conventional energy

Solar energy Fossil energy Wind energy

Hydro energy Geothermal energy

4. What other energy sources do you know?

Tidal energy Nuclear energy Biogas

5. Where does the electricity in our lives come from?

The electrical energy in our lives is generated by generators. Generators convert wind energy, water energy, solar energy, geothermal energy, nuclear energy, etc. into electrical energy, which is transported to thousands of households through wires, and then converted into other forms of energy such as light energy, internal energy, and mechanical energy.

6. What are the advantages of using electrical energy?

Easy to transport and transform

instant practice

1. The various forms of energy are listed below: firewood, coal, oil, natural gas, wind energy, water energy, electric energy, solar energy, and geothermal energy. Which of these energy sources are fossil energy? What are primary energy sources? What are secondary energy sources? Please fill in the form below.

2. What significance does the invention of the steam engine have on mankind’s use of energy? What significance does the widespread use of electrical energy have on human energy use?

The invention of the steam engine was a new milestone in mankind's use of energy. Since then, humans have gradually replaced human and animal power with mechanical power, and the main energy source of humans has shifted from firewood to coal.

Electric energy is easy to transport and transform. We can easily convert other forms of energy into electrical energy, transport it to thousands of households through transmission lines, and then convert it into other forms of energy in electrical appliances.
