Description

"Developing New Energy" Energy and Energy Conservation Law PPT Courseware 2

Looking at the following three materials, what do you want to say?

1. Energy consumption in my country and the world

2. my country’s energy structure

3. According to statistics from the International Energy Agency, the oil, natural gas, and coal on the earth can be exploited by humans for only 40 years, 50 years, and 240 years respectively.

Development of new energy

1. What other energy sources do you think or do you know that are worthy of human development?

2. Which new energy do you think has the most potential for development?

1. Solar energy

1. Can you talk about the characteristics of solar energy?

2. What are the main methods of utilizing solar energy at present?

2. Nuclear energy

---The huge energy contained inside the atomic nucleus

There are two ways to obtain nuclear energy

1. Nuclear fission-chain reaction:

A nuclear reaction in which heavier atomic nuclei fission into lighter atomic nuclei.

2. Fusion - Thermonuclear Reaction

At ultra-high temperatures, two lighter nuclei can be combined into one heavier nucleus.

3. Fusion is more powerful

Atomic bombs are made based on the principle of nuclear fission. It is the result of an uncontrollable chain reaction!

Peaceful uses of nuclear energy - Nuclear power plants

Thinking: How is energy transformed during the working process of a power station?

Nuclear energy→internal energy→mechanical energy→electric energy

1. Energy conversion:

2. my country’s first self-designed and built nuclear power plant: Qinshan Nuclear Power Plant

3. Existing problems: - Radioactive contamination
