"Energy" Energy and Sustainable Development PPT Teaching Courseware

Part One: Guidance Design

Learning point 1: The history of human energy utilization

Question 1: Humanity’s earliest “technical revolution” was ___________; the invention of __________ was a new milestone in human energy utilization; the invention of ____________ kicked off the use of new energy represented by nuclear energy.

Question 2: The coal, oil, and natural gas we use today were formed from animals and plants buried underground millions of years ago over a long period of geological time, so they are called __________. Energy that can be obtained directly from nature, such as __________, is called ____________; energy that cannot be obtained directly from nature and must be obtained by consuming _________ is called _________, such as electricity, gas, etc.

Learning Point 2 Energy Crisis

Question: For more than two centuries, human energy consumption has increased dramatically (as shown in Figure 22-1-2). Combining the energy sources you know in life, think about whether there is an energy crisis in our country? What should we do in real life?

[Answer] There is an energy crisis. We must save energy at all times in our lives, such as cherishing every drop of water and turning off water pipes and lights in time.

Energy PPT, Part 2: Summary of Frequent Examinations

Type 1 Understanding of Energy

Example 1 Regarding energy, which of the following statements is correct ()

A. energy is energy

B． Air and chemical energy are energy sources

C. Gasoline and coal are both energy sources

D． Chemical fertilizers and sunlight are energy sources

Type 2 Energy Classification

Typical Example 2 (Multiple Choice) Energy provided in ready-made form in nature is called primary energy, and energy that needs to be indirectly produced by relying on other energy sources is called secondary energy. For example, hydrogen is an efficient and non-polluting secondary energy because Very little hydrogen is readily available in nature. Which of the following statements is correct ()

A. Natural gas is a first-class energy source B. Carbon monoxide is a secondary energy source

C. The electricity used by household appliances is a first-class energy source

D． Wind energy is a secondary energy source

[Explanation by Famous Teachers] Primary energy and secondary energy have the same meaning as primary energy and secondary energy, but they have different meanings. Questions like this only need to be compared based on the meaning of the question when reviewing the question.

Type 3 Energy Trends

Example 3 "Energy crisis" is a common problem faced by all countries in the world today. In this regard, the following measures are feasible ()

A. Everyone must consciously save water and electricity

B． Closure of existing thermal power stations

C. Hydro and wind power stations are to be built everywhere

D． Stop using petroleum resources and replace them with nuclear and solar energy

Energy PPT, Part 3: Class Feedback

1. Among the following examples, the ones that are not energy sources are ()

A. Coal b. Geothermal

C. Diesel engine D. Alcohol

2. Some energy can be obtained directly from nature, which is called primary energy; some energy cannot be obtained directly from nature, and this type of energy is called secondary energy. The following are secondary energy sources: ()

A. Coal b. oil

C. natural gas d. Electric energy

3． Among the following energy sources, the one that belongs to fossil energy is ()

A. Nuclear energy, biomass energy, hydro energy

B． Electric energy, gasoline, diesel

C. Solar energy, geothermal energy, wind energy

D． Coal, oil, natural gas

4. (Multiple choice) Which of the following statements is incorrect ()

A. The reserves of primary energy are limited, so we must use energy rationally

B． The coal gas and liquefied gas burned by urban residents are secondary energy sources.

C. The key to solving energy problems is to improve energy utilization

D． The development and utilization of new energy, especially nuclear energy and solar energy, is the main way to solve the energy problem

5. Among energy sources such as tidal energy, nuclear energy, gasoline, and solar energy, the secondary energy is _________, and the new energy is __________________.

6. There are three energy revolutions in human history: the first energy revolution, marked by __________, led to the era of using firewood as the main energy source; the second energy revolution, marked by the invention of __________, led to the era of human The main energy source has changed from firewood energy to fossil energy; the third energy revolution, marked by the invention of __________, has promoted nuclear energy to become a conventional energy source in many economically developed countries.

7. Hydropower, thermal power and nuclear power are currently the main ways for people to obtain electrical energy. Among them, ________ power generation is likely to produce the greenhouse effect, and water energy is a ________ secondary energy source.

8. Figure 17-1 shows the image of "human energy consumption over more than two centuries." In response to this trend, we should ____________________.
