11.29 What is Energy Conservation?
Learn about energy conservation, what it means, and why conserving energy is a good practice. Discover how energy is used in the United States and how individuals can conserve energy in their daily lives.
Why Conserve Energy?
Look around the room right now. How many things can you see that use energy?
Your list might include:
- Computer
- Electric lights
- Fan
- Heater or air conditioner
- Clock
- Microwave
- Stove
Anything that plugs into the wall or runs on batteries uses energy. Other things that use energy include cars, factories, heaters, and air conditioners. People use a lot of energy every day! And we keep using more and more energy. If people keep using more and more energy, 20 years from now we’ll be using almost one and a half times as much energy as we are now, every day.
Using so much energy is a problem, because it’s hard on the planet. One big source of energy is oil, but using oil for energy makes a lot of dangerous smoke. The smoke from burning oil can make the air dirty and make people sick. Also, the way we get a lot of our coal and oil is by drilling for it. Drilling for coal and oil is hard on the land, the sea, and animals and people that live near the drilling.
If everyone used less energy, we could use less oil, and our air would be cleaner. That’s the point of energy conservation. The word ‘conservation’ means ‘saving.’Β Energy conservationΒ means saving energy, or not using more energy than you need. It doesn’t mean using no energy at all. It just means using less energy.
1. Main points:
Using energy, especially from sources like oil, is harmful to the environment and human health. Energy conservation, or using less energy, is important for a cleaner and healthier planet.
2. Questions:
- Content Analysis: What are some examples of items that use energy in our daily lives?
- Ideological Analysis: What does the text say is the reason for needing to conserve energy?
- Thematic Analysis: What is the central theme or topic of the text?
3. Further Discussion:
Can you think of a way you could use less energy in your daily life?
4. Answers:
- Content Analysis: Some examples of items that use energy include “computer, electric lights, fan, heater or air conditioner, clock, microwave, stove.”
- Ideological Analysis: The reason for needing to conserve energy is because it’s “hard on the planet” and using a lot of energy can “make the air dirty and make people sick.”
- Thematic Analysis: The central theme is the importance of energy conservation for the health of the planet and people.
Hey, future energy savers! πβ¨ Ever notice how many gadgets around you need power? Computers, lights, fans, you name it! But guess what? Using so much energy isn’t too friendly to our planet. π³π¦ You know what would be super cool? Using less energy! That’s what people call ‘energy conservation.’ π± So, how about it? Can you think of a way to be a little greener today? π
Energy Conservation: Big Picture
If we’re going to save energy, first we have to know how we use it. Let’s take a look at how we use energy in the United States. Out of every 100 units of energy:
- 22 are used in people’s houses
- 19 are used in commercial buildings like offices and stores
- 31 are used in factories and industry
- 28 are used for transportation, to fuel cars, trucks, and airplanes
 |
We can conserve energy used for all these things. For example, we can conserve energy in houses and offices by designing buildings so they stay warm better in the winter. Then, we don’t need to use as much energy for heating. We can conserve energy used for transportation by making new cars that don’t need as much fuel to run.
You probably aren’t building houses or cars yet, but you can still help. If you look at the chart, the places colored in blue are places where you can help conserve energy right now.
1. Main points:
Understanding how energy is used in different sectors like homes, commercial buildings, factories, and transportation can help us find ways to conserve energy effectively.
2. Questions:
- Content Analysis: What are the four main sectors where energy is used in the United States?
- Ideological Analysis: What does the text suggest as ways to conserve energy in houses and transportation?
- Socio-cultural Analysis: How does the text indicate that even someone who isn’t an adult can contribute to energy conservation?
3. Further Discussion:
What do you think is the most surprising way energy is used in the United States based on the information in the text?
4. Answers:
- Content Analysis: The four main sectors where energy is used in the United States are “people’s houses, commercial buildings like offices and stores, factories and industry, and transportation to fuel cars, trucks, and airplanes.”
- Ideological Analysis: To conserve energy in houses, the text suggests “designing buildings so they stay warm better in the winter,” and for transportation, “making new cars that don’t need as much fuel to run.”
- Socio-cultural Analysis: The text indicates that even someone who isn’t an adult can contribute by saying, “you can still help,” and mentioning “places where you can help conserve energy right now.”
Hey kids! π Ever wondered how we use energy in the U.S.? You’d be amazed! π π’ππ Let’s break it down: houses, offices, factories, and even cars use a chunk of energy. And guess what? We can save energy in all these places. Like making buildings that don’t need as much heating or cars that don’t guzzle as much fuel. π±π‘ Even if you’re not making cars or buildings yet, you can still help! π How cool is that? So, got any ideas on the most surprising way we use energy? π€
How You Can Conserve Energy
You can conserve energy in all kinds of ways. For example:
- Turn off the lights when you leave the room.
- Turn your heat down in the winter and put on a sweater instead.
- Turn your air conditioning down in the summer.
- Turn off your computer when you’re not using it.
- Take shorter showers. Heating water for a shower takes a lot of energy.
- Walk or ride your bike instead of asking your parents to drive you somewhere. This helps save energy on transportation.
1. Main points:
The text provides easy and practical tips for conserving energy in everyday life.
2. Questions:
- Content Analysis: What are some of the ways the text suggests you can save energy in your home?
- Thematic Analysis: What common theme underlies all the suggestions for conserving energy?
3. Further Discussion:
What’s one way you think you could conserve energy that wasn’t mentioned in the list?
4. Answers:
- Content Analysis: The text suggests you can save energy in your home by “Turning off the lights when you leave the room, turning your heat down in the winter and putting on a sweater instead, turning your air conditioning down in the summer, and turning off your computer when you’re not using it.”
- Thematic Analysis: The common theme underlying all the suggestions is making simple adjustments in everyday activities to conserve energy.
Hey there, future energy savers! π‘ So you wanna know how to be a superhero for the planet? π It’s super easy! Flip off the lights when you’re not in the room, wear a cozy sweater in winter instead of cranking up the heat, and maybe take shorter showersβyup, that hot water eats up energy! πΏ Even simple stuff like walking or biking instead of getting a car ride can make a difference! π΄ββοΈπ΄ββοΈ So what’s your super-secret tip for saving energy? π€« Got any genius ideas? π
Lesson Summary
Okay, let’s review what we’ve learned for a moment. We use energy every day to run our clocks, computers, and lights; to heat our houses; and to do all kinds of other things. The way we get energy is hard on the environment.Β Energy conservationΒ simply means using less energy. Energy conservation helps protect the environment. You can conserve energy by turning your heat and air conditioning down, taking shorter showers, and turning off anything that plugs in or uses batteries when you’re not using it. Walking or riding your bike will also conserve energy, because you won’t be using the fuel it takes to drive a car.
