Forestimated world energy consumption was 5.
Context Students will use Internet resources to investigate and compare alternative sources of energy. It is presumed that students have some basic prior understanding of the concept of energy. This investigation uses many resources from Energy Quest, an Educational Supersite.
The recommended readings and activities in this investigation would be most appropriate for fourth or fifth grade students.
However, this site provides ample resources for adapting the lesson to a wide variety of reading levels.
You may wish to preview The Energy Story prior to introducing these activities, to gather background information on energy resources and to identify the most appropriate resources for your students.
Motivation To introduce this activity, students should use their Energy Sources and Use student esheet to go to and read Energy Story: Introduction on the Energy Quest website.
This page introduces students to the concept of energy, and the importance of using energy resources wisely. The introduction includes a list of the energy resources.
Ask students which resources they have heard of, which are used in their homes, and which are used in school. Tell students that they will be energy-nauts for their own community. They will research to find the theory, applications, environmental impact, and cost related to a specific energy resource.
Each group will present its findings and the class will attempt to reach a consensus on the most practical source s of energy for the community. Development In this part of the lesson, students will learn more about energy sources, including renewable energy sources.
To begin, student should use their student esheet to go to and read Fossil Fuels. Once they are done reading the resource, ask students: What are the major forms of fossil fuels?
How were fossil fuels formed? How are these fuels collected? What are the advantages and disadvantages of using fossil fuels? They should scroll down the page to read: What are the environmental benefits of renewable energy?
How much would it cost a household to do renewable energy? These reports are somewhat sophisticated, but clearly and concisely present the case for utilizing renewable energy technologies.
After students read these reports, they should write down their answers to these questions on their student sheet: Why do these reports suggest that communities should begin to look at alternative energy resources?
What are the benefits of using renewable energy technologies? Why aren't some renewable resources widely accepted today?
Which energy resource is cheaper in the short run? In the long run? What is meant by the terms "environmental costs" and "social costs"? What are some examples of each?In this video lesson you will understand how water can be used to generate electrical energy.
You will also identify some benefits and drawbacks of using this type of renewable resource for energy. While advantages and disadvantages of renewable energy exist, the advantages to using renewable forms of energy far outweigh the disadvantages, more so moving to the future.
Advantages of Renewable Energy. Renewable energy is eco-friendly; It is a clean source of energy, meaning, it has low or zero carbon and greenhouse emission. A Brief History of Power Use The sun is by far the oldest source of energy.
It has provided heat and light for millions of years and is directly responsible for sustaining all life on earth. U.S. Department of Energy (DOE) by the National Renewable Energy Laboratory (NREL),a DOE national laboratory,defined renewable power “Renewable energy systems use resources that are constantly replaced and are usually less polluting.
Examples of renewable energy systems include solar, wind, and geothermal energy (getting energy from the heat in the earth). Cobb EMC members and utility customers around the country should be aware of telephone, mail, email, door-to-door, and other in-person scams.
