How is Power Generated?

Power generation makes modern human societies thrive. The method of generation is dependent on the availability of resources, technology, as well as the ability to deliver energy where it is needed. The video below summarizes some of the basic ways electricity is generated and delivered to our homes.

 

Exercise 1 – Energy

Watch the video above before answering the questions below:

  1. List the main fuel types used to generate energy.
  2. How is electricity delivered from the source of generation to where you use it?
  3. According to the pie chart shown on global energy production, what are the three largest sources of energy?
  4. Which of the following is a renewable source of energy?
  5. Most methods of generating power involve creating steam. T/F
  6. What types of fuels are typically used for generating steam?
  7. What is the main problem with using fossil fuels in power generation?
  8. What portion of the world’s greenhouse gas production is caused by electricity generation?
  9. Identify three ways steam can be generated without the use of fossil fuels.
  10. Steam turbines can generate electricity. Identify two ways that turbines can generate electricity without the use of steam.
  11. Which renewable source of energy is the fastest-growing source of energy?
  12. Can wind and solar power be generated on demand like traditional sources of power?
  13. Explain your previous answer.

Fossil Fuels

Fossil fuels powered modern human societies and have been crucial for their continuing growth. However, their unsustainable use has also caused numerous long-term problems that threaten the viability of life on Earth. Use the resources below to learn about fossil fuels.

 

 

Exercise 2 – Fossil Fuels

Use the resources below to answer the following questions:

  1. What is fossil fuel?
  2. List the three main types of fossil fuels.
  3. Fossil fuels are renewable resources of energy. T/F
  4. Explain the previous statement.
  5. What does carbon in fossil fuels converted to when these fuels are burned for energy production?
  6. How does the burning of fossil fuels impact climate change?

  4. Rock formations require high porosity and permeability for oil to be extracted. T/F
  5. How is the crude oil commonly extracted from the ground?
  6. What does an oil refinery do?
  7. List four products commonly produced from crude oil?
