Solar energy is inexpensive compared to using fossil fuels. But...does solar energy have the same energy yield (amount of energy released) as the use of fossil fuels?
What are the different types of renewable and nonrenewable energy sources anyway? Do some give off more energy compared to others? What are the positive and negative effects of each?
I recently did an internship at an oil company over the summer and put together this assignment that will get students to think about what types of energy is used around the world and what type of yield each produces.
To really hit home the concepts, I also put together a crossword puzzle and a word search. Students use the information on the renewable and nonrenewable hand-outs to find the answers for these puzzles.
For those who want to take this assignment one step forward...have students build a hydroelectric power plant or a wind turbine to harvest energy. For this I purchased supplies from the NEED Project which can be found at NEED.org. I also purchased some voltmeters to measure voltage.
I also put together a PowerPoint on Renewable & Nonrenewable Energy which shows students what these different types of resources look like in the real world. This PowerPoint can be found on teacherspayteachers.com.
