Earth & Space Science
You will get to learn about natural resources by focusing on renewable and nonrenewable sources of energy. To test your understanding, you will then be responsible for meeting the energy needs of a small island.
After completing this tutorial, you will be able to complete the following:
How is biomass energy produced?
~ Biomass energy is produced through the burning of natural materials such as wood, sugar beets, corn, sugarcane, grains, compost, and manure.
What are the advantages and disadvantages with biomass energy?
~ Biomass is a renewable form of energy and derived from plant and animal resources-in short, resources that are replaceable. Also, biomass energy generally does not produce high levels of pollution. There are two major problems with using biomass energy. First, because most of the materials used to produce biomass energy are the products of grown plants, we often have to wait a significant amount of time for the plants in question to fully mature before they can be used. Second, a very large amount of land is required to grow these materials. Also, when biomass energy is burned, it gives out carbon dioxide, like fossil fuels.
What is geothermal energy, and why is it considered renewable?
~ Geothermal energy is a type of energy that comes from the heat of the Earth. It is considered renewable because, since there is always heat inside the Earth, we never run out of it.
What are the advantages and disadvantages of solar energy?
~ Solar energy is pollution free and available as long as the sun shines. Also, it produces energy inexpensively after the solar panels are set up. Besides that, there are minus sides. Solar energy is most practical in sunny areas and setting up solar panels and solar cells can be expensive.
