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:
What are some disadvantages of fossil fuels?
~ Fossil fuels can be dangerous to both our personal health and the health of the environment. The burning of fossil fuels results in the release of various gases that can have harmful effects on the respiratory tracts of humans and animals. It also increases the amount of dangerous greenhouse gases in the atmosphere.
How does nuclear energy work?
~ Nuclear energy is based on the concept of harvesting energy from nuclear reactions. In such reactions, atoms with heavy nuclei are smashed into atoms with lighter nuclei. The resulting reaction yields a tremendous amount of energy.
What are the advantages and disadvantages of hydropower?
~ Hydroelectric power plants do not produce harmful environmental waste and do not cause air pollution; however; hydroelectric dams can disturb the ecosystems of the rivers where they are constructed. These disturbances can have serious environmental consequences.
How is energy harvested from the wind?
~ Wind energy is harvested through the use of wind turbines or windmills that can generate electricity using the force of the wind.
What is a disadvantage of using wind?
~ The disadvantage of wind energy is that windy places are needed for windmills to produce energy.
