Energy Conservation: Considering Sources, Cost and Impact
Wind, biomass and solar energy are examples of renewable sources of energy utilized around the world.Copyright 2005 Jürgen from Sandesneben, Germany, Wikimedia Commons https://commons.wikimedia.org/wiki/File:Alternative_Energies.jpg
Students are introduced to the idea that energy use impacts the environment and our wallets. They discuss different types of renewable and nonrenewable energy sources, as well as the impacts of energy consumption. Through a series of activities, students understand how they use energy and how it is transformed from one type to another. They learn innovative ways engineers conserve energy and how energy can be conserved in their homes.
We use energy every day. Engineers consider the effects of this energy use on our environment and are developing alternative energy sources and ways to conserve energy. Solar and wind power are two forms of energy developed by engineers that have a very small impact on the environment. The development of compact fluorescent light bulbs and better insulation for our homes are two ways engineers are helping us conserve energy.
After this lesson, students should be able to:
- Define and describe renewable energy.
- Explain that energy in its various forms can affect everyday objects and is involved in everyday events.
- List several ways to conserve energy.
