- A video that starts a module about wind energy.
- Segment 9 directly feeds into segment 10 and is relevant to facilitate a discussion on renewable energy.
- See: http://earththeoperatorsmanual.com/for_educators
About the Science
- The statement that,"energy efficiency worldwide could reduce demand by fully one third by 2030" is debatable. Long-term energy demand actually increases with increased energy efficiency because energy efficient devices have more applications (Jevon's Paradox: http://www.eoearth.org/article/jevons_paradox).
- Numbers given are not cited, but it can be assumed that when presented by scientist Richard Alley, they are well researched.
- Discusses pros and cons of wind energy (emphasizing pros) and the need for continued research into renewables and energy efficient technology.
- The 2030 energy portfolio proposed is overly ambitious and would require an unlikely build-out of renewable energy infrastructure and technological development.
- Comments from expert scientist: Good overview and outlook. No major problems.
About the Pedagogy
- Shows how wind is a potential energy resource in West Texas, which sits at the southern end of the US wind corridor.
- Talks about how "green energy" translates to economic gains for some stakeholders in communities.
- An annotated script, learning objectives, vocabulary, and teaching tips are provided.

Disciplinary Core Ideas: 4
MS-PS3.A1:Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed.
MS-PS3.A2:A system of objects may also contain stored (potential) energy, depending on their relative positions.
MS-PS3.B1:When the motion energy of an object changes, there is inevitably some other change in energy at the same time.
MS-ESS3.A1:Humans depend on Earth’s land, ocean, atmosphere, and biosphere for many different resources. Minerals, fresh water, and biosphere resources are limited, and many are not renewable or replaceable over human lifetimes. These resources are distributed unevenly around the planet as a result of past geologic processes.
Disciplinary Core Ideas: 7
HS-PS3.A1:Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system’s total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms.
HS-PS3.A2:At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy.
HS-PS3.B2:Energy cannot be created or destroyed, but it can be transported from one place to another and transferred between systems
HS-PS3.B3:Mathematical expressions, which quantify how the stored energy in a system depends on its configuration (e.g. relative positions of charged particles, compression of a spring) and how kinetic energy depends on mass and speed, allow the concept of conservation of energy to be used to predict and describe system behavior.
HS-PS3.B4:The availability of energy limits what can occur in any system.
HS-PS3.D1:Although energy cannot be destroyed, it can be converted to less useful forms—for example, to thermal energy in the surrounding environment.
HS-ESS3.A2:All forms of energy production and other resource extraction have associated economic, social, environmental, and geopolitical costs and risks as well as benefits. New technologies and social regulations can change the balance of these factors.
Cross Cutting Concepts: 2
HS-C5.2:Changes of energy and matter in a system can be described in terms of energy and matter flows into, out of, and within that system.
HS-C5.3:Energy cannot be created or destroyed—only moves between one place and another place, between objects and/or fields, or between systems.
