This video is one of a series from the Switch Energy project. It reviews the environmental impacts of various energy resources including fossil fuels, nuclear, and renewables. CO2 emissions as a specific environmental impact are discussed.

This is a series of 10 short videos, hosted by the National Science Foundation, each featuring scientists, research, and green technologies. The overall goal of this series is to encourage people to ask questions and look beyond fossil fuels for innovative solutions to our ever-growing energy needs.

In this activity, students calculate electricity use by state and determine, using Google Earth, how much land would be required to replace all sources of electricity with solar panels.

This online activity challenges students to design a renewable energy system for one of five different cities, each with different energy resource potential and budgets. Students can test their designs using real-time weather data in each city.

This introductory video summarizes the process of generating solar electricity from photovoltaic and concentrating (thermal) solar power technologies.

In this activity, students use Google Earth to investigate a variety of renewable energy sources and select sites within the United States that would be appropriate for projects based on those sources.

Students investigate passive solar building design with a focus on heating. Insulation, window placement, thermal mass, surface colors, and site orientation are addressed in the background materials and design preparation. Students test their projects for thermal gains and losses during a simulated day and night then compare designs with other teams for suggestions for improvements.

This video, from the US Department of Energy, shows the basics of how a PV panel converts light radiated from the sun into usable power, whether on the electric grid or off, and without emissions or the use of fossil fuels.

This is a team-based activity that teaches students about the scale of the greenhouse gas problem and the technologies that already exist which can dramatically reduce carbon emissions. Students select carbon-cutting strategies to construct a carbon mitigation profile, filling in the wedges of a climate stabilization triangle.

In this activity, students play the role of energy consultants to a CEO, assessing and documenting the feasibility, cost, and environmental impact of installing solar power on 4 company facilities with the same design but in different geographical locations.
