This interactive diagram from the National Academy of Sciences shows how we rely on a variety of primary energy sources (solar, nuclear, hydro, wind, geothermal, natural gas, coal, biomass, oil) to supply energy to four end-use sectors (residential, commercial, industrial, and transportation). It also focuses on lost or degraded energy.

In this short activity, students or groups are tasked to make concept sketches that track the source of electrical power as far back as they can conceive. The concept sketches reveal students' prior conceptions of the power grid and energy mix, and lead naturally into a lesson or discussion about energy resources and power production.

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.

This visualization includes a series of flow charts showing the relative size of primary energy resources and end uses in the United States for the years 2008-2012.

This activity is a learning game in which student teams are each assigned a different energy source. Working cooperatively, students use their reading, brainstorming, and organizational skills to hide the identity of their team's energy source while trying to guess which energy sources the other teams represent.

This activity comes at the beginning of a sequence of activities in an energy module. Students observe the transfer of solar energy to different appliances with a solar cell and then they investigate the effect of using different solar sources to supply energy to appliances.

This is a debate-style learning activity in which student teams learn about energy sources and are then assigned to represent the different energy sources. Working cooperatively, students develop arguments on the pros and cons of their source over the others.

In this activity, students explore real data about renewable energy potential in their state using a mapping tool developed by NREL (National Renewable Energy Laboratory) to investigate the best locations for wind energy, solar energy, hydropower, geothermal energy, and biomass.

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