Students investigate how much greenhouse gas (carbon dioxide and methane) their family releases into the atmosphere each year and relate it to climate change. To address this, students use the Environmental Protection Agency's Personal Emissions Calculator to estimate their family's greenhouse gas emissions and to think about how their family could reduce those emissions.

This video explains what is involved in conducting a home energy audit. Such an audit evaluates how much energy you use in your house and suggests the most cost-effective measures you can take to improve the energy efficiency of your home. The outcomes are the use of less energy resulting in cost-savings on your energy bills.

This video segment from What's Up in the Environment shares how an entire home can be constructed using green energy sources (solar and geothermal energy). Video is narrated by young boy whose father is the chief engineer on the project.

This short video touches briefly on the future of global energy and which energy sources best meet four energy-choice criteria: affordable, available, reliable, and clean.

This video is a short segment from NOVA's 2007 Saved by the Sun video. It features a new solar technology -- fabricating solar paint -- being developed to make solar electricity more affordable.

This video is one of a series produced by the Switch Energy project. It reviews the pros and cons of natural gas as a source of energy.

This short video reviews how nations and individuals on Earth can work together to reduce the emission of CO2. It discusses strategies to reduce greenhouse gas emissions (energy conservation, renewable energies, change in energy use) and the role that government can play in this process.

This video highlights the benefits of electric vehicles, including improved fuel efficiency, reduced emissions, and lower maintenance costs.

This short video makes the case that rapid climate change affects the whole planet, but individuals can make a difference and make their carbon footprint smaller. Common suggestions are identified for young children to consciously consider what they can do.

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.
