e. A combination of strategies is needed to reduce greenhouse gas emissions. The most immediate strategy is conservation of oil, gas, and coal, which we rely on as fuels for most of our transportation, heating, cooling, agriculture, and electricity. Short-term strategies involve switching from carbon-intensive to renewable energy sources, which also requires building new infrastructure for alternative energy sources. Long-term strategies involve innovative research and a fundamental change in the way humans use energy.

Students take a Home Energy Quiz from the Energy Star Program to identify home improvements that could make their homes more energy efficient. The resource includes follow-up information about energy-saving activities to reduce the cost of heating and cooling, supporting the student examination of energy use, energy efficiency and conservation.

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 is a laboratory activity in which students will compare the amount of carbon dioxide in four different sources of gas and determine the carbon dioxide contribution from automobiles. They test ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide from a vinegar/baking soda mixture.

An activity focusing on black carbon. This activity explores the impacts of the use of wood, dung, and charcoal for fuel, all which generate black carbon, in developing countries.

This lesson plan engages students in a real-life exploration of climate change as it is affected by greenhouse emissions from vehicles. The aim of this activity is for students to realize the impact of vehicle use in their family and to give students the opportunity to brainstorm viable alternatives to this use.

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

A sequence of five short animated videos that explain the properties of carbon in relationship to global warming, narrated by Robert Krulwich from NPR.

An attractive concept/mind map that illustrates various human strategies for responding to climate change. It was developed by a psychologist and not by an educator or scientist but can be used to inspire discussion and artistic representations of the human dimension to climate and energy issues.

This activity includes an assessment, analysis, and action tool that can be used by classrooms to promote understanding of how the complex current issues of energy, pollution, supply and consumption are not just global but also local issues.

This video segment explores whether, in principle, renewable energy resources could meet today's global energy needs of about 15.7 terawatts.
