This video and accompanying essay examine ways to reduce the environmental impact of burning coal. Two technologies are discussed: turning solid coal into a clean-burning fuel gas (syngas), and capture and storage of CO2.

In this interactive, students can investigate a typical hydrogen fuel cell prototype car from its fuel cell stacks to its ultracapacitor, a kind of supplementary power source.

The limited-production vehicle seen in this feature is a Honda 2005 FCX, which is typical of the kinds of hydrogen fuel cell cars that some major automakers are researching and developing.

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 PBS video shows how Klaus Lackner, a geophysicist at Columbia University, is trying to tackle the problem of rising atmospheric CO2 levels by using an idea inspired by his daughter's 8th-grade science fair project. The video examines the idea of pulling CO2 out of the atmosphere via a passive chemical process.

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

This is the ninth and final lesson in a series of lessons about climate change. This lesson focuses on the various activities that humans can do to mitigate the effects of climate change. This includes information on current and predicted CO2 emission scenarios across the globe, alternative energy sources, and how people are currently responding to climate change. Importantly, this lesson is motivating in showing students that they can make a difference.

In this activity, students take a Home Energy Quiz to identify improvements that could make their homes more energy-efficient.

One of a suite of online climate interactive simulations, this Greenhouse Gas Simulator uses the bathtub model to demonstrate how atmospheric concentrations of CO2 will continue to rise unless they are lowered to match the amount of CO2 that can be removed through natural processes.

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.

The video offers a simple and easy-to-understand overview of climate change. It poses basic questions such as 'What is it?' and 'How will it effect us?' and effectively answers those questions.
