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

This video addresses the importance of efficiency in providing power to an increasingly large global population.

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 is essentially an infomercial about electric cars - components, challenges, benefits - narrated by Antonio Neves of the.News and featuring various members of the auto industry.

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 video illustrates the advantages of woody biomass as a renewable, carbon-neutral energy source. Woody biomass is underutilized and often overlooked as a renewable fuel, and it can be harvested sustainably and burned cleanly.

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

This interactive addresses the question if we can reduce CO2 emissions by 20% of 1990 levels and help avoid dangerous climate change? Users of this interactive can manipulate changes to various sources and uses (supply and demand) of energy with the goal of reducing C02 emissions in Great Britain by 80% in the year 2050.

This animated slideshow introduces biodiesel as a fuel alternative. With concern about the use of petroleum-based fuels at an all-time high, biodiesel is experiencing a popularity surge. And algaeâotherwise known to some as pond scumâ are grabbing headlines as the next potential biodiesel superstar. But how and why do algae make oil? And why do they make so much of it? In this audio slide show, U.C. Berkeley's Kris Niyogi describes the process and its potential.

In this activity students make biodiesel from waste vegetable oil and develop a presentation based on their lab experience. Parts of the activity include creation of bio-diesel from clean vegetable oil, creation of bio-diesel from waste vegetable oil, chemical analysis of biodiesel, purification of biodiesel, and creation of soap from glycerin.
