This video segment, adapted from NOVA scienceNOW, addresses how new technology can help monitor and modernize the infrastructure of the U.S. power grid, which is ill-equipped to handle our increasing demand for electricity. Video provides a great overview of how electricity is generated and how the grid works.

This video introduces the concept of daylighting - the use of windows or skylights for natural lighting and temperature regulation - and how it is one building strategy that can save operating costs for homeowners and businesses.

This engaging video focuses on national and global wind energy potential by specifically highlighting Texas' role as wind energy leader and energy efficiency efforts in Houston, Texas.

This is a series of 10 short videos, hosted by 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 homework problem introduces students to Marcellus shale natural gas and how an unconventional reservoir rock can become an attractive hydrocarbon target. It is designed to expand students' understanding of hydrocarbon resources by introducing an unconventional natural gas play. Students explore the technological factors that make conventional source rocks attractive reservoir rocks and how this advance impacts both U.S. energy supply and the environment.

This video segment is adapted from Building Big, a PBS series hosted by David Macaulay. It explores Hoover Dam's hydroelectric capabilities by explaining how it is able to harness the potential energy stored in the reservoir and convert it to electricity. It also discusses environmental impacts of the dam and others like it.

This video segment examines ethanol, a cleaner-burning fuel alternative to gasoline, and the efforts to produce it more efficiently.

This online calculator converts from one energy unit to another - from gallons to British thermal units (Btu), kilowatt/hours to megajoules, short tons to metric tons.

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

This Flash animation describes how hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.
