An interactive graph that predicts how many years until more than two dozen natural resources (e.g., chromium, oil, tin, coal, etc.) are depleted, based on current production rates or production that grows each year. Use the slider at...

Find out what renewable energy is and the role it plays in meeting energy needs. Renewable energy sources include biomass, hydropower, geothermal, wind, and solar.

Learn about renewable energy sources including biomass, which includes biofuels, hydropower, geothermal, wind, and solar.

Discusses how the the natural resources of the world are being depleted at an alarming rate, and that humans depend on them for their survival. Elaborates on four main causes of resource depletion, and initiatives that could help to...

With this resource, users join investigators in the exploration of humans' use of and dependence on the many energy resources. Learn about new technologies such as carbon capture and sequestration as an alternative to reduce our carbon...

This is a resource on solar energy, photovoltaic energy, solar thermal heat, solar thermal power plants and other forms of energy.

An approval from the U.S. Energy Department will financially allow further development and testing of low-carbon fuel.

One major advantage with the use of renewable energy is that as it is renewable it is therefore sustainable and so will never run out. Renewable energy facilities generally require less maintenance than traditional generators. Their fuel...

The Mackenzie Valley,in the Canada's Northwest Territories, is under the protection of WWF-Canada's Mackenzie River Basin Conservation Program. The program aims to protect habitats & ecosystems within the watershed, and to make sure...

Hydropower is a clean, renewable and reliable energy source which converts kinetic energy from falling water into electricity, without consuming more water than is produced by nature. Quite simply the oldest method by which renewable...

In this activity, students will use cookies to simulate the distribution of our nonrenewable resources (energy). Then, they will discuss how the world's growing population affects the fairness and effectiveness of this distribution of...

What factors are important to consider in order to make informed energy decisions? In this interactive, you select one of three locations and the energy resources and then try to provide 100% of that community's electricity needs while...

The many sources of energy production in the United States are described in this overview. Included are traditional sources, renewable sources, and new energy production technologies.

Description of how hydrokinetic power works including resource, conversion, and environmental issues.

Students consider the impact and sustainability of use of different biofuels on the economy, the environment, and society. Students also learn about bioelectricity and how converting biomass to electricity may be the more efficient way...

This lesson focuses on the scarce and non-renewable nature of fossil fuels in order to stimulate student thinking about energy conservation. It emphasizes the fact that saving energy can be good for the wallet as well as the earth's...

Major issue--the energy sources currently available to the world all have major drawbacks in the long term. Oil is efficient but leads to climate change. Coal is plentiful but polluting. Solar energy is appealing but only as dependable...

In this intimate talk filmed at TED's offices, energy innovator Amory Lovins shows how to get the US off oil and coal by 2050, $5 trillion cheaper, with no Act of Congress, led by business for profit. The key is integrating all four...

Robots are now being used to fight climate change and protect our green environments. They help to fight forest fires, manage our waste, restore the oceans, support renewable energy initiatives, and make agriculture more-environmentally...

Basic information about how these heat pumps function and where they can be used.

Discover the science concepts behind wind turbines and wind energy.

Learn about the efficiency behind wind energy, and understand how scientists look at the issue of power generation efficiency.
