Purpose: Universities and their actions affect the environment directly and significantly. Therefore, the carbon footprint (CF) needs to be implemented in these institutions for mitigating climate change and its potential risks. Based on this understanding, the university consortium quality and environment (QualEnv) stands out by its main…

This Article aims to share the results of a project that was developed with 80 students from Technical High School of Professional and Technological Education (PTE) at an institute located in the northeast of Brazil. The students discussed the global overview of fuel production and use, and how the introduction of green hydrogen into the market…

This activity is part of a larger set of activities and presentations developed by the Michigan Geographic Alliance to help teachers meet the proposed Social Studies standards in 6th and 7th grade. The Michigan Geographic Alliance website also has explanatory presentations, supplementary maps, and readings. In this 20-40 minute intermediate…

This 45 minute inquiry lesson can be used for a high school world geography or AP Human Geography course when the class discusses various issues regarding world energy resources. The lesson focuses on two particular issues: fossil fuel dependency and the growing energy demand. Students will examine the geographic distribution of current energy…

A television advertisement and a website present an interesting question: can rail company CSX "really" move a ton of freight 468 miles on a gallon of fuel, or is the claim preposterous? Let us examine the claim, first by understanding what is meant, looking at their data, and then converting units to examine the claim quantitatively.

This article is based on a case study that follows the trajectory of a technological device aimed at environmental education from the engineering laboratory in which it was designed into the contexts in which it is used. "Greendrive" is a driving simulator that accurately reproduces the performance of a vehicle in terms of fuel…

The purposes of this activity are to help middle school students understand the carbon cycle and realize how human activities affect the carbon cycle. This activity consists of two parts. The first part of the activity focuses on the carbon cycle, especially before the Industrial Revolution, while the second part of the activity focuses on how…

Providing sustainable mobility is a major challenge that will require new vehicle and fuel technologies. Alternative and future fuels are the subject of considerable research and public interest. A simple approach is presented that can be used in science education lectures at the high school or undergraduate level to provide students with an…

The standard for measuring fuel efficiency in the U.S. has been miles per gallon (mpg). However, the Environmental Protection Agency's (EPA) switch in rating fuel efficiency from miles per gallon to gallons per hundred miles with the 2013 model-year cars leads to interesting and relevant mathematics with real-world connections. By modeling…

Topics commonly taught in a general chemistry course can be used to calculate the quantity of carbon dioxide emitted into the atmosphere by various human activities. Each calculation begins with the balanced chemical equation for the reaction that produces the CO[subscript 2] gas. Stoichiometry, thermochemistry, the ideal gas law, and dimensional…

This article develops a broad sociological understanding of why biofuels lost out to leaded gasoline as the fuel par excellence of the twentieth century, while drawing comparisons with biofuels today. It begins by briefly discussing the fuel-scape in the United States in the late nineteenth and early twentieth centuries, examining the farm…

Natural gas production in Wyoming is a lucrative and influential industry. All the perks--jobs, education spending, the budget surplus--are huge incentives for communities and the fossil fuel-friendly state legislature to play along, to stay silent. And many are willing. There has been natural gas production in the state for almost a century, but…

As the United States strives to achieve energy independence, students need to be literate about energy and environmental issues. In this article, the authors present a lesson about the nation's electricity resources that is part 1 of a free, comprehensive unit on coal and energy that is available online (http://tinyurl.com/coalenergyunit). The…

In general terms there are only three primary energy sources: fossil fuels, renewable energy, and nuclear fission. For fueling road transportation, there has been much speculation about the use of hydrogen as an energy carrier, which would usher in the "hydrogen economy." A parallel situation would use a simple battery to store electricity…

An existing industrial hydrogen generation and distribution infrastructure is described, and a number of large-scale investment projects are outlined. All of these projects have the potential to generate significant volumes of low-cost, low-carbon hydrogen. The technologies concerned range from gasification of coal with carbon capture and storage…
