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…

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…

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 instructional resource utilizes consumer product information by which students compare theoretical stoichiometric calculations to CO[subscript 2] car emissions and fuel consumption data. Representing graphically the emission of CO[subscript 2] versus consumption of fuel provides a tangible way of connecting concepts studied in chemistry…

Concludes that coal will be the major U.S. energy source in the near future despite the significant problems associated with an increase in coal consumption. Provides advantages and disadvantages for the four major long-term energy sources: nuclear fission, nuclear fusion, geothermal sources, and solar energy. (MLH)

Discusses the possible advantages of decomposing water by means of thermochemical cycles. Explains that, if energy consumption can be minimized, this method is capable of producing hydrogen more efficiently than electrolysis. (GA)

Presents an activity that allows students to apply problem-solving skills and chemical principles to calculate the cost for converting a gasoline-powered vehicle to propane. (Author/ASK)

Discusses the world's energy requirements in contrast with the world's known and unknown energy reserves to illustrate the need for a stable and more equitable world-wide energy distribution system, especially for oil-importing countries. (CC)
