  2. Water-energy nexus - Wikipedia

    en.wikipedia.org/wiki/Water-energy_nexus

    Hybrid Sankey diagram of 2011 U.S. interconnected water and energy flows. The water-energy nexus is the relationship between the water used for energy production, [1] including both electricity and sources of fuel such as oil and natural gas, and the energy consumed to extract, purify, deliver, heat/cool, treat and dispose of water (and wastewater) sometimes referred to as the energy intensity ...

  3. Boron - Wikipedia

    en.wikipedia.org/wiki/Boron

    This use is a very small fraction of total boron use. Boron is introduced into semiconductors as boron compounds, by ion implantation. [citation needed] Estimated global consumption of boron (almost entirely as boron compounds) was about 4 million tonnes of B 2 O 3 in 2012. As compounds such as borax and kernite its cost was US$377/tonne in 2019.

    en.wikipedia.org/wiki/Energy_efficiency_in_transport

    Natural Resources Canada's Office of Energy Efficiency publishes annual statistics regarding the efficiency of the entire Canadian fleet. For researchers, these fuel consumption estimates are more realistic than the fuel consumption ratings of new vehicles, as they represent the real world driving conditions, including extreme weather and traffic.

  7. Gasoline gallon equivalent - Wikipedia

    en.wikipedia.org/wiki/Gasoline_gallon_equivalent

    The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline. Simple calculations of the BTU values of the ...

  8. Energy content of biofuel - Wikipedia

    en.wikipedia.org/wiki/Energy_content_of_biofuel

    Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass , which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [ 1 ]

  9. Boron cycle - Wikipedia

    en.wikipedia.org/wiki/Boron_cycle

    Boron in the atmosphere is derived from soil dusts, volcanic emissions, forest fires, evaporation of boric acid from seawater, biomass emissions, and sea spray. [1] Sea salt aerosols are the largest flux to the atmosphere. On land, boron cycles through the biosphere by rock weathering, and wet and dry deposition from the atmosphere. [1] [2]
