Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
With the use of non-edible vegetable oils produced by trees such as Millettia Pinnata (formerly Pongamia Pinnata) or the Moringa oleifera tree, both which grow on borderline or non-arable land, the food versus fuel debate becomes less of an either/or question. Apart from their facility of growing in non-arable and/or marginal land, these trees ...
Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane, natural gas, methane, and ammonia; biofuels like biodiesel, bioalcohol, and refuse-derived fuel; and other renewable fuels like hydrogen and electricity. [3]
Second-generation biofuels are made from different feedstocks and therefore may require different technology to extract useful energy from them. Second generation feedstocks include lignocellulosic biomass or woody crops, agricultural residues or waste, as well as dedicated non-food energy crops grown on marginal land unsuitable for food ...
The Maximus/Minimus food truck, at the corner of Pike Street and 2nd Avenue in downtown Seattle, Washington. A food truck is a mobile venue that transports and sells food. Some, including ice cream trucks, sell frozen or prepackaged food; others resemble restaurants on wheels. Some may cater to specific meals, such as the breakfast truck, lunch ...
The 2009 EU Renewable Energy Directive, which requires 10 percent of transportation energy from renewable energy by 2020, is the most comprehensive mandatory sustainability standard in place as of 2010.
The fuel, often referred to as electrofuel, stores the energy that was used in the production of the hydrogen. [11] Hydrogen fuel is typically prepared by the electrolysis of water in a power to gas process. To minimize emissions, the electricity is produced using a low-emission energy source such as wind, solar, or nuclear power. [12]
A United States Geological Survey (USGS) study found a significant long-term trend over the 20th century for non-renewable resources such as minerals to supply a greater proportion of the raw material inputs to the non-fuel, non-food sector of the economy; an example is the greater consumption of crushed stone, sand, and gravel used in ...
