The two most common types of biofuel are bioethanol and biodiesel. Brazil is the largest producer of bioethanol, while the EU is the largest producer of biodiesel. The energy content in the global production of bioethanol and biodiesel is 2.2 and 1.8 EJ per year, respectively. [17]
Ethanol is not suitable for most aircraft, according to the RACQ, as well as some motorbikes and small engines, [40] though the Embraer EMB 202 Ipanema is an example of an aircraft that has been specifically designed for use with ethanol fuel in some variants.
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]
However, consistently drinking more than four units a day (for men) and three units (women) is not advisable. [88] Previously (from 1992 until 1995), the advice was that men should drink no more than 21 units per week, and women no more than 14. [89] (The difference between the sexes was due to the typically lower weight and water-to-body-mass ...
Our well-being is our treasure, and we need to protect it. The nice thing is that people generally understand this. For example, 17% of Americans describe their overall health as excellent, and 58 ...
That being said, many believe that the potential pros far out-weigh the short-term cons. [1] [2] The process of growing the tree biomass is energy efficient compared with growing corn or sugar cane for ethanol. However, it also takes longer to grow trees than to grow corn, and so any accurate research on sustainability and crop rotation (even ...
Except—groan—please don’t say that. This, and six other phrases that people really, truly need to stop saying to women over 40. 1. “Forty is.
On top of its beefy initial price, you have to pay another $500 for accessories and sign up for a 12-month membership to the Tonal service (another $60 a month).
