E85 critics contend that ethanol producers may not reduce carbon emissions due to the petroleum and natural gas used in raising corn and refining it. E85 advocates reply by pointing to ethanol producers who do not do so, but instead use E85 or biodiesel fuel to transport E85, and use biomass as a heat source for the distillation of ethanol ...
Concerns about rising gasoline prices and outside energy dependence led to a resurgence of interest in E85 fuel at the turn of the 21st century; for example, Nebraska mandated the use of E85 in state vehicles whenever possible in May 2005. Similarly, whereas selling any fuel containing more than 10% ethanol is currently illegal in some states ...
Grid energy storage, also known as large-scale energy storage, are technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power , releasing it when needed.
The total amount of energy input into the process compared to the energy released by burning the resulting ethanol fuel is known as the energy balance (or "energy returned on energy invested"). Figures compiled in a 2007 report by National Geographic [ 68 ] point to modest results for corn ethanol produced in the US: one unit of fossil-fuel ...

Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with ...
For energy storage, the energy density relates the stored energy to the volume of the storage equipment, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy.
Flexible-fuel cars, trucks, and minivans use gasoline/ethanol blends ranging from pure gasoline up to 85% ethanol . By early 2013 there were around 11 million E85-capable vehicles on U.S. roads. [10] [11] Regular use of E85 is low due to lack of fueling infrastructure, but is common in the Midwest.
