Brazilian cerrado Amazon rainforest. The indirect land use change impacts of biofuels, also known as ILUC or iLUC (pronounced as i-luck), relates to the unintended consequence of releasing more carbon emissions due to land-use changes around the world induced by the expansion of croplands for ethanol or biodiesel production in response to the increased global demand for biofuels.
Recent developments with cellulosic ethanol production may improve yields even further. [12] In 2006 a study from the University of Minnesota found that corn-grain ethanol produced 1.25 units of energy per unit put in. [13] A 2008 study by the University of Nebraska found a 5.4 energy balance for ethanol derived specifically from switchgrass.
The production of fuel ethanol from corn in the United States is controversial for a few reasons. Production of ethanol from corn is 5 to 6 times less efficient than producing it from sugarcane. The reason that corn has been notoriously used for ethanol production is because farmers are either paid to destroy crops or to not grow corn crops.
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 ...
Fossil fuels produced just 33% of the European Union's power in th. Europe is making itself stronger against Russian attempts to weaponize energy by switching to clean sources faster, U.S. Special ...
The main source of renewable energy in 2019 was biomass (57.4% of gross energy consumption). [2] In particular, wood is the leading source of renewable energy in Europe, far ahead of solar and wind. [3] In 2020, renewables provided 23.1% of gross energy consumption in heating and cooling.
Shifting to renewable energy "can help us to meet the dual goals of reducing greenhouse gas emissions, thereby limiting future extreme weather and climate impacts, and ensuring reliable, timely, and cost-efficient delivery of energy". Investing in renewable energy can have significant dividends for our energy security. [25]
