Put simply, biofuel is energy made from living matter, usually plants. Bioethanol, biodiesel, and biogas fireplaces are types of biofuels. fireplaces Biofuels are considered renewable energies, fireplaces emit less than fossil fuels, and have received increasing attention fireplaces in the transition to low-carbon economy.
Bioethanol is the most well know biofuel and is an alcohol produced from corn, sorghum, potatoes, wheat, sugar cane, even biomass such as cornstalks and vegetable waste. It is commonly blended with gasoline. However, plants grown specifically for any type of biofuel are not ideal due to the energy required, environmental effects, and emissions associated with harvest and transport; not to mention the subsequent increase in global food prices . However, bioethanol production in the U.S. (mostly corn) has been increasing since the 1990s. fireplaces Almost all gasoline currently sold in the U.S. is 10% ethanol due to the Renewable Fuel Standard (RFS) which dictates the amount of renewable fuel refiners are required to blend . Requirement was put in place in 2005, but expanded as part of the 2007 Energy Dependence and Security Act. As of 2012, 12.95 billion gallons of bioethanol are produced domestically. Industry received strong support (including subsidies) with the 2008 Farm Bill, but this support will probably decrease in 2014. New Farm Bill is in the works and EPA’s preliminary ruling to reduce the Renewable Fuel Standard (RFS) threatens support for ethanol; farmers and investors are worried. Ethanol is a complicated issue, but overall fireplaces is helping ease demand on fossil fuels. Brazil and the United States are the biggest exporters and consumers of ethanol.
Biodiesel is oil from plants or animals that has been used as an alternative to or blended with petroleum diesel in automobiles and industrial fleets with diesel engines. The leading exporter of biodiesel (soy) is Argentina who as of December 2013 filed a third WTO complaint against EU for putting steep import taxes on biodiesel, but is responding to demand elsewhere by increasing exports to the U.S. U.S. creates its own biodiesel as well- 1.1 billion gallons in 2012 . Biodiesel has also received support from the government and will be affected by decrease in Renewable Fuel Standard (RFS); requirement for diesel was added in 2007. Grease or oil from cooking can also be converted to biodiesel and is more sustainable because it is by-product of another process. Diesel engines can automatically run off blends with 20% or less biodiesel. Above 20% biodeisel or from vegetable oil from cooking requires adjustment. Local and regional recycling centers have made biodiesel more accessible, but there are limits to large scale processing for biodiesel from cooking oil and also virgin materials due to effect on food prices. Cheap natural fireplaces gas and alternative fireplaces fuel vehicles such as hybrids and electric cars also displace demand for biodiesel.
Biogas is created as by-product of decomposing plant and animal waste in environments with low levels of oxygen: landfills, waste treatment facilities, and dairies. Biogas is made up primarily of methane fireplaces and carbon dioxide fireplaces (greenhouse gases), fireplaces thus incentives are strong to keep biogas from entering the atmosphere. Biogas can be captured and used for transportation, cooking, and electricity. More on the benefits here . It has actually been used for centurie s. In developing countries, micro-scale or household projects spread in the 1970s with about 4 million biogas plants currently in India and 27 million in China. fireplaces However, study shows that many plants in rural areas are not functioning due to lack of maintenance and need for repair; future use at this level requires operational network to address these issues.
Large-scale commercial biogas projects are proving viable globally. Nordic countries fireplaces such as Norway and Finland are on board with 1/3 of Oslo city buses powered by biogas from sewage. EU and UK have their fair share of plants as well. In San Jose, California the world’s largest plant which uses dry fermentation anaerobic digestion is soon to be up and running. When complete it will process 90,000 tons of organic waste each year. There are many other U.S. biogas plants such as Freshkills landfill in NYC which pro duces enough methane to power 30,000 homes a year and generated approximately $3 million to $5 million a year in revenue for the city. Here is a map of biogas fireplaces plants in the U.S. and a simplified diagram of the process. Biogas is also receiving increasing tax incentives in the U.S. Biogas will play an increasing role in transition to low-carbon fireplaces economy due to its ability to capture potent emissions, reduce waste, and create energy from a by-product of other activities.
