Biofuels | Watts Up With That?

By way of Andy Would possibly

In keeping with Exxon-Mobil, nine% of the arena’s calories got here from biofuels in 2017. They don’t be expecting this proportion to extend via 2040, and it should pass down. For essentially the most section this is a creating international gas. Number one biofuels come with dung, wooden, wooden chips and pellets. Secondary, or manufactured biofuels come with ethanol and biodiesel, which derive from a number of agricultural merchandise, basically corn, sugar cane, palm oil, soybeans and canola. The primary good thing about the usage of in the community sourced wooden and dung are their low price and extensive availability. The use of imported wooden or wooden chips for producing electrical energy, as is completed in Europe, is extra problematic. Because of the commercial and environmental prices of farming the timber, making the wooden pellets or chips and transport them to the powerplants; wooden isn’t a aggressive gas for many powerplants. The calories density is simply too low. Alternatively, if the supply of the wooden is inside fifty miles of the plant, it will also be aggressive with coal and it should produce fewer greenhouse gases than coal, estimates range. Ethanol and biodiesel also are costlier than fossil fuels and will have to be backed to be aggressive.

International, biofuels (that means biomass + transportation biofuels + waste) are the most important renewable calories supply. In 2017, bioenergy accounted for 60 to 70% of renewable calories intake. In the similar yr, biofuels equipped about 3 % of the calories utilized in transportation, this used to be basically biodiesel and ethanol. International, about 95% of the renewable calories used for heating and cooking in the house, on farms, in eating places and via boulevard distributors, used to be from burning dung or wooden. This reasons really extensive indoor air air pollution and the Global Well being Group (WHO) estimates some 4 million other folks die once a year consequently. In 2017, 86% of the biomass, burned for calories, used to be used for cooking or heating houses, many of the the rest used to be ethanol or biodiesel.

Ethanol, biodiesel and wooden as gas: The economics

Biofuels have a low to very low calories density, relative to fossil fuels or nuclear gas, and you wish to have lot of biomass to supply a lot calories. Biofuels, except for some biodiesel merchandise, additionally motive a large number of air pollution, this comprises the air pollution created when rising the product, similar to wooden, palm timber, soybeans, canola or corn; the air pollution created when ethanol or biodiesel are manufactured; and when the product is burned. An exterior price of biofuels is that the usage of them can carry the price of meals, that is in particular true of corn ethanol. Every other exterior price is that generating, and production biofuels makes use of a large number of water and water availability is an issue in lots of portions of the arena.

Ethanol is corrosive, it incorporates oxygen, it draws water, and will motive metal to crack. Which means that it can’t be installed commonplace pipelines and ceaselessly will have to be trucked. This will increase prices and lowers the biofuel’s EROI (calories returned on funding).

EROI is a ratio, the numerator is the calories produced via the general product and the denominator is the full calories used to supply it. The denominator is in most cases computed the usage of price information as a proxy for the calories enter. As a result of prices are used, computed EROI’s for any gas can range so much between international locations. That is due, basically, to variations in hard work and land prices. Thus, for a given gas product, a advanced nation may have a decrease computed EROI, because of a bigger denominator, than an undeveloped nation, the place residing requirements, wages, and land have decrease prices. As we can see, this impacts the commercial breakeven EROI. In international locations with a top lifestyle, the next EROI is needed to take care of their top lifestyle. In an effort to take care of a top lifestyle, each and every individual will have to use extra calories.

In concentrations above 20% via quantity, ethanol, in both fuel or diesel, can smash engines that don’t seem to be specifically changed for the gas. This may be true of a few sorts of biodiesel. That is this sort of danger that automobile and truck producers will now not honor warranties for many automobiles if the landlord purchases fuel or diesel with greater than 10% ethanol.

Some declare that burning wooden to supply electrical energy produces “just right” CO₂ since the timber minimize down for gas shall be changed via timber that can take in the CO₂. This will or is probably not true, however both means the price of chopping down timber, planting new ones, making ready and transporting the wooden to an influence plant will also be so top, as to restrict its use within the absence of subsidies and mandates. The EU is the arena’s greatest wooden pellet marketplace, in large part because of mandates. Within the EU, Italy and Germany are the most important shoppers.

The EROI of a gas, particularly a transportation gas, will have to exceed 3 for it to be helpful and a few researchers set the commercial prohibit even greater. The EROI of burning wooden for electrical energy may be very low, round 10 (Nationale Akademie der Wissenschaften – Leopoldina 2012, p. 10). It’s a lot not up to the EROI of burning coal (45 to 80), even with a complete set of air pollution scrubbers at the coal-burning energy plant. For decrease high quality coal or lignite, similar to that utilized in Germany, the EROI will also be as little as 30. The EROI of corn-based ethanol, for comparability functions, is between 1.25 and three.five.

Some argue that the calories put into corn farming and ethanol manufacturing exceeds the calories yield from the gas (Patzek 2014). Or, put otherwise, “The fossil calories inputs required for farming and processing ceaselessly cancel out many of the calories delivered” (Nationale Akademie der Wissenschaften – Leopoldina 2012, p. nine). The U.S. taxpayer subsidies to the economic corn-ethanol business have been $three.three billion in 2004. The rise in biofuel manufacturing truly took off in 2005 and this used to be one of the crucial reasons of an build up in meals costs that started that yr, see (Tyner 2008). When ethanol manufacturing flattened out in 2012 because of the ethanol 10% “mix wall” (see under for main points) then meals costs stopped emerging.

The rationale many wish to use biofuels is they hope the usage of them will cut back greenhouse emissions. Alternatively, a lot of research have proven that isn’t the case. In August 2012 the German Nationwide Academy of Sciences discovered that taking away biomass from the world the place it used to be grown and the usage of it for gas is:

“… neither renewable nor carbon impartial, as an alternative it’s energy- and CO₂ unfavourable.” (Nationale Akademie der Wissenschaften – Leopoldina 2012, p. 6)

That is obvious as a result of taking away the biomass additionally eliminates vitamins had to develop the crops, they will have to get replaced the usage of manufactured fertilizer. The carbon cycle can’t be separated from the nutrient cycle totally free (Nationale Akademie der Wissenschaften – Leopoldina 2012, p. 6). Insecticides also are had to build up yield, farming calls for a large number of apparatus and gas, and the land used for the biomass farm is land which may be wooded area or grassland that might sequester carbon or a farm generating meals, lowering meals prices. The lack of arable land has a value, it will increase the price of meals or it emits greenhouse gases.

Algae biodiesel

ExxonMobil and Artificial Genomics, Inc. have advanced a pressure of algae that is in a position to convert carbon into an energy-rich fats that may be processed into biodiesel (Ajjawi, et al. 2017). Making biofuels from algae isn’t new, however this actual genetically-modified species of algae is greater than two times as calories wealthy (two times the fats content material) as different sorts of algae. An important good thing about this algae is that rising it does now not require farmland and it has little to no impact on our meals provide. It is a promising era, however nonetheless within the analysis degree and the commercial viability of this renewable possibility isn’t identified.

The U.S. Division of Power (DOE) spent thousands and thousands of greenbacks making biofuels from algae between 1978 and 1996 prior to shutting the venture down with none certain effects (Kiefer 2013, p. three). The issues recognized via the DOE have been basically financial. The primary distinction with the Exxon-Mobil venture is within the algae used.

Ethanol from corn and cellulose and the ethanol mandate

The U.S. govt Renewable Gas Same old (RFS) mandates that the crude oil refining business purchase a certain amount of ethanol each and every yr and pay heavy fines in the event that they don’t. They’re ordered to shop for a product they don’t want and punished in the event that they don’t purchase it, but some information assets declare it is a subsidy to the fossil gas business. The EPA administers this system and has the authority to waive the statutory ethanol goals. This has had the impact of constructing the rule of thumb unpredictable and arbitrary. Additional, the mandate to make use of extra cellulosic ethanol, ethanol from grass and different non-standard vegetation, hasn’t ever labored. The producing procedure has technical and financial hurdles which are overwhelming. So, the mandate to make use of cellulosic ethanol, a supposedly “complex” biofuel has been waived once a year since 2013. Exxon-Mobil and a few different firms are nonetheless searching for an financial option to convert cellulose to biodiesel, however no viable answers had been discovered. It’s value taking into consideration that the primary cellulosic ethanol plant opened in the US in 1910 and it failed. So, in spite of 110 years of making an attempt, cellulosic ethanol and biodiesel are nonetheless now not economically viable (Kiefer 2013, p. three). Mandating the usage of a era that has now not been invented but is silly, however we’re speaking concerning the govt, they know little or no about financial viability.

Each and every yr the EPA dictates the specified general volumes of quite a lot of transportation biofuels for the next yr. Then it initiatives the volume of gas intake anticipated for the length and dictates the volume of ethanol that the refining business will have to acquire, without reference to how a lot they are able to use. Each and every gallon of ethanol produced or imported is assigned a singular renewable identity quantity, a “RIN.” Those RIN’s are tradable and will also be purchased via refineries to offset ethanol they’re ordered to buy however can’t use. A refinery that makes use of greater than they’re ordered to make use of can promote RINs. In a different way to procure RINs is to buy dear “complex” biofuels or biodiesel from out of the country in order that they over-comply with the “complex biofuel” a part of the RFS to realize RINs. See a up to date put up via Paul Driessen right here.

An issue is created since the ethanol manufacturers need the federal government to power the refiners to take extra ethanol, however the refiners face a “mix wall.” With lately’s engines, the utmost ethanol content material in fuel is 10%, greater than that and engine harm may result. To make issues worse, gross sales of closely backed electrical automobiles and hybrids and automobiles with higher fuel mileage are lowering the full call for for fuel. The mandate is for volumes of ethanol, regardless of the amount of fuel bought. Many refiners put as a lot ethanol as they are able to into their fuel, however will nonetheless fall in need of the federal government mandates, so they’re compelled to shop for RINs from others, particularly biodiesel producers, ceaselessly those producers are out of the country firms. This drives up the cost of RINs, that means that biodiesel and the strong point 85% ethanol gas are closely backed just because they generate treasured RINs.

The compliance burden falls maximum closely on massive refiners, as a result of small refineries are mechanically granted exemptions from the RFS necessities. In August of 2019, 31 small refiners have been granted exemptions from the RFS. The indignant corn-ethanol manufacturers then furiously bitch and insist that the EPA permit the sale of higher-percentage ethanol blends, carry the RFS and forestall granting exemptions. This reasons the auto producers to refuse to honor their automobile warranties to somebody that places greater than 10% ethanol fuel of their automobiles. If refiners are compelled to pay any longer for his or her RINs, they declare they’ll pass bankrupt. This can be a best whirlwind of lobbyists, legal professionals and govt bureaucrats, who’re the one ones who make any cash out of this mess. It is a best candidate for deregulation, however as an alternative President Trump ordered the EPA to transport in opposition to E15 (fuel with 15% ethanol) and has prompt fixes for the RIN marketplace, he necessarily caved to the ethanol and farm lobbies.

Lately, Reuters reported that the Trump management has determined to vastly cut back the EPA’s program to exempt small oil refineries from the rustic’s biofuel laws. The Trump management has greater than quadrupled the choice of exemptions since 2015, protective numerous small refineries. Alternatively, the 10th Circuit Courtroom of Appeals has dominated that the EPA exceeded its authority since lots of the new exemptions are for refineries that had now not gained the exemption prior to, it dominated that the refineries getting the exemption will have to have up to now gained one. As of March four, 2020, the EPA has now not mentioned what it is going to do, however said that they had to “quell” the marketplace for RINs. The marketplace for fuel and diesel has contracted, however the ethanol mandates have now not.

Prices and advantages of biofuels, EROI

The Nationwide Academies of Sciences says that biofuels can simplest be aggressive, with out subsidies and mandates, if fuel prices over 5 bucks a gallon or when crude oil reaches $191 in step with barrel. Those are costs we’re impossible to succeed in within the foreseeable long run.

As defined above, calories used to make a gas, like a biofuel, will have to be a lot not up to the calories output for the gas to be helpful. An EROI of 1 method simply as a lot calories used to be used to make the gas as we will be able to get out of it, however this isn’t just right sufficient. We’re inefficient in the way in which we use gas, as an example automobiles with typical fuel engines are simplest about 30% environment friendly and herbal fuel combined-cycle electrical energy crops are simplest 50% environment friendly, so an EROI of 1 isn’t just right sufficient. The most efficient sun panels convert 15% to 22% of the solar’s calories into electrical energy and will have to cope with cloudy days and middle of the night. Windmills are simplest 38% environment friendly on reasonable and simplest extract 50% of the calories that flows during the rotor space. Sun and windmill general potency varies with location, however in Germany, on reasonable, sun potency is Eight% of rated capability and wind is 17% of rated capability.

Estimates range, however, maximum calculations display that corn-based ethanol has an EROI of only one.25 (Kiefer, 2013). Different estimates are as top as three.five (Weissbach, et al. 2018). Once we imagine the lack of calories when the usage of ethanol in a automobile, it is a unfavourable go back. Automobiles and vehicles don’t seem to be completely environment friendly, so breakeven has been estimated to be round 3 via Corridor, et al. (2009). In keeping with Kiefer, even historic Rome did higher with grain for slaves, oxen and horses, their most EROI used to be about four.2. In construction the colosseum the EROI used to be 1.Eight. Weissbach, et al. (Weissbach, et al. 2018, p. 7-Eight) position the EROI financial threshold a lot greater, at about 10:1 to take care of our fashionable lifestyle, that could be extra reasonable. Weissbach additionally explains the variation between fossil fuels and wind and sun, which require “buffering” (Weissbach, et al. 2018, p. Eight) to easy out their fluctuations in output.

Weissbach explains that the strategies used to compute EROI and the rustic used to do the computation have an effect on the calculation, as we discussed above. For instance, a herbal fuel turbine in a much less advanced nation may have the next EROI than one in an industrialized nation, that is because of the cheaper price of work within the much less advanced nation. Cash is a superb proxy for the enter calories in an influence plant however the usage of prices as enter adjustments the computed EROI for any given energy supply in keeping with the positioning.

Coal-fired steam engines got here alongside within the 1800s with an EROI of 10:1 or extra. Within the early coal mining days extracting coal used to be really easy because it used to be out there on the floor or very close to the outside. This used to be a just right factor as a result of early steam engines have been very inefficient. Alternatively, as coal-fired steam engines proliferated they changed slave hard work, so the social and financial advantages have been massive.

Our civilization is dependent very a lot on EROI as the excess calories (calories now not utilized in acquiring and the usage of fuels) is helping outline our affluence. As a result of we lately revel in a big calories surplus, we will be able to spend our time doing different issues than just rising meals and amassing wooden for safe haven or to cook dinner the meals.

It’s smartly documented that wealth and lifestyle are intently associated with calories intake (see Determine 1). Clearly, calories intake is expounded to worth, the inexpensive the calories the extra we devour and the at an advantage we’re. Timothy Garrett (2011) has proven that each and every further nine.7 milliwatts ate up will increase our world wealth via one 1990 U.S. greenback. Different documentation of the intimate dating between calories intake and wealth will also be observed right here and right here. The fastest solution to carry other folks out of poverty is to offer them with inexpensive calories and the fastest solution to throw extra into poverty is to boost the cost of calories.

The U.S. devotes 38 million acres of land to corn raised to make ethanol, that is about part of the land used within the U.S. to develop grains and greens. The cost of corn went from $87 in step with metric ton in 2006 to $217 in step with metric ton in 2008, an build up of 150%. This fast bounce in worth used to be an unintentional outcome of the ethanol subsidies and better oil and fuel costs (Tyner 2008).

The diversion of arable land for ethanol manufacturing raises the cost of all meals and as the U.S. is a significant exporter of meals, it raises costs in all places the arena. It’s estimated that the price of rice and flour larger 50% after the RFS used to be created. The RFS is a hidden meals tax this is extremely regressive and impacts deficient other folks a lot more than the center elegance or wealthier other folks.

The good judgment in the back of the RFS is that corn ethanol is meant to cut back carbon dioxide emissions via 20% over the fuel changed. Alternatively, this depends on the way in which the corn used to be grown and transformed into ethanol. Some research recommend that the 20% aid is greater than offset via emissions at the farm and within the distillery. Additional, the farm and distillery emit ozone, particulate subject and sulfur dioxide. The farms additionally use a large number of nitrogen-based fertilizers, which produce nitrogen oxides that pollute the air or will also be washed into rivers inflicting water air pollution.

The nitrogen-based fertilizers used lately come from the Haber-Bosch procedure that makes use of herbal fuel (methane), water and nitrogen from the ambience to supply ammonia, which is then used to make fertilizer, see Determine 2. More or less 3 to 5 % of the herbal fuel used on the earth on a daily basis is used to make fertilizer. Herbal fuel isn’t required to make the fertilizer, however all different assets of hydrogen are too dear to be sensible. Each Fritz Haber and Carl Bosch gained Nobel Prizes for his or her paintings creating the producing procedure. These days’s corn crops are bred and genetically engineered to optimize their use of this ammonia-based fertilizer. This has allowed farmers to boost the pre-Haber-Bosch corn yield from about 32 bushels in step with acre in 1906 to 170 bushels of corn in step with acre lately (Kiefer 2013, p. Eight). The intensive manufacturing of corn-ethanol would now not be imaginable apart from for the huge quantity of herbal fuel used to make fertilizer. If we have been to select to not produce herbal fuel by the use of a ban on hydraulic fracturing, corn yields would plummet to pre-Global Struggle II ranges and corn-ethanol manufacturing would grind to a halt.

Different processes for making ammonia from air are being investigated and a few display promise, similar to the brand new SWAP procedure. However none are running at a industrial scale but. Some of the issues of SWAP is that it calls for a large number of samarium, which may be very dear, about $360 in step with 100 grams.

The irony of pushing to exchange fossil fuels with corn-ethanol, is plain. Fossil fuels are required to fertilize, develop and shipping the corn used to make ethanol. Production ethanol calls for herbal fuel, then particular plumbing and pipelines are required to move it. If greater than 10% ethanol is mixed into fuel or diesel, particular engines are required to burn it. Excluding to lobbyists and legal professionals, it is senseless.

Soybean, palm, canola oils and biodiesel

Corn-based ethanol has its issues, however the soybean oil, canola oil and palm oil used as biofuels (biodiesel) in Europe and the usA. are most certainly worse. The Eu Union and the U.S.A. closely subsidize those biofuels, and this has raised the cost of palm and soybean oil. Whilst subsidizing biodiesel thru renewable calories insurance policies, the EU additionally criticizes and punishes different international locations, together with the U.S. for subsidizing the similar items. The top call for for palm-oil biodiesel has brought about Indonesia, Malaysia and different generating international locations to chop down their forests and develop massive vegetation to promote to Eu refineries. The schizophrenic aggregate of each subsidies and price lists on biodiesel expose how nonsensical the entire idea is. When U.S. biodiesel subsidies have been withdrawn in 2016, ten producers close down. The entire business would most certainly disappear with out subsidies. Western economies require a top EROI and each Weissbach and Kiefer imagine that biodiesel and different biofuels are subeconomic there. The U.S. biodiesel subsidies have been reinstated and made retroactive in 2019.

Canola (rapeseed) is grown in Europe, Canada and different international locations and used to make biodiesel in lots of places. Within the U.S. soybean oil is most well-liked as a feedstock for biodiesel, however canola oil and recycled cooking oils also are recurrently used. Within the U.S. biodiesel is recurrently mixed with petroleum diesel in percentages starting from five% to 20% biodiesel.

Palm-oil biodiesel (mixed 20% to 50% with petroleum diesel) ends up in decrease emissions of carbon monoxide, particulates (smoke) and hydrocarbons than common diesel, but when that palm-oil got here from a cleared tropical rainforest, in keeping with the EU, then palm-oil biodiesel isn’t sustainable and must now not qualify underneath the EU RFS. Of the entire feedstock vegetation for biodiesel, palm oil has the absolute best traits as a gas, 2nd simplest to petroleum diesel. It is usually much less more likely to harm engines. All vegetable oil-based biodiesel merchandise go to pot with time (biodegrade) however palm-oil appears to be essentially the most strong.

Even supposing Sir Rudolf Diesel ran his typical diesel engines the usage of vegetable oil with none amendment, lately this isn’t sensible. Vegetable oils, together with palm-oil, have a big molecular mass, low volatility and top viscosity, this reduces the efficiency of the engine and, in low temperatures, reasons the gas to develop into an unpumpable gel. As well as, they have got a brief shelf existence. To resolve those issues, the vegetable biodiesel is in most cases mixed with petroleum diesel or alcohol and a surfactant at increased temperatures. Different processes to organize biodiesel for contemporary diesel engines are complicated chemical processes, together with pyrolysis and transesterification. Those processes create a product that may harm engines (Nationale Akademie der Wissenschaften – Leopoldina 2012, p. 47) and the processes create a large number of wastewater that calls for dear processing prior to it may be discharged (Zahan and Kano 2018, p. 2).

Within the manufacturing of biodiesel, simplest the lipid fraction is used, and that is simplest 20-50% of the plant dry mass, thus the calories yield in step with sq. meter of farmland is not up to for ethanol and far not up to for biogas. Simply as critical is the possible harm to very dear diesel engines, the dangers are top sufficient that the producers of more moderen, extremely environment friendly engines have refused to sanction the usage of biodiesel of their automobiles. The hazards to engines come with dilution of motor oil, coking of piston rings, corrosion of hydraulic parts (together with hydraulic traces, a security factor) and fouled injectors. Those issues get up from deficient manufacturing practices and gas growing older, because the gas deteriorates with age (Nationale Akademie der Wissenschaften – Leopoldina 2012, p. 47).

Whilst biodiesel can decrease the emissions of CO₂ and particulate subject, it will increase gas intake in step with mile, reduces engine energy, and will increase NOx (nitrogen oxides, a circle of relatives of pollution) emissions. The primary price of constructing biodiesel is the price of the feedstock, as a result of vegetable oil is costly. Within the U.S., biodiesel used to be 15-30% costlier than petroleum diesel in 2017, even with subsidies (Zahan and Kano 2018).

Dialogue and Conclusions

Biofuels don’t seem to be economically viable at lately’s oil and herbal fuel costs. Their EROI won’t maintain the quality-of-life a advanced country is used to lately. In different phrases, to undertake biofuels, the western international will have to both closely subsidize them, enforcing a hidden tax on their electorate with the intention to improve farmers and biofuels producers, or they will have to settle for a far decrease quality-of-life, aka “Human Building Index,” as proven in Determine 1.

Despite the fact that petroleum oil and fuel costs have been to upward thrust to a degree the place biofuels may just compete on a degree enjoying box, with lately’s era, the biofuel EROI presentations us that our lifestyle must pass down considerably. There’s no reason why to prop up biofuels for some unsure long run, their EROI on my own presentations us shall we now not use them underneath any cases. If pressed via top fossil gas costs, we might select a gas with the next EROI, like nuclear fission or fusion, with the intention to take care of our quality-of-life and standard-of-living. Other folks hate to move backwards, which is what biofuels would call for.

How did we get right here? The unique ethanol subsidy used to be a part of the 1978 Power Coverage Act (Tyner 2008). It used to be at first 40 cents in step with gallon, it has various from 40 to 60 cents in step with gallon ever since and is lately 45 cents. That is on most sensible of state and native subsidies that may carry the full to $1.38 in step with gallon. The subsidy program used to be revised underneath President George W. Bush in 2004. Each, the unique subsidy and Bush’s Volumetric Ethanol Excise Tax have been intended to lend a hand The usa succeed in calories independence. Alternatively, the U.S. is already calories impartial because of shale fuel and oil, invalidating the unique reason why for the subsidies.

After the U.S. used to be smartly on its solution to calories independence, U.S. Senator Tom Coburn led an effort to repeal the ethanol subsidy in 2011, however the repeal used to be fought vigorously via Iowa Senators Chuck Grassley and Joni Ernst, it didn’t go via 59 to 40. The corn and ethanol lobbies are very robust.

The Power Coverage Act of 2005 mandated a one greenback a gallon subsidy for brand spanking new agricultural biodiesel and 50 cents to used feedstocks like fryer grease. This tax credit score expired in 2016 and ten biodiesel producers close down, then it used to be retroactively prolonged past due in 2019. Some articles declare this subsidy and the ethanol subsidy get advantages the oil and fuel business, which is nonsense, it hurts each them and the shopper. That is why small petroleum refineries are granted RFS waivers, so they don’t close down. The small refineries are even granted waivers if they’re owned via Exxon-Mobil, and for just right reason why, we wish them to stick open. The subsidies get advantages farmers and ethanol and biodiesel refineries, which don’t seem to be a part of the oil and fuel business. Simply extra pretend information about oil and fuel subsidies, very similar to the false declare that the Low Source of revenue Power Help (LIHEAP) welfare program is an oil and fuel subsidy.

So, we see how a central authority program, created right through an oil and fuel disaster in 1978, turns into an enduring company welfare program for farmers and biofuel refiners. It has created a constituency this is utterly dependent upon govt handouts. Like any such methods, the taxpayers and shoppers are the sufferers.
