  • Plug-In Hybrid Campaign

    Posted: 2006-09-03 00:58


    I encourage everyone to sign this online plug in hybrid campaign urging automakers to produce plug-in hybrid electric vehicles (PHEVs). The petition basically says, 'If you build it, we will buy it.' Plug-in hybrids and electric vehicles are key to energy independence and reducing pollution.

    Over 40 percent of the generating capacity in the U.S. sits idle or operates at a reduced load overnight, when most PHEVs would be charged. That means tens of millions of plug-ins could be charged every night without the need to build additional electric generation capacity.

    According to the California Electric Transportation Coalition that commissioned a study, if automakers begin producing Plug-Ins within the next few years, 2.5 million cars (eight percent of the cars on America's roads) could be Plug-Ins by the year 2020. That's the equivalent of taking as many as 5 million of today's vehicles off the road. Annually that's 11.5 million tons of CO2 which won't be emitted and 1.14 Billion gallons of gasoline would be saved each year. For those concerned about energy security it is definitely a step in the right direction. Less than 2% of U.S. electricity is generated from oil, so using electricity as a transportation fuel would greatly reduce dependence on imported petroleum.

  • Is Ethanol / E85 Fuel the Solution?

    Posted: 2006-07-26 11:12


    I've recently received a number of emails calling for me to Kick the Oil Habit by supporting E85 which is a liquid fuel made up of 85% ethanol and 15% regular gasoline. Having previously had my doubts about ethanol I emailed fellow blogger the Engineer Poet seeking his opinion. A large part of this resulting post is based directly on his reply and as such the credit belongs to him.

    So is E85 fuel the answer to America's (and the world's) addiction to oil?

    E85 fuel is not the solution. It is not even a part of the solution, it is a part of the problem. Here's why, in a nutshell:

    All US vehicles can burn 10% ethanol (E10), but the US does not even produce half as much ethanol as universal E10 would require. We make about 5 billion gallons of ethanol, but use 140 billion gallons of gas.

    E85 and "flex fuel" is a loophole for the automakers to sell guzzlers without having to pay CAFE penalties. It makes the problem worse. Ending the loophole probably means ending E85, because there is no other reason for it to exist.

    Since the best estimate is that every gallon-equivalent of ethanol takes about 4/5 of a gallon-equivalent of other fossil fuel to make it, each gallon of E85 really represents about 0.6 gallons-equivalent of various fossil fuels. Since most flex-fuel vehicles get roughly 2/3 the mileage on E85 as they do on gasoline, they burn about 90% as much fossil energy even at their best.

    Even if we can use "cellulosic ethanol" to reduce the inputs of fossil-derived fertilizer and whatnot, we can't make enough no matter what we do. The efficiency of the average gasoline-powered vehicle is about 15%, and we just can't grow enough inputs to make up for throwing 85% of our produced energy away. The most efficient use of biomass is in local combined heat and power plants, not as a feedstock for ethanol.

    Low corn prices and high oil prices, and a government subsidy of 51 cents per gallon have fuelled unprecedented growth of the ethanol industry. In the case of the U.S. ethanol industry, fossil fueled trucks ship the fuel halfway across the country from the population sparse corn belt to population and car dense states like California and Texas. Science magazine found only a 13% reduction in CO2 emissions for bioethanol over gasoline (and only 11% for E85 fuel). U.S. government federal records show a single ADM corn processing plant in Clinton, Iowa generated nearly 20,000 tons of pollutants including sulfur dioxide, nitrogen oxides, and volatile organic compounds in 2004. The EPA considers an ethanol plant as a "major source" of pollution if it produces more than 100 tons of any one pollutant per year. From an emissions standpoint it is far preferable to drive a fuel efficient gasoline car than a low efficiency flex fuel vehicle running on E85.

    E85 fuel is not a solution. It is a distraction, like hydrogen vehicles. Further, every E85 vehicle is also a gasoline-compatible vehicle. It will maintain demand for petroleum as long as it is on the road. If you want to end oil addiction you have to get rid of the things which use it.

    E85 ethanol fuel may make a small contribution now, but it is a dead end. If we want to really be free of fossil fuels (including imported oil), we have to re-think things as completely as changing from riding horses to driving motor cars.

    Ethanol has already created an addiction of its own. The farmers and agribusiness interests which got into it found it hugely profitable, and they have big investments in its continuation. Even if you developed a better way of using corn today, you'd still have a lot of money lobbying to use it for ethanol, and even force it to be used for ethanol.



    This is already a race between technologies which can make us independent of fossil fuel, and technologies which get subsidy money. In that race, the subsidy seems to win every time. At least 43 percent of Archer Daniels Midland's annual profits are from products heavily subsidized or protected by the American government. For every $1 of profit earned by ADM's ethanol operation (the largest in the U.S.), it costs taxpayers $30. If you subsidize a technology which can only replace half our gasoline (and none of our diesel, jet fuel, or anything else), you're probably going to be stuck with it.

    A hobbyist wrote an article about his home-built plug-in hybrid electric vehicle (PHEV). He published this article in Mother Earth News... in 1978.

    We don't need any new technology. We could be building these cars today. Heck, we could have been building them in 1995 (when the CARB ZEV mandate came in)... or maybe even 1985. They would have been crude, but they would have gotten the job done. We can do far better today, of course.

    People finally got fed up and started building their own PHEV's out of Toyota Priuses. It's time to quit the excuses, both making them and accepting them.

    CAFE regulations utterly failed to contain U.S. motor-fuel consumption. This is not opinion, this is historical fact. Now the E85 fuel campagin wants to do the same thing again, but "reduce" consumption with E85 instead of directly cutting gallons-per-mile. You'll get the same result as before - if driving doesn't cost more, people will continue to drive as much or more.

    There are roughly 200 million light-duty vehicles in the USA. One recent news item says that there will be all of 6 million flex-fuel vehicles by 2007. That's a whole 3%.

    The average flex-fuel vehicle is a guzzling truck (because they get the biggest CAFE preference from it). If those trucks get 13 MPG on E85, and they drive the national average of 13,000 miles/year, those 6 million vehicles would consume 5.1 billion gallons of ethanol. That's roughly the same as the total production capacity of the nation.

    The E85 fuel campaign is currently sponsoring a road trip to highlight the usage of E85, but also the difficulty of driving a car solely on E85 due to its lack of availability.

    However, had this trip been made in a Tesla Roadster or tZero from AC Propulsion, it could have instead highlighted how EASY it is to get electricity wherever you are... even if you never stop at a filling station! Using non-toxic lithium-ion batteries they have a 250 mile range, charging overnight from an electric outlet.

    E85 fuel is a distraction, a diversion, a red herring. Just as the switch to "hydrogen economy" (remember that?) was before it. Both require huge investment, new infrastructure and will not lead to a post-oil economy. The hydrogen economy was promoted principally by both automakers and oil companies as a stalling strategy to avoid having to change the way they currently do business. Oil companies were also aware in the unlikely event that the hydrogen economy did take off (with huge taxpayer subsidies) that they would be supplying hydrogen produced from natural gas which they were already profitting from. The automakers sat around lamenting the fact they couldn’t start to build cars as there are hardly any hydrogen filling stations and the energy companies would not open commercial hydrogen filling stations as there is no demand for them. While appearing to want to do something, both the automakers and energy companies continued for a few more years with business as usual.


    The Nissan Armada promoted on the E85 fuel site - with no fuel economy figures indicated

    The campaign for E85 fuel is somewhat similar. The automakers are eager to produce flex fuel vehicles which require a relatively cheap modification to the highly profitable gas guzzling SUVs they already produce. By backing E85 fuel they can continue to produce the highly inefficient vehicles while appearing to be green (as seen in GM's Live Green Go Yellow campaign). As GM admits the consumer can choose “to operate on gasoline or on a blend of 85% ethanol and 15% gasoline. So, you can choose the fuel that's best for you. That's good to know, because E85 fuel is not yet widely available.” In other words in the vast majority of cases your new flex fuel vehicle will still be running on regular gas. Charter members of the National Ethanol Vehicle Coalition (NEVC), which promotes E85 fuel, when it was set up in June 2000 include GM, DaimlerChrsyler, and Ford.

    Meanwhile E85 fuel is also been promoted by organisations such as the National Corn Growers Association, as well as regional and state corn growers organisations, associated agribusinesses and biofuel companies. All of which have a commercial interest in promoting E85 fuel. According to the Center for Responsive Politics, a clearinghouse on political donations, the agribusiness sector has funneled more than $190 million into federal election campaigns since the 2000 election cycle. In the NEVC’s bylaws its purpose is described as to "ensure that as decisions regarding the future of America’s use of alternative forms of transportation fuels are being made, ethanol has a role in the nation’s alternative transportation fuel market and support the expanded use of ethanol" and to "advance legislative proposals" to this effect. This seems to be regardless of whether ethanol/ E85 fuel is the best or is even a good solution to our energy challenges.

    As the Engineer Poet points out in this post, burning fuel for transportation is very inefficient way of using energy. Whether you are fed up with the current use of petroleum for transportation for environmental, political or financial reasons E85 fuel is simply not the answer. What we need is a step change, as represented by moving from using gas burning vehicles to electric vehicles.

    To encourage this, I urge you to sign this online plug in hybrid campaign asking automakers to produce plug-in hybrid electric vehicles (PHEVs).

  • Why Alternative Energy?

    Posted: 2006-07-17 10:00


    A poll carried carried out for the BBC World Service of nearly 20,000 people from across 19 countries found wide support for alternative energy strategies.

    The poll illustrates a perceived triple threat from the way the world produces and uses energy.

    Majorities across all 19 countries indicate that citizens fear:

    the climate and environment are being harmed
    that the global economy will be destabilised
    that competition for energy will lead to greater conflict

    Some eight out of 10 of those questioned were worried about the threat to the environment. In Australia, Great Britain, Canada and Italy the level of concern topped 90%.

    Doug Miller, president of the poll firm GlobeScan, said: "What's fascinating is that in the midst of historically high energy prices and geopolitical tensions, the number one energy concern in every industrialised country we surveyed is the environmental and climate impacts."

    Creating tax incentives to encourage the use of alternative energy sources such as wind and solar power found favour with 80% of respondents.

    But there was lukewarm support for more nuclear energy to reduce reliance on fossil fuels. On average, 49% were in favour of building more nuclear plants.

    Majorities of 60% or more in 18 of the 19 countries polled said they feared energy shortages and prices would destabilise the world economy.

    The least concerned was Russia, a major oil and gas producer, which benefits from higher prices.

    Both US and EU leaders have warned Russia not to use energy as a tool of foreign policy. Earlier this year, the nation's monopoly, Gazprom, cut off gas supplies to Europe during a price dispute with Ukraine.

    Some 73% of those questioned were worried that energy shortages would lead to greater conflict among nations.

    In total, 19,579 citizens were interviewed in Australia, Brazil, Canada, Chile, Egypt, France, Germany, Great Britain, India, Israel, Italy, Kenya, Mexico, Philippines, Poland, Russia, South Korea, Ukraine and the US.

    Polling was conducted for the BBC World Service by polling firm GlobeScan and its research partners.

  • $4b Investment in Wind Power by BP Alternative Energy

    Posted: 2006-07-17 09:15


    BP is making its first major investment in wind power with a joint venture that will lead to a major expansion of its generating capacity.

    The oil company announced it had entered a five-year supply and development agreement involving five wind power projects in the US with Clipper Windpower.

    The news sent Clipper shares up 80p, or 28 per cent, to 362.5p in London. The projects, with an anticipated total generating capacity of 2,015 megawatts, are situated in New York, Texas and South Dakota.

    BP has also secured a mix of firm and contingent orders of up to 2,250 megawatts of additional Clipper wind turbines in its global wind energy portfolio, the companies said.

    BP launched BP Alternative Energy to focus on solar, hydrogen and wind power but its wind operation has up to now been confined to two projects with a combined output of only 31 megawatts.

    Steve Westwell, the chief executive of BP Alternative Energy, said: "We believe the Clipper turbine is a breakthrough in reducing the total cost of renewable energy and we are pleased to be the first large customers for this innovative technology."

    This is thought to be the biggest single investment in wind power estimated at $4 billion US dollars.

    The announcement, came in the same week that the British government published its energy review and a telephone poll found that 79% of respondents thought solar power and 76% wind power were the best investments in electricity generation for the UK.
  • Alternative Energy Inspires Young Scientists

    Posted: 2006-05-15 01:41


    In Indianapolis a number of the 1,500 young scientists competing in the International Science and Engineering Fair for $4 million dollars in prizes and scholarships pursued alternative energy innovations.

    Seventeen year old Allison Wilson from Stuart, Iowa, won $11,000 in scholarships by making ethanol fuel from prairie grass.

    Renewable energy also inspired 17 year old Brian Sutterer of Terre Haute, Indiana, who generated electricity using the difference in temperature above and below ground (geothermal energy).

  • Ethanol Fuel in South Africa

    Posted: 2006-05-14 13:15

    photo (c) 2005 Julia Freeman

    Tumi Makgetla reports in South Africa's Mail & Guardian that while an interest in alternative energy and green politics is often seen as the preserve of the chattering classes, working-class people in Johannesburg's inner city are already using renewable energy in their homes.

    On a pavement in Joubert Park in Joburg (how Johannesburg is commonly called), shoppers cluster around Tumelo Ramolefi’s stall exclaiming and asking questions about his products. Ramolefi is not selling the usual inner-city hawker stock of facecloths and socks, or "smileys" (boiled sheep heads) and "runaways" (pigs’ trotters). Instead, it is his display of innovative renewable-energy gadgets that attracts the attention of passers-by, and often turns them into converts to the green-energy cause.

    His bestselling items are ethanol gel stoves and lamps, which offer a healthier, safer and more efficient fuel alternative to paraffin or coal fires.

    Ethanol gel is a renewable form of energy made by mixing ethanol with a thickening agent and water. The ethanol is extracted through the fermentation and distillation of sugars from sources such as molasses, sugar cane and sweet sorghum or starch crops, like cassava or maize.

    Ramolefi sells ethanol gel products and appliances for GreenHeat South Africa, which has branches in Durban, Jo’burg and Cape Town. The stoves and ethanol gel -- produced from sugar cane -- are manufactured in Durban. A two-plate stove sells for R160 (approx. $25 USD) and a lamp for R50 (around $8).

    "This stove is number one," said Maria Ndlela, who works in a recycling centre in Joubert Park and has owned her stove for two months. She says it is easy to use and, while paraffin is cheaper than the gel, the gel is more cost-efficient in the long run. Five litres of gel costs about $9.70 and paraffin costs approximately $3.55 for the same amount. "Gel lasts. If you don’t use it too much, five litres of gel takes you a month to use, but five litres of paraffin lasts only three days."

    Ndlela says an added attraction of ethanol is that the paraffin price fluctuates. “The price of paraffin is going up and down, up and down with the petrol price,” she said, “So now I’m forgetting about paraffin.”

    “What I like about the stove is that it will conquer our unreliable electricity,” said Florah Thulare.

    Safety is also a big selling point in favour of ethanol products, particularly for those who use coal or paraffin for heat and cooking. Paraffin stoves, which explode or are easily knocked over, cause fires, and poor ventilation can lead to asphyxiation.

    "Coal can actually kill you during the night," says Ramolefi. "In this coming month, we know people are going to die, but there’s no campaign."

    Gel fuel burns with a carbon-free flame, so it does not cause respiratory problems such as asthma, which can be caused by emissions from paraffin, coal and wood fuel. The gel also does not produce any smoke or smell.

    Gel fuel will not ignite if spilt like gas or paraffin. The gel is non-toxic and thus is not poisonous if swallowed by children. The stoves are designed so they will not fall over if bumped and the stove’s legs allow it to slide when pushed instead of toppling over. Even if an ethanol lamp is overturned, the gel will extinguish the wick.

    The stoves are designed for cooking, but about half of his customers buy them as heaters, said Ramolefi.

    Ramolefi has sold about 70 stoves in the past eight months and hopes the market will grow and prices will consequently drop, making the stoves more affordable for the poor.

  • Austin Energy Excels as #1 Green Energy Electricity Utility in America

    Posted: 2006-04-15 04:00


    UPDATE: This is a list of the top ten green energy programs in the United States with the latest December 2005 figures and links to these electric utilities. One of the biggest differences we can make is to switch to "green energy" - energy generated from 100% renewable sources. Florida Power & Light is a new entry into the top ten at number four. The company recently announced the construction of the largest solar array in Florida on the site of a closed landfill in Sarasota. The 1,200 photovoltaic solar panels are each about 31 inches wide and 63 inches long. The facility is to be more than 28,000 square feet, or about half the size of a football field. "We sought a location that had a ground site large enough for 250 kilowatts of photovoltaic panels," said Jeff Bartel, FP&L VP of external affairs.

    If you live in a part of the United States that is not served by an electric utility on this list please see this Map of Green Energy Providers by State.

    As our energy challenges are global I appreciate every assistance in compiling a similar list of renewable energy providers in other countries. Feel free to email or leave a comment.

    Returning to the United States, Austin Energy has shown its commitment to renewable energy by topping the list. The U.S. Department of Energy said Austin Energy's Green Choice program sold more than 334 million hours of renewable energy last year.

    More than 350 businesses in Austin get their power from renewable sources as an alternative to fossil fuels.

    Austin Energy uses electricity from 61 West Texas wind turbines.

    Here's the top ten green energy programs in the United States (as of December 2005).

    1. Austin Energy -
    areas served include Austin, Texas
    green energy from Wind Power, Land Fill Gas, Small Hydro -
    435 MWh/year

    2. Portland General Electric (PGE) -

    MWh/year = million kWh/year rounded down

    List of Green Energy Providers by State

    One of the single biggest ways we as individuals can encourage the use of alternative energy and help aid the transition to a post fossil fuel age is to buy electricity partly, or preferably completely, generated using alternative energy.

    Switching your electricity utility provider may be as simple as requesting a form or filling one in online. That's exactly how I switched to 100% renewable energy (generated mainly from wind power with some solar power and small scale hydro thrown into the mix). Renewable energy options are available throughout the U.K. and in many other countries.

    To find out if you can switch to renewable energy in your area look on your search engine of choice for "green energy", "green power" or "green electricity". You may also need to add your location to the search. If your local utility doesn't provide a renewable energy option yet, email or call them and ask why.

  • Mixed Signals & Federal Funding for Alternative Energy Research

    Posted: 2006-03-09 11:22


    There have definitely been some mixed signals on alternative energy research recently. At the same time President Bush's State of the Union address called for a 22 percent increase in federal spending to develop alternative energies, dozens of staffers and contractors for the National Renewable Energy Laboratory in Golden, Colorado, were being laid off.

    The disconnect was a political embarrassment for the president, so federal officials restored the laboratory's funding, rehiring the workers who had been laid off just in time for President Bush’s scheduled speech at the NREL.

    In his speech the President acknowledged the confusion, “I recognize that there has been some interesting mixed signals when it comes to funding," President Bush said.

    This comes at a time when a new national public opinion survey demonstrates overwhelming public support in the United States for government policies and investments that will support development of alternative energy sources. The survey of 1,000 registered voters was conducted by Public Opinion Strategies of Alexandria, VA, for the Energy Future Coalition. The survey’s findings included:

    According to the survery there is nearly unanimous support for a national goal of having 25% of the United States domestic energy needs met by alternative energy by the year 2025. Ninety-eight percent of voters see this goal as important for the country, and three out of four (74%) feel that it is "very important." Ninety percent of voters believe this goal is achievable.

    Similar majorities support government action to encourage greater use of renewable energy. Eighty-eight percent of voters favor financial incentives, and 92% support minimum government standards for the use of renewable energy by the private sector.

    Nearly all voters (98%) say the costs, such as the cost of research and development and the cost of building new renewable energy production facilities, would be worth it to get the United States to the 25% by 2025 goal.

    Voters consider energy to be an important issue facing the country, rating it similarly with health care, terrorism and national security, and education, and ahead of taxes and the war in Iraq. Half (50%) of voters believe America is headed for an energy crisis in the future, and 35% believe the country already is facing a crisis.

    So just how much is the United States government spending on alternative energy research? After the 22% increase the budget will stand at $771 million. This amounts to less than one percent of the $55,000 million the federal government spends annually on research, nearly half of which is devoted to healthcare.

    It’s time for action.
