    It's encouraging to see that alternatives are being developed. At the same time I think more should be done to reduce consumption which has the added benefit of reducing harmful emissions. The push for biofuels, while politically expedient, creates problems of its own. We are already witnessing its impact.
    The use of waste products in biofuel production makes much more sense as it then becomes a form of recycling.

    I really do not know much about the reality of ethanol from citrus, but I hope it is not as big of a disaster as ethanol from corn. The largest winners from the manufacture of ethanol from corn are the corn farmers. This year even the price of US wheat to American wheat farmers went up to $5.65 per bushel partly because of the tremendous amount of acreage that was diverted by wheat farmers to corn production so they could get in on the corn cash train. Last year I sold my wheat for $3.75, per bushel this year $2.00 higher. It was nice but still it is a rip off of the general public. Food pricing is up also because of ethanol. Corn products are ingredients in tens of thousands of the nations food products. CBS television's special on ethanol, showed that the total amount of energy expanded in the manufacture ethanol is about equal to the amount of energy that ethanol provides. Just a trade off. Lastly, a tremendous amount of energy is used in just moving ethanol from the farm field to the consumer. Ethanol cannot be shipped by pipeline like oil can. Ethanol has to be shipped by truck. In my opinion, the last item that should be used to manufacture fuel is the people's food supply. How dumb is that? A win fall for the corn farmer, bad for the public. Another US government "great" plan. - Millet

    Even that can be damaging to the crop producer - what is burnt for biofuel can no longer be composted to return the nutrients to the next crop, as it has been in the past. So it results in a significant drain on soil fertility and condition.

    Actually, ethanol does not contain any of the macronutrients that were in the corn or citrus waste-- the nutrients all end up in the yeast and sludge that is left after the ethanol is removed. In the case of corn, many of the plants that produce ethanol are turning the waste directly into cattle food and in many cases feedlots are built next to the plants.

    I have heard that conversion of corn to ethanol uses almost as much energy as it produces, but I think to get that figure they even included the energy it takes to heat the farmers house. Sugar cane is more efficient and Brazil has become energy independent based on ethanol, so it can be done.

    I think the use of waste products for fuel is a good move. If we can extract the orange juice for us, ferment the waste, extract the ethanol for fuel, and feed the waste to cattle, then use the manure for improving the soil we will have gotten pretty good use out of an orange.

    But the fact remains, that nutrients are removed from the site where the crop is grown, and not replaced there (whether they go up a chimney as smoke, or into a cow as cattle feed).

    It is a real concern in UK forestry plantations, where the brash (small branches and foliage) is currently left to rot on site after the timber harvest, providing important nutrition for the next rotation of trees, and also cover for wildlife. If all this brash was harvested too, the nutrient status and organic content of the soil would fall to such an extent that the subsequent crop would have very poor growth. The brash contains most of the nutrients on the site; very little is removed in the logs which unlike the leaves are nearly pure cellulose.

    Skeet, ........." get that figure they even included the energy it takes to heat the farmers house"......Skeet my good friend .....PLEASE!!!

    Ethanol from corn is a GREAT IDEA if your a corn farmer, and I will have to admit it also helped me as a wheat farmer, but it is a BAD DEAL to the general public. It is the general public that will be forced to pay the bill every time they go to the store. Using one's food supply for fuel, is dumb. Further, ethanol certainly is NOT a very efficient fuel. It was announced just last week that a large range of food items will be increased due to the increased price of corn sweetener, corn starch and the further decreased availability of other cereal crop due to conversion to corn growing. Heaven forbid, it was also announced that the price of beer will also go up due to the fact that barley pricing is taking a jump because barley producers are also converting to corn and jumping on the corn gravy train. As for the conversion of citrus to ethanol, it will produce such a minute percentage of the total fuel required, it is almost not worth mentioning. MichaelF USA farmers rely totally on chemical fertilizers for crop nutrition, not returned waste. For wheat the fertilizer used is 99 percent Anhydrous Ammonia injected into the soil prior to seeding. Reliance on returned waste is a good method for US farmers to go broke. - Millet

    Millet, I am going from memory, but I remember hearing an interview with a scientist that wrote an article saying that the net energy yield from corn was "zero". In the interview, it was revealed that to get to the "zero" figure, the scientist had included the energy required for growing the corn, transportation, distillation, and "even the energy required to heat the farmers home". Personally I do not believe that the yield is zero, but I can accept that it is not very efficient and we need to find other sources of energy. Brazil has become energy independent based on ethanol from sugar cane.

    The price of corn and soybeans has gone up because the energy value in those crops is worth more since oil cost have gone up--it will only get worse if we do not come up with alternate sources. Citrus waste is a small amount, but it all adds up-- waste oil from resturants, methane from landfills, using wood chips from tree trimming---.

    Just yesterday I heard on 850 KOA radio (the strongest and most listened radio station in the Rocky Mountain western states of the US) that a group of scientists are now calling for a warning about global cooling !!! I also heard a report on the same station concerning the posting Junglekeeper posted above. How many scientific scares have come and gone in the last 15 years? Natural Global warming has happened many times in past ages. Man caused global warming, color me quite SCEPTICAL. I could not care less about (1) 319 years to recoup the carbon emissions to create diesel-soybean plantations, (2) 423 years to pay off palm oil plantations, (3) corn-bio fuel production targets would be 167 years. If some one want to plant a palm oil plantation, I say fine, plant it, if a company wants to put in a diesel soybean plantation, fine build it. Some day an environmentalist probably will come up with the number of debt years it produces to fix the pot holes on the highway. This latest scare will go the way of all the other scares. - Millet

    There is no question that man has influenced
    the impact of cyclic periods of global warming.
    Even today people are tapping into volcanic
    warmed glacier melt lakes as primary water
    sources, when before they could not. With the
    absence of the lake water now, we then get to
    see and read about the lake's disappearance
    on the television newscasts and in some
    documentaries as being directly related to
    global climate change. The climate can be
    impacted by the loss of the water but in a
    passing comment we may learn that the
    water all was siphoned off and was used
    for consumptive purposes. In this case the
    global climate change purveyors were people
    and the one consistent is that the people that
    used up the water are permanent and the lake
    was not.

    I think ethanol production was always meant
    to be a short term benefit until we get our
    act together and figure out more ways to
    work on clean burning or cleaner combustion
    energy. The current ethanol production is
    not meant to be a significant lowering of
    the amount of imported and domestic oil
    production as more and more people are
    driving cars than before along with the
    increased number of people needing
    heating oil still in major sections of
    North America. As far as global warming
    is concerned that all oxygen emitters and
    liberators contribute to global warming,
    then it is safe to say that just my breathing
    contributes also. We have become rather
    ridiculous now in what some researchers
    are presenting as evidence with so much
    subjective postulatization going on rather
    than actual objectively reasoned and unified,
    applied theory.

    We have to define what Citrus waste is
    and how do we assess what is wastage.
    I think the peel aspect for generating
    ethanol pales in significance as opposed
    to using whole fruit to yield ethanol
    or "dieselhol" We get more bang for
    our buck using the whole fruit which
    opens the doors to biomass a huge
    amount of discarded fruit such as
    overripe fruit that cannot be shipped
    or processed or fruit that cannot grade
    out due to marketing order restrictions
    and constraints. On one hand I like the
    whole idea of being able to render some
    use to much of the pome and stone fruit
    that goes to waste by using them to
    generate something useful in return
    as opposed to simply being discarded
    and either collected and buried or
    burned or left on the ground to rot.
    If we go back to thinking in terms of
    cultural control for some insects and
    diseases then we surely do not want to
    let the fruit rot on the ground and then
    be faced with using a pesticide spray
    the following year all because we chose
    to be remiss in our crop clean up.

    There are lots of issues in using
    biomass generation and one of
    them here has been the idea that
    we liberate pollutants into the
    air which is why some biomass
    plants were put on hold for a
    length of time until the "greased"
    politicians in our state legislature
    decide either to not let the biomass
    plants function, let them go online
    due to air compliance quality
    factors or let them remain as is
    to regenerate energy for electrical
    users once again. In this state
    we do not get to vote on what
    we want to do with renewable
    resources and other energy sources
    such as proposed clean burning
    coal and even cleaner emitting
    nuclear power. We always get
    to see, hear or read of someone
    with an environmental or bought
    off agenda telling us of a better
    way to do things, yet we never are
    told in any definable terms what
    those better ways are that are
    designed to impact the rest of us.
    We still can see every now and
    then the guy running around town
    in a Hummer spouting off on the
    evening news that GM can be
    producing that same car with 40
    miles per gallon capability, yet
    for him that 12 miles to gallon
    gas guzzler fits his current day
    lifestyle needs just fine.

    Say whatever you want about
    ethanol. No one talks of the
    tax breaks that people got to
    build the plant or all of the
    subsidized corn being used
    to supply the ethanol generation
    or the taxpayer funding that
    bought the land to build the
    subsidized plant and then
    be told that there has to be
    a guaranteed price in return
    or they will close down the
    plant and leave us holding
    the bag after all of the higher
    ups all move to resort areas
    and be pampered for the rest
    of their lives at our expense.
    In that case we are not looking
    at a net zero, we are looking
    at a net deficit but we were
    looking at that all along anyway
    that we get to pay for again and
    again just for some short term
    energy relief.

    I think Florida Citrus Mutual
    needs to stand back from their
    intent and reason that private
    enterprise is the way to go,
    rather than putting all of their
    peels into one person's basket.
    Then again as we saw out here
    with solar that others involved
    in energy generation will buy
    up the privateers and quickly
    expunge their competition. It
    took several years for solar to
    make a comeback here and it
    was in part due to an energy
    producing company that felt
    the need to harvest the sun as
    a long term approach to sustaining
    their very existence. Give them
    enough time in their efforts
    to educate people with wind,
    solar and water generated
    electricity and they will have
    a significant impact in how we
    do things. No, not all energy
    producers are looking solely
    at the short term buck and for
    this I, for one, do appreciate
    what PG&E have done here
    and are trying to do. Yes, they
    are in the business to make money
    but at the same time they have
    a long term outlook that few
    others have and they do not
    cow-tow to their stockholders
    short term interests either. Yes,
    they can do more to advance
    renewable energy but when we
    go to the nearest office and see
    people in line with $400 energy
    bills that they only pay $200, then
    we can better reason that what
    they are doing is not all about
    the money. They do not have to
    give any low income person a
    price break on anything if they
    were the diehard, in your face,
    we do not care, business that a
    few misguided malcontents have
    written about online. We may
    not always like them in what they
    do but we better learn to respect
    them for what they have done and
    continue to do. What price tag do
    we put on service that is always
    there, right now, even when the
    going for them at the time can be
    rather difficult for them to deal
    with?

    Jim said, ....."There is no question that man has influenced the impact of cyclic periods of global warming."....

    Actually, there are an untold number of questions remaining, of man's "influence". Myself, I would rather see the citrus pulp continue to be used for feeding livestock, instead of being used in yet another heavily subsidized venture, and another draining of the American tax payer. The college text book "Citrus Growing in Florida" says that the use of the peel for livestock feed, is actually quite profitable, and certainly is a benefit to the Florida rancher. Certainly, more of a benefit to the Florida ranching community, than the micro drop in the bucked of over subsidized fuel to the Florida motorist. On the 1st Earth Day in 1970 the US depended about one quarter on foreign oil. With the increasing environmentalist's demands on restrictions of domestic oil production, insuring that increased domestic demand must be met with other than domestic supply, this dependence is now 60 percent. The environmentalist say, "We need to eliminate our dependence on foreign oil....but no drilling here"??????????? - Millet

    Thought sure I was going to catch heck from a
    host of angles yesterday while spending 6 hours
    mowing the backyard lawn. I had a lot of time
    to do some thinking about what I had posted.

    There is and has been periods of global warming
    along with periods of global cooling. Historical
    records will indicate this. We have evidence that
    this is or may be happening also in newly discovered
    dwarf planets as well..

    I like the hard facts such as drilling core samples
    in Greenland and then determining oxygen content
    then in periods of the past as opposed to now.
    Seeing glaciers disappear before our eyes does
    lead to a conundrum but do we ever ask did
    this happen before and we just do not know
    about it? Funny thing that along the way we
    learned Greenland in the past was much warmer
    than it was in the last century and perhaps even
    the previous millennium. We have recorded
    data that tells when Germany was much warmer
    than it has been since the later 1800's. Warm
    enough to be growing Citrus in vast expanses
    and other cold sensitive crops, such as what
    we now call truck crops, vegetable crops, in
    ground. We cannot deny that Germany for
    a century or two longer was indeed warmer
    than it has been in more recent times. Just
    look what happened to all of the wine grape
    growing regions of Germany when they used
    to be everywhere in Germany.

    Florida Citrus was expected to face a quarantine
    in which no fruit can be shipped out of state and
    no Citrus could come into Florida either. I was
    surprised from being here on the "left coast" that
    this did not happen. We know of Florida Citrus
    that was shipped to Canada and we also saw
    Citrus nursery stock from Florida being shipped
    into Oregon of which none of those plants can
    come into California. The only way to ship under
    such an imposed quarantine that we've faced in
    the past is to fumigate the fresh market fruit for
    overseas consumption (cannot talk about the fact
    that the fumigant is a known carcinogen either)
    or process all the fruit in Florida and continue on
    selling juice and hope that another country or two
    or three does not flood the market with their juice.
    Florida with the canker issue was facing pretty
    much a county by county quarantine in which
    fruit from unaffected counties could be shipped
    out fresh sans the fumigation but when Florida
    was hit with a Citrus Greening quarantine then
    the entire state was to be under that same type
    quarantine as we have been here. The major
    difference is that our state imposed quarantine
    is much more strict than a Federal imposed
    quarantine is. Just ask Sunkist if you do not
    believe me. They remember the Med-fly and
    what had to be done to ship Fresno, Tulare
    and Kern County Citrus to Japan with an
    ethylenedibromide fumigation before those
    fruit could be shipped out but those same
    fruit could not be shipped to any other state.
    We do not see that in Florida or we are not
    being told of it and I do think that Canadian
    consumers that are seeing Florida Citrus
    come into them do have to right to know
    about it.

    So, with the two quarantines that Florida was
    to be subjected to that all fresh market Citrus
    was to stay in Florida that there was an "out"
    for all of the perishable fruit and that was to
    do something with them and lo and behold
    thanks to a few Universities that ethanol
    and we already knew that electricity can be
    generated from biomassing the fruit. The
    grower is going to pay for the picking
    whether the fruit is going to market or is
    processed or goes to waste. Out here
    with Navels we take a beating if the fruit
    is not of grade size to be shipped and goes
    to juice. Our return does not even come
    close to what the picking costs are, actually
    the price we get is an insult but if we can
    have a choice of having the fruit go to juice
    for penny's on the dollar or let the fruit go
    to biomass for free with no return, I'd choose
    biomass every time. We do not have to have
    our fruit go towards the making of ethanol
    we can choose having the discarded fruit go
    towards biomass generated electricity instead
    and this would be my personal choice but I do
    not have that choice. Even the people I know
    running or were running biomass facilities
    near the area were all put on hold, even at a
    time when we had electrical power grid
    problems in this state the led to some major
    selected power outage blockages in select
    metropolitan areas that some people later
    called brown outs. Well, none of these
    brown outs happened on their own. A
    quick flick of a switch from a power grid
    central station turned the power off to
    prevent the power reserves in this state
    from going to less than 3%. 5% power
    reserves is critical but less than 3% is
    too close to a statewide power grid
    meltdown.

    We can get more from hydroelectricity and
    geothermal electricity here to coincide
    with solar and wind generated electricity.
    We can also invest in more clean burning
    coal as well as look into clean nuclear
    fuel ( I want to know how do we render
    the waste material harmless before we
    get there with nuclear but that is just me).
    The naysayers still are quick to comment
    that we will be using petroleum oil to
    help generate much but not all of the
    electrical output needed to supply what
    we have now and what we will have later.
    The problem at this time is what we will
    have later with more and more cars on
    the road, more homes, more apartment
    dwellings, more and more land taken out
    of production.

    The proposed notion back in the 60's was
    that we would in time be working at a net
    deficit in that we were facing the prospect
    of using up more natural resources faster
    than they can be replenished. We are there
    now but as long as we find more oil reserves
    and those same reserves are not domestic
    reserves then we are at the mercy of the
    oligopoly gas producers that get 50 cents
    on the barrelhead for each and every barrel
    of oil they help produce from the oil
    producing areas. So when we read of
    $100 a barrel oil, who do we think gets
    half of it? Oil in of itself in an enigma.
    Demand can be down and the price goes
    up. Demand goes up and so does the price
    to us end consumers. Supply goes down
    and the price goes up and when supply
    goes up the price stays the same. Not
    much different than credit card lenders
    in that the federal rate to borrow goes
    up and so does our rate of interest and
    when the feds cut the rates to the lenders
    our rates go up again. The problem that
    I foresaw as it was happening that led me
    to know we were in big trouble was who
    is now in change of the gas company
    credit card billing statements. Who are
    we sending our payments to and guess
    what, they are the principal players in
    the credit card lending schemes. With
    those players involved headed by a oil
    conglomerate that does not have to pay
    US taxes since they are a foreign owned
    company, the realism is that unless we
    start to see some real fluctuations in
    oil output there will be no real desire
    to move away from having imported
    oil continue to come in. In that we
    have players involved that will not
    allow alternate fuels to come about
    and will expunge upstart companies
    like what was done to solar here and
    why the wind machines at Altamont
    Pass were rendered useless after
    they were privatized for company
    tax write off purposes in the early
    90's.

    We are not going to win Millet. You
    know of coal in Colorado going somewhere
    but it cannot come here. We have the
    ability to light up the sky with solar in
    vast desert areas in the southern and
    Mojave desert areas and then we surmise
    that all those solar panels we see out in
    the middle of nowhere are generating
    electricity to the highest bidder instead
    of going to nearby cities and the larger
    populated metropolitan areas of this
    state. Makes no sense to me but
    it will to those that own those solar
    panels and why it is that we do not
    see more of them. The same issue
    I had years ago with hydroelectricity
    in that virtually every dam up this
    way and farther north have the ability
    to generate electricity, why aren't we
    doing it then if we have all the needed
    components to do so already right
    there and ready to go without too
    much worry of NIMBY interference.
    A great friend of the family had a
    dam named after him for his lifelong
    work with California water that was
    put in just to generate electricity.
    The paltry output from that dam is
    what irritates me but I've grown to
    yield a little in my hopes and
    expectations.

    Jim, two items. Very little electricity in the USA is generated by using oil to power the generators. Just about all electricity is generated using coal. Second, the high price that the country is FORCED to pay for FOREIGN oil is not our problem. Unreasonable environmentalists demands is the nations problem. - Millet

    Re: O.T. to a large extent.

    I think the links show that we do things a
    little differently out here than the rest of
    the US. What you want to know is what
    is used to start up the turbine engines and
    for that we use fossil fuels for the most
    part.

    I know of a "clean" burning coal plant
    about five miles Southeast of Lemoore
    Naval Air Station that waited a long time
    to go online due to the legislature not
    wanting to grant them a license due to
    air quality concerns to go online. A
    governor stepped in and let them go
    online, so we do have some "screened"
    coal (not just any coal) that is coming
    here but not much of it as of yet. As
    we can tell from the second link that
    a lot more solar energy is produced
    here than is listed for electrical output.
    Much of it is privately owned, not
    corporate owned per say in the sense
    that it is not the bona fide power
    companies in this state that own them.
    We are even using solar now to run the
    street lights along certain notorious,
    fog stricken roadways and we should
    see more of them in time (I sure hope
    so as the stretch from Sacramento to
    Bakersfield (my home area) can be
    a real bearcat to drive at night) A lot
    of the electrical power we see among
    creeks, streams and smaller rivers to
    monitor water flow are run by solar
    now as well. We do not need to run
    diesel to utilize solar photovoltaic
    cells and that is a huge advantage in
    the battle with the few zealots that
    are anti everything as long as it does
    not pertain to or impact them but does
    to the rest of us.

    Jim, one thing I agree 100 percent with you is that California does do things different than the rest of the country. Especially different than the rest of the western states. As this is a citrus forum I think I will stop at this point. Millet

    The thread title encompasses more than just
    Citrus, so a discussion on energy was bound
    to come into the thread as being part of the
    original thread post and link. I will stay on
    the sidelines now after a quick edit to my
    last off topic post.
