Corn Can’t Solve Our Problem – washingtonpost.com

If every one of the 70 million acres on which corn was grown in 2006 was used for ethanol, the amount produced would displace only 12 percent of the U.S. gasoline market. Moreover, the “new” (non-fossil) energy gained would be very small — just 2.4 percent of the market. Car tune-ups and proper tire air pressure would save more energy.

Proper tire pressure is not sexy, and does not lead to billions of dollars of profits!

The net effect is that ethanol from corn grown in the Corn Belt does increase atmospheric greenhouse gases, and this increase is only about 15 percent less than the increase caused by an equivalent amount of gasoline

Corn is such a boondongle, it’s amazing what the ADMs and Monsantos of the world can do.

This means that when tropical woodland is cleared to produce sugar cane for ethanol, the greenhouse gas released is about 50 percent greater than what occurs from the production and use of the same amount of gasoline. And that statistic holds for at least two decades.

Brazil will not solve all your problems (unless they’re samba related!). Increased demand for ethanol from Brazil could lead to clearcutting of the rain forest/other fallow grassland.

Across the full process of growing high-diversity prairie hay, converting it into an energy source and using that energy, we found a net removal and storage of about a ton and a half of atmospheric carbon dioxide per acre. The net effect is that ethanol or synthetic gasoline produced from this grass on degraded land can provide energy that actually reduces atmospheric levels of carbon dioxide.

It’s a very well written article.

    Smoking bans in North Carolina?

    Byoliveridley

    After this morning’s post about Tennessee, I got curious and wanted to see what we were doing in North Carolina on smoking bans. So, I looked up my very own NC General assembly homepage and used their full text bill search function (key word smoking!). Here’s what I found.

    In the State Senate

    Great! Senate Bill S635 will ban smoking in all public places indoors except in tobacco shops, designated smoking rooms in hotels and for “research”. Follow the progress of this bill using the bill’s very own rss feed!

    In the House

    Not so good, House bill H259 has been referred to committee. But it has giant loopholes for all bars and “private clubs”. It has its very own rss feed too.

    Observations

    1. It is good to see that my representatives Kinnaird (we share a yoga class on Monday nights!) and Insko are co-sponsors on the bills. But I live in that bastion of progressivism (in the South, anyways!) Chapel Hill/Carrboro, so this is pretty unsurprising!
    2. My question to the House is this: Why are bartenders, employees of bars and private clubs, and patrons of such establishments considered not worthy of protection from second hand smoke? As someone who goes out drinking often, this is where all my exposure to second hand smoke occurs.
    3. Kudos to North Carolina for designing an accessible and easily searchable bill repository complete with rss feeds, way to go!

    Once I hear back from Sen. Kinnaird on the prospects of legislation this session, I’ll be sure to post about it.

    Update: See this. The House and Senate bills have gotten a lot closer, and most of the loopholes are gone.

  • Coal is Evil, part 1201010

    Byoliveridley

    Note: When people say “clean coal”, they are referring in part to all the actions taken to limit particle and ash emissions out of the smokestacks. This is done in a variety of ways including washing the coal to remove inorganic ash components, trapping the particles using electrostatic precipitators, etc. What this leaves you with is very toxic coal ash, and very toxic acidified water loaded with the coal wastes it was used to remove.

    Now you can pretend that this is somehow cleaner, and it is, to an extent, because you have concentrated the pollution by isolating it and not letting it disperse into the atmosphere. However, if you then dump the waste into unlined landfills, you completely defeat the whole point of the exercise. This very extensive report written by the Clean Air Task Force and Earth Justice looked at streams in Pennsylvania and found a ton of heavy metal pollution.

    Coal is neither cheap, nor clean if you have to deal with all the pollution and pay for it, and we did not even have to get to that whole other pollutant, CO2!

    <Pennsylvania Groundwater Contaminated By Coal Ash

    Disposing of coal ash in mines is contaminating water supplies throughout Pennsylvania, according to a report released today by the advocacy group Clean Air Task Force and the nonprofit, public interest law firm Earthjustice.

    In 10 of 15 mines examined across the state, groundwater and streams near areas where coal ash, or coal combustion waste, was placed had levels of arsenic, lead, cadmium and selenium and other pollutants above safe standards.

    ‘Disposing of coal combustion waste in these mines is threatening water supplies all over the state,’ said Jeff Stant, director of the Pennsylvania Minefill Research Project at the Clean Air Task Force. ‘If the Pennsylvania Department of Environmental Protection won’t act now to stop these dangers, the U.S. EPA should step in to protect the residents of Pennsylvania who live near coal ash mine fills.’

    The Pennsylvania Department of Environmental Protection has refered to the ‘beneficial use’ of coal ash in these active and abandoned mines, claiming that the practice limits the outflow of acidic water from mines.

    This study found the opposite was true – in six of the nine permits that used coal ash to treat acid mine drainage, acidity levels increased, leaving the mines more acidic at the end of monitoring.

  • US, India and China Talk Climate

    Byoliveridley

    The Obama administration is hoping to win new commitments to fight global warming from China and India in back-to-back summits next month, the Guardian has learned, including the first Indian emissions trading scheme.

    The US hopes the new commitments will breathe life into the moribund negotiations to seal a global treaty on climate change in Copenhagen in December, by setting out what action each country will take. But many observers say such bilateral deals also risk seriously weakening any Copenhagen agreement by allowing the idea of a global limit on greenhouse gas emissions to be abandoned.

    The Guardian

    So, as part of Blog Action Day 2009, which is focusing on climate change, I bring you news that the US administration is back, taking some kind of a leadership role in climate change by talking to India and China. The notion that somehow what the US, Europe and Canada do in response to climate change is pointless because China and India are not going to participate is misleadingly inaccurate, sometimes deliberately so. I had written in June about India’s very ambitious solar policy, and China has similar, fairly comprehensive programs on climate change.

    The concern that bilateral talks will somehow sabotage the multilateral Copenhagen negotiations is, I think, overstated. More talk is always better, and good things happen when the world’s most high profile polluter signals its willingness to talk, and even initiate talks with countries whose development paths are at a critical stage.

    I have not been super hopeful about how things are going to turn out in the next few years. But things have changed quite a bit in the past year. The US appear to have their own climate bill brewing. Europe makes the right noises and has a head start,making the mistakes early. Unfortunately, Canada has given up the ghost thanks to our troglodyte oil man administration. Our main hope now is that the US passes a strong enough bill to affect Canada. Or there is an election leading to a change in administration and Mr Michael Ignatieff and the “liberals” are true to their word on a new, sustainable energy policy.

    Canada is now the worst laggard, having extremely high per capita emissions and policy to increase these emissions while actively sabotaging climate talks. We emit a full 2% of all global warming contributors while accounting for about 0.5% of the world’s population. It is understandable given our development path how we got there, but not trying to fix it is criminally negligent and morally bankrupt.

    Apparently, the Canadian people could care less, polls indicate that the business as usual administration is increasing its support among Canadians. What is the average Canadian’s responsibility if he/she knowingly supports policy that could lead to mass homelessness, flooding, starvation, wars, species extinction, etc?

    On Climate blog action day, I am sad to report that my adoptive country will do nothing but soldier on in its destructive behaviour. No point calling my local MP, she agrees with me!

    As the developed world vacillates, Indian villages go under

    Byoliveridley

    Sea gobbles up five villages in 15 years- Hindustan Times

    On Wednesday, a big tidal wave hit the coast in the Satabhaya area of Kendrapara district. It swept away homes and inundated farmland. But was no exception.

    Tidal waves like this one have been a regular phenomenon in the area. In the past 15 years, the sea has come inside the land by 2.5 kilometers. And as many as 600 families are leading a precarious existence in the Satabhaya and Kanhupur areas due to this phenomenon.

    Satabhaya, as the name suggests, once boasted of seven adjacent villages. Five of them have now been completely devoured by the sea. Thirteen families lost their homes to the surging waters on Wednesday. There was, fortunately, no loss of lives.

    Well, the consequences are set for the next 20 years, but still no action from the US on global warming which will determine how things are 50 years from now, I am not holding my breath.

    Arsenic in the News

    Byoliveridley

    Professor wins $1M for arsenic filter – Yahoo! News

    The National Academy of Engineering announced Thursday that the 2007 Grainger Challenge Prize for Sustainability would go to Abul Hussam, a chemistry professor at George Mason University in Fairfax. Hussam’s invention is already in use today, preventing serious health problems in residents of the professor’s native Bangladesh.

    This British Geological Survey website provides a good primer to the problem. Some key points:

    1. Arsenic is very toxic
    2. Arsenic is naturally occurring in the shallow groundwater aquifers of Bengal and Bangladesh at a toxic level
    3. The surface water is contaminated with bacteria and was responsible for high infant mortality, so aid agencies in the ’70s encouraged the use of tube wells and other groundwater pumps. While this contributed to a decline in infant mortality from gastrointestinal infections, it also dosed unsuspecting people with disease causing levels of arsenic
    4. The technology for removal of arsenic is very well known. But most solutions require electricity/periodic maintenance/technical skills and are thus not universal or sustainable.
    5. Simplicity is the key. You can’t tell the people to not drink the water, it is the only clean water available. You can’t install water treatment plants, there is no running water, you can’t rely on solutions that are centralized.

    So with all that in mind, here’s what Prof. Hussam did:

    The Gold Award-winning SONO filter is a point-of-use method for removing arsenic from drinking water.  A top bucket is filled with locally available coarse river sand and a composite iron matrix (CIM).  The sand filters coarse particles and imparts mechanical stability, while the CIM removes inorganic arsenic.  The water then flows into a second bucket where it again filters through coarse river sand, then wood charcoal to remove organics, and finally through fine river sand and wet brick chips to remove fine particles and stabilize water flow.  The SONO filter is now manufactured and used in Bangladesh. That’s great, and easy!

    That’s pretty much freshman chemistry right there, further proof that most innovation does not need new science, only people willing to spend some time on problems that don’t necessarily get looked at.
