"hydrogen-fuel-cell cousins are, in many ways, simply flashy distractions produced by automakers who should be taking stronger immediate action to reduce the greenhouse-gas emissions of their cars. "
Nobody has made this point more clearly than Joseph Romm does in Hell and High Water. Romm is an MIT-trained physicist who managed energy-efficiency programs in the U.S.
Department of Energy during President Clinton's administration and now runs a consultancy called the Center for Energy and Climate Solutions. His book provides an accurate summary of what is known about global warming and climate change, a sensible agenda for technology and policy, and a primer on how political disinformation has undermined climate science. In his view, the rhetoric of "technology breakthroughs"--including the emphasis by President Bush and some in the auto industry on a future hydrogen economy--provides little more than official cover for near-term inaction.http://www.technologyreview.com/Energy/18301/
"This (warming) has already had a huge impact on the state of California," Patzert said. "It's changed the way we do agriculture, it's changed the energy and water demands, it's changed the number of days we've had frost or extreme heat."

According to www.FuelEconomy.gov:
"Biodiesel is a form of diesel fuel manufactured from waste oils, animal fats, or recycled restaurant greases. It is safe, biodegradable and produces less air pollutants than petroleum based diesel." And, the best part is, most diesel fuel vehicles are currently able to run on biodiesel fuels.
- Is a completely renewable source of fuel.
- Can be produced from products (restaurant greases) that would otherwise be thrown away.
- Emits substantially less hydrocarbons, carbon monoxide, sulfur oxides and sulfate.
- Biodegradable and less toxic to handle when compared to gasoline.Cons:
- Currently, if you try and use biodiesel fuel in your diesel vehicle, it may void your car's warranty.
- Unless you're getting waste products from restaurants for free and then converting it to biodiesel yourself, it's going to cost you more than gasoline.
- Emissions include a slight increase in nitrous oxide, which is commonly referred to as "laughing gas."
- Tends to not perform well in cold temperatures.
To add to the cons: - Demolition of the remains of the world's rainforests to grow the stuff, should it be adapted on a wide scale. Humans already appropriate something like 50% of the entire biological productivity of the planet for food, wood and fuel; biofuels on any meaningful scale would push this towards 100%.

Automakers said they could make half of their cars and trucks capable of running on alternative fuels by 2012 if there is enough availability and distribution of E85, an ethanol blend of 85 percent ethanol and 15 percent gasoline.
"This makes a big difference," Wagoner said. "There's nothing that can be done that can reduce the curb of growth of imported oil, and actually turn it down, like using E85." ... gets you this:
The government issues a report this week that is likely to show one of the most dramatic shifts in U.S. crop acreage in memory.
... growers are going to plant more acres to corn this year and significantly fewer acres to cotton, soybeans, wheat and other crops. Environmental groups said the focus on ethanol blends would undermine attempts to push automakers to make more fuel efficient cars.
Yeah, but where's the big-money constituency for that? From Cause and effect (Thanks GRIST! ;-)

Kent County utility operator Nathan Dannenberg, who runs the sewage treatment system for Sand Lake, discovered the leak in the 8-foot-deep lagoon on Friday while taking samples. It wasn't clear when or why the leak occurred.
This is of some concern to locals, as their water supply is taken from wells that are downstream of the now mysteriously vanished sewage.
'We don't smell anything, and we don't see anything,' said Nathan Danenberg, the man in charge of sewage treatment for the village, told The Grand Rapids Press. "I don't know if maybe there are old mines in the area ... It's an odd case. A sinkhole gobbled up all the water and we don't know where it went... It seems to have just gone down into the earth."
Being green with electronics doesn't mean living in a teepee listening to truckers squalk on the old short-wave. Greening your electronics is a matter of knowing what tech to get, how to use it best, and what to do with it when its useful life is done.
For example, electronics like your TV consume power whether they're turned on or not, meaning that even though you may not be watching TV, your TV's still eating up a lot of power. The same is true of AC adapters. A good way to remedy this problem is by plugging these items into a power strip and flipping the switch there whenever you're not using those devices.

I came across the important thread every critic and proponent should read... "great post engineer-poet AND a timely focus - concerning an energy carrier 'nicknamed' an energy source by to many. And on top of it all - it is the most minuscule particle in the universe - the hardest little thing to contain that is ...
Engineer-Poet - I had similar goals for "Sustainability", except that I was trying to pull old interest groups away from the current dysfunctional system rather than create new ones.
Another possibility. The scientists themselves are human and are themselves in denial and are unable to admit in print the fix we are in. It is kind of like going to a doctor and having him tell you that you have 4-6 months to live - how easy would it be to go out and tell others this grim news?
Right now, it is a crisis only in the minds of the doomers.
Engineer-Poet - True. However, a failure to act to head off a crisis practically guarantees we'll sleepwalk into one. In that sense, the doomers are not wrong so much as premature.
Some of this obstruction is more or less direct set to deliver product in the 2007 timeframe and also suitable for PHEV modification, and replacing it with a program of dubious feasibility and a very long time horizon), but some of it is more subtle, taking the form of misdirection.
This misdirection is evident in the shameless promotion of unready and perhaps impossible fixes, such as:
- Cellulosic ethanol.
- Oil from ANWR (at best, a fraction of what we could save with better CAFE or just plain price-driven demand destruction), and last but not least,
In this climate of disinformation comes a paper from Purdue, titled Sustainable fuel for the transportation sector. The premise is rather simple: US production of biomass contains sufficient carbon to replace all our transportation fuel...
In the H2CAR paper, figures such as 239 billion kg/year of hydrogen from 58,000 km2 of solar PV panels are tossed off rather casually.... cost would be closer to $40 trillion. Clearly we're not going to do this. Another example of the disconnect between the researchers and reality is their proposed quantity and method of hydrogen production. Their most optimistic (smallest) quantity of hydrogen required is 239 billion kg/year, which they propose to produce from renewable electricity via electrolysis. The quantity of electricity required (at 100% efficiency, no less) is a staggering 9810 billion kWh/year2; this is nearly 2.5 times current annual US electric production.
Maybe, just maybe, this will help slay one more of the non-options so we can get on with the things that might actually work.
The impact of today's energy crunch on the poor is plain in rich nations such as America: Expensive gasoline and soaring heating bills make a hard life harder. In impoverished countries such as Guinea, where per capita income is just $370 a year and surging gasoline prices have helped spark bloody riots, the energy shock has become a matter of life and death. The energy shock's impact on the world's poor is uneven. An estimated 1.6 billion people, most of them rural dwellers, lack access to electricity and 2.4 billion still cook over fires of wood, charcoal or dung.
The new fuel shortages make life tough at Donka Hospital, where Mr. Diallo, the aspiring doctor, just started making his rounds as a student intern. The hospital has priority on the city's electricity grid, but blackouts are frequent. Patients bring their own flashlights. The main backup generator burns through 40 liters of fuel an hour, at a cost of about $40 an hour at current rates. So, that generator sits idle.
Dr. Baldé and his team of 14 doctors at the infant-care ward cope as they can. If a blackout lasts longer than an hour or so, temperatures inside the incubators start to fall. Nurses pick babies out and bury them in blankets on their mothers' warm bellies.
"There were too many stoppages in his therapy" because of the blackouts, Dr. Joumah says, wincing and shaking his head. The baby died after about a week. He had other complications, but Dr. Joumah blames the power cuts. "It happens all the time," he says.

The future is not now for biomass ethanol industry. The logistics of collecting and storing a million tons of corn stubble each year for an ethanol refinery are mind-numbing.
"It would take 67,000 semitrailer loads to haul the baled stubble out of the field. That's 187 truckloads a day, or one every eight minutes. To complicate matters, the need for trucks, machinery and manpower would come during harvest, already the busiest time of the year on the farm. And that's where a massive federal initiative into cellulosic ethanol may find its biggest bottleneck - on the farm."
According to the article, a million tons would produce 80 million gallons of ethanol. This would be enough on a gross basis to displace 0.04% of our gasoline usage. So, if all the inputs were free, all we would need is 2,500 of these facilities, and we will have met all U.S. gasoline needs (but not diesel, fuel oil, or jet fuel). Ah, but we forgot about energy inputs. How many gallons of fossil fuels did it take to run all of those semi-trailer trucks to take the stubble to the plant? How much natural gas was required to distill off the ethanol? But we are told that these are "small problems." Easily resolved.
More efficient production means less energy used per unit produced. It means less material resources are used per unit produced, and materials (and energy, for that matter) are used or reused more efficiently. Aside from the obvious savings on production costs, this more efficient use means not only less energy and raw materials consumed, but also less material emitted to air and water, and less solid/hazardous waste generated.
EPA has begun to look very closely at lean as an area in which environmental and business practitioners can work together. In January 2006, EPA developed and published "The Lean and Environment Toolkit." The Toolkit incorporates tools already developed and used by our partners, as well as new ideas that arose during our collaboration. Lean practitioners will find these tools to be very familiar; for the most part, they're traditional lean tools with slight adaptations to account for a slightly different perspective. EPA's lean website provides a link to make such suggestions. We really want to hear from you. Please contact us at www.epa.gov/lean
Environmental Waste: An Overlooked Savings Opportunity - If cost-reduction opportunities concerning environmental wastes are being overlooked, then the true costs of production are not really being accounted for.... it is likely a simple question of priorities.
Test kits are available from local health departments all across the state. The cost generally ranges from $5 to $15, including postage and lab fees. Kits are also available from some home improvement centers and hardware stores, but not all retail kits include postage and analysis, so citizens are urged to carefully read the packaging before making their purchase.

The facility is able to generate biogas from manure and other agricultural waste streams, condition the biogas to natural gas standards and distribute it via a commercial pipeline. Microgy's has branded, the renewable, pipeline-quality biomethane product as 'Renewable Natural Gas'.
At full build out, Huckabay Ridge may be the largest biogas production facility in the world, with annual output of approximately 650,000 MMbtus of RNG per year - the equivalent of over 4.6 million gallons (17.4 million liters) of heating oil.
Large volumes of plastic waste generated aboard military, merchant and cruise ships must be stored onboard, often for prolonged periods, until they make port. In the future, the new type of environmentally friendly plastic may make it safe and practical to toss plastic waste overboard, freeing-up valuable storage space.
The biodegradable plastics could replace conventional plastics that are used to make stretch wrap for large cargo items, food containers, eating utensils and other plastics used at sea, the researchers say. The biodegradable plastic has not yet been tested in freshwater. The development was described today at the 233rd national meeting of the American Chemical Society.
"There are many groups working on biodegradable plastics, but we're one of a few working on plastics that degrade in seawater," says study leader Robson F. Storey, Ph.D., a professor of Polymer Science and Engineering at USM, located in Hattiesburg, Miss. "We're moving toward making plastics more sustainable, especially those that are used at sea."
"As major contributors to the global economy, the U.S. and India are important to the health of the global environment," said EPA Administrator Stephen L. Johnson. "As we are seeing in the U.S., environmental progress and economic growth can, in fact, go hand-in-hand. We welcome this opportunity to share our experiences and lessons learned in order to accelerate the pace of environmental protection in both our nations."
Johnson will conclude his visit to India by discussing EPA's methane gas recovery and mercury programs with the Federation of Indian Chambers of Commerce and Industry, and he will also meet with government officials from the Planning Commission and Ministry of Science and Technology on avenues of collaboration to strengthen environmental protection.

It is a commonplace that climate change will mean different locations for climate zone, and maybe some new zones altogether. No news in that, but a new study attempting to provide some detail is getting attention. It's from researchers at the University of Wisconsin and the U. of Wyoming. Not only will some new tropical zones appear, but some kinds of climate may disappear from the planet, the study concludes. Dramatic shifts are due for some of the globe's most populated areas, too, including Southeast Asia, parts of the US, much of Africa, and the Andes. The shifted climate will bring novel conditions to about 40 percent of the planet, it says here. Pic hi res here.

The "bio fuel cell" uses an anode coated with oxygen-tolerant hydrogenasesenzymes from a naturally occurring bacterium that oxidize hydrogen in its metabolismcoupled with a cathode modified with the fungal oxygen reductase, laccase. Laccase catalyses the reduction of oxygen to water.
The enzyme-coated electrodes are placed inside a container of ordinary air with 3% added hydrogen.
Prototype versions of the cell produced enough electricity to power a wristwatch and other electronic devices. Armstrong foresees advanced versions of the device as potential power sources for an array of other electronic products that only require low amounts of power.
The technology is immensely developable. We are at the tip of a large iceberg, with important consequences for the future, but there is still much to do before this generation of enzyme-based fuel cells becomes commercially viable.
The Chinese companies interested in investing in Brazilian ethanol mills could be Jilin Fuel Ethanol, Henan Tianguan, Anhui Fengyuan Bio-Chemical and Heilongjiang China Resources Jinyu, which together produce 1 billion liters (264 million gallons US) of ethanol per year, said the report.
China is the world's third largest ethanol producer behind the US and Brazil, but the country has limited land and water for agricultural expansion. In December, the Chinese government directed ethanol producers to concentrate on using non-food crops as feedstocks due to concerns about food prices. (Earlier post.) Source greencarcongress.com

According to the U.S Environmental Protection Agency, a single household open burning unsorted trash can produce as much of some cancer causing emissions as a 200-ton-per-day municipal waste incinerator with high efficiency emission control technology.
"Burning any material, whether plastic, paper or wood, produces a variety of hazardous and toxic air pollutants, including carcinogens such as arsenic, benzene and formaldehyde," said Neal Baudhuin, Department of Natural Resources air management supervisor at Rhinelander. "Looking for alternatives to burning is one thing everyone can do to help our environment," he added.
Burning poses fire danger - Debris burning is also the number one cause of wildfires in Wisconsin.
These fires often threaten the safety of citizens and fire fighters, burn structures, and damage natural resources. Because of their danger, debris burns are regulated by state code. Requirements include not burning until after 6 p.m. nor on Sundays, holidays and during high winds when the ground is not snow covered.
Permits for burning outside of city limits may be obtained at DNR service centers local ranger stations or from volunteer emergency fire wardens in the community. Permits help inform local citizens of the correct method to burn allowable materials and alerts fire fighters to locations of where to expect smoke.
Even though a person has a permit, if a fire escapes from control or the person fails to extinguish the fire, he or she can be held responsible for all costs of suppression and civil damages. Anyone burning without a permit may be issued a citation.
In addition, burning the following materials is prohibited under any conditions:
- wet, combustible rubbish;
- oily substances, such as oily or greasy rags and oil filters;
- asphalt products such as shingles or tar paper;
- plastics of any kind, including plastic bottles and plastic bags;
- rubber products, including tires and hoses;
- treated, stained or painted wood; and
- upholstered furniture, bedding, carpeting, etc.
- recyclable paper or cardboard; and
Homeowners may also burn small quantities of nonrecyclable paper and unpainted, untreated wood. State and local laws require recycling of plastic containers, corrugated cardboard, newspaper, magazines and office paper. Penalties can be assessed to individuals and businesses for the improper disposal of recyclables.
However, if people do choose to burn, DNR air quality specialists say they should be courteous to neighbors and be aware of the effect the smoke and air pollution has on people and the environment downwind. They recommend people look into alternatives to getting rid of burnable waste.
"Property owners may want to donate items like furniture, appliances and other usable household items to local thrift stores, charities or schools as a first option rather than burning or landfilling them," said Bob Germer, a DNR recycling specialist.
Brush, leaves and plant clippings could be composted. Backyard composting information is available at local DNR Service Centers.
Outdoor enthusiasts may want to use renewable paper products for meal preparation rather than more costly, hard-to-manage plastic and foam utensils. Burning a paper plate in a campfire creates less of an environmental and human health impact than the black noxious smoke of a foam plate. Wash and reuse the plastic utensils.
Businesses , commercial enterprises, and industries may not use burn barrels or openly burn wastes and may not be granted burning permits by municipalities. Businesses may obtain a permit to burn small brush piles that are the result of clearing business property on a case-by-case basis.
The Department of Natural Resources encourages all persons to consider alternatives to open burning such as reducing the amount of waste produced, reuse of items, recycling, chipping and composting yard and brush and landfilling.

In Lyon, according to deputy mayor Touraine, the city's 3,000 rental bikes have logged about 10 million miles since the program started in May 2005, saving an estimated 3,000 tons of carbon dioxide from being spewed into the air. Overall, vehicle traffic in the city is down 4 percent, he said, and bicycle use has tripled, not just on account of Cyclocity, but also because the program has prompted a boom in private bicycle use and sales.
NOT A NEW IDEA - The Cyclocity concept evolved from utopian "bike-sharing" ideas that were tried in Europe in the 1960s and '70s, usually modeled on Amsterdam's famous "white bicycle" plan, in which idealistic hippies repaired scores of bicycles, painted them white, and left them on the streets for anyone to use for free. But in the end, the bikes were stolen and became too beat-up to ride.

The cocktail of hazardous substances that we rely on to make our bathrooms sparkle or our floors shine is truly obscene.
According to the U.S. Environmental Protection Agency, the air inside the typical home is on average 2-5 times more polluted than the air just outsideand in extreme cases 100 times more contaminatedlargely because of household cleaners and pesticides.
So, Worldwatch is pushing a different approach to Spring cleaning. You guessed it: green cleaning products.
Keeping our homes clean and avoiding toxic cleaners don't have to be mutually exclusive, says Worldwatch.
Green cleaners can also be made from a range of safer substances we might already have around the house.
You won't just be making your house healthier.
How about healthier streams? In a 2002 U.S. Geological Survey study of contaminants in U.S. stream water, 69 percent of streams sampled contained persistent detergent metabolites, and 66 percent contained disinfectants.
You knew that dishwashing detergents often contain phosphates that pollute the groundwater, right?
Didja know that eleven U.S. states have banned phosphate from detergents sold within their borders?
