There’s more energy in wasted food than there is in the Gulf of Mexico

Maggie Koerth-Baker at 8:42 PM Tuesday, Aug 3, 2010

Recently, while doing some research on the carbon footprint of food, I ran across some studies that reported Americans ate, on average, 3774 calories of food each day.

Something about that smelled funny to me.

Sure, Americans eat a lot. But 3774 calories a day? I have family members who subsist almost solely off fried meat and various sorts of potatoes and I’m not convinced that even they hit that number on a regular basis. When I took my questions to the researchers, I found out that my hunch was correct. Americans aren’t, technically, eating an average of 3774 calories per day. This figure is calculated by looking at food produced, divided by the number of Americans. It assumes we’re eating all that, but, in reality, according to environmental scientist Gidon Eshel we really only eat about 2800 calories per day. That whopping 3774 includes both what we eat—and what we waste.

And what we waste—not just at home, but from the farm field, to the grocery store, to our Tupperware containers full of moldy leftovers—is a big deal.

We use a lot of energy producing, transporting, processing, storing and cooking food we don’t eat. About 2150 trillion kilojoules worth a year, according to a recent study. That’s more kilojoules than the United States could produce in biofuels. And it’s more than we already produce in all the oil and gas extracted annually from the Gulf of Mexico.

Reducing that waste requires both changes in the way we eat at home, and systematic changes that address waste at every part of the food cycle. Right now, I’ve talked to a lot of researchers who can identify the problem, but don’t have a lot of suggestions for concrete solutions. I’m sure they’re out there, though, and I’ll report back as I track them down.

We Waste Millions O Megawatts On Night Lighting – I have been complaining about this for 25 years

Posted on by
Reply

Guess what it just gets worse every year. One year I put up the classic “night sky” compulation from the space station. It is horrid. And the excuses are myriad. One year I put up a picture of the Stratton Building in downtown Springfield. I swore 30 years ago I would live to see those lights out. Guess what? They are still on. The excuse: There are no individual shut off switches in the offices. Each floor is controlled my its main electrical panel,and the night janitors couldn’t see to do their jobs! Lighting on highways? What don’t cars have headlights? Street lightening? Gotta be able to see criminals. Put spotlights on the squad cars and get them off their dead asses. It just goes on and on and on and on. There is no off. So here is another story.

Federal Agency Headquarters Leave Lights On In DC

8:10 PM, Jan 25, 2011  |

WASHINGTON (WUSA) — Night after night, year after year, this nightside reporter observed lights left on in federal government buildings. So I decided to see just how much taxpayers were spending to keep empty buildings illuminated.

For several months, we kept track of the lights left on in a dozen federal buildings, including the Departments of Commerce, Agriculture, Transportation and Energy always checking after 10 p.m., each on at least six occasions.

“Turn the lights off. That’s what I do anyway. That’s how I save money,” said one visitor from North Dakota.

Just how much are the federal agencies electricity bills costing you, the taxpayer? First, using the Freedom of Information Act, we requested six months of utility bills for the headquarters buildings of more than a dozen agencies. Then, we asked taxpayers to estimate the price of one month in one building.

‘Whew. $3,000 a month?” one woman estimated.

“$5,000 a month?” guessed a young man from New Jersey.

“Monthly? $5-10,000,” said a man from Virginia.

The low end is about $200,000 a month. The high end more than a million. One month’s electricity bill at the Department of Labor topped a MILLION dollars. That was a bill paid in July of last year. The month before, the department paid a bill of nearly $700,000. And utility costs of that magnitude are not unusual.

“Whoooo. That’s too much!” exclaimed a taxpayer.

“Maybe the perception is, they want to tell the American people that we’re always on,” speculated another.

The Department of Health and Human Services paid a bill last August of $799,000 for a month of service.

“Oh my God. That is per month?” was one reaction.

The Department of Commerce paid a bill last June of $794,000.

“I used to work for the federal government. I know they waste tax dollars. Do it every day,” said a man in DC.

“Turning off the lights is about the simplest way that the government can save money. There is no excuse not to do this on a regular basis,” said Tom Schatz, President of Citizens Against Government Waste.

Most federal agencies purchase their electricity through PEPCO and Constellation New Energy of Baltimore. The buildings are large, and some appear to be making an effort to turn off their lights consistently, like the Department of Health and Human Services. The Department of Energy headquarters was so dark on one of our nighttime visits, we could barely see its sign.

Everyone has an excuse. For Cops it is they, “gotta be ready to roll”. For small town folks who leave their cars running at the curb, “it’ll just take a minute”. For bus drivers it is the mistaken notion that, “turning it off and on is harder on it then idling”. But it is all fuelish and wasteful.

Idle Reduction

Idling vehicles use billions of gallons of fuel each year and emit large quantities of air pollution and greenhouse gases. Idle reduction technologies and practices are an important way to cut petroleum consumption and emissions.

Idle Reduction Basics

Idling Facts

  • Medium-duty trucks use about 2.5 billion gallons of fuel to idle each year, or 6.7% of the total fuel they consume.
  • More than 650,000 long-haul heavy-duty trucks idle overnight for required rest stops at least some fraction of the time, using more than 685 million gallons of fuel per year.

Idle reduction describes technologies and practices that reduce the amount of time drivers idle their engines. Reducing idling time has many benefits, including reductions in fuel costs, emissions, and noise.

Drivers idle for a variety of reasons, such as keeping vehicles warm, operating radios, or powering equipment. Each year, U.S. passenger cars, light trucks, medium-duty trucks, and heavy-duty vehicles consume more than 6 billion gallons of diesel fuel and gasoline—without even moving. Roughly half of that fuel is wasted by passenger vehicles.

Idling can be reduced without compromising driver comfort or vehicle equipment operations. Learn about:

Gas Flares At Garbage Dumps – Humans just throw resources away

Posted on by

In 1000s of landfills across the nation natural gas (primarily methane) is being allowed to drift into the atmosphere or worse yet “flared”. They should be at least using this to generate electricity. Like this landfill in Brevard County.

http://www.brevardcounty.us/swr/landfilltour.cfm

Your Guide to the Central Disposal Facility

click for larger image

The Central Disposal Facility (CDF) is located on Adamson Road in Cocoa. The property was first used for solid waste disposal in the 1960’s. Since then the County has continued to make improvements operationally and environmentally. For example, the 192-acre permitted landfill area is lined by a clay slurry wall, groundwater monitoring wells have been installed, and a methane gas collection and flare system is in place.

The site originally consisted of 285 acres. CDF now totals 957 acres. Portions of the landfill have been closed by capping it with a liner, two feet of cover dirt, and sod. It is estimated Brevard County will have enough landfill capacity to handle the disposal needs for the county until 2014.

In addition to the landfill area itself, there are many other areas within the landfill which emphasize waste reduction and environmental protection.

Yard waste is banned from Florida landfills but is used for daily cover material in the landfill after it’s mulched.

Tens of thousands of pounds of mulch is sent to a facility in Auburndale to be converted to Green Energy.

The mulch is available FREE to all Brevard County residents,
call (321) 633-1888 for more information.

 Mulching

Landfill Gas Conversion to Green Energy
click for larger image 		The gas produced by the Landfill (methane) is extracted through a vacuum system run by LES (Brevard Energy LLC) which in turn is connected to a power grid at the FP&L Facility
(Oleander Plant) and converted to Green Energy.
Anaerobic bacteria break down the garbage in the landfill which produces methane gas. These Flares were burning off the methane to reduce build-up in the landfill.

Now that the Landfill Gas Plant is up and running the Flare Station will be utilized only when necessary.

Wasted Energy – Very cool blog

I started a meditation on wasted energy last Friday by looking at all the energy we waste by “flaring” natural gas at drilling rigs. We burn more than we use. Then I got distracted by the Corps of Engineers opening the Morganza  Spillway which is a huge environmental deal. So I come back to the meditation today. I googled up the issue and this site popped up. It’s a pretty cool blog. They haven’t posted since April so I am hoping I am not hyping a dead blog.

The Palest Green

Posted by wastedenergy on April 6, 2011

Now that enough time has passed to witness what is really happening in Fukushima, I am ready to pass judgment. I notice a lot of other commentators offered their two cents up immediately, as if they could tell the full scale of the disaster from the first few hours. Not me, though. I knew something strange was afoot the instant it happened, but it’s important to keep in mind that one must always do the necessary homework before making ultimate determinations of value. Now that time has come.

The most common argument I see supposed “environmentalists” making in favor of “nuclear power” (which is a misnomer since it is actually a drain on energy over the long run) is that it is “better than coal.” “It’s carbon neutral,” they say, as if to suggest that were the only criterion that mattered, and also as if to ignore the full energy-consumptive effects of the nuclear fuel cycle from mining to ultimate disposal (it’s supposed to get disposed ultimately, right?). But the path to “clean” nuclear energy is laid with many other booby traps, and it takes an eye open to truth and closed to propaganda to catch them all.

In nature, the color yellow often means “Don’t touch me, I will hurt you.”

As I see things today, the quest for nuclear power, hailed as tomorrow’s energy source by those so obsessed with technocracy that they blind themselves to the big picture, represents better than almost any other story our civilization’s descent into madness. We have become truly power-obsessed, seeking cheap thrills today and tossing tomorrow to the winds. Let our children handle the nuclear waste, we keep saying. Well, the children have arrived, and they are ready to take the reins of power now, and we still aren’t any closer to figuring out what to do with this stuff, which keeps piling up in spent fuel pools vulnerable to release into the environment from earthquakes, volcanoes, meteor strikes, acts of sabotage, and all the other hazards that are a natural part of life on Planet Earth. So what makes today’s nuclear scientists so certain that tomorrow we will finally come up with the magic solution that will allow us to seal this stuff forever behind closed doors, especially if we continue to create even more? It’s time to stop kicking the can ever further down the road and face up to the reality we’ve created for ourselves.

Nuclear fission and radiation are natural parts of our existence. Decaying radioactive isotopes are what power the Earth’s geothermal heat, much like nuclear fusion powers radiation from the Sun. We tell ourselves there cannot be a hazard here since it is always around in one form or another. But we overdo it sometimes, and just as with oil depletion, we trick ourselves into thinking what we are doing is perfectly natural by suggesting “there’s always going to be some, so it can’t be so bad.” That is, once again, the continuum fallacy. We presume that just because we cannot draw a clear line between one phenomenon and its much larger version, that there must be no difference at all. The disaster at Fukushima, which has caused radiation levels to spike to millions of times background levels, has proven conclusively that there are real clear and ever-present dangers associated with even the most carefully operated nuclear power reactors, and the silver lining in the event is that it has brought these as well as the dangers associated with the back end of the nuclear cycle into the forefront of discussion and back into clear view. Such a perspective is necessary if we are to take an objective look at the advantages and drawbacks of our different energy options, something many players with vested political and economic interests are not particularly keen on seeing.

Tear Down This Wall Lt. General Robert Van Antwerp

We need to return to a more natural way to handle our waterways in the Mississippi Watershed. There is farmland that floods. Let it. These are bottom lands that should only be farmed at the farmers expense. There are towns that need to be moved. We can not control the watershed so we should stop trying.

http://news.yahoo.com/s/ap/us_mississippi_river_flooding

By MICHAEL KUNZELMAN, Associated Press – 1 hr 6 mins ago

KROTZ SPRINGS, La. – Renee Ledoux cried when the National Guard and sheriff’s deputies showed up at her front door and warned her she needed to get out to avoid water gushing from the Mississippi River after a floodgate was opened for the first time in four decades.

But by the 5 p.m. deadline Sunday, the 44-year-old Ledoux and her boyfriend Billy Hanchett decided to ride it out one more night on air mattresses inside the empty home in Krotz Springs. They have a camper they plan to stay in on a friend’s property outside the flood zone.

“We really don’t want to go,” Hanchett said. Ledoux added that she felt blessed that they had the camper because a lot of others have nowhere to go except shelters.

Meanwhile, President Barack Obama planned to fly to Memphis, Tenn., on Monday to meet with families affected when the river flooded there as well as local officials, first responders and volunteers.

Deputies all over Louisiana Cajun country were warning residents to head for higher ground and most heeded it, even in places where there hasn’t been so much as a trickle, hopeful that the flooding engineered to protect heavily populated New Orleans and Baton Rouge would be merciful to their way of life.

Days ago, many of the towns known for their Cajun culture bustled with activity as people filled sandbags and cleared out belongings. By Sunday, some areas were virtually empty as the water from the Mississippi River, swollen by snowmelt and heavy rains, slowly rolled across the Atchafalaya River basin. It first started to come, in small amounts, into people’s yards in Melville on Sunday. But it still had yet to move farther downstream.

The floodwaters could reach depths of 20 feet in the coming weeks, though levels were nowhere close to that yet in the towns about 50 miles west of Baton Rouge.

Elsewhere, in an effort to keep a major shipping connection between the Gulf of Mexico and the Mississippi River open, the U.S. Army Corps of Engineers moved in a fifth dredge to dig sediment out of the Southwest Pass. A high river brings a huge amount of sediment and the dredges were being used to keep the 45-foot channel needed for deep-draft shipping.

Over the weekend, the Port of New Orleans said it had been told by the Coast Guard that shipping probably would continue largely unhindered on the lower Mississippi.

And that is what they want to protect. Baton Rouge and New Orleans are irrelevant. It’s the refineries, the petro-chemical plants and shipping that really matter. Please read the rest of the article. It is a pretty good “on the ground” coverage. They don’t come to the same conclusions that I do but then that is why I am me. More tomorrow.

We Needlessly Burn 150 Billion Cubic Meters Of Natural Gas Every Year

That’s right. On almost every large drilling rig producing large amounts of oil there is a continuously burning flare of natural gas. This is a hold over from the days when natural gas was seen as a nuisance rather than a fuel source. BUT that was over 100 years ago. How long does it take to change the rules.

Why is methane flaring bad for you?
According to the World Bank, flares waste 150,000,000,000 cubic meters of natural gas (methane) each year. This is the equivalent to the energy in 60,000,000,000 gallons of gasoline (estimate).

Green GPS calculates most fuel-efficient route

by Kim Gudeman, CSL Green GPS technology May 3, 2011 – 3:14pm

A new software interface reduces energy consumption in transportation systems.

Green GPS, developed by computer scientists at the University of Illinois at Urbana-Champaign, works like general GPS navigation, except that in addition to calculating the shortest and fastest routes, it also projects the most fuel-efficient route.

“Currently at least 30 percent of total energy in the United States is spent on cars,” said Principal Investigator Tarek Abdelzaher, associate professor of computer science and researcher in the Coordinated Science Laboratory. “By saving even 5 percent of that cost, we can save the same amount of total energy spent on the nation’s entire information technology infrastructure.”

The technology runs on cell phones, which links to a car’s computer using an inexpensive, off-the-shelf wireless adapter that works in all cars manufactured since 1996. The car’s onboard diagnostics system uploads information about engine performance and fuel efficiency to the phone, which uses the data to compute the greenest route.

A grant through the National Science Foundation to Abdelzaher and Robin Kravets, also a member of Illinois’ computer science faculty, is funding a large-scale deployment of the service via the University of Illinois’ car fleet. The Office of Naval Research is funding research related to the technology’s networking component. Researchers — including Dr. Omid Fatemieh, graduate student Hossein Ahmadi and research associate Hongyan Wang — also are collaborating with IBM through its “Smarter Planet” initiative.

Pete Varney, who oversees some of the approximately 500 vehicles used by the Urbana-Champaign campus, hopes research will help maximize fuel efficiency for the fleet. The units will be installed on up to 200 vehicles, including full-size vans that could be carrying 1,000 pounds or more in tools and equipment.

“The less money we can spend on fuel, the more money we can direct toward maintaining other things on campus,” said Varney, director of Transportation & Automotive Services.

In addition, researchers are developing a social network of drivers who can share information about their cars. In the future,

Evolutionary lessons for wind farm efficiency

Wednesday, 4 May 2011

Evolution is providing the inspiration for University of Adelaide computer science research to find the best placement of turbines to increase wind farm productivity.

Senior Lecturer Dr Frank Neumann, from the School of Computer Science, is using a “selection of the fittest” step-by-step approach called “evolutionary algorithms” to optimise wind turbine placement. This takes into account wake effects, the minimum amount of land needed, wind factors and the complex aerodynamics of wind turbines.

“Renewable energy is playing an increasing role in the supply of energy worldwide and will help mitigate climate change,” says Dr Neumann. “To further increase the productivity of wind farms, we need to exploit methods that help to optimise their performance.”

Dr Neumann says the question of exactly where wind turbines should be placed to gain maximum efficiency is highly complex. “An evolutionary algorithm is a mathematical process where potential solutions keep being improved a step at a time until the optimum is reached,” he says.

“You can think of it like parents producing a number of offspring, each with differing characteristics,” he says. “As with evolution, each population or `set of solutions’ from a new generation should get better. These solutions can be evaluated in parallel to speed up the computation.”

Other biology-inspired algorithms to solve complex problems are based on ant colonies.

“Ant colony optimisation” uses the principle of ants finding the shortest way to a source of food from their nest.

“You can observe them in nature, they do it very efficiently communicating between each other using pheromone trails,” says Dr Neumann. “After a certain amount of time, they will have found the best route to the food – problem solved. We can also solve human problems using the same principles through computer algorithms.”

Dr Neumann has come to the University of Adelaide this year from Germany where he worked at the Max Planck Institute. He is working on wind turbine placement optimisation in collaboration with researchers at the Massachusetts Institute of Technology.

“Current approaches to solving this placement optimisation can only deal with a small number of turbines,” Dr Neumann says. “We have demonstrated an accurate and efficient algorithm for as many as 1000 turbines.”

The researchers are now looking to fine-tune the algorithms even further using different models of wake effect and complex aerodynamic factors.
