Wasted Food Is Wasted Energy – And we waste alot

Remember when your mom used to say, “Clean your plate. There are children in the world who are starving.”? Well now it is save the world kind of stuff. Wasting food wastes huge amounts of energy. This brief article below sums it up nicely. Please click on the authors name to see more of this authors work.

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.

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.

Wind Power Evolves – Using alternative energy makes you smarter

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.

Incredibly, impossibly beautiful time lapse video

I’ve been posting a lot of time lapse videos lately, and they’re so amazing I keep thinking they can’t possibly get any more beautiful.

I keep thinking wrong.

“El Cielo de Canarias” (Canary Sky) is simply, unbelievably breathtaking.

Wow. I mean, wow. Daniel López is a gifted photographer. While looking at his photographs, my jaw literally dropped. They are that extraordinary.

Many years ago I visited La Palma, one of the Canary Islands, for a meeting. In the distance we could sometimes see the very top of Mt. Teide, seen in this video, poking over the clouds. It was so unearthly and captivating, and López has captured that feeling here. This video has everything! The fluid motion of the clouds, a double rainbow (yes, yes, I know), a corona around the Sun (not the Sun’s atmosphere, but a lovely optical effect from water droplets in the clouds), standing-wave lenticular clouds, even a Green Flash! Watch the stars as they wheel across the view; can you spot the Pleiades, the Andromeda Galaxy?

As many of these videos as I have seen, I’m still looking forward to more from Sr. López. This one is absolutely stunning.

Tip o’ the lens cap to Felipe Gallego.

Could not get the video to go up but go to the website and see. More tomorrow.

Springfield, Illinois – Lawrence Education Center will distribute trees to students in order to celebrate Earth Day. During the event, students will be educated about trees and how they help the environment. The trees will be given to students along with a postcard to give back to the Lawrence Education Center that will mark the location of where the trees are planted. The school will create a map that will include the location of the trees that were planted. This event is made possible from the Illinois Department of Transportation who is teaming up with a national initiative called Living Land and Waters.

Students who want a tree to plant can come to the library when they are finished with classes for the day on the following dates:

Thursday, April 14, 2011 Room 109 , Lawrence Memorial Library, Michele Romence
Friday, April 15, 2011 Room 109 , Lawrence Memorial Library, Michele Romence

CHICAGO — Gov. Pat Quinn wants to see electric cars in the state fleet.

Quinn talked about transportation at an Earth Day summit in Chicago on Tuesday.

In addition to electric cars, Quinn says he’d also like to see a universal card system for public transportation and Wi-Fi on the commuter rail system Metra. He was the opening speaker at a seminar that featured state and local transportation agencies.

Quinn says Illinois is working to encourage electric vehicle manufacturers to bid for state vehicle business. He says one place they’d fit in are as vehicles on the state’s university campuses.

Quinn says the rising cost of gas makes electric cars even more appealing. He says a proliferation of charging stations is the key to successfully deploying electric vehicles.

Solar Plane Will Make First European Flight – Actually land at a real airport

While the Solar Impulse has flown around the world it has never landed at a major airport or filed a real flight plan. This is too cool for words. I know this is not an Earth Day thing but it should be.

Solar Impulse on stand-by from Monday

author: Bernard Schopfer

2011-04-28

In these last few weeks the entire Solar Impulse team has been busy doing “test flights” in the Payerne area, to test the satellite communication systems developed by Swisscom, and also the air traffic integration procedures. The support received from the aviation authorities in the overflight and destination countries has been extremely positive and constructive.

For the European solar flight campaign the Solar Impulse team, sponsored by the European Commission, has chosen Brussels as the 1st international destination. The airplane will be shown in the European capital from 23 to 29 May 2011 and will then attempt to reach Paris-Le Bourget, where it is expected as a “Special Guest” at the 49th International Paris Air Show.

“These tests have been extremely successful”, says an elated Bertrand Piccard. “Now, here we are in the definitive phase: it’s no longer a question of tests, but the real thing. And the next flights will not be made in the “familiar cocoon” of Payerne aerodrome, but in the whole of Europe…” Rather like a sailing ship that has undergone coastal trials, and is now set to cross its first ocean!

“We will be in stand-by mode from Monday”, explains André Borschberg, who will pilot the HB-SIA between Payerne and Brussels. “And we definitely mean to take the first opportunity that comes along, since we can never be sure of the weather conditions and whether they will allow us to do this flight on a particular date. With Solar Impulse we are confined to what we can do with the technology at the present time, and safety is our number one priority.”

The Springfield Earth Awareness Fair Is On May 7th

This event used to be the weekend after Earth Day and was Springfield’s celebration of it. Several years ago the organizers decided to break that pattern and hold it at different venues and at different times. I am “jake” with that. As the original organizer of the first day said, “Everyday should be an Earth Day”. This year it is at our cool new park with its geothermal heating and cooling, AND its wind turbine. YAH!

18TH ANNUAL EARTH AWARENESS FAIR

The 18th Annual Earth Awareness Fair will be held Saturday, April 24 from 10:00 a.m. to 2:00 p.m. at the Old State Capitol. “Springfield’s annual Earth Awareness Fair is the oldest continuous Earth Day celebration in Illinois and we are proud to host this all-ages event,” said Mayor Davlin.

Information on eco-friendly choices such as recycling, energy efficiency, native plants/ habitat and water conservation will be available. Exhibits, giveaways, games and crafts will be offered, all with an environmental message. Live music will be provided by local musicians Tom Irwin and Thornhill. A bicycle rally will be held with bicyclists gathering at the Old State Capitol at 12:00 for a ride around the downtown area to raise awareness of alternative forms of transportation.
Rain barrels will again be available for sale at the Fair.

Using a rain barrel is an excellent way to lessen the demand on our drinking water systems and reduce energy consumption by not having to purify ground water for residential irrigation purposes. Area homeowners can save money while helping the environment and reducing storm water run-off by capturing water in rain barrels.

Admission to the Earth Awareness Fair is free. It will be held rain, or shine. Join us for the 40th anniversary of Earth Day!

Earth Day 2011 – Here is the first post

I am probably going to post Earth Day stuff for the next week. I see it as a way to hook up with old friends like today’s Shawna Coronado or new friends unknown.

Green Tip #6-Earth Day Is Every Day, Just Ask My Plastic Bag Thong Underwear Oak Tree Art

Plastic Bag Thong.jpg

Earth Day should be every day. Just ask my oak tree which currently has a plastic bag hanging in it 28 feet up that remarkably resembles a pair of thong underwear. No kidding.

Why are we celebrating the earth just one day of the year? It has given us everything we have, wear, and eat – yep, even thong underwear. Without the earth humanity would not exist. With the earth we exist. Pure and simple.

Stop messing around people – pick up your trash so it does not get caught in a tree for some bird to get tangled in. Recycle your glass, plastic, and paper, so we save our natural resources. Make a difference every day, not just on Earth Day – it is the right thing to do.

Now. Who’s going to climb 28 feet up to help me get the thong out of the tree? Volunteers?

Mercury Is Good For Us – Just like the other coal pollution

There are times when I wonder WHY is this a story? I have been leery about running articles about the environment because the state of it is so bad that any comments would be dreary. What with the Gulf Spew, Russia catching on fire and the nuclear accident in Japan, is there anything left to say? I saw this article earlier this morning and I thought, Ok this is a little different and I love Albatrosses. They are such  magnificent birds. Then I read the article and could not grasp the point of it. The headline seems pretty clear, but the body of the article seems not to support it. Read the whole thing at the site below:

Feathers tell century-plus tale of mercury pollution

Richard Black By Richard Black Environment correspondent, BBC News

Albatross feathers from museum specimens have allowed scientists to construct a record of mercury pollution dating back more than 100 years.

The feathers, from the black-footed albatross, contain traces of mercury that the birds picked up when they fed.

The species is endangered; and although fishing is the main cause, the team suggests mercury levels may have been high enough to impair breeding.

The study is published in Proceedings of the National Academy of Sciences.

The team analysed feathers from 54 birds kept in museums at Harvard University and the University of Washington in Seattle, US.

The oldest samples are 120 years old.

There was no trend in overall mercury concentrations over time.

But the level of methylmercury – a toxic form of the metal, formed often by bacteria, did show a rise.

Methylmercury is easily absorbed by marine lifeforms such as small fish; and predators of those lifeforms, such as birds, can end up with big concentrations in their tissue.

It can cause developmental defects in humans, and there is evidence that it can damage reproduction in birds and fish.

“People have looked at mercury levels using museum specimens before, but mostly in the Atlantic,” said Scott Edwards, a biology professor at Harvard who also curates the university museum’s ornithology collection.

“Ours is one of the first to look at patterns in the Pacific basin; this has the largest number of seabird colonies, has the most endangered colonies, and is under severe threat from mercury emissions from Asia.”

“They’re fantastic birds, and a very tractable species to study” Scott Edwards Harvard University

About half of the mercury going into the atmosphere comes from natural sources such as volcanoes.

Of the other half, the biggest source is coal-burning, with mercury ocurring as a trace element in many coal deposits.

New Energy Movement – Interesting Google find

This is a long story over a minor point, but bear with me. Google used to have a “Feel Lucky” icon on their choice bar that would take you to a random choice. They redid their algorithm to preclude this possibility when they realized that this was losing them money.  Originally I was excited by this. Yet it always turned out boring. Government pages, and the usual energy giants like Siemens. Over the years I have tried to continue this spirit by typing weird phrases in the Google box and again the results have been…well less. But this time I typed in NEW Energy and got some interesting hits. Here is one cool one.

http://www.newenergymovement.org/

Ere many generations pass, our machinery will
be driven by power obtainable at any point in the
universe. It is a mere question of time when men
will succeed in attaching their machinery to the
very wheelwork of nature.

—Nikola Tesla
The World We Envision
Clean, safe, abundant, inexpensive energy for all… stabilized climate… clean and healthy water, food, and air for all… beautiful blue skies over our cities… low-impact, sustainable forestry and agriculture… beautiful landscapes unspoiled by wires and smokestacks… recycling of virtually all wastes… rivers running free and natural… thriving sustainable local economies… living standards and education rates increasing… birth rates declining… a global culture of sharing… unleashed human creativity… a new and lasting era of world peace…

With a revolution in energy as the foundation of renewed and loving stewardship of our planet, we can transform our world into a beautiful and healthy home full of promise, opportunity, abundance, and peace for all of humanity.

Our Mission
The New Energy Movement acts to promote the rapid widespread deployment of advanced, clean, and sustainable energy sources across our imperiled planet. This transformation in the way our civilization generates and uses energy provides the best physical means to protect the biosphere, remediate ecological damage, and enhance the health and well-being of the global human family.

The New Energy Movement’s major priority is to educate the public, policymakers, and investors about the need to support research, development, and use of zero-point energy, magnetic generators, advanced hydrogen processes, and other little-known powerful energy technologies now emerging from inventors and scientists all over the world…

The Challenges

Critical and unprecedented challenges now face our civilization, inflicting a terrible toll on our people, our companion species, and the planet itself. If not reversed soon, they threaten to end human life on Earth.

Without a revolution in energy, we will not be able to act with the speed and scope demanded by the climate change emergency we face. With this revolution we will be able to create sustainable and just economic development required for world peace.

______________________________________________

Our survival will require
a vast and dramatic shift
in how human civilization
generates and uses energy.
