Behold the Gorgeous Solar Farms of Le

Mées, France

  • May 27, 2011 • 12:10 pm PDT

The energy company Efinity opened two new solar-power farms in Le Mées in north-central France this month. They’re huge. Together they occupy 89 acres, generating enough electricity for 9,000 families. They were also designed with the landscape in mind. The panels were installed without concrete foundations, which means when their 20-year lifespan is over and they’re removed, there will be healthy land left behind, and grasses are being planted so sheep can graze among them.

But what’s most remarkable about these solar farms is that they’re really aesthetically pleasing. Set on the rolling hills, they look like some sort of Frank Gehry installation. Carbon aside, they’re just much nicer to look at than a coal plant.

Americans Waste Energy Just Getting Out Of Bed – Even while they sleep

This is a great blog post. I will only quote part of it because its point is that we must decentralized our energy sources to avoid losses. But I just want to focus on the losses part. Next week we start another meditation. Have a great Memorial Day weekend. (I realize you can not  see the entire graphic below. More reason to go read the source.)

It’s Not Just Alternative Energy Versus Fossil Fuels or Nuclear – Energy Has to Become DECENTRALIZE

dot dot dot

This basic trend can be seen around the globe with many energy sources. We’ve most likely already found and tapped the biggest, most accessible and highest-E.R.O.I. oil and gas fields, just as we’ve already exploited the best rivers for hydropower. Now, as we’re extracting new oil and gas in more extreme environments – in deep water far offshore, for example – and as we’re turning to energy alternatives like nuclear power and converting tar sands to gasoline, we’re spending steadily more energy to get energy.

For example, the tar sands of Alberta, likely to be a prime energy source for the United States in the future, have an E.R.O.I. of around 4 to 1, because a huge amount of energy (mainly from natural gas) is needed to convert the sands’ raw bitumen into useable oil.

Professor Charles Hall of the SUNY College of Environmental Science and Forestry provides the following graphic to illustrate the point:

 

“Balloon graph” representing quality (y graph) and quantity (x graph) of the United States economy for various fuels at various times. Arrows connect fuels from various times (i.e. domestic oil in 1930, 1970, 2005), and the size of the “balloon” represents part
of the uncertainty associated with EROI estimates.

The take away message from the graph is that the energy return on investment was very high for oil in 1930, but it is very low today, since the cheap, easy-to-get-to (and less dangerous) oil is gone.

America uses 39.97 quads of energy, while it wastes 54.64 quads (i.e. “rejected energy”).

As CNET noted in 2007:

Sixty-two percent of the energy consumed in America today is lost through transmission and general inefficiency. In other words, it doesn’t go toward running your car or keeping your lights on.

Put another way:

  • We waste 650% more energy than all of our nuclear power plants produce
  • We waste 280% more energy than we produce by coal
  • We waste 235% more energy than we produce by natural gas (using deadly fracking)
  • We waste 150% more energy than we generate with other petroleum products

The Department of Energy notes:

Only about 15% of the energy from the fuel you put in your tank gets used to move your car down the road or run useful accessories, such as air conditioning. The rest of the energy is lost to engine and driveline inefficiencies and idling. Therefore, the potential to improve fuel efficiency with advanced technologies is enormous.

According to the DOE, California lost 6.8% of the total amount of electricity used in the state in 2008 through transmission line inefficiencies and losses.

The National Academies Press notes:

By the time energy is delivered to us in a usable form, it has typically undergone several conversions. Every time energy changes forms, some portion is “lost.” It doesn’t disappear, of course. In nature, energy is always conserved. That is, there is exactly as much of it around after something happens as there was before. But with each change, some amount of the original energy turns into forms we don’t want or can’t use, typically as so-called waste heat that is so diffuse it can’t be captured.

Reducing the amount lost – also known as increasing efficiency – is as important to our energy future as finding new sources because gigantic amounts of energy are lost every minute of every day in conversions. Electricity is a good example. By the time the energy content of electric power reaches the end user, it has taken many forms. Most commonly, the process begins when coal is burned in a power station. The chemical energy stored in the coal is liberated in combustion, generating heat that is used to produce steam. The steam turns a turbine, and that mechanical energy is used to turn a generator to produce the electricity.

The main point being we waste energy to make energy. There is something wrong with that. It really means that resources are not free. But that is another post. More Tuesday.

Militaries Waste Huge Amounts Of Money – In everything they do

Posted on by
Reply

Let us put aside the fact militaries themselves are a huge waste of money. It is estimated that for every 1 $$$ the US for instance spends on a bullet they get 75 cents in return. That is just if it sits on the shelf. If it is used of course it is worth nothing. Not to mention that lavishing spending on militaries brought Empires from the Egypt to the Soviet Union’s down. But the USA’s Military wastes energy like there is no tomorrow. The worst offenders of course are the Airforce and the Navy. The Airforce in particular spews kerosene byproducts into the upper atmosphere where they do the most harm and the Navy because they burn warm asphalt at sea. Not to mention the nuclear issues both as weapons and power sources. But think about our main battle tank. It is as big as a modest 2 story house and it runs on diesel. So the idea that they want to go to zero energy use is great. But I got my doubts.

U.S. Army Launches Plan to Make All Military Bases Net Zero

Posted by Ggw Admin on Apr 19, 2011 in Blog | 0 comments

Army Vision for Net Zero, Fort Bliss, net zero, renewable energy, U.S. Army, U.S. Military, Waste Reduction, water conservation

Over the past couple of years, the U.S. Army has announced several initiatives ranging from solar-powered tents for troops to hydrogen-powered tanks, however this is their most ambitious program yet. With the help of the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), the U.S. Army is aiming to have all Army installations across the country be net zero.


Army Vision for Net Zero, Fort Bliss, net zero, renewable energy, U.S. Army, U.S. Military, Waste Reduction, water conservation

With funds from the DOE’s Federal Energy Management Program (FEMP), the “Army Vision for Net Zero” program will aim to meet mandates to reduce energy as a result of Executive Order 13514. The order calls for all new buildings to be net zero energy by 2030, and it dictates a 30 percent reduction in water use and a 50 percent reduction in waste that goes to landfills. On top of that, the National Defense Authorization Act also mandates that the Army produce or acquire 25 percent of its energy from renewables by 2025.

“The first priority is less,” Assistant Secretary of the Army for Installations, Energy Environment Katherine Hammack said. “If you use less energy, you don’t have to buy as much – or you don’t have to make as much from alternative energy sources or renewable energy sources. So if you look at energy, that is a focus on energy efficiency. If you’re talking about water, then that’s water conservation. Or even if you’re talking about waste, that’s reducing the amount of waste we have in the steam.”

The program already has a poster child in the form of Fort Bliss. The military base boasts solar daylighting in the dining facility, warehouse and gym, energy-efficient windows, utility monitoring and control for heating and air-conditioning systems in approximately 70 buildings, and plans to increase the on-site hybrid waste-to-energy/concentrating solar power plant from 90 to 140 megawatts. The City of El Paso has committed to provide 1 million tons per year of municipal solid waste, which will be transformed into energy by the base.

“The Army’s net zero vision is a holistic approach to addressing energy, water, and waste at Army installations,” Kingery said. “We look at net zero as a force multiplier for the Army that will help us steward our resources and manage our costs.”

Considering that defense is a massive cause of national debt, the plan serves two purposes – reduced spending and “greening” national security. If the military can get on board with renewable energy, it makes you wonder why other areas of government are having such trouble.

(PhysOrg.com) — This flow chart of the estimated US energy use in 2009, assembled by the Lawrence Livermore National Laboratory (LLNL), paints a pretty sobering picture of our energy situation. To begin with, it shows that more than half (58%) of the total energy produced in the US is wasted due to inefficiencies, such as waste heat from power plants, vehicles, and light bulbs. In other words, the US has an energy efficiency of 42%. And, despite the numerous reports of progress in solar, wind, and geothermal energy, those three energy sources combined provide just 1.2% of our total energy production. The vast majority of our energy still comes from petroleum (37%), natural gas (25%), and coal (21%).

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.

Wasted Energy – Very cool blog

Posted on by

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.

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.
