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.

We Even Waste Light During The Day – That’s right

The people of the US actually turn on more lights then they need and make there eyes worse from the glare. If you don’t believe me listen to this professor.

Proposal Essay: Less wasted light equals more energy savings

Posted on April 18, 2011 by David Apperson

The UAF campus uses electricity.  Some of the electricity is used to power fluorescent light bulbs which are much more efficient than incandescent bulbs but because they exist as a load in the power grid, use energy.  How much energy is being used by these lights, is it more than is necessary, and how bright to classrooms and computer labs need to be?  In 2010, UAF created its Office of Sustainability to utilize the $20 per student fee towards sustainable projects.  The goal is to supply the necessary funds to make sustainable projects happen but the projects must be cost effective with realistic financial return periods.  Although bright rooms are convenient, the UAF sustainability club should lobby the Chancellor and Facilities Services to implement a program that systematically removes bulbs from over-lit rooms because it will reduce the energy use of the UAF campus, make indoor conditions more comfortable, and save money.

The simplest way to reduce the energy use for lighting is to remove unnecessary bulbs.  Before someone begins pulling random lights from their fixtures at will, some simple calculations can be done to get “back of the envelope” numbers for a cost-benefit analysis.  The following calculations will use some simple energy units, the kilo-Watt (kW) and the kilo-Watt-hour (kWh).  A kW is a measurement of Power and is defined as 1,000 joules per second, how quickly work is being done.  A kWh is a measurement of energy, a fairly large amount of energy at that, being the amount of work by a one kW source for one hour.  Electricity is sold in kWh, because it doesn’t matter how fast someone or something is using the electricity but how much of it they are using.  Light intensity can be measured in lumens or foot-candles.  A lumen is a measure of the power of light perceived by the human eye and the foot-candle can be considered as the amount of light falling on a surface, being defined as one lumen per square foot.

The first thing to be determined is whether or not rooms are over lit.  If they are, then energy is being wasted.  The U.S. Occupational Safety and Health Administration (OSHA), recommends that in an office setting, the light intensity be between 20 and 50 foot-candles (OSHA).  As I write this essay, I am sitting in the Students of Engineering Computer Lab (SOECAL) in Duckering.  The room is quite bright and approximately 20 ft by 40 ft and holds 15 light fixtures, each containing three fluorescent bulbs.  The bulbs are GE Ecolux Starcoat bulbs consuming 32 Watts and producing 2800 lumens a piece (light bulb).  To determine if this particular room is over lit, the following calculation is made:

It appears that the SOECAL lab is over lit by three times the amount of recommended light for a work office, perhaps other similar classrooms and computer labs are as well.  Since we can assume the SOECAL lab and many other rooms are over lit, it can also be determined how much energy is being wasted and how much it is costing.  The following calculations are performed considering a single bulb for a single hour.

In the room where he is writing no less. More tomorrow.

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.

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.

Idling Vehicles Are Costing Billions – Cops, firemen and farmers alike

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.

http://www.afdc.energy.gov/afdc/vehicles/idle_reduction.html

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.

Seems like we waste energy even when we throw it away. More tomorrow.

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.

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

Posted on by

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.

The first and only organization working solely on the elimination of natural gas flares and venting! Stop the flares is organized to stop flaring by elevating awareness, increasing research and implementing proven solutions to get results. Stop the Flares will eliminate all flares worldwide by the 2020.

What are flares?

What is natural gas?

Why is methane flaring bad for you?

How does Flaring Methane affect the price of energy?

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).
Wasting fuel increases the cost of energy for everyone!

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.
