Study Confirms LED Life Cycle More Efficient than Incandescent

LEDs are by far more efficient than incandescents and even CFLs while being used as a light source, but what about over their entire life cycle?  Until a recent study, there had been doubts that the technology could claim the how to buy viagra in budapest title of "most efficient" once you factored in production.

A new study conducted by Siemens Corporate Technology Centre for Eco Innovations and released by lighting company Osram claims to put those doubts to rest. The study compared the life cycle energy use of one 25,000-hour LED lamp to that of 2.5 10,000-hour CFLs and 25 1,000-hour incandescents.

The report states that the energy needed to make, ship, install, use and then recycle LEDs was about equal to CFLs and much less than incandescents.  While the report didn't go into the technical details of how does cialis work the study or release specific numbers, Osram says it will release all of that information in the fall with support by three independent analysts.

Boosting Energy Efficiency Could Save U.S. $1.2 Trillion

McKinsey & Co. have released another report about climate change, but this time they're putting it in motivating terms:  money, money, money.  The consulting firm has calculated the amount of cash the purchase real name brand viagra country could save over the next decade if we fully commit to becoming more energy efficient, and the amount is huge:  $1.2 trillion.

Of course, this savings can only be accomplished through a large investment in weatherizing homes, retrofitting buildings, efficiency education and government initiatives, etc. - costing about $520 billion over that same decade.  So, you're actually looking at a net savings of $700 billion, but that's still a nice big incentive to cut our energy consumption and help the planet at the same time.

The firm states that homes and businesses could trim 28 percent off their current energy bills and industries could trim 20 percent.  The report doesn't factor in transportation, just "stationary" uses of energy, but the study shows that through that large investment in efficiency, the country could slash 23 percent of its energy demand by 2020 and prevent the emissions of 1.1 gigatons of viagra online pharmacy usa greenhouse gases yearly, the equivalent of taking the professional levitra online U.S. passenger fleet off the road.

As ecogeeks already know, a large portion of wasted energy is consumed by vampire power loads.  The study revealed that efficiency standards that prevent our electronics from sucking energy while not in use could lead to energy savings equal to the yearly electricity consumption of the Netherlands.

Navy Putting $33 M Into Hybrid Destroyers

It's not exactly your typical hybrid vehicle. The DDG 51 is a naval destroyer that's been in use for quite a while now. And though the US government has some newer, fancier ships, they cost a pretty penny. So the DDG 51's are getting some upgrades. Better sonar and viagra canda radar, upgraded communications equipment and, yes, a hybrid-electric drive.

These destroyers have a top speed of 35 miles her hour, but, like most gas guzzlers, they generally go much slower than that. However, their engines aren't well suited to these slower speeds. So GE and General Atomics have joined together to put in an electric drive system that basically uses the ships electrical generators to move it along at low-speeds. The electric drive can also be used to perform low-speed maneuvering when the ship is anchored. The result is a 16% decrease in fuel use for the visit our site viagra brand DDG 51 which translates into 12,000 BARRELS of oil per ship per year.

Yeah, that's more than what you'll save by switching to a hybrid. But it didn't cost you 33 million dollars did it?


Yahoo Data Center Will Be Powered By Niagara Falls

Companies like Google and IBM are trying to lead the world in cutting-edge, efficient data centers.  Not to be outdone, on Tuesday Yahoo announced they're hoping to change to future of data centers as well.  The company unveiled plans to low cost viagra build one of the world's most efficient data centers in Lockport, NY and the details do sound pretty exciting.

The data center will be powered mainly by hydroelectric power from Niagara Falls, with 90 percent of that energy going towards powering the servers.  The center itself will be built to resemble a chicken coop, using 100 percent outside air to cool the servers, a task which typically gobbles up 50 percent of a data center's energy supply.  And the company expects the yearly PUE average to be 1.1 or better.

In addition to building this super-efficient data center, the company also committed to reducing the carbon footprint of tramadol in mexican pharmacies all their data centers by 40 percent by 2014.  They intend to accomplish this through using more renewable energy sources to power their data centers, implementing more efficient building designs and improving the free sample cialis efficiency of the servers themselves.

Another major commitment made in this announcement was that the company would cease purchasing carbon offsets and was aiming to reduce their carbon impact directly through decreasing energy consumption.  We would love to hear of more companies relying less on offsets and more on energy-saving improvements.

NYT Op-Ed Defends IGCC


An interesting op-ed from yesterday’s New York Times discusses clean coal.  I encourage our readers to read the piece themselves, but for those who want the short version, here’s a summary:

1. FutureGen, a federal program to design a zero-emission clean coal power plant is not going to work for two main reasons:

  • Zero-emission clean coal technology doesn’t exist, and might take a really long time to get here
  • Huge, politically charged federal research projects like these have not historically accomplished anything
2, If the government is going to support some kind of clean coal, it should support IGCC (Integrated Gasification Combined Cycle), for three reasons:
  • IGCC technology already exists
  • Once Washington passes a cap-and-trade law of some kind, the cost of carbon will make IGCC cost-competitive
  • To generate the same amount of electricity as regular coal plants, IGCC plants use only one third of the coal, which means they naturally cut GHG emissions by two thirds
An important take away message is levitra plus that when people throw around the term “clean coal”, they may be referring to different things.  Here we see two distinct technologies – one theoretical, nonexistent technology that promises zero emissions by sequestering all the carbon dioxide underground, and another, existing technology which squeezes more power out of online levitra prescriptions less coal by gasifying it first (this also makes it easier to sequester the CO2, but we’re not even getting into that now).

However, though I agree with the author that the government should be worrying about practical solutions rather than (in his words) pie-in-the-sky ideas, I think he overplays the viagra discussionsdiscount priced viagra benefits of IGCC.  True, the technology exists, but it’s extremely expensive.  Carbon legislation isn’t going to make it cheaper, it’s just going to make everything else really expensive too.  You can’t really expect every utility to pour money into a technology that, while proven, is still wet behind the ears.

But – and this is the author’s main point – the government can, and it should.
