Study: Wind power soared in 2006

The wind power industry made big strides last year, according to a Worldwatch Institute report released late Thursday.

15,200 megawatts of new wind turbines were installed around the world last year, representing a 26 percent jump in global wind power capacity, according to the study.

By year's end, total wind power capacity exceeded 74,200 megawatts, enough to offset 43 million tons of carbon dioxide, the institute said.

Germany, Spain and the United States are currently the world's top wind power producers, putting out 60 percent of the global total, but the report says the alternative energy winds are shifting eastward. India and China were No. 3 and No. 5, respectively, in a list of countries installing new wind turbines. Senior Researcher Janet Sawin predicts the U.S. and China will compete for the top spot in window power output in the coming years.

You can access more details from the report at the Worldwatch Institute's Web site here.

Laws of Thermodynamics
by wylbur July 26, 2007 7:48 PM PDT
"Conservation of Energy". So another way to think about this is
74,200 Megawatts taken out of the earth's natural windflow
assuming 100% efficient conversion. Question: How many
megawatts can you take out of the wind before you start to change
the climate?

I've wondered about that myself
by billmosby July 26, 2007 8:05 PM PDT
If you get enough wind turbines in one place, is there some
quirk of aerodynamics or aerodynamics combined with moisture
evaporation/condensation that will act to change the winds they
depend on? I wonder if any simulations have been done.

Also, on a related note, I have noticed that solar cells are about
the color of asphalt. I wonder if they turn the sunlight that is not
converted into electricity into heat as efficiently as asphalt does?
Is there any implication for global warming enhancement? I
suppose it depends on the reflectivity of whatever was there
before you installed the solar panels.

Climatic effects of harvesting wind power

Wouldn't removing kinetic energy from the atmosphere contribute
to cooling?

Kinetic sculpture...

...also. Another reason to plant more trees, to offset global warming. Oh, wait, we humans shouldn't have an effect on the environment, should we?
Closed system
by billmosby July 26, 2007 10:22 PM PDT
Not if it is a closed system. The same sunlight is powering the
whole system, the kinetic energy taken out matches that which
shows up as a temperature increase at the point where the energy
is used, which is not all that far from the wind turbines generally.
So it's probably a wash from that standpoint, the only question is if
you get enough wind turbines in an area, do they change the winds
enough to affect their own operations in some way?

Wind power + Zonbu $99 green PC?
by mrzonbu July 30, 2007 3:52 AM PDT
I've been playing with the Zonbu "green" PC to see if I can use it to replace my power hungry desktop. So far the answer is a yes.

All this has me thinking about alternate power sources to drive the little 15W box and really reduce my energy footprint.

To read more about my experiences with the green PC, check out my blog:

R2 AUTOMATION INC.

R2 AUTOMATION INC. has just lunched a new patent technology that will revolutionise the world. After years of Investment R2 AUTOMATION INC. has create a waste to energy machine. The R2 Automation plant can take 100 thousand tons of (MSW) waste recycle it down to 15 thousand tons, it separates the plastics and metals (which can be re-used or recycled) and in the process also produces 8.5 MW of electricity!! R2 Automation Inc. system leaves 0 emission, no odor, and produces carbon credits for every ton the recycle. R2 Automation Inc. is currently in talks with municipalities all across the country. R2 Automation Inc. Hopes the first system will be launched in the Detroit Michigan area...

R2 Automation, Inc. Has A Turnkey Program For Producing Clean Energy From MSW Nationally, With Zero Emissions
March 30, 2009

R2 Automation, Inc. has a turnkey program for producing clean energy from MSW nationally, with zero emissions, R2 Automation's technology sterilizes and reduces Municipal Solid Waste (MSW) by over 85%, recovers recyclable material and eliminates the source of methane gas from the waste stream, and creates a clean cellulose fuel from which it creates electricity.

(PRWEB) March 26, 2009 -- R2 Automation, Inc. has a turnkey program for producing clean energy from MSW nationally, with zero emissions, R2 Automation's technology sterilizes and reduces Municipal Solid Waste (MSW) by over 85%, recovers c and eliminates the source of methane gas from the waste stream, and creates a clean cellulose fuel from which it creates electricity. The self-contained unit will process approximately 100,000 tons/year of waste, with de minims emissions, noise, and odor. From 100,000 tons of waste, the unit will separate recyclables, generate 8.5MW of continuous power output (annually providing approximately 52-65 million KWh of saleable power), and output approximately 15,000 tons of sterile, inert waste that maybe destined for the landfill.

Each modular for R2 Automation, is self-contained unit uses steam autoclaving technology that sterilizes the waste stream and creates the fuel for electricity generation. By extracting valuable components for re-use, the system promotes sustainability. By removing cellulose from the waste stream, the system eliminates the greatest landfill source of methane, a dangerous greenhouse gas.

Use of R2 Automation's system will extend the life of current landfills, and eliminate the need for new ones. Termed a "virtual landfill," because the system receives and properly manages MSW, without requiring landfill space, R2 Automation's technology creates additional benefits including a reduction in the environmental impact and cost of transporting waste.

The R2 Automation has been proven in the operation of a two-year commercial demonstration plant in the United Kingdom, and will soon be in full commercial operations in the UK and Brazil.
