Excellent info on wind turbines for the home.

Many golden tidbits of essential information including wiring
efficiency differences between AC and DC, why AC turbines are a
better deal with a rectifier located where your juice does the
work or goes into a battery bank, why odd numbered blade
turbines are better
HTML http://www.pic4ever.com/images/128fs318181.gif,
a good
discussion of blade materials, angles and designs and also a
discussion of turbine towers.

The sun will weaken PVC blades and high speed winds will DESTROY
them. :P Do NOT buy PVC blades.
In fact, ANY plastic is TOAST under daily sunlight after a
while. I suppose fiberglass would work but they would be much
heavier than metal ones. Heavier blades mean higher wind speeds
to get them moving. So, if you are in a low wind area,
fiberglass is out too. 8).
I learned a lot from this video. The discussion of the charge
controller, inverter and how EXACTLY they are connected was
great. Also, the "dump load" feature to keep a wind turbine from
wind milling was particularly enlightening.

01/22/2015 02:56 PM [move]China Leads World On Wind
Additions Again; Offshore Wind Creates Double the Jobs As
Drilling[/move]
SustainableBusiness.com News
The results are in for wind industry growth in 2014, with the US
and China continuing their leadership positions.
Developers in the both countries (and Germany) rushed to get
projects in the ground before incentives declined or expired
-leading to 4.7 gigawatts (GW) added in the US and an impressive
20.7 GW in China, according to Bloomberg New Energy Finance
(BNEF).
HTML http://www.createaforum.com/gallery/renewablerevolution/3-280914173454.gif
In the US, projects had to be started by the end of 2014 - which
means a good year ahead
HTML http://www.runemasterstudios.com/graemlins/images/2thumbs.gif
-
and in China, the feed-in tariff will soon be cut. :P
Last year, capacity grew 38% in China, where a total of 96 GW of
wind is now installed, says BNEF. After leading the world with
16 GW installed in 2013, China's government raised the target to
200 GW by 2020.
HTML http://www.pic4ever.com/images/maniac.gif
;D
Even though China leads on capacity, the US pumps out more wind
energy.

The other top countries for wind additions are Germany (3.2 GW),
Brazil (2.7 GW) and India (2.3 GW).

biggest wind farm in the world so far.
Jobs From Offshore Wind
Just as the US is about to get its first - if tiny - offshore
wind farm and Republicans get ready to push for extensive
offshore oil drilling in the Atlantic, another report shows the
advantages of offshore wind.
HTML http://elqahera-trading.com/home/wp-content/uploads/2012/04/dollar-sign-thumbnail1.jpg<br
/>
Offshore wind would create double the jobs and double the energy
as offshore drilling in the Atlantic Ocean, reports Oceana,
while drilling would actually threaten the 1.4 million jobs in
fishing, tourism and recreation. And the threats begin with oil
exploration - where seismic airguns blast the ocean floor from
Delaware to Florida, harming millions of fish, dolphins and
whales.
"Unlike offshore drilling, offshore wind provides power directly
to coastal communities where we need energy the most, without
the risk of oil spills or carbon pollution," says Andrew
Menaquale, author of the report and energy analyst at Oceana.
"It's time for the US to use the lessons learned from more than
20 years of offshore wind development internationally and apply
them to generating clean, renewable energy off our coasts."
Findings include:
HTML http://www.pic4ever.com/images/reading.gif
•In 13 years, offshore wind could generate more energy than all
economically recoverable offshore oil and gas resources.
•Gradual offshore wind development for the next 20 years, would
supply electricity to over 115 million households.
•Extracting all recoverable oil would meet 5 months of demand,
and 10 months of gas demand at current consumption rates.
•The Atlantic Ocean contains less than 4% of US oil reserves and
less than 3% of gas reserves.
A previous study shows offshore wind could power the entire
Atlantic coast, while creating 300,000 jobs, and would also
protect the coast from devastating hurricanes.

Photoessay: A Day in the Life of a Wind Farm Operator
Christine Duval, First Wind
January 23, 2015
Have you ever wondered what it takes to run a wind farm? You’ve
seen all the amazing photos taken from the tops of turbines, but
do you know what the technician is actually doing up there?
A photographer followed around the crew at the Bull Hill Wind
farm in Maine. Here’s a glimpse into their daily lives on the
job.

Thank you, Christine Duval. I love to see people making a decent
living working on behalf of future generations on jobs that will
never be outsourced.
I predict that, in the near future, both the ten minute climb
and the ten minute descent will be eliminated by a one man
electric winch elevator.
These "winches" are old technology used by scaffolding workers
that wash skyscraper windows. It is simply a drill that attaches
to a fitting on the scaffolding frame and cables (you need two
men running a drill on both ends to raise the scaffolding evenly
- a tricky process if one drill is running faster than the other
- not for the feint of heart).
I'm certain a better version for wind turbines will be developed
to enable quicker access. Time is money.

Wind power to create 4,200 Maine jobs this year, boosts state
economy

in Bingham · Bull Hill · Development · Economy · Hanc ock ·
Maine · Mars Hill · Oakfield · Rollins · Stetson · The Future of
Wind
— 6 Jan, 2015
A new economic report predicts that the wind energy industry
could create as many as 4,200 jobs in the state of Maine alone
in 2015.
In addition, the report demonstrates that the industry has
already invested nearly $550 million into the Maine economy
since 2006 and will invest another $750 million in the next few
years.
The analysis of wind energy in Maine released today shows that
the industry has made a significant positive impact on the
state’s economy, not only in terms of investment, but also in
terms of creating jobs. The study states that the industry has
been employing more than 1,500 people per year and helping to
open new markets for Maine companies.
Conducted by Charles Colgan, Ph.D., and the Maine Center for
Business & Economic Research at the University of Maine in
conjunction with Wind for Maine and the Maine Renewable Energy
Association (MREA), the report’s major findings include:
◾New investment of nearly $1.28 billion between 2006-2018;
◾$1.14 billion in employee earnings over the same period;
◾Creation of 1,560 jobs per year, peaking in 2015 at
4,200; and
◾Development of new markets for 23 Maine-based companies
that led to nearly $89.6 million in sales in 2011-2013 and 390
jobs in Maine.
Wind for Maine and MREA announced the results of the report at a
press conference today and in a press release.

Wind Intermittency Is a Myth, says AWEA
HTML http://www.pic4ever.com/images/47b20s0.gif
SustainableBusiness.com News
The Achilles Heal for wind energy is intermittency, or that's
what we have been told.
We need coal, nuclear and gas for reliable, baseload power, is
the common refrain, but that's a myth, according to the American
Wind Energy Association (AWEA).
Instead, wind contributes to the stability of the grid, they
say, and can be more reliable than conventional energy sources.
Fluctuating supply and demand is fundamental to the grid - with
or without wind power.
Fluctuations from any given power source are not what's
important to grid operators, they care about the total supply
and demand at any given moment. Variations in wind energy happen
slowly and can be easily smoothed out - they are actually less
problematic than fluctuations in conventional energy sources
because they can be predicted in advance. And the more wind
energy that's added to the grid, the less variable the resource
as a whole becomes.
When conventional energy sources go down, they tend to drop
suddenly and by a lot.
This means less - not more - reserve capacity is needed as a
backup for intermittent wind. In Texas, grid operator ERCOT, for
example, shows back-up for wind adds four cents to utility
bills, compared to 76 cents for hedges against power plant
outages, according to AWEA.
Out of 10 gigawatts of capacity, only 50 megawatts of
fast-acting reserves must be ready to compensate for wind
variations, says ERCOT. MISO, the grid operator in the Midwest,
needs "little to no" fast-acting reserves.
HTML http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif
AWEA notes that wind variability does increase the need for more
slower-acting reserves, but those are less expensive sources of
power.
HTML http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif
"Conventional power-plant failures most often happen in a
fraction of a second with no warning; the variability of wind is
both gradual and predictable," Michael Goggin, AWEA's Research
Director told Midwest Energy News. "Gradual changes in wind
output are relatively easy for grid operators to accommodate. On
the other hand, rapid changes in electricity supply caused by
traditional power plant failures require very fast-acting
reserve generation. 24/7, you don't know when a traditional
power plant will go down. With wind you can do forecasting, you
know tomorrow between 2 or 3 p.m. there will be a reduction."
HTML http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif
Therefore, AWEA says the focus on the need for large amounts of
"baseload" power is misleading, as is the need for lots of
energy storage. The combination of power sources on the grid
serves that function.
HTML http://www.desismileys.com/smileys/desismileys_0293.gif
In fact, this is an argument for a diverse, balanced grid that
runs on many energy sources. Wind energy helps build a more
reliable and balanced electricity portfolio.
HTML http://www.freesmileys.org/emoticons/tuzki-bunnys/tuzki-bunny-emoticon-005.gif
More than a dozen studies by US grid operators and the
Department of Energy show that wind energy can reliably supply
at least 20-30% of our electricity, and some say, 40%.

World Wind Industry Grows 44% in 2014 ;D
SustainableBusiness.com News
2014 was a record-breaking year for the wind industry as it grew
44% worldwide, says the Global Wind Energy Council.
The industry added 51.5 gigawatts (GW) bringing the world
cumulative total to 369.6 GW.
China, still the leader, set its own record by installing 23.4
GW - almost half the world's new capacity, and more than any
country has added in one year. China has 115 GW of wind farms.
Europe added 12.8 GW, and Germany installed almost half of that
with 5.3 GW of new wind, growing 58% from 2013. Germany now has
38 GW of onshore wind and 2.4 GW of offshore wind. Renewable
energy currently supplies 25.8% of the country's electricity.
European countries are now connected to nearly 2,500 turbines as
part of 74 different offshore wind farms, reports the European
Wind Energy Association. Total installed capacity there reached
8,045.3 MW in 2014.
Other notable additions:
•US added 4.9 GW
•Latin America added 3.7 GW, mostly in Brazil (2.8 GW) - the
significant newcomer
•India added 2.3 GW
Denmark had a watershed year, with wind producing 39% of its
electricity, as did Scotland at 32%, and the UK, Spain,
Portugal, and Germany get at least 10% from wind.
Wind energy now accounts for about 5% of global electricity
demand.
