UNITED STATES: Figures from the AWEA reveal the US installed a
capacity of 835MW in the first half of 2014, compared to just
1.6MW in the same period of 2013.
Last year's low figure was as a result of uncertainty in the
sector due to the delayed extension of the production tax credit
(PTC).
Texas saw the greatest increase in capacity, with 400MW
installed followed by Nebraska (201MW) and Michigan (136MW).
The southern US state was helped by the 218.3MW Panhandle 1
project being commissioned in the second quarter.
According to AWEA, the US now has an installed capacity of
61.9GW from 46,300 turbines.
Texas is set to continue leading the way with capacity, as over
8GW in projects are currently under construction in the state.
In total, the US has 14.6GW of wind under construction across
106 projects in 21 states. [img width=60

New Cable Technology Can Carry Twice as Much Power from Offshore
Wind Farms ;D
Patrick Winters, Bloomberg
August 21, 2014
SNIPPET:
ABB Ltd. said a power-cable technology that allows offshore wind
farms to transmit more than twice the energy of current set-ups
will boost orders at the company’s power systems division in
coming years.
“It’s on the list of ABB’s most important breakthroughs in the
last five years,” Chief Technology Officer Claes Rytoft said in
an interview, adding that rival technologies are at least some
years behind. “We know about projects that have not moved
forward because they are missing this.”
The technology will spur the construction of even bigger
offshore wind farms by doubling the power capacity of cable
connections to about 2,600 megawatts from 1,000 megawatts today,
making it the most powerful subsea connection system in the
world, Rytoft said. It includes high-voltage power cables,
joints and terminations.

Excellent! Ocean currents are THE greatest source of untapped
24/7 base load quality Renewable Energy there is. AND those
currents (that will never stop as long as the earth continues to
rotate) are close to over 90% of the major concentrations of
human population known as COASTAL CITIES.
HTML http://www.createaforum.com/gallery/renewablerevolution/3-191213230928.jpeg
Within a 130 km of every major coastal city in the world is
enough undersea current to power them many times over, at base
load quality 24/7, immune to ocean surface storms, and with very
low transmission losses due to the short distance from the
harvesting point to the user.

Water, Energy and Waste Sustainable Development in Large Cities
[img width=640

There is no doubt that humans in general, and those concentrated
in cities in particular, are responsible for much of the massive
demand for potable of water and energy. There is also agreement
that this demand is, at present not healthy for the biosphere in
general and humans in particular. There is too much waste,
inefficient energy use, lack of renewable energy infrastructure,
pollution from fossil fuels and inefficient water use as well.
In summary, there is a consensus among knowledgeable and
observant people in the reality based community that our present
trajectory in the above issues is unsustainable.
The solution requires the phasing out of all fossil fuels and
nuclear fission power plants and replace them with Renewable
energy. This energy needs to be harvested within 100 miles or
less from the highest energy users on the planet, the large
cities, in order to have lower transmission and infrastructure
costs.
The energy must be baseload quality 24 hours a day with wind and
solar to supplement demand spikes along with pumped water
storage energy, fuel cell or battery storage technologies.
The renewable energy source that is best suited on a global
scale because it is constant, powerful and close to the major
cities is the energy from ocean currents.
Observe the two maps below.

Now look at the one below where I merged the two.
[img width=640
height=380]
HTML http://www.createaforum.com/gallery/renewablerevolution/3-191213230928.jpeg[/img]
The energy is renewable, does not disturb the biosphere or
hydrosphere and can completely replace the polluting energy we
now suffer from. The densely populated areas have this powerful
source nearby.
Ocean currents have far more energy potential than ocean tides.
The tides alone are estimated to have a potential tidal stream
energy capacity of over 120GW globally. Using both plus wind and
PV would make a 100% Renewable Energy transition to the 18TW the
planet required feasible with technology we now have.
Just in the UK alone, the marine power resource is estimated to
be more than 10GW, representing about 50% of Europe’s tidal
energy capacity.
In the USA a project is now in the works to provide wind turbine
power to the East Coast for up to 1.9 million households. When
built out, the Atlantic Wind Connection (AWC) backbone will
stretch 350 miles off the coast from New Jersey to Virginia and
will be able to connect 6,000MW of offshore wind turbines.

Now look at where those wind turbines will be and realize that
undersea turbines can be placed close by and save on cabling the
energy to the shore. Much more energy can be harvested 24 hours
a day from the ocean current. Sharing energy transmission cables
from wind and ocean current turbines will save millions of
dollars and hasten the transition to 100% clean energy.

As the new, clean energy replaces dirty energy, full
electrification of the economies to eliminate the internal
combustion engine for power plants, vehicles and factories will
clean the air in large cities.
With plenty of renewable energy to electrify the planet and
eliminate the internal combustion engine pollution, the
worldwide potable water problem can be solved anywhere on the
planet that the relative humidity is above 23% (any place it is
not a desert climate) by extracting water from the ambient air.
The waste water can, given all the ocean current energy, be
processed for agricultural fertilizer (eliminating petrochemical
fertilizers).
In this way, we will imitate the biosphere in turning our waste
into a nutrient that benefits all life on earth, not just
humans.

Wind Technologies Market Report
[img width=640
height=380]
HTML http://csmres.co.uk/cs.public.upd/article-images/Wind_turbine_smiley_shutterstock_28691215.gif[/img]
After modest growth in 2013, total installed wind power capacity
in the United States now stands at 61 gigawatts (GW), which
meets nearly 4.5 percent of electricity demand in an average
year, according to the 2013 Wind Technologies Market Report,
released today by the Energy Department and its Lawrence
Berkeley National Laboratory. The report also found that wind
energy prices – particularly in the Interior region of the
United States–are at an all-time low, with utilities selecting
wind as a cost-saving option.
HTML http://www.createaforum.com/gallery/renewablerevolution/3-200714183515.bmp
With utility-scale turbines installed in more than 39 states and
territories, the success of the U.S. wind industry has had a
ripple effect on the American economy, spurring more than $500
million in exports and supporting jobs related to development,
siting, manufacturing, transportation and other industries.

How to Build a Wind Turbine From Scratch ;D
Thanks to filmmaker Jake Beed and the Action4Climate video
competition, you can have a first-hand look at what it’s like to
build a wind turbine from scratch. In If You Build It, watch a
group of young Canadians strive for a more sustainable way of
life by figuring out how to generate their own power via a
homemade wind turbine.
With little to no prior knowledge or experience, the group finds
help in the surrounding community’s skill sets that all come
together to create a moment that will last for as long as the
wind blows. This film is inspiring. It shows how you can build a
community by building a wind turbine and that passion is the key
ingredient to getting things done.
Renewable energy deployment is key to solving global energy
issues. Especially in energy poor countries, it’s vital that
communities embrace clean energy and work on strategies to keep
the power generation locally owned.
One great example is in the Dharnai village in Bihar, one of
India’s poorest states. The community is now lit-up by a
community-owned solar-powered micro-grid. Dharnai is the first
village in India where all aspects of life are powered by solar.
The 100 kilowatt (kW) system powers the 450 homes of the 2,400
residents, 50 commercial operations, two schools, a training
center and a health care facility. A battery backup ensures
power around the clock.
“If we are to end extreme poverty, we must tackle energy
poverty,” said World Bank Senior Director for Energy &
Extractives Anita Marangoly George. “With 1.2 billion people
still living without electricity across Sub-Saharan Africa and
South Asia, it’s clear where our work will be focused for the
foreseeable future. Our priority is to find the cleanest energy
solutions to meet local needs in the smartest ways possible.”
The Action4Climate video competition received more than 230
entries from 70 countries from students inspired to share their
climate change stories. To watch other Action4Climate videos,

This Wind Turbine Is Bringing Clean Energy to New Heights

Written by Lorraine Chow
Wind turbines are found on land and sea, but now there’s a new
type on the horizon that can tap energy thousands of feet in the
air.
As the video below explains, the helium-filled Buoyant Airborne
Turbine (BAT) is capable of producing twice the amount of energy
of an ordinary turbine because it feeds off the stronger, faster
and more consistent winds of higher altitudes. Cables tethered
to the machine then send the generated wind energy back to a
base station.
Created by MIT startup Altaeros Energies, the tube-shaped BAT
can be inflated, set up within a day and transported anywhere by
a truck, which significantly reduces the installation costs of a
typical tower-mounted wind turbines. This is in sharp contrast
to other land-based turbines, which require giant support
platforms and lots of material, and offshore ones that need a
platform strong enough to withstand punishing ocean waves, which
is tremendously expensive to anchor to the seafloor.
Another potential of the BAT is that it can cheaply and
efficiently power remote and off-grid communities (as well as
areas struck by disaster). As Popular Science reports, one such
off-grid locale has already been piqued by this new technology.
Thanks to a $740,000 grant from the Alaska Energy Authority,
Altaeros will be testing out the first commercial BAT near the
city of Fairbanks starting next year. The 30-kilowatt system is
poised to provide power and even WiFi to a dozen families living
off the power grid. If the 18-month trial is a success, it could
reduce the area’s diesel consumption by 11,000 gallons annually.
It’s a bird! It’s a plane! It’s a wind turbine!

Agelbert NOTE: This technology is aerostat technology. The
technology of mounting heavy machinery on them is is over 30
years old. It has been used for at least that long to mount
radar to catch drug smugglers and other unauthorized flights. It
is robust. The savings on siting and mast infrastructure is
HUGE.
During storm conditions they can be brought near the ground
where they will be more safely tethered while still getting
plenty of wind power during the storm. This is another giant
nail in fossil fuel and nuclear power DIRTY energy's coffin!

Making the Blade Photoessay: How and Where Wind Turbines Get
Their Swoosh
Joan Sullivan, Contributor
October 28, 2014

An industrial wind turbine is a complex machine made up of
hundreds of moving parts, but it takes just three of them to
make the magic possible: the blades.
Wind turbine blades harvest energy from currents of air, but
they don’t come off an assembly line like widgets. Indeed, it’s
difficult to appreciate just how much effort and care goes into
crafting them until you see the process up close.
That’s why I was recently honoured to be the first professional
photographer to lens the shop floor at PowerBlades Industries in
Welland, Ontario. The company is a Canadian subsidiary of German
wind turbine manufacturer Senvion.
PowerBlades opened last year to support the growth in renewable
energy in Ontario spurred in turn by the province’s Green Energy
Act. As of this week, the company will have fabricated 78
fiberglass blades, each 45 meters long and up to three meters
wide, for dozens of 2.05-MW Senvion turbines.
Birth of a Blade
Inside PowerBlades, overhead cranes move girders and blades from
one part of the building to the next. Here, 136 production
workers, machine operators, and office staff work on various
stages of blade production, including lay-up, lamination,
curing, sanding, painting, inspection, repair, finishing,
loading, and transport.
Blades begin their lives in the plant’s Main Shell Area, where
workers lay sheets of fiberglass mat and resin into a pair of
side-by-side proprietary molds each about 50 meters long and
four meters wide. Each blade is built up in two halves, split
down the long axis like a pea pod.
[img width=640
height=480]
HTML http://www.createaforum.com/gallery/renewablerevolution/3-291014195715.png[/img]
Full size pictures at link to 25 page photo essay
Once the resin cures, workers carefully glue the two halves
together. Eight to 10 workers then physically climb into the
blade to scrape out excess glue from the inside. They then apply
heat to finish the curing and gluing process.
Going Over the Wall
Crane operators then gingerly lift the blade to the first of
several finishing stations in a delicate process known as “going
over the wall.” Over the course of several weeks, operators will
lift and shift each blade to a variety of finishing stations for
trimming, laminations, adding minor hardware (such as receptors
and the pointed tip), sanding, painting, and “root end close
out,” which involves installing a plywood attachment that seals
off the base of the blade.
Like sculptors, workers swarm over every inch of the blade with
palm sanders, painstakingly and meticulously smoothing out bumps
and imperfections, before the cranes again hoist the blades to
the painting section.
Buckets and Rollers
The final phase of finishing is refreshingly low-tech — four
painters, two on each side, attack each blade with rollers. Each
takes two coats of paint, about 15-20 gallons in total. On
average, it takes a couple of days for the team to finish its
work.
Gantry operators then lift the finished blades one final time
into shipping crates and convey them out of the building into
the storage yard. From there, Senvion’s clients truck them to
installation sites.
The crew at PowerBlades take great pride in their work, knowing
that they are not only making a good living, but also
slowly-but-surely reducing their province’s dependence on
natural gas and nuclear energy.
“We’re so proud to be working here,” explained Adam Chevalier, a
28-year-old production worker. “To have a job, first. And then
to have a job that is doing something good for the environment,
renewable energy, it’s great!”

Scotland Produced Enough Wind Energy To Power Every Home In
October ;D
According to new numbers published by WWF Scotland this week,
wind turbines generated enough electricity in October to power
3,045,000 homes in the U.K. :o [img width=60

HTML http://us.cdn2.123rf.com/168nwm/lenm/lenm1201/lenm120100200/12107060-illustration-of-a-smiley-giving-a-thumbs-up.jpg[/img]<br
/> — more than enough for all the homes in Scotland.
Referring to it as a “bumper month” for renewable energy, WWF
Scotland’s director Lang Banks said in a statement that “while
nuclear power plants were being forced to shut because of
cracks, Scotland’s wind and sunshine were quietly and cleanly
helping to keep the lights on in homes across the country.”
Based on figures provided by WeatherEnergy, part of the European
EnergizAIR project, the data also showed that for those homes
fitted with solar panels, there was enough sunshine to meet
around 40 percent of the electricity needs of an average home.

Wind energy has been thriving in the U.K. in recent months. In
August the U.K set a new record for wind power generation, with
wind accounting for seventeen percent of national demand. This
came around the time that EDF Energy announced it was
temporarily shutting down four of its U.K. reactors, or around a
quarter of its total nuclear generating capacity, due to
longevity issues. The four EDF reactors under investigation were
commissioned in 1983 and are officially scheduled to be taken
out of service in 2019.

Even for the U.K., Scotland is a green energy leader. As of
September, the country got 29.8 percent of its electricity from
renewables, 34.4 percent from nuclear, and only 34.4 percent
from fossil fuels. Scotland hopes to generate the equivalent of
100 percent of its electricity from renewables by 2020 and to
export non-renewable production
HTML http://www.freesmileys.org/emoticons/emoticon-object-070.gif<br
/>[b]from conventional power plants to countries like England.
[/b]
In the first quarter of this year, Scotland generated a record
6,678 gigawatt-hours of renewable electricity, according to
government figures, an increase of 55.9 percent from a year
before. Wind generation in the first quarter of 2014 was also at
a record high level of 4,214 GWh, up 4 percent year over year.
According to the government, as of March of this year Scotland
had 6.8 gigawatts of installed renewable electricity generation
capacity, with an additional 6.5 gigawatts of capacity either
under construction or consented, the majority of which is
expected to come from onshore wind generation. Including
projects in the planning stages, this figure totals 20.5
gigawatts.
Scotland’s largest wind farm is also the U.K.’s largest.
Whitelee Windfarm near Glasgow has a 539 megawatt capacity, and
generates enough electricity to power just under 300,000 homes.

Energy Storage Will Soon Replace Simple Cycle Combustion Turbine
Peaker Plants 8)
Chet Lyons, Principal, Energy Strategies Group
November 05, 2014
Power grids need extra generating capacity to work properly. For
example, about 20 percent of New York State’s generation fleet
runs less than 250 hours a year. :o Because they don’t run
much, “peaker plants” are by design the cheapest and least
efficient fossil generators. When they do run they cost a lot to
operate and produce more air pollution than other types of
fossil generation. Wouldn’t it be great if we had a
cost-effective and environmentally sustainable substitute for
dirty fossil-based peakers?

/>
As has happened with solar PV, the costs for multi-hour energy
storage are about to undergo a steep decline over the next 2 to
3 years. This cost trend will disrupt the economic rationale for
gas-fired simple cycle combustion turbines (CTs) in favor of
flexible zero emissions energy storage. This will be especially
true for storage assets owned and operated by vertical utilities
and distributed near utility substations.
Simple cycle gas-fired CTs have been a workhorse utility asset
for adding new peaker capacity for decades. But times and
technologies change, and the power grid’s long love affair with
gas-fired CTs is about to be challenged by multi-hour energy
storage. Flow batteries that utilize a liquid electrolyte are
especially cost-effective because the energy they store can be
easily and inexpensively increased just by adding more
electrolyte.
CTs cost from $670 per installed kilowatt to more than twice
that much for CT’s located in urban areas. But the economics of
peaking capacity must also reflect the benefits side of the
cost/benefit equation. Distributed storage assets can deliver
both regional (transmission) and local (distribution) level
energy balancing services using the same storage asset. This
means the locational value and capacity use factor for
distributed storage can be significantly higher compared to CTs
operated on a central station basis.
These points are discussed in Energy Strategies Group’s white
paper, “Guide to Procurement of Flexible Peaking Capacity:
Energy Storage of Combustion Turbines.” As noted in the paper,
Capex for a 4-hour storage peaker is projected to be $1,390 by
2017, or $348 per (installed) kilowatt-hour of capacity.
Factoring in the added value of locating storage on the
distribution grid and ownership and operation by a vertical
utility, 4-hour energy storage will win over CTs at the high end
of the CT cost range by 2017. [img width=70

By 2018 the cost of ViZn Energy’s 4-hour storage solution, which
was selected by Energy Strategies Group as a proxy for the
lowest cost multi-hour storage solutions currently being
commercialized, is projected to be $974 per kW, nearly identical
to that of a conventional simple cycle peaker. For a 4-hour
storage resource – that translates to $244 per (installed)
kilowatt-hour of capacity. Given the added benefits of
installing storage in the distribution network, by 2018 storage
will be a winner against the mid-range cost for a simple cycle
CT and clearly disruptive compared to higher cost simple cycle
CTs.
The disruptive potential of energy storage as a substitute for
simple cycle CTs has been recognized. For example, Arizona
Public Service (APS) and the Residential Utility Consumer Office
(RUCO) recently filed a proposed settlement which, if approved,
would require that at least 10% of any new peaker capacity now
being planned as simple cycle combustion turbines would instead
need to be energy storage — as long as the storage meets the
cost effectiveness and reliability criteria of any CTs being
proposed.
When selecting new peaking capacity, utility planners can choose
between assets that better fit the emerging distributed grid
architecture or the older and disappearing centralized approach
to grid design. The choices we make today should be consistent
with current and long-term cost-performance trends in
fossil-based generation, solar PV and energy storage.
Lower cost solar PV and its rising penetration in all market
segments will have a profoundly disruptive effect on utility
operations and the utility cost-of-service business model. This
has already started to happen. Storage offers a way for
utilities to replace lost revenues premised on margins from
kilowatt-hour energy sales by placing energy storage into the
rate based and earning low-risk regulated returns
