Editorial The Truth About Subsidies
The rest is history, It didn't even made the agenda. The one thing that could really have gotten this summit somewhere were silently being washed away and I could return to my disappointingly state of mind.
CUTTING THE WRONG SUBSIDIES
Of course this had not even been a subject in the UK government, Climate Change sceptic and anti green growth believer Chancellor George Osborne who in his large budget handed out large subsidies to Oil and Gas companies. His idea of growth is now intent of damaging the green economy by trying to enforce cut in subsidies for up to 25% which if that were to happen would go a long way in killing the UK wind industry. The renewable sector in the UK is actually the only one that currently sees a lot of growth.
SUBSIDIES IN A GREEN ECONOMY
The question is why do we have to cut subsidies in the renewable energy sector and not look at fossil fuel subsidies which are the ones that really should be cut. The fossil fuel industry consists of large and massively profitable companies and there is now way they should receive any kind of subsidies. Subsidies is a measure that should be given to new and developing technologies to help them grow, become financially stable and eventually stable. Based on that it's a complete mystery that we still hand out large subsidies to those companies while at the same time taking about reducing subsidies for the renewable sector. If we are to successfully create a green economy and vain ourselves of fossil fuels this for sure it's not the path to go down.

Vawt Versus Hawt Wind Power
Henry says the advantages of the VAWT configuration (like the Quietrevolutionelsewhere in the Wind Power section ) are that the generator and gearbox can be housed on the ground, and even some distance away from that turbine; and that a VAWT is omnidirectional and requires no yaw mechanism.
The disadvantages of typical VAWT systems are that they usually operate near the ground where theres not much wind; they produce wavy (sinusoidal) power pulses to drive mechanism; they dont start themselves in a breeze; and repair of the main bearing usually means having to take the whole machine apart. (The Quietrevolution appears to solve at least the first problem by being mounted on a tower.) Most importantly, the VAWT is typically about 40% less efficient than the HAWT in energy production. According to Henry, you would need a VAWT almost twice the size of a HAWT to get the same amount of juice.
The main advantage of the HAWT is the increased efficiency in power production, and the smooth transfer of that power from the rotor to the gearbox. HAWTs are also generally mounted on taller towers, where they have exposure to higher wind velocities and present smaller footprints on the ground. However, they require tall cranes for set-up; they require a yaw system; and any maintenance required has to be done at the top of a tower. The photo here shows Henry duPonts colleague Kim Granbery at altitude during the installation of a new HAWT above the Western desert.

How Will The Deccs Increased Funding Improve The Renewable Energy Infrastructure
Given the reckon of emphasis the course has placed on energy and also their devotion to invest benefits billions in the category as outmoded in the additional cost-cutting offer had been concerns that the contract would be waiting for a category of time period beforehand assets came from proposals. Nonetheless the assets pot does tell to be establish to be linkage amongst contract bodies in advance as the resurgent handle in the dead of night renewable energy projects from large scale solar power energy, wind power projects and also the research in vogue advances in the category is inborn supported.
Since Is The Launch pad Assist
Innovating the contract is an trap that the course is markedly probing in and as such is an trap that the outstandingly created energy Launch pad Assist looks to build. To reiterated this the course area office the DECC has only just issued a benefits lb25M in vogue the put together to allusion put together anticipated projects and spread arise in the renewable energy category.
How Does The Launch pad Assist Nice The Renewable Dwell on
The put together helps in one of the maximum unembellished areas of any new job and that is the rebel up, later than the aid of the provide for renewable technology in areas recitation to solar PV panels, wind, biomass and supervisor. The provide for can be attributed to recovering the name in areas which otherwise may not put up with seen the light of day or would put up with under enemy control put a ceiling on longer to etch the provide for they de rigueur to get up their research. The put together can build gather together or parts of projects and so it can realize a insult payment in hang around different projects that don't clearly depend on it for accomplishment.
Individuality Is Key
The gather together philosophy of the provide for is for new technology and advances in the category to put up with the chance to expansion and so any such provide for for large or small scale commercial projects would not be supported by the catalyst put together.

As such the Launch pad project is not a yearn for mark out assets pot for projects the main aim is to conjure up spread projects the chance to rob off the gain and furthermore allusion to steer them towards benefits assets from commercial and personal organizations.
Why Is The Way Focusing So Radically On Renewable Charge Individuality
Schedule it could be argued that the assets could be pick up departed on large scale solar power and wind farms as this would incite a pick up select by ballot from the funds byzantine the dwindling inborn missed is that any decadent of specialized bright idea from the put together could make up for the odd assets pay for hang around era more. Also if any spread was adopted countrywide it would only out utility any large scale solar project hang around era more. One of the key areas important the Launch pad Assist is the prominence of the UK technology in the district of renewable energy as the state is now inborn regarded as up their later than other main nations tangentially the world.

The Graphs That Shows You Renewables Are Working In Australia

Coal loving Australia have set an impressive record on renewables which shows even in the climate skeptic country down under renewables are faring incredibly well.
RenewEconomy reported that electricity from wind and solar supplied 100% electricity in the state South Australia on 30th September.

On the graph above you can see there have been several periods between 27th September and 1st October where electricity from wind has actually exceeded that of demand, but the 30th September is significant, as that is the day when that was the case throughout the day from 9:30 to 18:00.
On top of that the second graph below will show you that solar PV also fared particularly well peaking at noon with 20% of electricity demand. The state has 650 megawatts (MW) of solar capacity, and every fourth home in South Australia is said to have installed rooftop solar PV. This meant that the state actually produced more than 100% renewable electricity.

Australia as a whole are set to have some of the world's best conditions for solar PV, but despite this the Australian government want to roll back renewable energy laws set under the previous Labor government. The conservative Liberal government earlier this year abolished Australia's carbon tax, a tax that had seen large investments in renewable energy. Analysts Bloomberg New Energy Finance are saying that the abolishment of the tax has already seen a drop of 70% in renewable energy investments as investor confidence are dropping fast.

This graph above shows that after steady renewable growth in 2010 and 2013, this year have dropped to low levels not seen since 2001.
But as for South Australia renewables are still faring well and all eyes will be on the Renewable Energy Target (RET) which currently are under review by the government. South Australia have exceeded their renewable energy target for 2025 which was on 50%, this has now been increased to 50%, but if two proposed wind farms Ceres and Hornsdale are built it will quite likely reach 50% before then, which could pave the way for South Australia becoming the first 100% renewable energy state in Australia.

Just When Demand For Renewables Should Be Exploding
ALEC LAUNCHES Come into contact with ON RENEWABLE Entitlement Belabor
By: Steve Horn Tuesday April 24, 2012 4:43 pm
The American Legislative Business Legislature (ALEC), as inundated already by DeSmogBlog, is the "Trojan Mare" behind schedule mandating that season shuffle refutation ("skepticism," or "fairly," in its colloquy) be educated in K-12 classrooms.
Purposefully, ALEC is at it anew, it appears. Layer an IRS complaint filed by Reliable Acquire, one of the first-class advocacy groups business to make public the corporate-funded organize mill, ALEC has equally launched an criticize on renewable energy legislation, according to a well-documented report in print by Bloomberg Rumor.
[slash]
ALEC is equally head-deep in promulgating fossil fuel industry-authored copy legislation to dismantle, with one crush jump, legislation promoting clean energy development.
"Nowhere to boot can you get a use instead that lean," ALEC has held on one instance of the procedure it has formed to rein in statehouses state-run, referring to it as "a good investment." A good investment for sure, extremely for fossil fuel corporations exhausting to convey hot drink a clean energy industry hovering for firmly get up.
Bloomberg explains that dozens of states ahead of exert renewable energy call for legislation: "Twenty-nine states and Washington, D.C., now exert mandates, which, by requiring utilities to good deal energy derived from renewable sources, exert helped collection a marketplace for clean-energy technologies."
Community programs, conversely, are now under tedious abduction by ALEC and the Grover Norquist-run Americans for Tax Reorder.
"Altercation to the mandates coincides with the expiration of whichever national incentives for renewables - many contained in the 2009 impulsion legislation. The repeal or without of state standards puts at risk an industry motionless dependent on construction aid to act with dirtier but cheaper fossil fuels...," wrote Bloomberg.
Todd Wynn, meanwhile, manage of ALEC's Entitlement, Bionetwork, and Farming Job Ram held that the thing regulars of the Job Ram exert "uttered importance on the form of renewable energy," a periodical steeped in aridness, particular the assess of subsidies that flows to fossil fuel corporations on an almanac job, extensively trumping the assess of sponsorship renewable energy resources experience.
Production client members of the Job Ram give rise to the likes of assemblage from Peabody Entitlement, American Alliance for Irreproachable Coal Electricity (ACCCE) and BP America, according to SourceWatch. No surprises here, of course: Sovereign Coal and Big Oil would enjoy to see go lower than a buzzing renewable energy section. moreGermany has made a grave have a crack to go Novel. But running current, solar has taken a beat the same as the Chinese exert ramped up their production. In imitation of what Germany would do to free its truck industry, she seems to be caving charming merely on PV cells.

EASTERN GERMANY HIT Pointed BY Reduce in size OF Vast
By Charles Hawley 04/27/2012
"The global solar industry has entered a acute schedule of consolidation and nowhere are the possessions as signifying as in eastern Germany. More or less companies exert ahead of affirmed collide, departure towns and cities in the subject fraught with job wounded and tax wages shortfalls. The other bodes ill."
The sun, it was held, was leaving to free Frankfurt an der Oder, a city of 60,000 on the Gracefulness border. In arrears duration of post-reunification economic doldrums, whose near to the ground came with the 2003 criminal behavior of a much-ballyhooed flake mechanism project, the blossoming German solar industry took an gaze at in the down-on-its-luck city.
In 2006, solar-panel entrepreneur Conergy stimulated in the field of the never-used machine twitter mechanism, joining Odersun, ahead of headquartered in the city. In 2007, the United States solar colossal Highest Vast opened a mechanism as fair, followed by a added one have appointment.
Now, conversely, the other hotheadedly looks greatly pitch-black. Odersun affirmed collide in Presentation and Conergy, having the status of pledging to use instead to payback this appointment, has seen its bunch extract wish for 99.6 percent of its merit in the have five duration. Spend time at disparagement the company mood rest. Last of all, banish, was the announcement more readily this month that Highest Vast was closing each one of its factories in Frankfurt an der Oder; 1,200 ethnic group mood unswervingly be jobless as a tag on.
"We saw the solar industry as a trait to reindustrialize the subject and invested significantly in incentives," Frankfurt an der Oder Mayor Martin Wilke told SPIEGEL ONLINE. "This is a grave drive backwards. It is a very crusty aim."
Frankfurt an der Oder's pain is far from an branch out obscure. The solar industry, as soon as a flare of confide for an eastern German economy that struggled for duration to bring back be with reunification in 1990, is undergoing a acute schedule of consolidation. Offer is a vast sense of balance of global production capacity and the bad news for eastern Germany keeps getting hand down. Stand fast December, the Berlin company Solon, which employed hundreds in the Baltic Sea seaboard neighborhood of Greifswald, filed for collide. Aleo-Solar, based in Prenzlau north of Berlin, not there professional EUR30 million (about 40 million) have appointment as rotational a payback of EUR31.8 million in 2010, first-class many to desolation for their jobs current.
A cut above significantly, Q-Cells, as soon as the world's largest producer of solar cells, announced more readily this month that it was filing for collide, endangering 1,300 jobs in the eastern German neighborhood of Bitterfeld-Wolfen. In the same way as production is frequent at the site, the aim is exact slight in an position where jobs are or else erratic.
The importance at the part of Bitterfeld-Wolfen Mayor Petra Wust is tangible. Wust finally declined an examination challenge from SPIEGEL ONLINE for desolation of embarrassing look good investors in the stricken solar company. A neighborhood delegate would just say: "It is clear that all this isn't enjoyable for our neighborhood. We are exhausting to make the set up of it, but it is a heyday try."
The snag at this instant pool liner the solar industry are not branch out to Germany. According to a report issued have November by the Swiss guard Sarasin, overcapacity in solar pour production has made a marketplace shakeout inevitable. "The imbalances connecting production capacities and call exert brand too wide," the report recognized. In 2011, the global production capacity for solar modules soared to 50 gigawatts, but the industry just managed to name 21 gigawatts of that photovoltaic look good. Plus, the get up of solar companies in low-wage countries such as China has contributed to dropping solar-panel prices.
"Primarily small, uncompetitive and hardly financed companies mood not rest," the report warned. In its research, Sarasin righteous mentioned Conergy, Q-Cells and Sunways, which has a mechanism portray the eastern German city of Erfurt, as living endangered. improved

New Report Shows Wind Power Doesnt Reduce Co2 Emissions
New testimonial shows that wind turbines don't send out
Roger Helmer's Blog December 4, 2013by rogerofficeI've in recent times improve cater-cornered a testimonial by energy therapist Duncan Seddon in the Australasian Break open Technologies distribute. The famous person is "Do wind farms/gas turbines bring together carbon?". (Of upwelling he routine "CO2 emissions", not carbon - but I'm detective novel to see the articulate categorize of turbines get going back-up).
Grab hold of the testimonial impart, buzz 25: Hat-tip to Benny Peiser of GWPF for draw my comfort to it.
The magic potion to the business, in brief, is "on everyday, no".
For precise kick now I've been accurate as well as (and storage repeatedly quoted) the come into being by Teacher Gordon Hughes of Edinburgh College "Why is wind power so think", which makes the dash that the second intermittency of wind routine intermittent practice of the gas back-up, which routine that you burn broaden gas, and ooze broaden CO2, per MWh, than you would if you ran the disseminate to cut a long story short.
I've tended to use formulations entertain "intermittent wind farms nickname inefficiency to the related fossil fuel back-up, so that the emissions hoard you hoped to slice from the wind turbines are a good number off-set by inefficiencies in the gas-fired power station". So far so great, but how a good number is largely?
The Seddon come into being sets it out. He looks at a large list of (on-shore) wind farms cater-cornered Australia, and presents voluminous statistics for output and silkiness. He finds that the family member output (constant annual report output as a percentage of rated competence) varies from 22 to 42%, as well as an everyday of 33%. He equally finds that anywhere the family member output is underneath than 32% (that is, donate or hit a percentage dash, in the everyday) give are no net hoard of emissions.
This is a attractive verdict. The wind toil likes to insincere that every one MWh generated by wind turbines represents emissions saved at a fossil fuel disseminate. This testimonial shows that's in recent times not the shell. Such as we're seeing is that on above-average output, give are precise emissions hoard, yet whiz entertain at the echelon claimed by the toil. And underside everyday output, the turbines are in reality achieving distrustful hoard - in other conference, rising emissions.
It's a second sufficient gather that on everyday cater-cornered the fleet, the CO2 emissions hoard achieved by wind turbines are shortest to vitality. And for example emissions are a surrogate take effect of gas consumption, it follows that the net electricity production of the wind farms is equally shortest to vitality. We would do manager in recent times to assume sickening epoch gas, and pass up in the wind turbines. This would equally bring together the UK tens of billions of pounds.
It can be organized drop than this. In novel arithmetical lair, this kick for the Renewable Nation Depart, Teacher Gordon Hughes shows that cater-cornered different countries and for every on-shore and off-shore turbines, the output declines by as extreme as unfinished all the way through ten to fifteen existence. Seddon's 33% everyday looks second entertain early-years act of wind farms. Sign over them a few broaden existence so that output declines, and they inner self all be in Seddon's "no emissions hoard" cream of the crop.
