Renewable energy pollutes London but what’s a bit of smog if you’re saving the world?

Managing the global climate is a tough thing. Sacrifices are required.

The last 100 years has been a success story of cleaner air in London. But air pollution is on the rise again. The fear of carbon is partly responsible for over a million people returning to burning “renewable wood” instead of clean gas and turning around a century long trend. Welcome to the “progressive” 21st century. Too bad about about the dusty lungs and razed trees.

As much as a third of small particle pollution is due to wood fires.

Wood-burning stoves are increasingly popular in middle-class homes and hotels, with 1.5 million across Britain and 200,000 sold annually. Old fireplaces have also been opened up in many houses and can cause greater pollution than stoves. Wood burning is most popular in the southeast, where it is done in 16 per cent of households compared with less than 5 per cent in northern England and Scotland.

Between a quarter and a third of all fine particle pollution in London comes from domestic wood burning. During a period of very high air pollution in January, it contributed half the toxic emissions in some areas of the [...]

Some South Australian farmers going fully diesel for electricity

Maybe they’ll get one like this one? Circa 1934.*

Green management of the South Australian grid scores another big success for the environment:

SURGING power prices are pushing South Australian dairy farmers such as James and Robyn Mann to go off-grid.

The Manns’ electricity costs have more than doubled in five years, from about $200,000 per annum to $500,000.

Due to the high prices, the family will this summer switch to diesel power to run their 116-stand rotary dairy and 14 irrigation centre pivots at Wye in the lower south east of South Australia.

The Manns are among Australia’s top 10 dairy producers, in terms of volume, milking up to 2300 cows and producing 19-21 million litres annually.

If only South Australia had more “cheap” solar and wind power, their electricity might be as low cost as the coal-fired Victorians:

Their move comes as South Australia’s dairy lobby has calculated the state’s dairy farmers paid about 40 per cent more for power than their Victorian neighbours last season.

The Mann’s are definitely going diesel this summer, but may set up a mixed solar-diesel-battery plan in the long run:

Taxpayers give $300m to Saudi billionaire for solar plant that makes 2% of old dying coal plant’s power

It will only take 50 plants like this, and $15 billion spare dollars, to replace the Liddell coal station (8,000GWh), now slated for closure in 2022.

$300m handout to Saudi tycoon for solar farm

Australians are set to pay $300 million in subsidies to an outback solar farm owned by a Saudi Arabian billionaire in a new test of the federal government’s looming energy reforms, escalating a dispute over whether to cut the handouts to keep coal-fired power stations alive.

AGL’s controversial Liddell coal power station in the NSW Hunter Valley generates 50 times as much electricity as the Moree solar farm in the state’s north, which stands to gain big subsidies from households from higher electricity bills until 2030…

But we need more chinese-built glass panels that make green weather-controlling electrons.

Lucky solar power is so competitive. Look at the money roll…

The Moree solar farm generates 150,000 megawatt hours of electricity a year, about 0.08 per cent of the 200 terawatt hours produced on the national electricity market every year. The project is forecast to collect about $50m in payments over the next four years and $90m in the following decade under the existing [...]

62% of Australians don’t want to pay even $10 a month for renewables

The Money Question trumps

Three quarters of Australians may believe climate change is real (so the ABC keeps telling us) but only 13% of Australians are willing to pay $1 a day or more to save the world. Anyone can tick the box “Don’t pick on me, I believe in *Climate$%@$#Change*”. But if people believed it was a threat they wouldn’t balk at paying $100 a year, which is what 62% of Australians did in the latest Newspoll.

87% of Australians think a dollar a day is too much. But hey, it’s only the planet at stake.

Most Australians don’t want to pay anything more for renewable power.

The survey is still biased. There was no option to pay “less than zero”. How much are you willing to pay to get rid of renewables?

The sad thing is that most Australian’s don’t realize they’re already paying so much more.

For starters, The Australian calculated that the bill for federal renewable subsidies would be $60 billion by 2030. That’s $2500 per Australian. In a house of four, that’s $10k over 20 years or $200 per year. And that’s only the federal subsidies and schemes, it’s not the state schemes, nor [...]

Australians forced to pay $60b for expensive “green” electricity

The cost of Going Green, The Australian, Cover,  September 1, 2017.

The Australian calculates the total bill will be in the order of $60b for green electricity.

It’s not like we could have done something better with that.

Read it all (if you can), then write to your MP and Senator. Ask why — if they are serious about helping reduce CO2 — we don’t have a USC coal plant like so many other countries, and why we don’t have nuclear power. Then ask why, if they are concerned about the poor, about health, about education, we are wasting $60b dollars to try to change the weather in 2100 that we could be spending on these critical areas right now?

Taxpayers hit with a $60bn power bill

The Australian,  Adam Creighton

Taxpayers will have paid more than $60 billion through federal renewable energy subsidies by 2030, about twice what the crumbling car industry received over 15 years and enough to build about 10 large nuclear reactors.

The government’s large and small-scale renewable energy ­targets, which will compel energy retailers to buy 33 terawatt hours of wind, solar and hydro energy by 2030, will [...]

The backlash against offshore wind, and the big-money, tax dodging backers of Wind.

It’s a very well written article: Bonackers vs. Big Wind by Robert Bryce. h/t Andrew. The good news is that opponents of wind power are having a lot of success onshore. The bad news is that the renewables industry is pushing offshore instead, but fishermen don’t want them either, and families that have been fishing the same areas for 300 years are up in arms.

“The South Fork fishermen are fighting to preserve their access to some of the most productive fisheries in the world.”

Some eye-opening numbers:

Obama set a target of 10GW of offshore wind power by 2020. But right now there is only 30 MW. It’s 9,970MW short. The offshore push is on. To replace a single nuclear generator will take 45 offshore wind plants. Offshore generation costs as much as three times what gas power costs per KWh.

They face big money renewables proponents — not just rich beachfront homeowners, but large corporations who want tax credits worth millions, and groups like Norwegian oil giant Statoil ASA, plus the Sierra Club and Natural Resources Defense Council (NRDC). Governor Andrew Cuomo has a goal of “producing 50 percent of the state’s electricity from renewables by [...]

SA govt to spend $100m on diesel generators (but could have spent $8m keeping coal plant instead)

I’d like to thank South Australia for so selflessly showing the world how well renewables work. (And thank we West Australians for paying for it).

To get ready for the shortfalls next summer, the SA government is said to be ordering in 220MW of diesel generation at an expected cost of $114m.

The government has contracted privately owned South Aust­ralian electricity distribut­ion company SA Power Networks to obtain and install 200 megawatts of back-up generation across the state before summer. But despite promising a “detailed costing” would be provided in last week’s state budget, Treasurer Tom Koutsantonis did not offer any such details.

The opposition said the budget had allocated $114m for operational costs in 2017-18 from the $550m energy plan, “indicating the diesel generators are going to be very expensive”.

This $106m sacrifice is expected to reduce global temperature by 0.000C, but will save the premier from being called a climate denier at dinner parties:

“Eighteen months ago the Tasmanian government spent $64m in leasing, site establishment and operational costs for 220MW of diesel generation for three months when a combination of drought and repairs to the Basslink left it short of electricity,” [...]

Finkel: Turn the whole country into South Australia by 2030 — 42% “renewable”

In one of the most massaged spin-doctor sales messages in Australian history, the Finkel Report is here to “take the politics out” and solve our energy instability and out-of-control prices. But it’s actually an aggressive green-left weather-control program where cost and stability are secondary to the unspoken but main aim which is to slow storms in 2100. If Finkel were really aiming for stability and price control he’d let the free market run, get the government out of our electricity grid and look at the evidence that shows that solar-panels and wind farms don’t, won’t and can’t work as global air-conditioners for us or our grandchildren.

Australians, read this line and weep:

“Modelling for the Review estimates that by 2030, 42 per cent of electricity demand will be met by renewable generation.”

This is where South Australia is currently at, but it has a lifeline to coal power in Victoria whenever it needs it. What happens when the whole National Grid needs a lifeline? Pull out your wallet…

How much does an undersea cable to New Zealand cost? It’s only 2,000km.

For the same price we might be able to afford a new ultra-supercritical coal plant and catch [...]

Another glorious solar scheme fails ignominiously, “fast clouds”, “rusty pipes”, dumb decisions

Another award winning solar project collapses: it was a $105 million dollar scheme. One company, Areva, lost about $50m and so did the taxpayer. Everything went wrong, management, planning, cheap poor quality steel from China, industrial dispute that left 80% of the pipes rusting on a dock. Three thousand solar reflectors are sitting unused in what was a potato paddock in Dalby. Nobody wants to buy them. They’re obviously worthless. CS Energy is state owned power utility, and it spent $50m but pulled to pin to save wasting another $50m.

In 2011 Julia Gillard raved about how it was going to save 35,000 tons of carbon.

“Ms Gillard says the project could be one of many under the new carbon tax scheme.

“With the clean-energy future I want for our nation, I want it to be a norm,” she said.”

Fans of renewables will cite the management problems as the reason for the failure, not some inherent problem with solar. But the “Clean Energy Culture” is the problem  — the same pathetic, uninformed and corrupt decision-making that subsidizes solar so unnecessarily also creates the same dud decisions in management, legal, and industrial relations. The environment [...]

AEMO Report blames renewables: SA Blackout due to lack of “synchronous inertia”

The Final AEMO Report on the big-SA Blackout deals up some hard truths, and contradicts its earlier claim that the “energy mix” didn’t matter. The key theme here is about the system inertia. The Blackout on Sept 28 last year was an accident waiting to happen, and it wasn’t storm damage to lines that caused it.  The blackout would not have happened if wind power had not been so dominant.

The transition to a 35% wind powered system left the SA grid very vulnerable. On Sept 28 last year, the safety settings on wind turbines were overly sensitive and when voltages “bumped” the turbines shut off suddenly, but those shutoffs hit the system too fast, and that caused the interconnector to shut off too, sacrificing SA to protect the rest of the national grid. The settings themselves are not the main issue — because they can be changed to prevent a repeat. It is a fixable problem — what is harder to fix, is the lack of inertia, and the sheer complexity. These are the biggest challenges of any renewables grid. We can fix even those problems, but at what cost in order to change the weather 100 years [...]

Solar Homes use more grid electricity than non-solar homes

There are probably more solar panels in QLD than anywhere else in the world. Back in February last year, the boss of the Queensland state power company announced the awkward result that households with solar panels were using more electricity than those without. Apparently people without solar were turning off the air conditioner because electricity cost too much, but the solar users didn’t have to worry about the cost so much.

Queensland solar homes are using more grid electricity than non-solar, says Energex boss

Feb 2016:  Solar-powered homes in south-east Queensland, which boasts the world’s highest concentration of rooftop panels, have begun consuming on average more electricity from the grid than those without solar, the network operator has found.

Terry Effeney, the chief executive of state-owned power distributor Energex, said the trend – which belied the “green agenda” presumed to drive those customers – was among the challenges facing a region that nevertheless stood the best chance globally of making solar the cornerstone of its electricity network.

From October 2014 in Queensland, the average grid electricity use of solar homes started to exceed the average use of people without solar power and stayed higher for the at least the [...]

SA Blackout: a grid crippled by complexity

South Australia suffered it’s fifth blackout in five months last week. The AEMO report on that incident came out today. There are lots of faults, errors and small problems, and one overriding theme — it’s too complex:

AEMO (Grid market managers) thought they’d have more wind power. It fell to only 2% of “total output.” There was a computer glitch which “load shed” more people than necessary. Oops. SA Power Network apologized today. Demand was higher than expected.  The gas plant generators at Port Lincoln were ““not available due to a communications system problem”. (Whatever that means.) That was 73MW out of action. One turbine at Torrens Gas plant was out for maintenance (120MW gone). Another was running 50MW low because of the heat. (Seriously, these machines operate at hundreds of degrees and work at 35C but not so well at 42C? (Or whatever it was). Color me skeptical. Perhaps some grid engineers can comment and tell us if this is normal?

So in a modern renewable grid we have variations in supply and demand that are of the order of the average grid load and at the whim of The Wind. What could possibly go wrong?

Finally the SA [...]

Rolling blackouts ordered in SA in 40C heat

South Australia, with 40% renewables, is lucky this has been a mild summer.*

Welcome to your load-shedding future:

Rolling blackouts ordered in Adelaide as city swelters

Widespread power blackouts were imposed across Adelaide and parts of South Australia with heatwave conditions forcing authorities to impose load shedding.

About 40,000 properties were without electricity supplies for about 30 minutes because of what SA Power Networks said was a direction by the Australian Energy Market Regulator.  — The Australian

Premier Jay Weatherill blamed the AEMO for not ordering a gas power station to come online.

Electricity prices spiked to $13,440 MWh. Total demand was about 3,000MW. Things are expected to be the same tomorrow.

At 6pm tonight wind power was producing less than 100MW (about 7% of its rated capacity):

Look at the price spike and the forecast for tomorrow:

AEMO, Electricity Prices, Feb 8, 2016

Perhaps with better planning and more money they can reduce the need for planned blackouts — but why bother?I guess they’ll have those gas powered stations running tomorrow.

It has been smack on average at Adelaide Airport at 28.1C for January 2017.

Big win: Turnbull wasted billions, but now backs super critical coal, copies skeptics 5 years later

Back in 2011 Anton Lang, Tony Cox, and I wrote here about why Australia would be better off with super critical hot coal generators (which China already uses, and which even Indonesia will get before us). Not only do we get cheap reliable power, but it would be a better way to reduce our emissions (if we want to pretend to change the weather).

Now, finally, in 2017 Malcolm Turnbull is saying the same thing as the skeptics he mocked years ago. This is how the “climate meme” dies, one unacknowledged step at a time. Gradually all the skeptical positions get picked up, years later and after burning billions at the altar of “climate control”. This is a big win for skeptics, but don’t expect Turnbull or the ABC to be honest enough to say so. This marks a major turning point in the discussion about coal in Australia which has mostly never got past the “coal is dying” and the “stranded assets” inanity which implied that coal has no future and our massive coal reserves were useless instead of being our major export industry.

Last week Tony Abbott, former PM, called for stop to subsidies for wind power – [...]

China has giant unused wind farms — thousands of spinning white elephants

Wind farm in Xinjiang viewed from the Lanxin railway. | Image by “Train to Xinjiang Provnice” (sic)

The command economy strikes again. China is touted as the renewables leader, installing a gobsmacking one third of all the worlds wind towers. But with a recent economic slowdown, when push comes to shove, coal power is used and wind farms are not.

It Can Power a Small Nation. But This Wind Farm in China Is Mostly Idle.

[NY Times] — More than 92,000 wind turbines have been built across the country, capable of generating 145 gigawatts of electricity, nearly double the capacity of wind farms in the United States. One out of every three turbines in the world is now in China, and the government is adding them at a rate of more than one per hour.

But some of its most ambitious wind projects are underused. Many are grappling with a nationwide economic slowdown that has dampened demand for electricity. Others are stymied by persistent favoritism toward the coal industry by local officials and a dearth of transmission lines to carry electricity from rural areas in the north and west to China’s fastest-growing cities.
