Turnbull’s “game changer” — $2 a week savings next decade that most Australian don’t believe

Turnbull threw away the Lib’s best election strategy in the last election and almost lost. He couldn’t run a carbon tax scare like Abbott had (or Trump did even moreso). Now he can’t run a cheap electricity campaign in a nation where wallets are bleeding from power bills. It would be a gift campaign to mock the idea that wind and solar make prices cheaper — that’s a bubble desperate to be popped. But Malcolm’s campaign (if he survives that long) is a Santa tricky plan to have it all — lower emissions, lower prices, and more stability. And if you’ll believe that…

He’s leaving his entire right flank open, unguarded.

A few dismal facts that won’t go away: Malcolm’s NEG plan to reduce electricity prices aims pathetically low ($2 a week) and will fail anyway. The country already knows that. The world still awaits the glorious discovery of a single nation powered by lots of wind and solar that has cheap electricity. Australia’s 1.5% of global carbon emissions are irrelevant. Australia may be the only nation on Earth that is even trying to meet the Paris accord. More than half of Australians don’t buy the blame for the climate. Who [...]

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 [...]

Rooftop solar destroying baseload profitability and proud of it

What other heavily subsidized industry brags about its ability to provide a product for one quarter of the time it’s needed? Vale sunny-day-solar!

Pick a day, an hour, and what are the chances solar will be there for you? A lot less than one in four, because last Monday’s peak in South Australia was an all time record. Every day in the last year was worse.

And so much for cheap… the price when solar power peaked was still close to $50/MWh. Compare that to most of the years of the national electricity market operating when average prices were $30/Mwh.

The price dip at 6am (the black-line bottomless gully), has nothing to do with solar, but was caused by wind power. Far from being useful, essential, or productive, solar and wind power are playing havoc with a normal market, destroying the chance for cheap, reliable energy to find a place. As long as we force the market to accept this non-dispatchable  supply, we are actively punishing reliable power. What investor in reliable energy would look at this and head to South Australia?”

 

Giles Parkinson was excited at Reneweconomy: Rooftop solar provides 48% of South Australia power, pushing grid [...]

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 [...]

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 [...]

Victoria plans to reduce electricity prices by copying state with most expensive supply in the world

In a genius move, Victoria, which has “soaring” electricity prices, now announces plan to copy South Australia where people pay more for electricity than anywhere:

The Andrews government this morning unveiled a new renewable energy target with a commitment to power up to 25 per cent of the state from renewables by 2020 and 40 per cent by 2025.

The government has backed the construction of two large scale solar farms in regional Victoria which will provide another 140MW to the state’s supply, and has set up a reverse energy auction system to bring forward an additional 650MW to the state’s supply.

Meanwhile the trams will run on sunshine.

Legislation creates savings, how?

Victorian households will allegedly each save around $30 annually on power bills under the new plan, while medium sized businesses have been projected to save up to $2400 a year under the legislation which will be introduced to parliament today.

It’s almost like Victoria plans to make electricity from legislation (hey, it’s renewable, and will never run out). By making electricity shockingly expensive, Government ministers can talk of “savings”, even though prices will be far higher than the average price [...]

Australia, Denmark, Germany vie to win Highest Global Electricity Cost! (It’s the Nobel Price Prize?)

It’s not even close: If South Australia seceded it would have the highest electricity price of any nation on Earth.

 Australian Households pay highest power prices in the World, AFR.

South Australian households are paying the highest prices in the world at 47.13¢ per kilowatt hour, more than Germany, Denmark and Italy which heavily tax energy, after the huge increases on July 1, Carbon + Energy Markets’ MarkIntell data service says.

When the eastern states’ National Electricity Market was formed in the late 1990s, Australia had the lowest retail prices in the world along with the United States and Canada, CME director Bruce Mountain said.

 The Markintell report graph:

Hmm — odd coincidence of Price with Wind Energy Penetration:

Wind energy is “free” but countries with the most wind power are also the most likely to get to the top of the Prize Pool for exorbitant electricity. Wind energy penetration is highest in  Denmark (1st), Portugul (8th), Ireland (6th), Spain (11th), Germany (3rd). Conversely, renewable energy penetration is low in places at the tail end of the price curve like Luxemburg 6%, Estonia 15%, Hungary 7%, Lithuania 15.5%. In the low mid price range [...]

SA Solar Thermal plant is a copy of US plant that was out of action for one third of its life so far

Crescent Dunes, Solar Thermal Plant, USA.   | Wikimedia  Author, Amble.

A company called SolarReserve is planning to build the new Aurora 150MW solar thermal plant at Port Augusta, which is apparently a copy of their Crescent Dunes plant in the US. But that project has been offline for most of the time since last October. The whole SA government is meant to be running 24/7 off “solar power”, which allegedly only has about 8 hours of energy stored up (as heat in the molten salt block). So an 8 month break will be a bit of problem for the SA government (except of course, we all know that the real baseload backup here at 4 or 5am everyday, and most of the day in winter, is ultimately the very fossilized gas and coal.) Since the project only began working in Sept 2015 it managed to operate for all of one year and one month before it went offline for 8 months due to a leak. The SA State Energy Minister is not concerned saying it was a construction issue and SolarReserve “have learnt from that”.

The 150MW myth: most of the time it will be less, a lot [...]

Electricity cost train-wreck arrives in Australia

Something very “seismic” has happened to our electricity prices.

Paul McArdle of WattClarity goes through each state looking at quarterly trends and prices, and remarks that things are going “off the chart”. We had some electricity crises in Australia in the last 12 months, and 2016 was a significantly more expensive than all previous years bar the major drought year of 2007. But ominously, prices haven’t come down in what should be a “normal” quarter. In Tasmania there was a crisis last year when dams ran dry, and the undersea Bass cable broke. But this quarter, prices are only $3.20/MWh lower than the crisis levels of Q2 2016 despite water in dams and a working cable to Victoria. Something has gone seriously wrong with our electrical grid and market. In both Victoria and South Australia prices are higher on average than any previous April-June quarter in the 19 year history of the National Electricity Market. In Queensland and New South Wales, prices are at the “second highest”.

McArdle goes to some length to explain that this is not “one factor”, which seems obvious and fair — Its the combination of the closure of Hazelwood and Port Augusta coal generators; the [...]

Wind disappears in South Australia, costing wind-industry millions, BOM blames climate change even though models predicted faster winds

The wind fizzled out over the South East slab of Australia during June. Predictably, that meant the wind industry lost millions, and wholesale electricity prices went up. When the Bureau of Meteorology (BOM) was asked where the wind had gone, Darren Ray, expert climatologist, said it was due to a high pressure system over the bight, which, he explained, was linked to “climate change”. Thus, as the world warms, wind farms will be progressively more useless in South Australia. Perhaps the BOM should have mentioned that before SA became dependent on wind farms? I don’t think he had thought this one through.

Perhaps the BOM is hoping that the masochistic sacrifice of South Australia will stop global warming before global warming stops the wind farms?

You might think that if the global climate models could see this coming they would have suggested that wind farms weren’t a good idea. Or maybe, since climate models predict every equal and opposite outcome in unison, the models are always right post hoc, but not so useful in projections?

Climate models predict climate change causes faster and slower winds over Australia

In 2017, Darren Ray, BOM expert, said the decrease in winds was due [...]
