• Beaver Valley
• Big Brown
• Big Cajun II
• Big Sandy
• Black Dog
• Black River
• Blount St
• Blue Valley
• Brayton Point
• Bremo Bluff
• Bruce Mansfield
• Cane Run

if there’s a prize for culture warriors, i nominate opinionista @parnellpalme, for squeezing “greenies”, “costly renewables”, “nuclear” and “virtue signalling” before she even got to her opening paragraph.
.@parnellpalme notes germany is “expected to fail the majority of its own 2020 energy transition targets” but neglects to say:
• their goals are very ambitious
• they're way ahead of schedule in the electricity sector — the entire focus of her article.
germany hit their "35% renewables by 2020" target *three* years early, and haven't stopped there — they recently bumped up their target to 65% by 2030.
@DoctorKarl there are a couple of external reasons why a solar (or wind) farm might switch off when it otherwise could be generating:
• "constrained off" by the network operator, basically meaning that the wires near the project are at maximum capacity and can't take more, or
@DoctorKarl • or it could be responding to market events — some projects are exposed to the spot market, and some others have a clause where the offtaker requires them to stop generating when prices go negative.
@DoctorKarl "negative prices" exist by design to provide a signal to market participants that there's an imbalance between supply & demand.
when a project switches off it is simply responding to the market signal.
this @OpenNEM chart from SA last week shows almost daily -ve pricing events.
🤓 there's a persistent claim that electricity retailers buy householders' excess solar for nearly nothing and sell it at a huge profit to other customers.
this is (generally) not true. 1/5
these days, in *most* of the country, the solar feed in tariff is determined periodically by an independent third party and is based on a calculation of the value of the electricity in the wholesale market. 2/5
(in victoria there's even a slight premium paid for solar in recognition of the "social cost of carbon" — ie. a slim carbon price.). 3/5
i keep hearing from @dmichie66 and other pessimists that nuclear is the only tech that's ever decarbonised an economy, so i thought i'd take a look at the latest BP data on *energy* sector CO₂ emissions.
since 1994, nuclear states have done well, but not as well as denmark.
in fact, denmark reduced their energy sector emissions 41% in 15 years. france took almost 3 times as long to achieve the same.
(yes, there are many ways of slicing & dicing this data, but let's drop the "nuclear is the only technology that's ever worked" trope — it's 🐴💩.)
some smart alecs have posted tired old charts about relative energy costs in europe.
the first time i met @AngusTaylorMP, atmospheric carbon dioxide concentration was 393.5 ppm and the newly preselected member for hume was at the start of his parliamentary crusade against renewables energy.
(he'd been fighting as a private citizen for years.)
he was routinely addressing anti-wind farm rallies…
so i was nodding the whole way through. aly's take makes sense — but it was missing at least a few points (in no order):
• the impact of clive palmer's massive spend
• shorten's unpopularity
• the new level of dirty tricks
• failure to "sell" a vision for post-coal queensland
…and the deep dissatisfaction that scandal (eg. watergate, paladin), lies (eg. everything on energy), inhumanity (eg. offshore detention) and incompetence (eg. energy and environment ministers) have been rewarded.
i'm compiling a list of big (>$50m) questionable #coalition expenditure. eg:
• $50m cook statue
• $500m war memorial upgrade
• $80m "ghost water"
• $444m GBR foundation
• $423m paladin/manus
• $185m xmas island stunt
• $50m coal2hydorgen
got any more? 🙏
…and if you care to list any big, questionable cuts made since 2013, please list them too.
