Reading through @OtherProfGreen summary of the 9th August #UK event, the similarities to the 25th August 2018 #Australian separation event across the #NEM are very interesting to observe.
Firstly, they are all attributed to lightning strikes.

And although the #UK one was easy to identify, the #QLD one took a bit of forensic investigation as it happened at a time that no weather warnings were out for the area.
Both events attribute an initial loss of generation due to disconnection of #distributed #generation #DG

I will get back to this point later, because it is probably the most interesting aspect of both events!!

1/ Many have reported on the price spike in Texas amid this week’s #heatwave, causing @ERCOT_ISO to issue an emergency alert. Several stories have pointed to the role of wind power in the #ERCOT system. But that’s not the whole story, according to experts I’ve spoken to.
2/ Articles like this one from Bloomberg put the blame on #wind and the diversifying energy mix in Texas, as coal plants close: bloomberg.com/news/articles/…
3/ But #fossilfuels bear as much or more of the blame. Outages at gas-fired power plants have taken nearly 1.5 gigawatts offline in Texas in the last day (900 MW steam).

So you can’t just blame #wind for the fact that @ERCOT_ISO prices are now reaching $9,000 🔥

THREAD: recently @EurostarJustinp and @EurostarGeorge mentioned windspeeds in relation to #OLE design. In response I promised them a thread on #wind.

No sniggering. Yes, you at the back. I saw you. STOP IT

This is that thread.

1/
OLE is exposed to a number of enviro factors, and wind is one that we spend most time worrying about. It's common for industry types to jokingly refer to OLE as "the wind-blown wobbly wire" - and there is some truth in that.

But wind affects a lot more than just the wire...

2/
…but lets deal with the wire first. OLE must be kept within specific horizontal limits relative to the pan - and therefore to the track. Broadly, in the UK, the wire must ALWAYS be within 400mm of the track centreline.

Doesn't sound too hard does it? THINK AGAIN DEAR READER

1) On 25 July, Tribeca's Commodity Trading Specialist Guy Keller gave an excellent presentation outlining their #bullish #Investment case for #Uranium, expecting to increase their exposure to #U3O8 sector over rest of 2019 as #nuclear demand grows... asx.com.au/asxpdf/2019072…
2) Summary: drivers for higher #uranium prices include growing #demand for #nuclear #energy, #China reactor builds, recent #U3O8 supply cuts & long lead times to recover, mines unprofitable without 50% U price rise, inventories down as contracts roll off, 232 uncertainty gone...
3) #Uranium will play an increasingly important role in global supply of clean, stable, #nuclear base-load power generation given today's focus on environmental improvement amid rising global demand for #CarbonFree low emissions #electricity...

In April, Alberta, Canada, will elect a new provincial government. Many may be unaware that the current @rachelnotley govt has adopted a globally significant #climate plan. Here is what's in it, what it has done, and what is at stake next month. A THREAD #abvote 1/24
First, where did Alberta’s Climate Leadership Plan plan come from? (George Soros, perhaps? Foreign-funded radicals?) No. It came from Albertans. A volunteer panel led by @andrew_leach spoke w 1K residents in-person and heard from 25K+ online. 2/24
The panel also engaged with 350+ stakeholders and met w Aboriginal Peoples in three cities, and received hundreds of detailed submissions from NGOs, industry groups and others. 3/24

According to @ramez good climate policy has 3 key traits:
1. It has a large, meaningful impact on climate change.
2. It tackles the problems that aren’t being tackled by the market.
3. It actually gets passed into law
Aka practical and popular The #GreenNewDeal can be this. 1/2
Technology neutral policies for #climate action aren't what we need!
We have affordable #wind & #solar because policy makers in Germany, and the US, and China created markets for solar and wind before they were cost-competitive. techcrunch.com/2019/02/15/how… #auspol @the_AEMC
Hey @OBenPotter @angelamacd what would it take for you or someone at the AFR to suggest that maybe technology neutrality is not what is needed on #climate? That commercialising techs that can lower emissions around the world is a proven way to go?

I thought it worth a thread suggesting something material might just have changed in Australia's #1 thermal #coal export destination - Japan 🇯🇵. We at IEEFA have written about this quite a bit, but mainly about the growing momentum to exit #coal. ieefa.org/ieefa-japan-ea…
On the other side, @JoshSHill wrote about TEPCO, Japan's biggest thermal power generation firm. They just announced a joint venture MoU with @Orsted for offshore #wind.
Anyone else seeing a Japanese corporate pivot towards #RenewableEnergy internationally?
reneweconomy.com.au/japan-looks-to…
TEPCO also this week announced it will co-seed CleanGrid Partners' US$60m #solar infrastructure fund for South East Asia, starting with distributed, off grid solar replacing imported diesel applications in Philippines. A smallish step, but a good one. ✔️ straitstimes.com/business/compa…

France presented today its #energy and #climate strategy. It has four goals:
1 - To cut #energy consumption
2 - To turn away from #fossilfuels
3 - To diversify its #energy mix
4 - To keep things affordable, increase jobs and innovate medias.businessimmo.com/default/0002/3…
The overall target of France's strategy for #energy and #climate is to achieve carbon neutrality by 2050 through cutting GHG emissions down significantly and also increasing carbon sinks
France wants to cut #CO2 emissions down to 227 Mt in 10 years by cutting final #energy consumption 14% and primary #energy from #fossilfuels by 35%. Also, increasing #renewable heating and doubling the #electricity from renewables. Note: transport emissions vanish by 2050.

ICYMI: A big week for #GreenBonds & climate finance, with the #SR15 reminding us of the urgency to scale up green investment. In this string we’ll point to some of the events & moments from around the world that we’ve captured since Monday.
ICYMI: India: Giant state bank #SBI made a US$650m splash in the #greenbonds pool with inaugural issuance, funding #wind & #solar. In our special Post we profiled the bond, @SGX listing, asked when are more of global Top 100 Banks going to issue green. climatebonds.net/2018/10/sbi-ma…
Still in India: our CEO @seankidney takes some time out for longer form interview with Priya Sreenivasan from @down2earthindia. Shares his [forthright] views on the $US7billion domestic #greenbonds market & its outlook. Worth the read. downtoearth.org.in/interviews/-th…

750 megawatt zoeken voor het #afschakelplan, 5 gigawatt importeren. Grote getallen, maar wat betekenen ze juist? Waarom staat de energie-afrekening in kilowattuur en waarom stoppen we geen zonnestroom in #batterijen? En wat met #kernenergie? Een ⚡elektrisch ⚡draadje!
De watt is de eenheid van vermogen, en is gelijk aan de energie (Joule) die per tijdseenheid (seconde) geleverd wordt. Een waterkoker van “1000W” zet dus elke seconde 1000J elektrische energie om in warmte. Na één minuut is dus 1000W x 60s = 60.000 Joule aan warmte geleverd.
Op een heel jaar tijd komt een gemiddeld gezin aan een verbruik van 12 miljard Joule. Beetje onhandig groot getal, daarom gebruiken we de kWh, of de kilowattuur. Dit is de energie die overkomt met een vermogen van 1 kilowatt, dat gedurende 1 uur geleverd wordt.

With legislation committing California to 100% carbon-free electricity sitting on Gov. Brown’s desk, I wanted to share a timely new peer-reviewed article out today in the journal, @Joule_CP: cell.com/joule/fulltext…
In the paper, @nsepulvedam, @FdeSisternes, Prof. Richard Lester and I use detailed power system modeling to identify strategies that lower the costs and increase the odds of reaching a zero-carbon electricity grid. Check out MIT News coverage of the paper: technologyreview.com/s/611987/how-c…
After ~1,000 cases covering possible future tech cost, regional diffs in renewables quality & demand, and different limits on CO2, our study consistently demonstrates the best way to zero out electricity emissions is to deploy a balanced mix of low-carbon electricity sources.

Reminder: While U.S. is arresting adults and abusing kids from Central America, China is pledging to invest $38 Billion to rebuild SA power grid, incl new #solar, #wind generation - goo.gl/uTx2VV #climatechange
Money quote: "We can install a (transmission line) that can send (#solar and #wind power) where it needs to go. We could even send it all the way to the U.S." goo.gl/uTx2VV - #renewables

Thread) Well there you go: the Minerals Council of Australia rep #BHP, #RioTinto & #Glencore couldn't resist responding to the Kerry Schott's comments that the push for new #coal plants in Australia doesn't stack up financially #lignite #auspol
2) On an earlier thread I thought the MCA would duck for now & respond in the future - but the #coal lobby in Australia are getting desperate & can see how fast the case for new coal globally is collapsing. Desperate times breed desperate PR #auspol
3) There’s a few things worth noting about their latest media release – the MCA have opted to focus their criticism on Kerry Schott

I was about to head offline for 2 weeks, but I need to respond to this new paper from @ppchef before I go on whether #nuclear can operate flexibly. By coincidence, I just had a peer-reviewed article on this very subject accepted by Applied Energy by today! So here's a thread...
In this new "discussion paper," energy journalist @PPchef takes great pains to demonstrate that nuclear power is too inflexible to pair well with wind & solar in a "decarbonized energy system" & thus must be discarded "to make room" for more #wind & #solar publications.iass-potsdam.de/pubman/item/es…
I'm going to defer technical discussion of whether nuclear plants (old and new) can ramp or change output to match fluctuations in net demand and contribute to system reliability/flexibility until my paper is released (short answer: they certainly can if doing so is valuable)...

As clean renewable energy continues to grow at an unprecedented pace, the highest emitting countries are driving toward their #ParisAgreement commitments. In 2017, more than half of new electricity capacity in each of the top 4 carbon emitters came from #wind & #solar.
In China (28% of global emissions), wind + solar = 55% of new electricity capacity in 2017, according to @rhodium_group: bit.ly/2rOuD2K
In the United States (15% of global emissions), wind + solar = 62% of new electricity capacity in 2017, according to @BCSECleanEnergy & @BloombergNEF: bit.ly/235kHtT

Six #nuclear reactors closed since 2013. By my count, up to 23 more reactors may retire w/o policy or market conditions improving: 21.6 GW = ~1/5th of US fleet, 4% of US #electricity--and crucially, 12% of emissions-free generation.

So what's killing nuclear power in the U.S.?
In a new @MIT CEEPR paper -- 1 part #energy #economics & 1 part film noir murder mystery! -- I provide the 1st empirical estimates of what's driving down #electricity market prices & killing profitability of 19 #nuclear power plants across @pjminterconnect ceepr.mit.edu/publications/w…
