We are facing one more #cyclone today. So let me remind you. #Mangroves;

- acts as buffer & reduce impact of cyclones & #storm surge.
- they break the #wind force
- provide #habitat to #animals during cyclone or otherwise
- they reduce #pollution.

We just need to protect them.
So how it works. Mangroves create a maze & dense habitat. With species which are salt tolerant & special adaptations. They act like buffer & consume the winds & energy. So after passing the storms get dampen. You must have read in ‘Theory of Vibration’.
They are prop roots. In #mangrove #ecosystem they are adventitious support roots. They Grow down from lateral branches, in a way support trees, with doing other root functions. Additionally roots buffer against damage to coasts & enhance biodiversity & carbon sequestration.

Offtake risk has become a blanket term that scares investors away from #power sector projects in India. We break it down to understand why that is? 1/n
Offtake risk is the risk posed by the off-taker (also called credit risk, counterparty risk or risk on receivables). In India, the counterparty is almost always a discom or a central government offtaker (SECI/NTPC) buying on behalf of the discoms. 2/n
The power purchase agreement (PPA) is the contract between the power generator and the purchaser (discom/SECI/etc) For RE the PPA mandates that all power generated must be purchased/paid for as per the must run clause. Exceptions are allowed only if there is technical trouble 3/n

1/ Part 1 of my reflections on the Michael Moore-backed #PlanetoftheHumans 🍿🍿🍿
2/ The YouTube write-up is an accurate summary of the movie's argument.
The misanthropy inherent in the phrase "out-of-control human presence" is ... revealing. 🤦‍♂️ Image
3/ This movie will split the environmental movement between the (hardline, blue collar) "degrowth" and (moderate, white collar) "green growth" factions.
It's a proxy for class politics, Gaia-style!

Most of the activist sphere went crazy with an anti-RNG and anti-gas rage that was document in a "not his best day" listening to the @sunrisemvmt piece by @drvox here: vox.com/energy-and-env…
Good thing is that @drvox redeemed himself with this piece today which I found informative and more accurate: vox.com/energy-and-env…

Great event and panel put together by @livemint @UtpalBhaskar converging diverse views from financing, #fossilfuel generation, #energytransition #technology and business operations in the #electricity value-chain! 1/n
As Power Minsiter @RajKSinghIndia rightly said, problems of capacity and #energyaccess has been solved, and the next problem to be solved is reducing #India's #carbonfootprint - #electrification of #mobility and #cooking is one pathway.
Increasing domestic and international demand for #electricity will lead to more #RenewableEnergy capacity installation; new connections and usage will ⬆️domestic demand, integration & #export (neighbors inc #Myanmar #SriLanka) will ⬆️cross-border demand, which India can supply.

We keep having this fight because the last time we had a macro economic frame in this country was Clinton/Rubin which was about the govt not competing in the debt markets
While @SenSanders has Modern Monetary Theory and @ewarren has a wealth tax, neither has wrapped it up into a neat bow for the monied class — they don’t think they have to
So come up with a new frame and call it something like it #ClimateWealth

Happy #NewYearsEve everybody! 2019 has been a record breaking year for GB electricity. Here's why...1/5

✅ Record levels of #solar power 🌞

9550MW on May 14th - the equivalent of approx 1.9 million 5W LED light bulbs 💡💡💡💡
2/5 ✅ Record #wind power 💨 - 16873MW on Dec 10th at the tail end of #stormatiyah

Wind supplied almost 44% of #electricity over the day as a whole.
3/5 ✅ Record number of #coal free days 🔥 - the longest period without burning coal to produce electricity since the Industrial Revolution! @PastCoal

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…

WIND THREAD

1)
Interest in the #solar thread was so strong that I decided to pull together some info on #wind as well. And actually use some #hashtags to make it easier to search.
So with that, on with some windy thoughts from a this particular blowhard:
2)
Like #solar, #wind power faces intermittency problems, so it MUST be paired w conventional power generation unless u r ok having your electricity supply die with the wind. This is particularly the case w old-style 40m turbines in many early-adopter locations like #PalmSprings
3)
Wind’s #sitingrestrictions r different from solar. #Turbines CAN b installed above crops.
Wind CANNOT b installed on slopes (winds r 2erratic, so things alternate between no power & snapped towers) nor above 10k feet (thin air = less force on the turbine blades).

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.

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.
