What an amazing few weeks for #Nuclear Power. First, DOE launched the #NuclearLiftoff Report. Sober, well reviewed and realistic:…
The Pathways to Commercial Liftoff: Advanced Nuclear report found that the U.S. will need between 550-770 GW of additional clean, firm power to complement the deployment of variable renewables in order reach net-zero by 2050.
All #CleanFirm resources come with Pluses and minuses that we try to define for the first time. Please give us feedback!

My contribution to the #electricity market debate, today at @voxeu
Thread 🧵…
1/Von der Leyen “Current electricity market design is not doing justice to consumers They should reap the benefits of lowcost renewables We will do a deep and comprehensive reform of electricity markets”…
Which should be the building blocks of the reform?
2/ On the objectives:
➡️*Productive efficiency*: demand must be met by the plants with the lowest marginal costs 📉📈
➡️*Investment efficiency*: investments must take place at the right scale, mix, and locations 🌞🍃
➡️*Equity*: prices should be cost-reflective 🪙

Was curious whether #hydro power in Europe will make a comeback in 2023 (after a bad 2022), so I wrote a little explainer.…
European #water reservoir levels in 2022 were very low. They are slowly recovering, in part because policy forced a refill. ImageImage
The shortfall of #hydro power is remarkable, 112 TWh less to date in 2022 than in 2021. And this is largely a flexible source of generation that often drives out marginal plants like #gas. Image

#Manitoba #Canada has an abundance of clean renewable hydro from its 15 hydroelectric generation stations.

This province is great for #Bitcoin and #cryptocurrency Mining.

Here's why hydropower #Bitcoin mining worked great together.

1 / 6 Hydropower is renewable.

Each year, rain and snow replenish the water supply adding to the potential energy reserves of downstream generators.

#hydro + #energy⚡ + #Bitcoin
Hydropower is efficient.

Hydropower dams convert about 90% of the energy in falling water into electrical #energy

By comparison, fossil-fueled plants lose more than half of the energy content of their fuel as waste heat and gases.

Getting the whole world to #netzero #GHGs rapidly is going to be incredibly difficult. But given how strong and organized the #climateopposition is, we must distinguish #thesignalfromthenoise on which pathways are the most likely to succeed. A 🧵 on how I think about this 1/14
2/ First, we cannot rely on social and lifestyle change governed by new paradigms like degrowth to deliver in time for this #climatedecade. But if the movement delivers small reductions in energy or meat consumption, we need it…
3/ #Technologyandpolicy (and politics) need to do the heavy lifting. Can they deliver? Yes, but to effectively channel our efforts and fight off the opposition, we need to distinguish between main courses, side dishes and poison pills (frequently buried in the side dishes)

With the #SofiaDeclaration, the 6 #WesternBalkans countries have committed to #climateneutrality in 2050. To achieve this, a #lignite phase-out for power production is needed, ideally by 2040. To support the debate, we have developed 6 pathways (THREAD). #EUGreenDeal 1/12 The Future of Lignite in the Western Balkans
Where do we stand today? WB-6 power markets consist almost exclusively of two generation technologies: #lignite and #hydro. The share of either source varies considerably between the countries. 2/12 The Future of Lignite in the Western Balkans
Finding 1: 90 % of #lignite power plants in the #westernbalkans was put into operation 30 or more years ago. 40 % of the capacities are older than 40 years. The power plant park is in urgent need of #modernisation. 3/12

As federal action on climate change is deadlocked, again, states have moved ahead.

Still, major obstruction efforts slow, stop, or even reverse progress.

Just up @ERSS: who’s working to slow #climate legislation in MA? w/lessons for other states /1…
Open access! Here's a thread with some key findings. /2
First, states are remarkable venues for social science of #climate struggles: 50 contexts, with different dependencies on #fossilfuel extraction, #vulnerability, and cultural/political context. Industries and activists battle on 50 different stages with different rules. (RPSs)/3

Bonjour Charles Thimon !
Votre documentaire sur l’#Eolien est intéressant mais légèrement à charge 😉
Même si nous avons tous le droit d'être #Pour ou #Contre les #renouvelables, nous devons baser le débat sur des données objectives, non ?
#Thread ⬇️⬇️
➡️ Les énergies renouvelables coûtent chères ?
Dans le 🌍, le coût de l'#Eolien terrestre a baissé de 40% en 10 ans ! Et l’#EolienEnMer ? Le dernier projet attribué au large de @Dunkerque l’a été à ➖ de 50€/Mwh (à quasi égalité avec le nucléaire ⚡️!)
➡️ Les riverains n'aiment pas les #éoliennes ?
C'est plutôt une affaire de goût !
Mais selon une étude @harrisint_fr :
✅76% des 🇫🇷 ont une perception positive de l'#Eolien
✅85% des riverains déclarent que l'#Eolien n'est pas une mauvaise chose 😉…

"For the EU hydro is projected to increase with global warming and nuclear to decrease...increased #hydro in northern Europe and a decline in hydropower and #nuclear power in southern Europe due to lower water availability for direct production and cooling of river-based plants..
"In northern Europe substitution effects, i.e. increasing availability of cheaper #hydropower, could result in lower production costs, while they would increase in southern Europe."
"#Wind and #solar production are not affected significantly by global warming. Improved cooling technologies have the potential to strongly reduce the negative effects of water scarcity, particularly for nuclear plants in southern Europe."

A relative of mine came to me to look for best #FixedDeposit option available today, and that got me thinking that there should be a #Stock which can fulfill this purpose, and voila i got 1 #SJVN, so here is a thread, why at current levels it is a FD.
#SJVN is the principal business activity #Electricity #generation of the company. The company is also engaged in the business of providing consultancy. Both of these segments are not affected due to #COVID19
SJVN Ltd. been honored with the CBIP Award-2020 of Best Performing #Hydro #Power Company. Company has 5 working projects. 2 #Hydro, 2 #Wind and 1 #Solar. Capacities & Locations are mentioned below: Image

Not sure how on the radar this is for you but the #Chinaflooding season starts in 13 days and it’s already a catastrophe.

An interesting analysis of the situation.

#msm not covering this.

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/n A little thread on the impact of #9baje9minute on the Indian #Electricity #grid @PosocoIndia @MinOfPower

From @PosocoIndia o data #India's #power #demand at 19:00 hours in the last three #Sundays:

29 March: 110632 Gigawatts (GW)
22 March: 125000 GW
15 March: 144258 GW
2/n #Power #demand at 19:00 hours on similar Sundays last year:
31 March 2019: 149361
07 April 2019: 150735

#lockdown has reduced demand by 35-40 GW primarily as a result of the partial closure of industries and commercial establishments
3/n In 2019, #residential #demand was about 25% of total demand but it likely to be 33% of the total demand today. So, a sudden change in #residential #demand is likely to have a bigger impact.

This dam conference on hydro-impacted communities starts today! It's actually named "Ki Ta Ski Naw" or 'rise up' in Cree. For those interested in following along, I think hashtags will be #hydroimpacted #hydrojustice & I'll also try to use #SiteC #bcpoli…
Looking forward to the first panel which will be moderated by BC journalist @sarahcox_bc. Opening welcome now. Starting to regain feeling in my face from the walk here, hi Winnipeg!
We're in Treaty 1 territory for the #hydroimpacted conference. Welcome by local elder Dave Scott in Cree language. Speaking now about the treaty relationship, its history, the 'doctine of discovery', Trudeau's White Paper & ongoing devolution process.. cc #SiteC #treaty8

We cannot call it #India-#Bangladesh prime ministerial meeting in true sense of the term, since #SheikhHasina came to the WEF meeting. The bilateral visit is scheduled later. However despite its limited scope I find the meeting very encouraging and beneficial for either side. 1/n
Key takeaways from #Modi-#SheikhHasina
Meeting 1) The LPG deal is consequent to #India's decision to invest in LPG terminal in #Chittagong. With time we wil see rise in supplies and #Bangladesh-#NorthEast LPG pipeline. 2/n
LPG deal is a mirror of #India-Bangladesh #diesel pipeline with the exception that in the case of #LPG, #Bangladesh is also getting #FDI. This is early stages of creation of a regional oil & gas grid, which may be expanded to #CLMV #Asean in the days to come. #Modi- #Hasina

La production d’électricité en #Chine au mois de juin :

#Fossiles : 405.2 TWh (+0.1% sur un an)
#Hydro : 113.6 TWh (+6.9%)
#Nucléaire : 28.0 TWh (+17.8%)
#Éolien : 26.3 TWh (+11.9%)
#Solaire : 10.3 TWh (+7.4%)

Total : 583.4 TWh (+2.8%)

Source :…
Mois intéressant car il illustre un scénario de "pic fossile" : même avec une hausse de la demande en électricité ramenée autour de 2-3% par an, une croissance à deux chiffres des renouvelables et du nucléaire reste nécessaire pour stabiliser la production fossile chinoise.
Question à 10 gigatonnes de CO2 : la Chine peut-elle voir son économie ralentir et en même temps poursuivre ses investissements pharaoniques dans les énergies décarbonées ?
