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
Ironically, this was precisely the strategy of "Connect the Americas 2022" program launched by Secy State @HillaryClinton under @BarackObama in 2012 - goo.gl/A9htzY - #climatechange #RenewableEnergy
1. Some banks may be re-investing in coal after promising not to do so, as @nytimes reported this week, but that doesn't mean #coal is coming back - not by a long shot. This THREAD explains why:
2. This new @nytimes report by @flitteronfraud shows that some banks are dragging their feet on moving #BeyondCoal even as the industry’s last legs continue to wobble: nyti.ms/2LDELkP
3. More than half of the coal plants in America have retired or committed to retire and, despite the Trump administrations ridiculous ploys, utilities are abandoning coal at roughly the same rate under this administration as they were under Obama: sierraclub.org/press-releases…
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…
