Helen CzerskiIt’s a windy day and just look at the UK’s electricity mix: 70% renewables and only 8% fossil fuels. And those numbers are only going to improve with time. Hooray! #energy #climate #renewables
KeithC@helenczerski what's the other 10%?
Richard R LeeHowever, #NuclearEnergy is just as BAD as #FossilFuels. The #UK could easily replace it with #OceanEnergy (#Tidal & #Wave) it its government was not in the back pocket of #NuclearGrifters and #CarbonGrifters. #Decarbonization #AtScale. @helenczerski
@InfoMgmtExec Tidal and wave energy are not simple (not least in terms of their effect on the ocean and the complexity of maintaining them). The ocean isn’t just “empty” space - it’s an engine doing things that benefit us. We can’t “just” fill it with things without consequences. So for most places, tidal & wave energy aren’t the best options.
Wow! I don't know whether to categorize your response as simply wrong or totally devoid of #facts - #evidence. Your argument is akin to that of accusing #Wind & #Solar as being damaging to the Atmosphere and the Sun, much less hard to build and maintain. There are ONLY three sources of #RenewableEnergy available which do not make the #atmospheric CO2 - #environmental catastrophes that we have far worse. We simply must focus only on them is the point I was making. @helenczerski
quixote@InfoMgmtExec @helenczerski Nukes are at least as bad as CO2 fuels. Agreed. That's not really the topic of Czerski's point, though, is it? She's talking about renewables, as are you. Given how little nukes contribute (and at what cost over their lifetime!), and given UK tides, of course one could make good use of tidal energy. I don't see her arguing with that. Only saying that people are always capable of going too far and having unintended consequences. Which is also true 😟 .
@quixote @InfoMgmtExec Of course I want a transition to 100% renewables as quickly as possible. What I was saying (as an experienced ocean scientist) is that we can’t just assume that expanding into the ocean is easy, appropriate or the best option. There are other options which are far more practical and will have far wider applicability in the short term.
Richard Knott@helenczerski hi
Found an app called Electricity Maps that shows the mix round the world, if it’s of interest:
Electricity Maps
Electricity Maps is a live visualization tool that shows where your electricity comes from and how much CO2 was emitted to produce it. The app displays power production breakdowns, carbon intensity of electricity, total emissions, and electricity exchanges for over 200 regions worldwide. Intereste…
Globob@helenczerski Yes, but. From a climate perspective renewables have to drive fossil generation to zero repeatedly (ie. exceed demand) before it makes sense to add grid storage or substantial BEV / green hydrogen loads onto the grid. Anything else and all we will be doing is shifting carbon emissions around. This is the challenge everywhere.
hodgepig@helenczerski If only our bills reflected that instead of being tied to gas prices.☹️
