@WelshRugbyUnion I will pay you £5 if you can tell me how to watch the Japan games. I cannot get any clarity of who is showing it on the 5th. Diolch

@dragonsrfc My favourite Cardiff player, thanks for the memories. How he hasn't got more caps is a mystery.

@JomauxJulien Thanks Julien. Solar cannibalising value is still not being appreciated enough in analyses. Still, solar is crazy cheap and getting cheaper, it must power the world. Using tropical solar, Interconnectors to the world, batteries, DSR and maybe some despatchable has to be cheapest.

@cardiffcouncil Please massively grow the car club now. It is the only way you can reduce the need for car ownership whilst allowing people access to travel. In ten years there has been no growth and you are building new developments without car clubs today. @DeAthCardiff @CaroWild Thanks

@s8mb More important for nuclear is how to reduce costs to compete against super cheap solar coming to a cable near you.

@s8mb I think 2030 is not going to happen and is the wrong analysis of the trade-offs between faster decarbonisation and a more cost effective one. We can go nearly 100% wind solar and existing nuclear with interconnectors and DSR/storage. Nuclear can’t change the maths by 2030.

@jessralston2 Solar is default for all new builds in England. (Builders have other options.) The grid can cope fine if we use marketsto encourage flexibility. The reason sooar should be standard is it saves residents a lot of money.

The Coming Solar Eclipse Solar is so cheap, is it inevitable and wonderful the entire world will end up running on solar power connected as a mesh across the world? https://t.co/aQc8hz2PIx via @LinkedIn

[Barny Evans @Evonator]

@janrosenow Yep, we need much more open markets and flexibility. Variable prices reduce costs for individuals and at a system level. Imagine a flat rate for flights or trains. We just need to embrace same system for roads to improve productivity.

[Barny Evans @Evonator]

@cardiffcouncil Hi that is good news. Please can you confirm they will be on roads not pavements?

[Barny Evans @Evonator]

@JomauxJulien Going to be where the solar is cheapest plus allowance for reasonable access to other resources.

[Barny Evans @Evonator]

Please help. Looking at solar prices globally and there are loads of solar deals going at ~£10 per MWh, see below. Before I extrapolate on that, are they missing anything? I don't mean intermittency or balancing, just is the price all in? Thanks

@James_BG @neso_energy Thanks James. That does make it a lot easier. It is still not going to happen, but more importantly no one talks about whether it is right. Faster decarb is good if it affects nothing else, but this pace of change would increase costs and harm economy. Need to balance trade-offs.

@guynewey Sorry, too few letters. Saying we have been told about low regrets before which we have regretted lots - Gas DHNs, hydrogen surface vehicles, etc. 90%+ of solution is electrifying and making elec. cheap.

[Barny Evans @Evonator]

@guynewey Agree on innovation, but must counter idea we need lots of breakthroughs, mainly grind of reducing elec. price & making loads elec. On low regrets, need care: We did gas DHNs on that basis & they now highest CO2 heating. Need elec. infra but need see how far smart takes us 1st.

[Barny Evans @Evonator]

Let's hear it for the much maligned urban heat island.
