Post 3,000 visitors turned out yesterday for the opening evening of the 2025 Cambridge Beer Festival. First cask to sell out was the beer Mangotron from Elusive brewery. First box of cider to sell out was Biddenden's Strong Kentish Cider. We have more of both though! #cbf2025

@draccoops @thatsamoray @L__Bow Additional tariff and any additional regulation does not come for free: ministerial and parliamentary time is always limited. So what other regulation should be dropped or simplified to allow this one to be improved ?

@thatsamoray @L__Bow Yes I guess a special tarriff based on the prior winters use or anticipated/modelled use) where for every kWh less you use per day you get some discount on your elec use. Or something. Plus its only for units that heat. Plus put a meter on the unit to charge for summer use.

So the BUS has prevented me from decarbonising my home: because a more expensive air to water heat pump is cheaper to me than a cheaper air to air install & because we have a new boiler we wont act on our heating right now. A £3500 A2A BUS would totally change that. Just sayin’

The final UK GHG emissions statistics for 1990 to 2023 reveal agriculture accounts for higher percentage of UK emissions than electricity supply.  @tommlancaster, @ECIU_UK said: "Farming is the sector perhaps most exposed to the risks of climate change." eciu.net/media/press-re…

@bariweiss By the way, climate scientists spend a LOT of time thinking about the climate warming impacts of methane v carbon dioxide- huge area - and a lot of thought given to reducing methane levels. TL;DR methane GWP100 is 30 x CO2 but its half life is 12 years v 100’s of years for CO2

@ProfRayWills "no dependence on the density of the fluid through which the wing is flying... the transport cost (energy-per-distance-per-weight, including the vehicle weight) of a hydrofoil is the same as the transport cost of an aeroplane! Namely, roughly 0.4 kWh per ton-km."

The future UK heat pump fleet could have peak demand on a cold day of 60GW!! That’s a big add to peak demand and also a big potential flex asset. * workings 25m homes Average heat load at DoT = 6kW Average CoP at DoT = 2.5 25 x 6 / 2.5 x 10^9 W = 60 GW

Looks like the y-axis of the graph were mislabeled, here is the correct version (note that all the figures in the paper itself are accurate 😉)

People still haven't grasped the implications of batteries this cheap. Very few of the ideas of what batteries can and can't do hold when you adjust the cost slider by an order of magnitude. Even if batteries never got any cheaper than this, the entire global energy system will be unrecognizably transformed.
Jesse Peltan@JessePeltan

Lithium ion batteries are already cheaper than the future price targets of a lot of the alternative chemistries. You don't just have to beat lithium, you have to beat what lithium will be by the time you get up and running. Lithium still has a lot of room to fall. Cells and packs will get cheaper as people build them for longer durations. You don't need as much copper, aluminum, thermal management, etc. when you're not trying to hit high discharge rates.

@philipsargent @pilgrimbeart Not sure about concrete ratios. I imagine there’s a lot of excess in a Dam. I also think it will be more but maybe not orders of magnitude. It probably needs more mass to stay on the seabed than needed for structural strength.
