    Posted By: Peter_in_HungaryIf people follow the regulations and you don't like the outcome - change the regulations !!

    Take personal responsibility. If you know the regulations are wrong then do what's right anyway. By all means use whatever power you have to get regulations improved (i.e. vote and wait a lot) but don't expect that to be enough or to be the right thing. By all means try to change people's opinions, but in the meantime lead by example.

    Lots of people support the action against climate change / global warming - until it cost them money, then the excuses roll out. Robust legislation and enforcement IMO is the only way out but unfortunately I can't see that happening whilst big business enjoys the lobby power that is evident.


    What needs to happen is for the whole of the first world, as individuals, to wake to and accept the fact that we are and continue to the primary cause of the climate crisis. Weve grown extremely wealthy at the expense of the climate/environment and its pay back time!

    While we're on the subject of silly regulations: 5% VAT on fuel and 20% VAT on insulation!

    OK, you can 0 or 5% VAT on insulation if you jump through the right hoops but that also leads to perverse incentives in some cases.
  1.  
    And electricity consumers have to pay for historic FITs and for carbon pricing, but domestic gas/oil/coal consumers do not.

    To be fair, it would take more than just a 15% reduction in VAT to make most insulation projects economic. Energy prices have swung around by more than that this year, just based on supply/demand.

    I think the personal economics of energy consumption are something we need to get out of our heads. Its our lifestyle thats causing the problem and we need to start paying a fair price for that lifestyle.
  2.  
    Can we be clear about what sort of hydrogen we are talking about.

    Grey hydrogen is that produced by conventional means which is stripping out of the hydrocarbon feedstock. Blue hydrogen is exactly the same process except that the carbon separated is captured and stored (i.e. carbon capture) otherwise the process is the same. Green hydrogen is produced by electrolysis and is dependent on green produced electricity (usually wind) and requires a lot of electricity. The problem is that this can only be effective about 50-60% of the time as otherwise it would be cheaper to use/sell the electricity. So the model for green production would work best when producing using off peak with storage, rather than other times. If you wanted to produce using base load electric then you’d have to pay over the odds and it wouldn’t be viable.
    Didn’t slog through all the pages so apologies if this has already been posted I did see some mention of the cost - the cost angle mainly applies to green hydrogen because of the utilisation / availability of the wind generated supply.
    Cheers all.

    Yes, that's always been mad.

    Interesting that Germany has started an emissions trading system for all fuels used in buildings and for transport (https://www.cleanenergywire.org/factsheets/germanys-planned-carbon-pricing-system-transport-and-buildings), and EU are proposing to do the same.
