Energy bills.
Basic Eco (costs less at peak times more throughout the day and the night is not at it bottom with smart meter and a smart my ecology phone app)
Here you can get discounts for moving from gas showers to electric showers some of which the shower company pays for, some of which the government pay for in lower vat, some you pay back in your bill and some you can pay back by topping up to the nearest pound on your card purchases and some is saved by making such a move.
You can also get similar type discounts changing from a gas cooker to an energy efficient electric one.
With more upfront cost you can upgrade your heating to electric.

Storage package
If you are in a target home or building you can install a grid batteries and pay less for the smart grid battery by paying off some of the cost in savings and rounding up spends to the nearest pound.
you can also get the basic discount's also in a serial fashion after fully paying for your battery.
There are a few smart home options with this service like home emergency usb ports in power cuts.
If you are in a target building for wind bobbles on rods you may get 15-225w from the wind buzzing around your roof. This could be an extra 0.5 GWe in times of need and more for storage.
Here your costs and savings on this scheme are based on supply demand and primarily excess supply of green energy.
1.4 GWe
grid additional
Along with the rest of the package you may want a smart grid battery for your solar grid array or you might get discounting to actually install solar panels or tiles or you might just want the solar only package.
This all is priced relative to supply and demand.
0.8 GWe

60000 of the biggest gyms wire extra energy into the grid and get slight discounts when fossil fuel use is higher and they are more needed.
0.3GWe

In the worst of times we could do up 8GWe extra with aluminium air stations to be later phased out and replaced by aluminium ion batteries.

coal power might need to go up a little. 1GWe
We might need to share more gas as extra comes in from the north sea.
Amber alerts if gas demands on the grid are up to high. (0.3GWe savings a that moment)
more incentivisation to use public transport.
hybrid bus development to upgrade to full electric by 4 years.
little vat saving for hybrid vehicles.
A full Review of the country's company and public sector logistics to find savings in fuel use.
Slightly backing down from full electric cars until the aluminium ion solution is in full swing. (0.1 GWe instead helping the grid as smart grid batteries).
and have a plan to adapt the economy further once aluminium ion battery cells are in full bloom which should be when inflation fully starts to settle when you consider the energy crises we are in and how key such a viable green grid technology is and how it is key right now to bringing the world to better sense.
It's because if you can store energy cost effectively and green on mass then your cost of sustainable energy drops dramatically far below fossil options due to far less energy waste meaning a brand new non fossil economy that we've never properly been in before equating to probably below 1.5% by 2030 and below 1% by 2040 along with the efficiencies optical computing will offer by 2030 to 2040.
The economy is costing us some serious dosh and quality of life because of the fossil fuel market an issue renewable's are already helping mitigate against.
