Want #zeroenergybills? Here's how: you earn £££ exporting solar in the summer, and this is enough to pay for your home & heating in winter, if you use the right tariffs and a highly efficient heat pump. More at netzerohome.uk

Summary of budget measures for home energy, which reduce the elec:gas price ratio a bit, & including the possibility of a further rebalance by shifting the remaining 25%of RO costs onto gas.
We've got some Nesta reaction to the Budget up, underpinned by some brilliant speedy analysis by my colleague Dan Lewis.

Generally good news for net zero energy bill prospects: some policy costs reallocated to (more progressive) general taxation, while the boiler upgrade scheme for heat pumps remains intact.

A package that saved at least £150 off the average household bill was the minimum this Budget needed to achieve to give Labour at least a fighting chance of getting to their £300 target, given the price rises next year. /1

I get annoyed at the narrative that all the awareness and work on climate change hasn't done anything. Yes, global CO₂ emissions indeed continue to climb, but we don't know the counterfactual. When I was in grad school, we were on track for 5°C of warming. Now it's below 3°C. That's progress.

The 2 big rules to keep your house cool in hot weather:
1. As soon as temps outside are higher than inside, close all windows. Shade/curtain all the sunny ones.
2. Then at night, get all the windows you can open, with through draft.

Many just do the calculations based on standard tariffs. But smart elec tariffs can slash running costs compared to gas. We paid 20p/kWh in January, 20% less than price cap.
Take up of heat pumps ‘may be boosted if households shown running cost savings’
UK Finance say many households may switch to heat pumps if they had a better idea of how much money it could save them over the longer-term in running costs.

Frustrating fossil gas sets the UK elec price 98% of the time, while only providing 30% of elec, keeping bills high.
New proposals from Stonehaven could break this link, taking gas power out of the market for strategic control by NESO.

When we were considering a heat pump we did worst case calcs to see what happened if the installation performed poorly.
Concluded that worst case we had same bill as gas.
Reality? We have sCOP of 4.5, off the end of this graph & halving bills.
Big upside, zero downside.
