The new Department for Energy Security and Net Zero - what should they prioritise?

One piece of action for me would be to “join the dots” on renewables. We have a fair amount of wind generation but nothing to use any excess - apart from exports via the continental links. I am also awaiting a place on the next community wind farm via Ripple which will supplement my solar feeds (hope OVO take up this as a supplier hint hint), so onshore wind farms in the right places would be good in supporting local communities. 
I’m also hopefully that something will be done on tidal sources. I see some comments on a River Severn project which can add into the mix. Together these sources can provide so much more for local consumption if put together with some storage solutions.

On the insulation front there have been some efforts on EPC use (what gets measured can be improved) but this seems quite random at the minute. Many of the improvement schemes seem to run out before those in most need take them up - Green Deal, Solar Support etc , probably because they are not well targeted to begin with. They also seem to attract businesses wanting to make more money by providing a less than ideal service. 
All in all, this new department could be useful but I’m not holding my breath

@BPLightlog  We do have energy storage connected to the grid, to soak up spare renewable electricity. We've had a large pump storage station in Wales for many years and we have several battery storage stations across the country, with more being built and planned.

I was in Taunton a few weeks back, and was walking along the River Tone. There’s a weir there called the “Firepool Weir”. 

I thought to myself, why isn’t there some kind of turbine on that weir, and all weirs like it. A constant source of energy in the middle of a town… 

Is it the impact to wildlife like fish?  

There were plans for something like this in Abingdon, near Oxford. It didn't go ahead because the construction costs were too high.

There's another scheme in Caversham, near Reading, that did go ahead. It can generate 46kW. While the output will be fairly consistent, assuming the river level remains high enough, it's expensive compared to solar panels. It cost £1.2 million.

We have the largest battery site in Europe

EDF trade their energy

As well as this, we have an increasing number of domestic households with battery storage. 

For a long time we have had some heavy industry shifting their energy use depending on the availability of cheap energy through the day.

There is lots of great work going on, of course it could be quicker and in some cases better joined up, we don't have an even spread of renewables across the country which isn't ideal.
