Is this the best they've got?

From a recent City AM:

The UK should not leave the EU – the single market has greatly strengthened the British economy. To continue trading so much with the rest of Europe, the UK would still have to follow the rules set to regulate the single market. But from outside the EU, we would have no influence over what rules are set. Much better to be in the club and able to shape their design.(1)

The EU also plays an important role over energy and climate policy, both linked to future economic growth. Europe needs a modernised and extended electricity grid, including a North Sea grid. Building this would enable the UK to harness enormous quantities of offshore wind power, thus increasing UK energy security as the oil and gas runs out.(2) It would be possible if the UK leaves the EU, but easier and more efficient if we remain a member.(3)

Oops, I pressed send too early (I meant to save as draft and finish off once at work). My point was, surely, there must be some advantages to being in the EU which everybody accepts (yes there are: but no clues), not flim-flam like this? Or at least they could stick to the Big Fat Lie that "Three million UK jobs depend on us being in the EU" which isn't true either, but a lot of people seem to believe it.

1) James James had already covered this in the comments by the time I got back.

2) I think we've seen through all this wind nonsense by now, and it's the EU demanding that the UK shuts down its perfectly servicable coal-fired power stations. So energy supply is a bit of a worry. But there are two forces which will hopefully sort all this out.

a) Governments know that they have to make sure that "the lights stay on" and that petrol is always available on the forecourts, because if they don't or it isn't, they'll become very unpopular very quickly (even if there is little they can do about it).

b) Markets. There is a fantastic network of infrastructure spanning the globe, there are oil and gas pipelines linking Russia and Norway (not EU members) with most of Europe; they're laying electricity cables across the North Sea; we buy liquified natural gas from Qatar; the Iranians are quite happy to sell us oil (even though they are not in the EU and their openly stated wish is to attack the West, I wonder what they'll do for customers then?). And these are just a few things off the top of my head, there's plenty more where that came from, fracking near Blackpool, oil rigs in the North Sea, the list goes on.

3) Exactly, that's one heck of an admission. Maybe there is a teeny, tiny slight advantage to EU member states if they can all gang up against e.g. Russia, Middle East and negotiate one big contract, but there are equal and opposite disadvantages (if it were in the UK's interests to buy oil from Iran, despite EU embargo, for example) that these can be ignored on both sides.
