What sort of curtains for french door/ bay window

[AlwaysTheOneWaiting]

Hello
I have just rented a new place and need to sort out curtains for it.
What would you suggest for this room that leads to the garden?
The doors would need long curtains but these would then be blocking the radiators which wouldn't be great considering the energy prices.

Any suggestions?

How about a pair of full length curtains to cover the entire back wall, doors and the two narrow windows and matching Roman blinds for the windows above your radiators?

Thanks for the suggestion @rosegoldwatcher
I suppose that would be a feasible option, can't really think of anything else!
