How about this for a list of things to do - from the media 'experts'.
* Keep multiple torches along with extra batteries
* Make sure your mobile phone is charged so you can make calls in the case of an emergency
* Use portable phone chargers
* Keep freezers and fridge doors closed
* Put a blanket over your fridges and freezers, as they will stay cold for many hours
* Turn off appliances like irons and electric fires as they could be a hazard if the power comes back on and you're not at home
* Write down a list of important contacts in case your phone dies
* Check on your neighbours.
All very elctrocentric and phone focussed, and a bit wierd.
If you are in a blackout so will most phone masts so having a fully charged phone will be no use - there are still very few solar powered masts.
What is a portable phone charger and how is it different from the ones that come with a phone?
Don't we all usually keep our fridge and freezer doors closed?
Turning things off and checking neighbours are the only worthwhile things and most of us would do those anyway: surely?
