Dancing powerlines, think about a alternative power source

At the moment we have a unusual weather situation in the north eastern part of Netherlands. It is raining, freezing and we had a large wind from the east. Cold arriving from Russia ;-).  It is causing a phenomenon called "powerline dancing". The results do appear on the main electricity as sometimes the light is flickering and short breaks. Worst is that lights are shining brighter sometimes and that means voltage peaks which are not good for electronics. Just to be shure I left my shack off the grid. Luckely no damage to other household appliances yet. Here a video that appeared on the local TV to clarify the story (courtesy rtvnoord.nl).

This brings me back on my ideas to power my entire radioshack with alternative power. Powering the complete house is just too expensive right now. Part of my station is already on solarpower since 2012. I want to be independent from the electrical grid. What happened now is something that we as ham radio operators should think about. We are very much depending with almost everything we use in daily life from electricity that we buy from providers. But what if extreme weather, disasters, war or whatever you can think off is wiping out the electricity, what would you do? People will trust in you because you're a radio operator that is able to communicate in case of emergency. Oh yes, you can....but not without....electricity.

What would you use for a alternative power source in case of emergency? Or in preparation for a power outage?
