Any safety/utility tips for the summer?

So since summer is upon us and we're already facing brown outs, not to mention increased fire hazard, what can I do to stay ahead of trouble?

Do you know where I can have solar chargers? Is that even recommended? Do I need flash lights? Extra water storage? Any electricity tips?

I'd appreciate your help, because I'm a busy guy but I want my family to be safe and comfy here while I'm at work
