english: That's why when, in California, we try to deal with all the solar we've brought online -- we now get about 10 percent of electricity from solar -- when the sun goes down, and people come home from work and turn on their air conditioners and their TV sets, and every other appliance in the house, we need a lot of natural gas backup.
non_english: Kvôli tomu sa v Kalifornii snažíme vyrovnať s problémami, ktoré so sebou priniesli solárne panely – približne 10 % elektriny získavame zo slnka – keď zapadne slnko a ľudia prídu domov z práce a zapnú si klimatizácie a TV sety či akýkoľvek prístroj v dome, potrebujeme mnoho zemného plynu ako zálohu.
