Store a back up of energy in cells before you supply a city that can allow a little extra power out on top when needed or be used for a steady steam as an immediate supply to make the rate and amount steady and constant<br><br>We've been using electricity for years and I know for a fact energy company's will have half a century's worth of data to work out what power has been required on average. All they need to do is make that amount plus maybe 20% as a backup to help keep things flowing smoothly. They have a day where there's no wind no problem allow some of the reserve out. Have a day when it's very windy no problem store it for future use<br><br>The reason why no one has come up with a solution is the energy company's that have this data aren't going to happily hand it over to renewable energy company's to help put themselves out of business
