"The prize-winning utility, one of Germany's early pioneers in the field, is owned by the old medieval market town of Schwäbisch Hall, north of Stuttgart. Most of the utility's suppliers are private people, farmers, and small businesses, as well as 'energy co-ops,' which are clean-energy facilities owned and collectively managed by a group of local investors.
'It's a complex work of art,' says van Bergen about Stadtwerke Schwäbisch Hall's daily managing of the county's energy supply. 'Local utilities and citizen-owned energy sources are just the right fit for Germany's Energiewende,' he says, referring to the German term for the country's coordinated transition to clean energy. One of the crucial take-aways from Schwäbisch Hall -- and Germany's renewable energy revolution -- is that small can be big, and become much bigger quickly.
In just a dozen years, industrial-powerhouse Germany has replaced around 31 percent of its nuclear and fossil fuel generated electricity with green power, produced overwhelmingly from moderately sized onshore wind, solar PV, hydro, and bio-energy installations..."

Multiple mall energy producers are less susceptible to attack and natural disasters as well.  In other words, they are more robust.
