<strong>EWE</strong> – Ten assumptions for the futureENERGY CONSERVATIONENERGY EFFICIENCYRENEWABLE ENERGIESE 3<strong>EWE</strong> has a visionTo ensure• efficient• economic and• environmentally compatibleenergy supply we have drawn up tenassumptions jointly with renowned scientists.The BULLENSEE ASSUMPTIONSThe core statements and recommendations ofthe assumptions are aimed at:• Conserving even more energy• Boosting energy efficiency significantly• Developing renewable energy sourcesThe BULLENSEE ASSUMPTIONS point the way,among other things, for our research anddevelopment activities.<strong>EWE</strong> – Into the future with energy 22


The e³ programme:New prospects for energy supplyA continuation of the idea behind the Bullensee Assumptions• In the future, an increasing number ofprivate households and businesses willproduce electricity as well as using it.• Plants that produce electricity fromrenewable energies and small powerplants that generate both electricity andheat will become increasingly popular.• This trend will give people theopportunity to share responsibility forthe energy supply of the future andbecome less dependent onconventional large-scale power plants.<strong>EWE</strong> – Into the future with energy 23


<strong>EWE</strong> – Conservation potential for the futureNetworking of all areasWith the <strong>EWE</strong> Box as the data interface in thehome, conservation potential can be enhanced bymeans of:• Bidirectional communicationMonitorScreen19.00°• Smart devices and facilities• Integration into a decentralised energymanagement systemWWW• Customer-specific tariffsTest region – 400 customers<strong>EWE</strong>’s Ems/Weser/Elbe regionRouter<strong>EWE</strong> BOXWesterstede (city)Oldenburg(city)Oldenburg(district)Cloppenburg(district)Natural gas Electricity<strong>EWE</strong> – Into the future with energy 24

In timeof high prices, the fridge consumes no power.• Other devices like a dishwasher or a washing machine can also be part ofdistributed energy system<strong>EWE</strong> – Into the future with energy 25


eMobility – A strategic partnershipin the field of electric mobilityEco-friendly motorised transportation and mobile electricity storage devices havea part to play in the energy supply of the future• <strong>EWE</strong> and Karmann (Osnabrück) areworking together in the field of electricmobility• A number of pilot vehicles will be constructedbetween 2009 and 2011. Thecars will be used for joint research.• The electric vehicles will be incorporatedin <strong>EWE</strong>'s electricity and telecommunicationsnetwork and intelligent controlsystems will be developed for batteryand network managementThe rechargeable batteries (blue) are integrated intothe floor of the E3 car to save space.<strong>EWE</strong> – Into the future with energy 26
