Electrical Energy is the key enabler for an integrated energy system
Generation and utilization of electrical energy is often more efficient than direct utilization of primary energy sources.
1
For maximum overall efficiency and minimum carbon footprint infrastructure-overarching (holistic) solutions are required.
3
Electricity networks allow the efficient integration of a wide range of renewable energy sources.
2
The usage of electrical energy will increase much faster than the overall energy consumption.

Together we can start right now developing the future - because the tools are already there!
Smart Grid Application at Decentralized Generation CO2 emissions are constantly
on display
wireless sensors and smart metering coupled to load
management and market driven energy supply software
car-parking for plug-in vehicles, buy or sell electricity shaving
peak loads
large centralized power plants supply the majority of power demand large and very small generation
plants need to be managed in parallel
storage plants buffer fluctuating generation
energy corridors underground by Gas
Insulated Lines or cables (DC or AC)

This document contains forward-looking statements and information – that is, statements related to future, not past, events. These statements may be identified either orally or in writing by words as “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, “will” or words of similar meaning. Such statements are based on our current expectations and certain assumptions, and are, therefore, subject to certain risks and uncertainties. A variety of factors, many of which are beyond Siemens’ control, affect its operations, performance, business strategy and results and could cause the actual results, performance or achievements of Siemens worldwide to be materially different from any future results, performance or achievements that may be expressed or implied by such forward-looking statements. For us, particular uncertainties arise, among others, from changes in general economic and business conditions, changes in currency exchange rates and interest rates, introduction of competing products or technologies by other companies, lack of acceptance of new products or services by customers targeted by Siemens worldwide, changes in business strategy and various other factors. More detailed information about certain of these factors is contained in Siemens’ filings with the SEC, which are available on the Siemens website, www.siemens.com and on the SEC’s website, www.sec.gov. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in the relevant forward-looking statement as anticipated, believed, estimated, expected, intended, planned or projected. Siemens does not intend or assume any obligation to update or revise these forward-looking statements in light of developments which differ from those anticipated.
