4 Global Energy Trend Dwindling resources require efficient energy management. Dwindling energy resources combined with growth in electrical energy demand of 2.4% p.a.* worldwide forces us to use energy wisely. energy is becoming a standard issue for all industrial, commercial and household applications. Higher pollution, emissions and damage to the climate require clean solutions. Pollution, along with environmental and climate protection have become global concerns. Reducing pollution by minimizing energy wastage is becoming a standard requirement for all areas of life. Infineon contributes to efficient energy management and to the effective reduction of pollution and emission. We deliver innovative, high-performance solutions with best-in-class technologies that help our customers save energy and reduce pollution. We enable the use of available resources as efficiently as possible.

8 The Negawatt Defined It has two main uses 1.The electrical energy available as a result of the application of consumption efficiencies. 2. An arbitrage way of supplying additional electrical energy to consumers without increased generation capacity by the creation of a market for trading of increased efficiency. Negawatt power is a term coined and introduced by Amory Lovins in a 1989 speech. This technique works by utilising consumption efficiency to increase available market supply rather than by increasing plant generation capacity. This "virtual generation" method can supply growth of supply by increasing efficiencies rather than increasing generation.
