The Smart Energy
Systems are more efficient
In the past, most products and applications were developed stand-alone, if and when a need and technology appeared. Today, however, most products and applications need to fit into systems. This requires a new approach, one in which all the parts of the complex be considered together.
Electrified vehicles will allow large
savings in emissions and net energy use
A systems perspective offers additional opportunities in terms of efficiency that may not be obtainable when only individual components are considered. A good example is the use of intelligent software to control the heating or cooling of individual rooms in a building, in function of its occupancy and use. This whole-system approach is much more efficient in terms of energy use and conservation than the heating or cooling of a single room.
Perhaps the most obvious opportunity for efficiency and the systems approach lies in the end use of energy. Electrified vehicles, whether individual cars, public transport or freight, will allow large savings in emissions and net energy use. New battery technology will increase the range and decrease the charging time of vehicles, and more generally help balance the supply and demand for electricity everywhere.
Electric vehicles have the potential to become a large scale storage system that will enable further integration of renewable energy (e.g. wind and solar) into existing power grids. The batteries of individual vehicles, that are not in use, can store surplus electrical energy to release it at times of peak use. This offers undeniable advantages in terms of base load balancing and variable power generation. Nevertheless, a whole system approach will be indispensable because electrified transportation will have an important impact on grid and infrastructure design.
