Technologies for Sustainability Systems

9.0 Overview



Electricity is a heavily relied upon commodity, availability of which is critical in every part of modern world operation. In any sustainability model, power systems and management are of primary importance, and the current trends in energy management are highly technological. Innovations and introduction of smart metering and response demand technologies should make it possible to match the versatility of the energy conversion systems with the growing and "spiky" electricity demand. The evident goals of new technological developments are to survive, avoid crisis, and finally build an energy distribution system that is flexible and highly efficient in all circumstances. This lesson touches upon different sides of this complex task.

Learning Objectives

By the end of this lesson, you should be able to:

  • describe how the power grid works and what the current challenges are;
  • explain the "Smart Grid" strategy and list the key technologies involved in it;
  • discuss the role of distributed power generation systems in energy sustainability;
  • articulate the benefits of specific demand-response technologies.


You will be asked to read the following items throughout your lesson. Look for these readings in the required reading boxes throughout the lesson pages.
