Energy storage-a key technology for global energy sustainability

摘要

The equality of life today is dependent upon access to a bountiful supply of cheap energy. For a sustainable future, the energy should be derived from non-fossil sources; ideally, it should also be reliable and safe, flexible in use, afforadable, and limitless. This paper examines the present global use of energy in its various forms, and considers projections for the year 2020 with particular attention to the harnessing of 'clean' and renewable forms of energy for electricity generation and road transportation.
