Can energy sustainability (ES) be achieved?
• ES is the starting point of a better future • How we will achieve ES and if we can do it at
all is a complex question that depends on:– Investment and progress on research and
development– New industry and training of workforce – Government involvement and new policies – Change in the attitude of our society…
