Renewable energy and sustainability - an evaluation

Renewable energy advocates often invoke the goal of sustainability in order to promote their cause. Most people agree that the energy supply for a sustainable world should be based on safe, clean and renewable forms of energy. However, sustainability is a much over-used word to the point where it has become almost meaningless. This paper argues that we need to reaffirm the meaning of sustainability and use its defining principles to guide our advocacy and practice. If we ignore these principles, we run the danger of generating unrealistic expectations and mistrust, and becoming involved in practice that is questionable from a sustainability perspective. On the other hand, if we use the principles of sustainability to guide our practice and advocacy, our goals will be more achievable, our credibility will increase and our practice will become more ethical. This paper uses one model of sustainability to evaluate examples of renewable energy advocacy and practice.
