In this presentation given to the Berlin Conference on the Human Dimensions of Global Environmental Change, Amory Lovins explains how energy can be used in a way that saves money. He argues that this will solve the climate, oil, and proliferation problems, not at a cost but at a profit. Lovins shows evidence that climate protection can be profitable for business. As an example of a company using less energy and making a profit is the Hypercar. In this presentation, Lovins also explains negawatts, his views on nuclear power, and strategies for implementing programs to limit climate change.
