Clean, Smart Micro-grids

Despite recent experiments with deregulation, the current top-down utility paradigm has remained essentially unchanged for a century. Large central station generators provide an undifferentiated power product over a high voltage transmission system. Consumer needs are not undifferentiated in two important ways. Electric applications vary dramatically in terms of the value of reliability. Consumers vary dramatically in their willingness to pay to reduce the environmental impact of their energy consumption. Utilities have started to […]

HOMER Users are Creating a New Energy Future

If the world is going to transition to a sustainable energy future, then renewable energy must eventually supply more than a 20% share of the power sector. However, large utility companies are very frank about their lack of understanding of how to integrate solar and wind power at those higher levels. That is why they continue to propose large coal plants. Utility systems can indeed have much higher shares of renewable power, as […]
