During my career I have worked as an advocate for protecting wild places and creatures as well as a proponent of sustainable energy development. While there has seldom been conflict between these two goals, the overshadowing issue of global climate change has forced them together in unexpected ways.[read more]

University Microgrid Manages Multiple Generation Assets

October 21, 2014 by Christine Hertzog

Combined heat and power tech are sometimes overlooked as assets that can be deployed in Smart Grids and microgrids in North America. Also known as cogeneration, it is defined as the production of electricity and useful thermal energy from a single fuel source, typically located at the point of consumption.[read more]

How Microsynchrophasors Could Keep Solar-Saturated Grids Stable
