Howard Johns, author of energy revolution is an energy engineer, entrepreneur, business leader and activist. Following completing a degree in energy technology and environment in the early 1990s, Howard became a protestor, about energy and climate change, trying to stop amongst other things the digging of an open cast coal mine, and being evicted from a tree in the process. Moving on from saying no to the problems, Howard set about building solutions, eventually founding Southern Solar a national solar energy company, and Ovesco a locally owned renewable energy cooperative. At the same time he chaired the trade body representing the UK solar industry, finding himself once again a campaigner around energy policy in the process. A believer in solutions, Howard is convinced we have all the technology and money we need to implement the climate and energy solutions we need. It is now time for lots of people to get involved with making it happen.
