Peterborough, New Hampshire [RenewableEnergyAccess.com] In this week’s edition of “Inside Renewable Energy,” Joel Glatz, who founded Frontier Energy of Maine four years ago, talks about the challenges and rewards of being in the biodiesel and bioheat business.One of the key challenges is convincing petroleum refiners and blenders to make biodiesel part of their product mix. The inability for a single biodiesel supplier to meet the demand of large petroleum businesses is central to the problem, says Glatz. Despite the difficulties ahead, Glatz sees the biodiesel and bioheat market growing dramatically in the near future. While you listen to the podcast interview, you can also read Joel’s recent RE Insider article, “Go Bioheat!” Just follow the link below.

All town buildings in Willits are powered by a solar installation, and an old hospital is being transformed into a fully green building. The origins of the renewable energy movement run deep in Willits, and off-grid living is widespread. As always, “Inside Renewable Energy” offers the latest in renewable energy news.
