Founded by Warren T. Dewhurst, PhD, PE, the Dewhurst Group (DG) specializes in renewable energy, sustainable development, and fund management. We conduct innovative, environmentally sustainable, and socially responsible exploration and development projects, focused on renewable energy and aquaculture; as the managers of the Geothermal Development Facility for Latin America, we also award grants for the development of geothermal energy, specifically, in that region. Our prospective clients include engineering firms, developers, governments, utilities, and financial institutions.


About Dewhurst Group


Development efforts are vital to progressing from an explored resource to a confirmed, bankable, and profitable project. Development becomes the key step toward financing, construction, and eventual power generation. DG’s all-encompassing services include but are not limited to geothermal drilling, well design, well siting, civil work, geotechnical designs, infrastructure, social impact, environmental impact, and capacity building.

“From two guys and some stuff outside of the Geothermal Resources Council annual meeting to managers of one of the world’s largest geothermal risk mitigation funds, we have come a long way.  But there is always more to do.
