His geothermal experience also includes consulting and job transfer work at other projects in the western U.S. He enjoys staying involved in the Geysers and has represented the industry giving tours, volunteering time at informational booths at various local, county and state fairs. At the State Fair he was a goodwill ambassador for Lake County which included education and promotion of the geothermal industry with the general public. Jay also became a member of an associate organization, the Geothermal Resources Council (GRC), in 1983 and presently remains an active member which has similar goals in promoting the geothermal industry on a world-wide level.
