Board Bios

Bruce Karney is s a marketing professional who has lived in Mountain View since 1981.  In 2007 he led a city-wide group of 119 Mountain View homeowners who purchased solar panels at a 35% discount.  He subsequently joined SolarCity when it was a small startup to lead group purchasing programs in other cities.  Bruce retired from the solar industry in 2012 and is now a full-time environmental activist.  

In 2008 and again in 2017 he was elected as Chair of Mountain View's Environmental Sustainability Task Force (ESTF).  The recommendations from the 2008 Task Force provided the basis for the City's Environmental Sustainability Action Plans from 2009 to 2018, and the recommendations from the second Task Force provide a pathway for achieving the City's goals for 2019-2030.  

Bruce championed the creation of Carbon Free Silicon Valley (CFSV) to bring together environmental advocates from San Mateo and Santa Clara Counties.  He serves on the Board of CFSV.

He has a BS in Mathematical Sciences from Stanford and an MS in Management Science from UC Berkeley. He is also a graduate of Leadership Mountain View and Acterra's "Be the Change" programs, and has held several leadership roles in the Old Mountain View Neighborhood Association.

Mike Balma is the Development Director and a board member for the nonprofit SunWork. SunWork installs solar systems for home owners that have a low electric bill along with the help of trained volunteers.  Mike has completed business development and marketing projects for several solar companies. Mike helped lead the Performance Committee for SunSpec, a nonprofit solar industry alliance pursuing information standards that address operational aspects of PV power plants on the smart grid. He also delivers solar workshops for residents of numerous Bay Area cities.

Mike had an extensive marketing career with Hewlett-Packard including helping build HP’s open source business. He previously worked for SRI International, consulting on renewable energy technologies including solar, wind and biomass. He has a Chemical Engineering degree and an MBA.  Mike served on Mountain View's Environmental Sustainability Task Forces in 2008 and 2017-18.

Bruce Naegel's career started in the biomedical industry. He moved to Computer Data Storage (hardware and software) where he held positions in program and product management.  As part of releasing award-winning products, He spoke at industry conferences and published articles in trade publications. He also led a standards committee group on measuring performance.

His passion for sustainability was ignited by a news article which stated it would cost half a billion dollars to resettle an Alaskan village with about 2000 people threatened with sea level rise.

He then found some like-minded people at Veritas Symantec.  Some of them realized that Veritas software can be configured to save energy in a data center.  This effort yielded an energy ROI program, industry conference presentations, and a sales campaign yielding seven and eight figure software deals. Three years ago, he joined Sustainable Silicon Valley.  In the last year his focus was in Metrics and Research. That included numerous blog articles and a set of industry publications on visualizing the drought. He is part of a team working to bring energy efficiency to a disadvantaged community.  Bruce led the Measurement and Metrics Working Group of the Mountain View's 2017-18 Environmental Sustainability Task Force.
