Advocacy group Vote Solar named Sachu Constantine as its new executive director.

Constantine is Vote Solar’s second executive director, following the term of co-founder Adam Browning, who led the organization through its first 20 years.

In a statement, Constantine said that he would guide Vote Solar to “advance policies and programs that address the previous inequities of our fossil fuel dominant energy system and benefit communities that have historically been left out of the decision-making process.”

Zaid Ashai, Vote Solar’s board chair and CEO of Nexamp said “Sachu embodies Vote Solar’s core values and has a proven track record of strategic leadership.” He said that Constantine’s skill at scaling “powerful solar solutions in the face of the mounting climate crisis” will enable the organization to “drive even greater solar adoption as we grow our impact across the country.”

Since 2017, Constantine has served as Vote Solar’s regulatory managing director, and most recently as the organization’s interim executive director. Prior to joining Vote Solar, he spent five years as the director of policy at the Center for Sustainable Energy. While there, he was responsible for directing policy, regulatory and legislative efforts as well as building its reputation as a regional, state and national leader in the clean energy arena. He has also worked at SunPower Corporation, the California Public Utilities Commission and the Alliance to Save Energy.

Vote Solar is a 501(c)3 nonprofit that claims more than 94,000 members nationwide. It advocates for state policies and programs that promote clean energy and aim to achieve what it said is a more “environmentally just society.”
