While there have been many clean energy innovations in the United States, transitioning from a fossil fuel-based energy system has not been straightforward or affordable for the average homeowner. In 2009, Berkeley, CA voters endorsed Measure G, which created the Berkeley Climate Action Plan. The measure encompasses a range of actions to achieve a 33 percent greenhouse gas emissions reduction below 2000 levels by the year 2020 and an 80 percent reduction below 2000 levels by 2050. Cisco DeVries, then Chief of Staff to the mayor, worked with key government staff members, researchers from UC Berkeley, and solar power companies, to create Berkeley FIRST, a program providing homeowners with a cost-effective, long-term financing option to install solar panels on their roofs. The pilot program, installed on thirteen sites, allowed for a better understanding of the funding mechanism and energy savings benefits. This evolved into the statewide California FIRST program, nationally known as Property Assessed Clean Energy Program, or PACE. PACE is a national standard bearer for financing energy efficient upgrades to buildings, with 31 states and Washington D.C. enacting legislation that enables PACE financing schemes.
