The Inland Empire Utilities Agency (IEUA), located in the southwestern corner of San Bernardino County, serves one of the most rapidly urbanizing regions in Southern California. As a result, water demand in the region has increased substantially in recent years and is projected to continue growing at a high rate over the next 20 years. Currently, IEUA is required to treat all wastewater to tertiary standards. Therefore, to provide this recycled water to end users, IEUA’s only incremental energy cost is for distribution, and its major constraint is the capacity of existing infrastructure. IEUA plans to accelerate implementation of needed infrastructure to fully apply all of its available recycled water going forward.

Ontario relies on four main sources of water to meet its current demand: potable groundwater pumped from its groundwater wells in the Central region of the Chino Basin, imported water from the State Water Project (SWP), potable water from the Chino Desalter Authority (CDA), and recycled water from the Inland Empire Utilities Agency (IEUA). Ontario’s main source of water is groundwater from its Chino Basin wells. The City’s projected demand emphasizes the importance of local supplies, which typically are cheaper and more dependable than imported supplies. The potential for recycled water use is high: since all wastewater in the City must be treated to tertiary standards, the only additional energy needed to use recycled water is the energy to distribute it.

With a dry, Mediterranean climate, San Diego has limited local water supplies. The San Diego County Water Authority (SDCWA) provides the majority of the City’s potable water supplies, most of which are imported from northern California (the Sacramento‐San Joaquin delta) or the Colorado River. This profile details the city’s current and projected water demand, supply, energy intensity, cost, and potential for recycled water use.

Los Angeles is the second largest city in the nation with an area of 464 square miles and population of four million. The city relies on four primary sources of water: imported water from the Los Angeles Aqueduct, the State Water Project, and the Colorado River; and local groundwater. Recycled water has played a relatively small role in the overall water supply, meeting only 1% of its total water demand today. Its relative importance, however, is increasing to meet water demands for both industry and the irrigation needs of its parks and greenbelts.

In summer 2007, the California Sustainability Alliance (Alliance) embarked upon a “green leasing” initiative to develop and implement strategies and tools designed to overcome the primary barriers to greening the 90% of California’s office space that is leased. The Alliance developed and issued a Green Leasing Toolkit on May 1, 2008. This report presents version 2.0 of the Green Leasing Toolkit and summarizes the Alliance’s recommendations for accelerating the greening of California’s leased office space.

In November 2007, the California Sustainability Alliance and Southern California Gas Company invited representatives from ten leading utilities across the nation to deliberate on challenges and opportunities presented by the emerging sustainability paradigm, as they work to develop future energy efficiency programs. The roundtable provided an opportunity for these leading thinkers to learn from each other, and to view their own programs in a new light. This report offers a wide range of definitions of sustainability, discusses the role of sustainability in utility programs, and addresses the primary drivers of - and barriers to - sustainability.
