She represents the Commission as a member of DWR’s 2009 State Water Plan Update Steering Committee and as a member of the Water-Energy Subgroup to the Governor’s Climate Action Team.

As program manager, she recently completed the California Energy Commission’s Integrated Energy Policy Report proceeding, producing the state’s primary energy policy document. Since joining the Energy Commission in 1992, Ms. White has held positions as a water resource analyst and project manager in the Energy Commission’s power plant siting regulatory program, energy program and policy analyst, and energy policy advisor to former Chairman Jackalyne Pfannenstiel. Previously she was a legislative analyst for California Assemblywoman Marguerite Archie-Hudson and Assemblyman Phil Isenberg.

Ms. White holds a BS in Biochemistry from University of California at Davis and was a California Assembly Fellow.

Amul Sathe

Amul Sathe is a Managing Consultant in the Energy Efficiency & Sustainability Strategies group of Navigant Consulting’s Energy Practice. His work has focused on the water-energy nexus, including serving as principal investigator for two studies for the CPUC on the embedded energy in water in the state of California.  Mr. Sathe brings a strong understanding of the energy use by water supply, conveyance, treatment, distribution, and wastewater infrastructure.  He also focuses on analyzing technologies and strategies to improve utility energy efficiency programs.

Prior to joining Navigant Consulting, Mr. Sathe was a summer fellow with the Natural Resources Defense Council and intern at the EPA’s National Vehicle and Fuel Emissions Laboratory.  He received his B.S. in Mechanical Engineering from the University of Michigan and his M.S. in Mechanical Engineering from Stanford University where he researched the economics of carbon abatement options for California.

Ocean Friendly Gardens

Approximately half of all residential water use in California is for outdoor purposes—and, of that, the majority is used for watering lawns and gardens.  In total approximately 1,300,000 acre feet of water is used for watering lawns and gardens; enough to cover the entire County of Los Angeles with six inches of water.  Producing, transporting, treating and delivering that water requires a significant amount of energy.  In a state that had below-normal precipitation in 8 of the last 10 years (including a 3-year drought), can using such significant amounts of water (and related energy) in this manner be considered sustainable?

New technologies and approaches allow for greater efficiency of outdoor irrigation.  Options range from high efficiency nozzle replacements on sprinklers to weather sensing irrigation controllers.   Meanwhile, some have suggested outright replacement of grass with synthetic turf.  However, one option stands out for not only reducing water use but also adding to the property values of California homes, while at the same time reducing ocean pollution: ocean friendly gardens (sometimes referred to as xeriscaping).

Ocean friendly gardens utilize drought resistant California native plants in plots that are designed to capture home stormwater runoff.  They require little, if any, irrigation.  Water is supplied to the gardens by rerouting downspouts that would normally send rainwater to the streets or sewer systems—water that would otherwise wash pollutants such as fertilizers, pesticides and oil into California’s rivers and ultimately pollute our oceans and beaches.  Ocean friendly gardens are specially designed to retain the influx of storm water and achieve near-zero runoff.  Contours and dry creek beds built into the landscapes retain water, allowing it to percolate into the ground.

Water Energy

The nation’s water and energy resources are inextricably entwined. Significant energy is used by water infrastructure to pump, treat, transport, heat, cool, and recycle water. At the same time, a significant amount of water is also required to produce electricity.

Growing population is increasing the demand for water and the energy needed to deliver and treat it. Meanwhile, climate change threatens to adversely affect existing water resources, demanding new methods of mitigation and adaptation. Without advances in technology, water-related energy use is likely to grow significantly. This growth will be caused by increasing water conveyance and treatment requirements.

With the assistance of its Water-Energy Advisory Committee, the Alliance is exploring opportunities for optimizing the state’s vital water and energy resources on a fully integrated basis and is documenting strategies for water agencies to reduce their own energy use and supply more sustainable water. As part this effort the Alliance issued its study of “The Role of Recycled Water in Energy Efficiency and Greenhouse Gas Reduction” in May 2008. That study concluded that substantial water, energy and environmental benefits were achievable by accelerating development and use of recycled water in Southern California.

To ensure a truly sustainable future for California, we must better understand the water-energy nexus and implement mutually beneficial strategies to improve the sustainable development and use of water and energy resources.

Green Local Government

Local governments wield significant influence and authority that can drive environmental sustainability within their jurisdictions. In addition to moderating their own resource and operational decisions, local governments can substantially influence the resource behavior and associated carbon impacts of their constituents and other key stakeholders through a variety of policies, plans and actions.

In its Long Term Energy Efficiency Strategic Plan, the California Public Utilities Commission (CPUC) established a strategic framework for helping local governments advance sustainability within their jurisdictions.

The California Sustainability Alliance has embarked upon multiple activities to help local governments implement these strategies.

Green Buildings

In September 2008, the California Public Utilities Commission adopted the most aggressive energy efficiency goals in the nation through its Long-Term Energy Efficiency Strategic Plan (CEESP).

The CEESP identified commercial buildings as the single largest users of energy in California, accounting for more than 38% of California’s electricity consumption and 25% of its natural gas use.  Office buildings account for 25% of all energy used by this sector.   

The CEESP established the following goals for commercial buildings:

  • Zero net energy performance for all new commercial construction by 2030
  • Fifty-percent (50%) of existing buildings achieve zero net energy performance by 2030

The California Sustainability Alliance assembled an expert group of professionals with substantial experience in commercial real estate to develop a pilot project designed to significantly accelerate development of green buildings in California.  Through a series of workshops, the Alliance’s Green Buildings Advisory Committee observed that in California, much more office space is leased (90%) than is owned (10%).  The Alliance’s Advisors strongly recommended focusing on greening the 90% of California’s existing office buildings that are leased.

The Alliance thus embarked upon a Green Leases Initiative that commenced with development of a Green Leases Toolkit 2.0 that creates a template for landlords and tenants to integrate green elements into commercial office leases.

In May 2009, the Alliance published a study exploring the opportunities and constraints in the greening of leased office space in California. Click here for the full report.

Zero net purchases of energy, typically achieved by first making a building or system as energy efficient as possible, and then meeting its net energy requirements through self production of energy, usually through a distributed renewable or "clean" (zero emissions) resource.
