The City of Fremont has made a number of local headlines this month for reports on the high number of electric vehicle owners living within its boundaries. With a population of 221,986, Fremont holds 14.3 percent of Alameda County’s 1,554,720 residents.1 But with 3,870 electric vehicle rebates issued in Alameda County since 2010 under the California Clean Vehicle Rebate Program, Fremont, with its 1,143 rebates to date, represents 29.4 percent of all-electric vehicles owned within the County.2

Fremont's EV Rebated By Month

The reason for the heightened media attention is that many people were surprised that this southern Alameda County suburb could be “the East Bay’s epicenter for electric vehicles,” questioning, “What makes it so special?” The news of increasing EV ownership in Fremont, however, is less of a surprise to those responsible for City development. As the City’s deputy director of Community Development, Dan Schoenholz, stated when pointing out that a slightly larger number of electric vehicle rebates had been issued in Fremont than in San Francisco, “San Francisco has the reputation for being a super-green city, but this shows that Fremont is quietly pushing the envelope.”

The story, in fact, fits nicely into the future vision that the City has created for itself. This is a future of sustainable urbanism, one in which Fremont has evolved beyond its early agricultural roots and post-war suburban sprawl into a center for clean technology, a mecca of cultural diversity, and the home of eco-conscious citizens. Beginning in 2011 with the City’s award-winning General Plan that strategically positioned “Sustainability” as the opening chapter for its 2030 vision, and gaining momentum with the adoption of its Climate Action Plan in 2012 to reduce greenhouse gas (GHG) emissions by 25 percent by the year 2020, the City of Fremont continues to challenge the conventional model of development with an alternative one that places the health and well-being of future generations at the forefront of policy-making.

Looking back over the last handful of years, the Fremont community has already made significant strides in reducing the environmental impact of activities taking place within its borders. Even with a 2 percent increase in population size between the years of 2005 and 2010, residents and businesses in the City of Fremont drove a total of 3.6 percent fewer miles, used 10.1 percent less energy, consumed 14.1 percent less water, and sent 30 percent less waste to the landfills. This translates into a community-wide greenhouse gas emissions reduction of nearly 11 percent, which is detailed by sector in the City’s recently published 2010 Greenhouse Gas Emissions Inventory Update to track its progress on its Climate Action Plan implementation. The graph below shows Fremont’s current progress in reaching its 2020 GHG reduction goal.

Emissions Reductions

This decrease in Fremont’s community-wide emissions can be attributed to a number of factors, including the following developments:

  • Advances in energy efficiency, including upgrades to high efficiency lighting options like CFLs and LEDs and the increasing popularity of ENERGY STAR appliances
  • Installations of renewable energy projects, with 3.5 megawatts of solar electric generating capacity throughout Fremont at the end of 2010
  • Adoption of water conservation strategies such as low-flow fixtures and water-efficient landscaping, resulting in a 17 percent decrease in per capita water consumption to 132 gallons per day by 2010
  • Promotion of green waste, food scrap, and recycling programs to encourage community members to rethink “waste” and instead reduce, reuse, recycle, and compost
  • Shorter vehicle mile commutes, with more people choosing to walk, bike, take public transit, or carpool than to drive alone
  • Improvements in the fuel economy of vehicles, including the growing popularity of hybrid electric vehicles and the emergence of electric vehicles by 2010

The influx of electric vehicles in Fremont, then, is one piece of the City’s larger sustainability puzzle, helping to address the 58 percent of community-wide emissions attributable to the transportation sector alone, as seen in the chart below.

Fremont Community Emissions By Sector

How will electric vehicles help to reduce Fremont’s transportation emissions? Consider that a conventional gas vehicle averaging 27.6 MPG and traveling 15,000 miles a year will produce more than 13,000 lbs. of CO2 annually. For each conventional vehicle replaced by an electric vehicle in Fremont, there will be approximately 8,700 fewer lbs. of CO2 emitted into the atmosphere each year.3 This is assuming that the vehicle will be charged by electricity provided by PG&E, which consists of a mix of fuel sources including natural gas (27 percent), nuclear (21 percent), renewable (19 percent), and large hydroelectric (11 percent), among others.4 Substitute the electricity from the grid with a non-emitting, on-site renewable energy source such as a rooftop solar PV system, and that electric vehicle effectively produces zero emissions.

If these figures are multiplied out, the effects that they have on overall levels of sustainability in Fremont become more tangible. Assume that an additional 10,000 residents were to replace their conventional vehicles with electric vehicles and that they charged those vehicles with energy from the grid. This would result in an annual GHG emissions reduction of at least 40,000 MTCO2, or 6.5 percent of all emissions coming from on-road passenger vehicles.5 This represents a 2.6 percent reduction in the City’s total community-wide emissions. If most of these new EV owners additionally chose to install solar on their roofs for charging their vehicles, these reductions would more than double.

While the reduction in GHG emissions is important, Fremont’s focus on sustainable urbanism also means choosing a future that looks less like the auto-oriented bedroom community of the past and one that is more encouraging of the use of trains, buses, biking and walking for day-to-day activities. The City of Fremont therefore is focusing particular attention on transit-oriented development (TOD) in the areas surrounding the Centerville Train Station, the Fremont BART Station, the potential Irvington BART Station, and the upcoming Warm Springs BART Station — as can be seen in the General Plan and in the subsequent Downtown Community and Warm Springs/South Fremont Community plans.

It is unreasonable to assume, however, that most residents will abandon use of their cars altogether. The City is therefore supportive of electric vehicles as a more sustainable alternative to conventional vehicle use and is working to encourage this through improvements in electric vehicle infrastructure. One example of this is the City’s participation in the Bay Area Climate Collaborative’s recent grant application to the California Energy Commission to fund the installation of 8 dual-port charging stations at publicly accessible and centralized locations, with the award notification anticipated by the end of this month. The City is also beginning to replace its aging fleet with EVs, with two new vehicles slated to arrive this spring.

Of course, a discussion of electric vehicles in Fremont would not be complete without mention of Tesla, one of the most recognized electric vehicle manufacturers worldwide, whose Model S manufacturing facility is located at the former NUMMI plant in Fremont’s Warm Springs District. But Tesla is not the only clean tech company that calls Fremont home; there are more than 30 clean and green tech firms in Fremont, including Oorja (fuel cells), Solaria (solar cells), Leyden Energy (lithium ion batteries), Imergy Power Systems (energy storage), and Soraa (LEDs). With such a thriving clean tech economy in its own backyard, Fremont has earned its title of “Silicon Valley East”.

So while electric vehicles are indeed helping to drive Fremont toward sustainability, they are just one of the many methods of getting there.

  • Rick Kargaard

    The simplest solution would be pv charging at work. Another would be moving your work and home closer together to allow for walking or bycycles
    To slow climate change a change in lifestyles will be necessary, not necessarilly for the worse.
    It will be a lot less painful to do it now instead of having to move to higher ground when the seas rise.

  • JamesWimberley

    “Substitute the electricity from the grid with a non-emitting, on-site renewable energy source such as a rooftop solar PV system, and that electric vehicle effectively produces zero emissions.”
    Feasible perhaps for a second car used for school runs and shopping, and at home for the rest of the day; but not for a first car used for commuting, which has to be recharged at night from non-solar sources (unless you have a home battery as big as your car’s).

    On the other hand, it’s very conservative to use PG&E’s average fuel mix as the basis for estimating ev carbon emissions. The gas generation is to meet peak afternoon load – as more rooftop solar kicks in, the peak shifts to early evening. Nighttime utility production will be almost entirely from low-carbon wind, nuclear and hydro.

    The solar/ev combination works best for second cars. For commuter cars, there’s no synergy, unless you have access to solar recharging at work, and the investments should be analysed separately.

    • Bob_Wallace

      If you put “car” panels on your roof and ship that power to the grid then you are going to displace natural gas generation. That’s the most expensive dispatchable generation.

      Then you can charge that car off late night wind.

      Carbon free charging.

      EVs are likely to greatly boost wind installations. They will create new late night profits for wind farms which will bring more investment.

      • JamesWimberley

        Quite. My point is merely that these effects are independent. The solar panels on your roof have exactly the same effect on carbon emissions whether ot not you get an ev that you charge at night. The ev reduces emissions by exactly the same amount whether or not you get the solar panels too. Yes, it’s a good idea to do both – additively not synergetically.

        • Michael B

          They’re energetically additive,
          but *financially* synergetic, no? ;-)

          i.e., the money you save from not paying for gas can help finance the panels, and the money you save from not using as much (net) utility electricity can help pay for the EV (&or its “premium”).

    • eveee

      …Or your solar panels connect to the grid and send electricity everywhere including to your car parked at work and charging during the day. The panel does not need to be where the EV is to do some good work. What about daytime peak electrical demand? Going down because rooftop and other solar are creating the ” duck curve”. Daytime solar generation is depressing daytime demand and lowering daytime costs. Users with vehicle to grid can power their homes at night during winter peaks, profiting even more and lowering utility bills and EV costs.
      The generate here, use somewhere else idea is used for apartment dwellers, also, sometimes called solar gardens.
