Power Sources

VCE is working towards a clean energy future.

VCE is committed to providing high levels of renewable energy and low levels of carbon to the communities it serves. Here’s what that means, and where our energy comes from.

Renewable Energy

Renewable energy comes from sources that are constantly replenished naturally. Using renewable sources for electricity produces no additional carbon emissions. Some sources even provide environmental advantages—such as solar farms that are constructed with pollinator-friendly habitats, and economic advantages—creating new local jobs for their construction and operation.

The renewable sources in VCE’s current electricity mix include solar, wind, biomass, bio-waste, geothermal, and small hydroelectric. Large-scale hydroelectric is not considered to be renewable by the California Energy Commission due to its lasting impacts on ecosystems.

Carbon-free Energy

In contrast to fossil fuels, carbon-free energy creates no carbon emissions when generating electricity. All of VCE’s renewable energy sources are carbon-free. But not all carbon-free energy is considered renewable.

For example, nuclear energy contains virtually no carbon but is not considered renewable—the disposal of hazardous nuclear waste often disproportionately affects indigenous lands, waters, and communities. So while both renewable and carbon-free sources help us to curb the greenhouse gas emissions associated with climate change, renewables have fewer environmental impacts.

VCE Standard Service

Our standard electricity service option is 45% renewable and 75% carbon-free. It is cost-competitive with PG&E’s standard product, which is 29% renewable. Our goal is to eventually increase the percentage of renewable energy in our standard service option.

UltraGreen Service

Our UltraGreen premium electricity service option is 100% renewable and 100% carbon-free. It is available at a slight premium—1.5 cents per kWh. That might mean a few extra dollars per month or more for your home or business, depending on how much electricity you use.

VCE’s 2020 Power Content Label is available along with our 2019 and 2018 Power Content Labels. To see more information about VCE’s power mix and how our rates compare to PG&E’s, please download the Joint Rate Mailer 2020.
