Going from Pump to Plug
The Union of Concerned Scientists analysis finds that EVs are significantly cheaper to fuel and maintain than gasoline vehicles, with median annual fuel savings exceeding $770. While purchase prices are generally higher, federal and state incentives can make EVs competitive or even cheaper than comparable gasoline cars. The report emphasizes the role of time-of-use (TOU) electricity rates in reducing costs and recommends policies to expand charging infrastructure and maintain purchase incentives to accelerate the transition to electric mobility.

Going from Pump to Plug
The report finds that electric vehicles (EVs) are significantly cheaper to fuel and maintain than gasoline vehicles in the US. Analysis of 60 electricity providers across the 50 largest US cities shows that at least one rate plan in every location makes EV driving cheaper than the average new gasoline vehicle, with median annual fuel savings exceeding $770. While the initial purchase price of EVs is typically higher, federal and state incentives, along with declining battery costs, are increasing affordability. The report recommends policies to expand charging infrastructure, particularly DC fast charging in urban areas, and the implementation of time-of-use (TOU) electricity rates to further reduce costs and emissions.

From Gas to Grid
The report argues that the electric vehicle revolution is inevitable due to falling battery costs and increasing consumer demand, making the urgent deployment of charging infrastructure a priority for U.S. utilities and regulators. It identifies high capital costs and unfavorable utility tariffs—specifically high demand charges—as primary barriers to the profitability of DC fast charging (DCFC). The authors advocate for a mix of Level 2 chargers for residential and workplace needs and DCFC for high-traffic corridors, supported by time-of-use (TOU) tariffs to optimize grid integration. Through case studies of California, Colorado, Hawaii, Ohio, and Texas, the report demonstrates how different regulatory environments and grid compositions influence the cost of charging and the potential for EVs to absorb excess renewable energy.

EVGO FLEET AND TARIFF ANALYSIS PHASE 1: CALIFORNIA
The analysis finds that high utility demand charges are a primary barrier to the profitability of public DCFC operators, sometimes accounting for over 90% of electricity costs. By modeling current usage data from 230 California stations across four future EV growth scenarios, the report demonstrates that proposed EV-specific tariffs from Southern California Edison (SCE) and San Diego Gas & Electric (SDG&E)—which reduce or eliminate demand charges—would significantly lower costs and enable a more sustainable business model. The authors argue for a shift toward time-varying volumetric rates and the socialization of some infrastructure costs to meet California's transportation electrification goals.

Driving Integration
The report argues that the rapid growth of electric vehicles (EVs) requires a shift in regulatory paradigms to ensure that new loads benefit rather than impair the electricity grid. It emphasizes the role of state utility regulators in designing smart charging policies, rate structures, and infrastructure ownership models. Through case studies of California and Washington, the document illustrates different approaches to EV deployment and integration, highlighting the need for adaptive regulation, such as scalable pilots and scenario-based distribution planning, to manage the unpredictable nature of EV adoption.

AN INTEGRATIVE BUSINESS MODEL FOR NET ZERO ENERGY DISTRICTS
The Rocky Mountain Institute presents a business model for net zero energy (NZE) districts that achieves life-cycle cost neutrality compared to business-as-usual (BAU) developments. The model centers on an Integrated Energy Services Provider (IESP) that manages a micro-utility, district heating and cooling, and renewable energy deployment. By shifting capital costs for heating/cooling and solar PV away from parcel developers and providing on-bill financing for energy efficiency, the model reduces upfront costs for developers and lowers total energy bills for tenants. The approach includes outcome-based energy-performance requirements enforced through a system of incentives and penalties. A case study of a 180-acre mixed-use development in a midsize U.S. city demonstrates that the model remains economically favorable even under challenging conditions such as low electricity rates and a lack of net metering.

Electric Vehicle Survey Methodology and Assumptions
The survey found that approximately 43-44% of households in California and the Northeast are technically suitable for current plug-in hybrid electric vehicles (PHEVs) based on parking, hauling, and passenger needs. Consumer interest in EVs is higher in California, where 54.63% are likely to consider one for their next vehicle, compared to 34.86% in the Northeast. The most cited barrier to ownership is the purchase price, and the most desired policy is a tax credit or rebate. While there is strong agreement that EVs reduce climate emissions, awareness of specific government and utility incentives remains low.

The Menu A list of actions that leaders can take to make their community a plug-in pioneer
The document outlines a 'menu' of 'must have' and 'nice to have' actions for municipal governments, utilities, civic groups, and businesses to facilitate the transition to plug-in vehicles. It uses a hypothetical city modeled on Denver, Colorado, to estimate that achieving a goal of 10,000 plug-in vehicles (2% of registered vehicles) over five years would result in a net cost of approximately $10 million and create 250 net new jobs, while avoiding 2 million gallons of oil annually by 2014.
