ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

EPIC: state-level renewable electricity mandates increase electricity prices up to 17% over 12 years; cost more expensive than benefit

Green Car Congress

As states take the lead in confronting climate change, a flagship policy is often Renewable Portfolio Standards (RPS). RPS programs, which require that a certain percentage of the state’s electricity come from renewable sources, currently cover 64 percent of the electricity sold in the United States.

Top Factors Affecting EV Adoption

EV Connect

Industry experts predict that electric vehicles (EV) will account for 40% of car sales by 2030. Yet for all the optimism around the electric vehicle adoption rate, certain human, structural and environmental factors still dictate the pace. Of the 289 million cars registered on US roads, barely 2 million are electric.
