Diesel is the Reason for the Sneezin’: Cleaner Holiday Deliveries are on the Horizon

Union of Concerned Scientists

How would that change if I hopped on the electric bus route at the end of my block? A 2021 meta-analysis of over 40 peer-reviewed studies on the subject concluded that “there is no particular type of shopping that has an absolute environmental advantage and it is in no way possible to shop ourselves out of the environmental crisis.”

Ask a Scientist: Two Dozen States Can Meet 100 Percent of Electricity Demand with Renewables by 2035

Union of Concerned Scientists

Nearly all of the alliance members have a renewable electricity standard (RES), which requires utilities in their jurisdiction to increase their use of renewable energy to a particular percentage by a specific year. Under the no-new-policy scenario, sulfur dioxide and nitrogen oxides decline only by 27 percent and 18 percent, respectively.

Ask a Scientist: UCS Transportation Program Adds Equitable Mobility to its Portfolio

Union of Concerned Scientists

In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. Soon thereafter, it began extolling the virtues of battery electric vehicles , which it continues to do today.

Ask a Scientist: Gas Plants Disproportionately Harm Marginalized Communities

Union of Concerned Scientists

Gas, which now generates 40 percent of US electricity, is considered by some to be critical to maintain grid reliability. For example, Dominion Energy, an electric and gas utility in Virginia, is planning to build a mammoth 1,000-megawatt gas plant in an area with a high percentage of residents who are people of color and low-income.

Reliance on Gas Power Plants Fuels Inequity

Union of Concerned Scientists

Most notable of these polluting emissions are nitrogen oxides (NOx). Higher and more volatile energy bills An electric system that is over-reliant on gas can contribute to higher and more volatile electricity bills. It indeed accounts for 40% of the electricity currently generated for the grid.

Replacing California’s Oldest and Dirtiest Cars Will Save Money and Lives

Union of Concerned Scientists

Older vehicles (pre-2004) make up 19% of the state’s passenger vehicles and only 12% of miles driven, yet they emit almost 3 times as much smog-forming, nitrogen-oxide pollution as all 2004 and later vehicles combined. Evaluate and adjust incentive programs based on changing conditions in the electric vehicle market.

Ask a Scientist: The US Has to Do More to Meet Its Carbon Emissions Reduction Goals

Union of Concerned Scientists

The legislation committed nearly $400 billion to support, among other things, wind and solar power, battery storage, electric vehicles, and other clean energy technologies that will make a significant dent in US heat-trapping emissions. First, decarbonizing the electricity sector mainly with wind and solar to replace coal and fossil gas.
