What’s Happening with California’s Gasoline Supply?

Union of Concerned Scientists

In the next few years, California should modernize its gasoline regulations to reflect changes in vehicle emissions technology and the latest science, which can make the gasoline market more flexible and competitive while protecting air quality and public health. emissions by slightly more than the increase associated with the fuel change.

Nearly Half of US Breathes Unhealthy Levels of Pollution—Cars and Trucks Largely to Blame

Union of Concerned Scientists

These emissions, which in 2022 were 37.4 referred to as secondary emissions – is formed in the atmosphere from precursor pollutants that also originate from the combustion in fossil-fuel powered engines, such as nitrogen oxides (NO x ), sulfur dioxide (SO 2 ) and volatile organic compounds (VOCs). Secondary PM 2.5

Five Ways Offshore Wind Benefits Us All 

Union of Concerned Scientists

While the benefits of the technology are clear to many, its worth considering the fuller range from time to time. And for places where the water gets deep quickly as you move away from land, like off the West Coast and in the Gulf of Maine, floating offshore wind technology is maturing rapidly.

Are There Enough Materials to Manufacture All the Electric Vehicles Needed?  

Union of Concerned Scientists

Research shows there are enough explored or prospective reserves to electrify the global transportation sector using current technology if a high amount of battery recycling occurs. Reserve estimations are therefore much less than total resources and fluctuate based on material value, mineral exploration, and technological development.
