Coal trains and terminal operations add a significant amount of fine particulate matter (PM 2.5 ) pollution to urban areas—more so than other freight or passenger trains— according to a study conducted in Richmond, California, by the University of California, Davis. The results indicate coal trains add on average 8.32

The carbon pollution from electricity varies based on local energy production methods. For instance, electricity generated from coal or natural gas is associated with higher carbon emissions, while renewable sources like wind or solar energy contribute negligible carbon pollution.

New research by a team from the US, China and Japan focusing on the Houston, Texas area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea. ““The very existence of the Houston area favors stagnation.”

Like many other people, we were writing articles around 2000 about the decline in China’s energy consumption in the late 1990s. Whereas the last version of the Databook did not even have data on wind and solar power generation, China is now among the top wind power producers in the world. It was underreported.

—Jesse Jenkins, Princeton University When I entered the field, commercial wind was starting to scale up and the questions were about engineering feasibility. What was the maximum share of wind that we could have in the system without blowing it up—5 percent or 20 percent or 30 percent? What about the pitfalls with energy modeling?

First, some background from the New York Times : The rule increasingly limits the amount of pollution allowed from tailpipes over time so that, by 2032, more than half the new cars sold in the United States would most likely be zero-emissions vehicles in order for carmakers to meet the standards. It very much is not. Soapbox, off.

from the shifting of transportation’s air pollution from urban tailpipes to rural power plants—is distributed to predominately rural communities the incomes of which are on average lower than the cities in which the EVs are used. In prior research, we calculated health impacts of PM 2.5 —Ji et al. for nuclear power.
