Droughts boost emissions as hydropower dries up

Recent droughts caused increases in emissions of carbon dioxide and harmful air pollutants from power generation in several western states as fossil fuels came online to replace hampered hydroelectric power. A new study quantifies the impact.

Inventory indicates who goes solar and why

Stanford researchers have identified the GPS locations and sizes of almost all U.S. solar power installations from a billion images. Using the data, which are public, they identified factors that promote the use of solar energy and those that discourage it.

Square one for U.S. nuclear waste management program

Thousands of tons of highly radioactive spent fuel are in temporary storage in 35 states, with no permanent solution being discussed. International experts led by Stanford show how to end this status quo.

Stanford to go 100 percent solar by 2021

A second solar-generating plant, to be built in the next three years, will complete the university’s transition to clean power and further shrink campus greenhouse gas emissions.

Watching nanoparticle photoreactions

Stanford researchers retooled an electron microscope to work with visible light and gas flow, making it possible to watch a photochemical reaction as it swept across a nanoparticle the size of a cold virus.
