Artificial intelligence has become a focus of certain ethical concerns, but it also has some major sustainability issues. 

 A widespread transition to solar energy will depend heavily on reliable, safe, and affordable technology like batteries for energy storage and solar cells for energy conversion.

Study shows twice the average emissions rate of 11 other major U.S. production regions; paper demonstrates potential for space-based data to drive down methane loss rates.

Scientists warn that we have approximately 30 years to eliminate our dependence on fossil fuels to avoid irreparable damage to our climate and the intensifying health impacts caused by climate breakdown.

Oil produced from biomass can provide a sustainable alternative to fossil fuels. But technological challenges make it difficult to scale up production and make it economically viable.

Experimental condensed matter physicists in the Department of Physics at the University of Oklahoma have developed an approach to circumvent a major loss process that currently limits the efficiency of commercial solar cells. 

QUT researchers have proposed the design of a new carbon nanostructure made from diamond nanothreads that could one day be used for mechanical energy storage, wearable technologies, and biomedical applications.

NASA's long-term, global view of Earth from space includes data on sunlight, wind, temperature and precipitation, all key elements in understanding how our planet works.

This April marks 10 years since the Deepwater Horizon oil spill. Learn more about our efforts to restore the Gulf's ecosystem since then.

Wind, which generates less greenhouse gas emission than burning fossil fuels, is making up an increasing share of the energy production portfolio in the United States. But wind is not as efficient as coal or natural gas, causing some concern about its economic impact.
