A key problem facing artificial intelligence (AI) development is the vast amount of energy the technology requires, with some experts projecting AI datacenters to be responsible for over 13% of global electricity usage by 2028. According to Xingjie Ni, associate professor of electrical engineering at the Penn State School of Electrical Engineering and Computer Science, the key to addressing this roadblock could lie in computers powered by light instead of circuitry.A key problem facing artificial intelligence (AI) development is the vast amount of energy the technology requires, with some experts projecting AI datacenters to be responsible for over 13% of global electricity usage by 2028.
