In theory, 5G smartphones will be less taxed than current smartphones. This is because a 5G network with local 5G base stations will dramatically increase computation speeds and enable the transfer of the bulk of computation from your smartphone to the cloud. This means less battery usage for daily tasks and longer life for your battery.
Caption: "Researchers and practitioners have struggled to compare the costs of different [energy] storage technologies, because of the multiple dimensions of cost and the fact that no technology dominates along all dimensions," says Jessika Trancik, the Atlantic Richfield Career Development Assistant Professor of Energy Studies at MIT.
Our study finds that energy storage can help VRE-dominated electricity systems balance electricity supply and demand while maintaining reliability in a cost-effective manner — that in turn can support the electrification of many end-use activities beyond the electricity sector."
