China has unveiled a proposal for a $50-trillion global electricity network that would help combat pollution and the effects of climate change, NBC News reported.
The plan envisions linking existing and future solar farms, wind turbines and electricity plants in Asia, Europe, Africa and the Americas, according to the head of State Grid Corporation of China.
The proposal is in its initial stages and would require huge investment from around the world. If it goes ahead, it would be the world's largest infrastructure project. According to backers, the network could be operational by 2050.
