Third of world’s energy needs should come from electricity by 2035, says Murat Kurum, as priorities set out for this year’s UN climate summit

The world should aim to meet a third of its energy needs from electricity within a decade to cut greenhouse gas emissions, the host of the next UN climate summit has said.

While about a third of global electricity generation already comes from renewable sources, other energy-intensive sectors – chiefly transport, heating and industries – have lagged behind. Close to four-fifths of final energy still comes from fossil fuels, as a result.

Datacentre off Shanghai coast uses less power and water than land-based equivalent

The world’s first wind-powered underwater datacentre has started operations off the coast of Shanghai, as China presses forwards with solutions for energy challenges created by the country’s artificial intelligence boom.

The Shanghai Lingang undersea datacentre demonstration project, which launched in May, has a capacity of 24 megawatts. It is a joint effort between HiCloud Technology and China Communications Construction, a state-owned company.
