An ambitious plan to build a massive solar farm in remote northern Australia that would transmit energy by submarine cable to Singapore is a step closer after the Australian government granted environmental approvals for the 30 billion Australian dollar ($19 billion) project Wednesday, reports AP. Australian company Sun Cable plans to build a 12,400-hectare solar farm and transport electricity to the northern Australian city of Darwin via an 800-kilometer (497-mile) overhead transmission line, then on to large-scale industrial customers in Singapore through a 4,300-kilometer (2,672-mile) submarine cable. The Australia-Asia PowerLink project aims to deliver up to six gigawatts of green electricity each year, which according to Australian Environment Minister Tanya Plibersek will “help turn Australia into a renewable energy superpower” and boost its economy.
