80 Million Kilometers of Grid Investment Needed by 2040 to Meet Global Climate Goals: IEA
Investment in electricity grids will need to scale rapidly over the next few years in order to enable the achievement of global climate goals, according to a new report released today by the International Energy Agency (IEA).
According to the report, 80 million kilometers of power lines will need to be added or replaced by 2040, roughly equal to the entire global grid today, with investment doubling to over $600 billion per year by 2030, in order to meet all national climate and energy goals.
