Members of the Organization for Economic Cooperation and Development (OECD) will need to invest more than $7.6 trillion over the next 25 years to meet their energy policy goals, further reduce emissions and create a more sustainable system for producing electricity from renewables and cleaner fuels such as natural gas, the World Economic Forum's "Future of Electricity" platform said in a report written with Bain & Company. They will also need to invest heavily in modernizing, expanding and decentralizing their power grids to make them more robust and resilient.
