The energy world will be centered on electricity, with green hydrogen becoming a major player by 2030. The solar PV and energy storage industries will develop rapidly, expanding from a few countries to the entire world. Power plants will generate electricity from renewable sources in lakes and near-shore marine areas. An "energy Internet" will emerge, utilizing digital technologies to connect generation, grid, load, and storage, including virtual power plants and an energy cloud. Network-wide intelligence will be a reality.
