GEI will help to realize “three transitions” of energy development, namely, the transition of energy production from fossil fuel dominance to clean energy dominance, the transition of energy allocation from local balance to cross-border, international and global distribution, and the transition from coal, oil and gas in energy consumption to electric-centric consumption. By 2050, the share of clean energy in primary energy consumption will increase to 72% which will become the dominant energy source. The installed capacity of clean energy will increase to 22.3TW, accounting for 83% of total installed power generation capacity, leading to a radical change in energy mix.
GEI effectively responses to climate change. By 2050, clean energy will annually replace fossil energy equaling to 18.6 billion tons of standard coal. CO2 emissions from energy consumption will fall to around 11.8 billion tons which is only half of that in 1990. By 2065, net carbon emissions will be realized, which promises to achieve the goal of the Paris Agreement to control the global temperature rise within 2°C. 2) It controls air pollution. Emissions of sulfur dioxide, nitrogen oxides and respirable particulate matter in the world will have an annual decrease of 250 million tons, 240 million tons and 140 million tons respectively. 3) It reduces the damage to the environment. GEI helps to reduce water pollution and ecological damage caused by fossil energy extraction, processing, transportation, storage and combustion.
Total investment on electricity sources and grids of GEI is expected to reach USD 38 trillion, (including USD 390 billion on backbone grids). The investment will stimulate the global economy to increase by 0.2 percent annually, and help to create 100 million jobs. By 2050, the annual per capita electricity consumption will increase to about 6,200 kWh, basically ensuring universal power access for all, reducing the annual electricity expenditure about USD 1.8 trillion.
GEI pushes humankind to turn from competing for fossil energy to sharing and developing clean energy with joint efforts. It increases mutual trust in politics and creates a new pattern of energy security featuring cooperation, mutual benefit and win-win results. It helps to convert resource advantages in underdeveloped regions into economic advantages, and narrow the gap between rich and poor regions to realize common prosperity.
