The International Energy Agency (IEA) has released the much-anticipated "World Energy Outlook 2040". While it is difficult to assert that it does not predict the future, but rather provides a way to explore different possible futures, it does not escape the fact that policy makers around the world will pay attention to this report to help develop their energy agenda. .

In general, the IEA assumes four energy scenarios for 2040: the current policy scenario (CPS), which reflects the absence of changes in today's policies; the new policy scenarios (NPS), including published policies and targets; The Sustainability Scenario (SDS) aims to achieve climate goals and provide universal access to energy and clean air; while the Electrification Future Scenario (FiES), it envisions an increasingly important role for the power industry.The report pointed out that carbon dioxide emissions are rising (1.6%) in 2017), “after three years of flatness”, they may continue to “continue to slowly rise to 2040”, a trajectory “with scientific knowledge” The pace required to deal with climate change is far apart."LCOE varies by region due to different factors such as labor costs, land availability and licensing procedures. In the past five years, the global average LCOE of photovoltaic and onshore wind power has dropped by 65% and 15% respectively. In major markets, the cost of photovoltaic power is even reduced to 70%.

Specifically, the IEA found that the project cost of the global average large-scale power station fell by nearly 70% in 2017 from 2017 to 2017, while the average cost of small-scale photovoltaic systems (such as roofing projects) has dropped by 40- since 2010- 80%.Overall, the IEA found that photovoltaic power generation is becoming one of the lowest cost options for power generation, and some countries have even weakened investment in other power generation projects, especially coal-fired power generation.From a relatively positive perspective, the IEA found that by 2040, in each case, PV photovoltaic capacity will exceed all other energy sources except natural gas. Specifically, in the NPS scenario, PV PV will surpass wind power by 2025, surpass hydropower by 2030, and surpass coal power by 2040; in the FiES scenario, PV will catch up with natural gas in 2040.
