The supply of electricity from clean energy sources "must double within the next eight years to limit the global temperature rise. Otherwise, there is a risk that climate change, more extreme weather events and water stress will put ours at risk. energy security and jeopardizing the supplies of renewable energy ".
Thus the World Meteorological Organization (Omm), the UN voice on weather, climate and water, in the report "State of climate services 2022", which focuses on energy "because it is the key to international agreements on sustainable development and climate change ".
Climate risk is increasing everywhere and, in Italy, Cortina risks winter skiing due to wet snow, according to a stress test carried out in the province of Belluno and an estimate for the period 2036-2065.
Investments in renewable energy "must triple by 2050 to bring the world on a net zero trajectory" of greenhouse gas emissions by mid-century, adds the WM, noting that the energy sector "is the source of about three quarters of emissions. global greenhouse gases. Moving to clean forms of power generation, such as solar, wind and hydro, and improving energy efficiency are key if we are to thrive in the 21st century. "
The report notes that "water resources are scarce and this is a risk for electricity generation".
In 2020, 87% of global electricity generated by thermal, nuclear and hydroelectric systems depended directly on the availability of water, but there is now the risk of water stress.
