What was the winning generation technology in 2022 in Spain? According to preliminary data from Red Eléctrica, it is natural gas combined cycles, responsible for 24.7% of all electricity generated. It is followed by wind power, with 22.2%, and then nuclear power. What does this leadership of combined cycles imply? That Spain has emitted CO2 through a tube. And is that a gas combined cycle power plant emits about 0.4 tons of CO2 for every MWh of electricity it produces, an emission for which it has to pay rights and that makes the price even more expensive.In 2017, gas generated 36,000 gigawatt hours, with nuclear as leader and coal producing almost as many GWh as wind. In 2019, things turn around as thermal shuts down and nuclear and cycle almost tied as generation leaders (55,800 GWh to 55,200 GWh).Who has filled the coal gap? Since 2017, wind has increased its generation by 27.7% (47,907 GWh to 61,176 GWh); photovoltaic, by 231% (8,398 GWh to 27,864 GWh); nuclear, by 0.8% (55,539 GWh to 55,984 GWh and gas cycles, by 84%, from 37,066 GWh to 68,138).We burn more gas than ever, we emit CO2 without regard and we put an end to nuclear because it generates waste that can be treated without risk and that is already being buried for eternity in Finland, in a storage called Onkalo, Finnish for cave. There, the radiation will be surrounded by bentonite clay inside a shaft drilled in granite at 420 meters. Could these barriers withstand a new ice age? That bed is one of the oldest geological formations in Europe, 1.8 million years old.The reality is that Spain has put an end in 2022 to 13 "green" years in which the first generation technology did not emit CO2: nuclear, only dethroned in 2021 by wind.Was this the ecological transition?what will happen when nuclear is closed? What technology will support the system? The experts are clear: gas cycles at an unstable and polluting price. What are they doing in the rest of the world? From China to Russia, the USA, France and even Sweden, they are betting on building more nuclear power plants and extending the life of their plants. Another "nuclear boom.
