International team: Sun and wind could help the world get rid of carbon dioxide forever
An international research team led by scientists from the University of California Irvine has concluded that most of the current demand for electricity in developed and industrialized countries can be met by a combination of wind and solar energy.
And to get to that Results Published in the journal Nature Communications and announced by the university in Official statement On November 5th, this team analyzed 39 years of hourly energy demand data in 42 major countries to assess the adequacy of wind and solar energy resources to meet the needs.
According to the study, it was found that merging the mechanisms of working with wind and solar energy together has caused the needs of those countries to be met for 72% to 91% of the time.
But it is interesting to note that this percentage was only when the use of wind energy and solar energy was combined without the use of tools to store electricity, and with the addition of only 12 hours of energy storage capacity, it was possible to raise this percentage to 94% in some countries.
Overall, the study concludes that the combined use of wind and solar energy can meet more than 80% of energy demand in many places without massive amounts of storage or excess generation capacity.

These results are promising, because the world is currently moving towards a full transition to renewable energy within the next decade or two, so it is possible to dispense with fossil fuels that emit huge amounts of carbon dioxide into the Earth’s atmosphere, and then cause further warming. .
According to the study, the full transition to these renewable energy resources can be easier for countries located at low latitudes (close to the equator), as they can rely on the availability of solar energy throughout the year.
But besides that, the study also showed that even in the case of countries far from the equator that sometimes experience recessions in both types of energy sources, countries can exchange energy lines with each other to solve this problem.
The team proposes a model in Europe, where a system could be provided that includes solar resources from Spain, Italy and Greece, with abundant winds available in the Netherlands, Denmark and the Baltic region.
This research comes against the background of the climate summit held in the Scottish city of Glasgow, which is concerned with determining the next ways to coexist with climate change, and prevent the inhabitants of our planet from emitting more carbon dioxide into the atmosphere.
