I have seen some data from the McKinsey Global Institute that has appeared in an article entitled: Decarbonization Is Our Greatest Challenge , which estimates the cost of the global energy transition to reach a sustainable energy situation throughout the world.
I am clear that it is a very approximate estimate, but it points to a figure of 275 trillion dollars between the years 2021 and 2050. I do not know how they have arrived at that figure, and I am not worried about its precision, but about its magnitude.
And especially if it is compared with important projects in history such as the sending of man to the Moon, or other similar ones. The people at McKinsey have made a very simple comparison based on cubes, so that we can see the magnitude of the figures that we are now talking about, and a photo is shown below.
This effort is something that no country can carry out, and the effort of all is required, especially the richest, since the poor do not have the economic capacity to undertake it.
These figures mean of the order of almost 10 trillion a year, which represent 10% of the world's global product. And since the poor are not going to be able to contribute anything, the richest should contribute in the order of almost 15% of the annual economic product.
That is an immense economic effort, which I think will not be addressed, since it would have a direct impact on the lives of many people, almost all of us. And no one is willing to tighten their belt so much.
And this is just one more indication (another one) that decarbonization is not going to be achieved in the necessary timeframes, and that everyone in their own way will suffer the corresponding consequences.
And as always, the poor will be the most affected. Injustices of life
