Personally, I don't care about these statistics. The point I was trying to make was that under capitalism any industry has the goal to make huge amounts of profit. Coal, nuclear you name it. Nothing is about sustainability, unless it is related to greenwashing. So I don't trust their approach, including the safety of these places. Also the need for more power is for industry expansion, not to heat our homes for instance.
[By the way, I am not a communist. Mondragon is a model of non-capitalistic industrial development that has been successfully expanding since the 1950's. By no means am I saying their approach is perfect, nor that perfection is the goal. Their example is important tho cause we can learn from them. For the Cleveland Model, they used Modragon's input. They refers to Gar Alperorovitz amongst others]
