But ... but that's what I am talking about dude. Our current lifestyle and waste of resources is the source of the problem not what ever if we use coal, oil or renewable energy. Yes we can not just do everything with renewable energy if we don't tackle the issue of Energy Sufficiency accordingly. Right now the need for energy is growing globally by 4% each year - if I am not mistaken. And that's what we have to change one way or another. It's like loosing weight. It doesn't matter how efficiently you eat your cake. At the end of the day you have to lower the intake of calories if you want to lose fat. But even if you switch to only vegetables it doesn't help you much if you still eat to many calories. Which means you can eat sometimes cake but not all the time. The increasing amount of energy we consume today is the unhealthy part. It left out some of the most important parts. We have to take in to account the increasing number of extreme weather patterns because they are one of the effects of global warming. That's hard physics. More energy in the atmosphere means more energy in storms and so on. And I am telling you we are past that point. We could have done things "smart" 30 or 40 years ago. But we have a few years left maybe 10 at most where we could avoid the worst effects from taking place. So we have only a very short amount of time to complete decarbonisation our industry. But I see no way how we will achieve those things. Same issue as you correctly said with wind energy pall ... it is not an issue of efficiency anymore. We have plenty of already efficient technology out there. We simply use to much of it. It is like with loosing fat. As I said. Even if we replace 1000 calories of cake with 2000 calories of vegetables. We still eat to much. Our industries become more and more efficient each year yet pollution is increasing. This is called a re-bound effect in energy terms which became known with the use of more efficient car engines if I remember correctly or light bulbs I am not sure. People thought with more efficient technology we would also use less energy. But the exact opposite happend. Why? Because it became cheaper. Instead of simply replacing 1 ordinary light bulb with LED lights, you had now 3 or more LED lights in place of 1 light bulb. And thus the need for energy increased. More energy had to generated. Which in turn increased the emissions of Co2 and other green house gases and so on and so forth. And we saw this taking place in many industries. We have become also very good in outsourcing pollution. Entire production lines like for electronical devices and mining of rare minerals have been shifted to the third world. This is really a very complex problem which would require to change our economies and the way we trade. We would have to drastically lower our lifestyle and change it in almost radical ways compared to what we did for the last 40 years. And I just don't see that happen. I really don't. People won't give up freely on their gadgets. I do not see people giving up on their cars, be it electrical or fuel and I don't see people giving up on flying around and all the other convenient stuff, like eating only meat once per week or something. But those are the things we would have to do at this point.
