And we forgot how the used aluminium was made. Aluminium being thé most polluting and energy-inefficient metal to produce, and being used to make the turbine he's sitting on. When you do the math, you will find that you have just used so much (mostly coal powered) energy in creating the turbine, that they will NOT reproduce that amount. All the power that the turbine produces is basically still as polluting as coal, but the public doesn't realize. Tom 'accedentaly' forgot to mention this, which is a shame. Hope he reads this, and can do a bit more 'proper' research and number-crushing on this, and stops being all happy about that polluting 'green' turbine that he's sitting on.,(reply>), Im looking for information on aluminum manufacturing, I have never heard anything about it being energy inefficent or poluting to produce aluminum more than other metals,(reply>), +Forrest Glenn Are you asking for a source as to why we should reduce emissions for the production of turbines etc or for the original comment?,(reply>), as everyone else here, Source?,(reply>), +DerpMans Derpyskin Even if the aluminium thing is not entirely true, the problem is that people often ignore the whole life emissions of things such as wind turbines or electric cars. We shouldn't just concentrate on say the on the road emissions of an EV, but also the pollution caused in its production.,(reply>), actually the blades, and majority of the turbine itself is made of carbon fiber. Not sure where you get the aluminum idea from.
