@n5 Nonsense. There is no free lunch in the physical world. There's a cost borne by everything, even solar and wind, even if it's the acres of farmland denuded of life from the shade of solar panels. In reality, neither solar or wind power overcomes the cost, pollution, and energy used in manufacture. Those costs are carried by others, mostly China.
As the turbine blades and panels age and reach end of life, or break, they create toxic junk that has to be dealt with. Those batteries needed to store energy have a finite lifespan, after which they need to be replaced. Where do they go? to the third world where some poor mook busts them apart with a hammer and takes them apart in a field, gathering the good parts, and chucking the unsaleable toxic stuff in a pile.
Same thing happens in the business world, like with OpenText. The IT knackers will come and bust the carcass up. Keep the good bits and chunk the bad bits in the furnace.
