By the way, thank you to the electronics industry for having succeeded in producing what environmentalists concerned with energy savings have dreamed of, these LEDs which have divided by 7 the energy consumed for lighting, compared to lamps. filamentous.
The first LEDs in the visible, red, it was in the 60s, and far too weak for lighting. It took 50 years to get very bright white ones.
It takes technologies to advance technologies, it takes work, it is a synergy of all academic and industrial sectors that advances surely but slowly.
It is not by decreeing that we need less polluting energy, that we will have it. It is not by banning the heat engine of cars that we will have such an effective alternative.
Progress cannot be made by forced march with a yakafaira otherwise we tax or keskonattendpour otherwise we forbid. These recurring requirements in ecologism are the lot of useless ignorant people who have never put their hands in the dough and of pretentious incompetents who believe themselves to be the only ones with concern for ecology. However, it is not them but the traditional industry that made the LEDs. If they produced as much innovation as they produced vituperation, we would not even know what clean energy to use, so much we would be spoiled for choice.
