The NOVA program segment can be found at this link:
“Replacing conventional lighting sources with LEDs with an efficiency of 200 lumens per watt would decrease the global electricity consumed for lighting by more than half. That reduction is equal to the electricity created by 230 typical 500-megawatt coal plants and would reduce greenhouse gas emissions by 200 million tons.”
If you believe our Earth is old and will survive a multitude of abuse . . .
. . . think again. So a meteor may have wiped out the dinosaurs plus and life had to start all over again, right? All the survivors had to deal with the mess left behind but managed somehow. How long did that take?
Eventually our world recovered and became beautiful again:
Now we humans have become bad stewards and are messing up this world because of carelessness, greed and laziness. We do not respect much it seems.
