According to a study carried out in the United States by the local Department of Energy (DOE), the 49 million LED light bulbs already installed helped save a massive $675 million (over 500 million euros) in a single year.
But wait, there is more as if all light bulbs in the United States were replaced by such bulbs, the potential savings could be the absolutely huge amount of $37 billion (27 billion euros) per year !
This would half the amount of energy consumed for lightning in the US. Now let’s imagine what this would lead in terms of decreased greenhouse gases emissions in the United States alone.
