How big are the energy savings worldwide if everyone uses LED instead of regular lamps?
In: 4
A lot
Start with just the US. A 100W equivalent LED bulb uses 10W so that’s a 90% savings
Say there are 100 million homes, each with 10 60W bulbs that are on 6 hours per day. The incandescent bulbs would consume 131,400 GWh per year. LED bulbs would only consume 13,140 GWh per year
Now for scale, the biggest nuclear power plant in the US makes 31,000 GWh/year, the biggest Dam is at 21,000 GWh/year, and the biggest coal plant makes 18,000 GWh/year
Saving 118,000 GWh/year allows for the shutdown of *at least* 6 coal plants but likely closer to 20 older smaller lower efficiency ones since the really big ones are actually a lot cleaner and cost effective than the older smaller ones
