Turning Megawatts to negawatts
Do you know that .....
"Due to intrinsic inefficiencies, 33units of energy consumed at the point of use required 100 unit sof primary energy."
To summarize, the efficiency of energy start from coal mining, generation , transmission and up to your home is just about 33% only. There is so many energy waste along the process.
Now i am totally agreed that using gas stoved to cook our meal (direct heat from the fuel) is much more energy efficient than using electric hot plate..
For further details, pls do read the following article from Schneider Electric..
