NO, "MOST PLACES" DO NOT. NOT EVEN CLOSE. AND THEY USE DIESEL FUEL TO GENERATE ELECTRICITY ,EINSTEIN....
What are you talking about?
The largest power generating facility in the US is the Grand Coulee Dam in Washington State, and 9 of the top 10 power generating facilities are nuclear powered, not diesel.
If by "diesel" you mean petroleum plants, they only produce 0.4% of the nation's electricity.
Someone lied to you and you were too dumb to know it.
