Without providing consumption numbers and electric billsand rates, for the typical family that is a pipe dream.
If you and your spouse just live in a one bedroom apartment, have no AIr Conditioning, no electric heat, no washer and dryer, gas on demand hot water, gas cooktop, small fridge freezer, LED lighting, new LED TV and just one computer … then yeah, maybe your electric bill went from $30 to $15. No way you went from $150 to 75, $200 down to $100 or beyond.
Maybe you hit some low use threshold and now pay a lower rate too.
