Question

How expensive is it to keep a television on all night long (about 8 hours straight)?

Answer 1

A medium size set will use 600 watts an hour that is about 5 cent per hour.  So around 20 cent for 8 hours.  That is about 5.00 dollars a month on your bill.

These are ruff numbers but not to far off.

Answer 2

A typical 150w tv  is 1.2 kw hr in 8 hrs .that would be 10 to 20    cents
