A household uses 1, 100 kilowatt-hours of electricity in one month. After buying new energy-saving appliances, they reduced their use of electricity the next month by 14%.
How many kilowatt-hours of electricity did they use the second month?
The reduction in electricity usage is 14/100 x 1100 = <<14/100*1100=154>>154 kilowatt-hours.
So they used 1100 - 154 = <<1100-154=946>>946 kilowatt-hours in the second month. Answer: \boxed{946}.
