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?
Their electricity use the second month was 100% - 14% = <<100-14=86>>86% of their electricity use the first month.
This is equal to 86/100 * 1,100 kilowatt-hours = <<86/100*1100=946>>946 kilowatt-hours. Answer: \boxed{946}.
