Can somebody who is an expert in science help me in energy usage?!

I have a few questions regarding energy usage etc..
Can an expert in this area tell me if my calculations make sense?
My electric dryer takes up 5 KWh for each hour of use. My dryer is in use for 2 hours a day, every day. That makes a total of 14 hours a week (including weekends). Multiplying 5 KWh by 14 hours a week I get 70 KWh of energy that is being exerted each week. So, just from air drying my clothes in one week, I save approximately 70 KWh each week? How much energy would I save in one month? Please be detailed in your answers, so I can understand.
