1 Explain that a population pyramid shows the age and sex structure of a population. 2  Point to the horizontal bars, which show the percentage (or the absolute number) of males and females in each age group. 3  Have students interpret the chart.
1 A small-to medium-capacity dehumidifier (11-25 pints) for a living room can run around $100-$250 or more, depending on size and features such as a humidistat to set the desired humidity, auto-shut-off when the tank's full, energy efficiency and quiet operation.
=$102.2/per year. This method will only give you a rough estimate of how much a dehumidifier energy cost will be. There are many other factors that come into play other than strictly the dehumidifier energy usage per hour. For example, a very efficient unit compared to one that barely removes humidity.f using a desiccant one the answer is yes; however, many units, such as the Energy Star ones, cost quite little to operate. The dehumidifier energy cost will vary depending how much humidity you have and how big an area is. For a typical basement, you can expect to pay around $15-25 per month.
