The amount of energy saved by using a clothesline instead of an electric dryer can vary depending on various factors such as the efficiency of the dryer, the climate conditions, and personal preferences. However, I can provide you with a general estimate.
On average, electric dryers consume around 2,000 to 5,000 watts of electricity per hour of operation. Let's assume an average dryer with a power rating of 3,000 watts. If you typically run the dryer for one hour per load and use it for, let's say, 100 loads in a year, that would be equivalent to 300,000 watt-hours or 300 kilowatt-hours (kWh) of electricity.
By contrast, using a clothesline to dry your clothes relies on natural air and sunlight, which requires no electricity. Therefore, the energy savings would be equal to the amount of energy the electric dryer would have consumed.
Keep in mind that this is a simplified estimate, and actual energy savings can vary depending on factors like the size of the load, the drying time required, and the local climate conditions. Additionally, using a clothesline may not be feasible in certain weather conditions or living situations, so it's essential to consider practicality and personal circumstances when making choices about energy usage.
