There is also an underlying "energy panic": the idea that the tumble dryer accounts for a large percentage of the total electricity spending. Wrong. Apart from the practical terms, the clothes dry 75% faster in the tumble dryer than outside, there are fewer creases and you may not even have to iron them, thus reducing energy spending by not using the iron. Remember that this does not happen with combo washer dryers, where the clothes come out with many more creases. According to the CFE (the Federal Electricity Commission of Mexico), the electricity required by a dryer is minimal: 139 kWh per year.
