Hair dryers are notoriously energy hungry, so surely shorter hair that is quicker to dry could reduce carbon without changing your lifestyle…
Through laziness, I had become ‘the one with the long hair’. This is an acceptable and safe description, and through fear of ending up with a worse descriptive characteristic, I’d stuck with it for my entire life so far. But I wanted to know how much extra carbon my hair costs. I use a hair dryer on work days, so I cut half of it off to see if I use half the energy.
Pre-haircut hairdrying would take 4.5 minutes.
Post-haircut hairdrying takes 1.5 minutes.
Hairdryer is 2 kW
Average UK grid electricity for 2013 was 0.44548 kg CO2e/kWh
Energy saving is 0.1 kWh per use (2 kW for 0.05 hours (3 minutes))
I dry my hair every other day, which adds up to 18.25 kWh/yearGiving a grand total of 8.1 kg CO2e saving per year.
It’s not exactly going to save the world as we know it, but it is a reduction for no effort whatsoever. Although, losing all my powers may be a price too far!
