  • A watt hour is equal to 0.86 nutritional calories. My estimate of 40 watt hours per mile converts to about 35 kcal. Estimates of the energy taken to pedal a bike are about 30-40 kcal/mile. That checks out!

    1 kilowatt hour is equivalent to 860 kcal.

    1 kilowatt hour from a coal power plant generates about 1.0-1.1 kg of CO2.

    For a typical Western diet, studies suggest that the average emissions associated with food production and transportation can range from about 0.5 to 2.5 kg of CO2 per 1,000 kcal of food consumed. (0.4-2.1 kg of CO2 per 860 kcal)

    The ebike generally has a smaller environmental footprint than the analog bike, as most sources of power produce less CO2 than coal power plants and most people eat more meat than necessary, putting them in the higher range of the food CO2 production range.

    I’m sure this will draw some criticism but I’ve found duck.ai to be extremely helpful in troubleshooting minor issues with my Linux mint installation and recently with accessing and understanding SMART hard drive diagnostic data. It’s very helpful in figuring out which commands could be useful in the terminal and in understanding exactly what each terminal command is doing. Of course finding answers in forums and manuals is still relevant and important but as a beginner, this has been a fast and easy way to get advice.
