Table 8.
Range of the share of global electricity consumption, coal production and ammonia production required to fulfill the minimum global human protein requirements, while accounting for 12% food waste. *The share of global coal production required by gasification only includes the coal consumed in the gasification step. The thermal energy requirements of both options and the electricity requirements of the gasification based process are not included here as these could be provided by other technologies.
