Question

Table 2.1: Estimated average power used per person as a function of the stage of human development (worldwide) or as a function of year (for the United States, 1850-2000). The power values are calculated from the primary energy use. society power consumption (W) hunter 100 use of fire 200 domestication of animals 500 Renaissance 1160 1850 4880 1900 5340 1950 7300 1960 8180 1970 11,000 1980 1990 11,000 2000 11,730 Based on data from G.J.

Answer 1

I Calorie perday = 4.84259 x 10 watts. (1 given, A person consumes 2000 calorie (day which is equal to 2000 & 6184259x105 = 0.096518 watts. By considering the latest average power consumption per person per year from Table 2.1 for yr 2000 – 11,730 watts. Pern Tractor 365 X0.096518 : 11730 35.22907 : 11730 1:332.96 (i) Comparing and Considering the data from Table 21 and 243, for yr 2000 – 11,730 watts / person/ur. Total energy production per year from hydron electricity = 2,45% = 2.45 11.730 Mascal e 100 => 287.385 watts / person (yeal.

The total hydroenergy per year can only be estimated per person.. please do note it.
