4 Calculation of the amount of solar energy Reference World primary energy supply is about 1.5 toe/year par capita 1.5 [toe/ year par capita] = [kcal/day par capita] Human need energy of 2 [kcal/day par capita] to live. Solar energy flowing into the earth.7 πr 2 [m 2 ] 1367 [J/m 2 s] = [m 2 ] 1367 [J/m 2 s] = [J/s] = [kcal/s] (= 4 [kcal/day par capita]) =2.94[Mtoe/s] (=1.5 4 [toe/year par capita]) We have not used it since fossil fuels were cheap! Studentʼs Presentation at Nov. 28 Consider effective policy to reduce worldʼs fossil fuel consumption by using statistics like todayʼs lecture or following website first. Then, show your assumption about technological development such as electric vehicle, and introducing schedule of the technologies to our society. Evaluate the long term effect of the technologies on the reduction of fossil fuel consumption till 25 quantitatively based on your assumption. Running Resistance of the Automobile Rolling Air Acceleration Gradient About 75% of the running resistance is proportional to vehicle weight 3% improvement in fuel efficiency is expected by % weight reduction In the case of electric vehicles, the heavy and expensive battery can be reduced in proportion to the weight reduction of vehicle body Energy Consumption (MJ) EV reduces oil consumption drastically, but Gasoline Electricity Gasoline Hybrid weight without battery : 85kg average daily trip distance : 25.4km Secondary Battery (kwh) Electric There is an optimal amount of secondary battery depends on the weight of vehicle and average daily trip distance. Hence, weight lightening of HEV (Hybrid EV) is effective to reduce cost of the optimal HEV, accordingly, its early spread. In addition, the daily demand of 4kWh, which is generated by 6m 2 of photovoltaic, can also be reduced by vehicle's weight reduction.
