Energy balance for a climate-neutral country Start from the energy balance described in Table 15.1..


Energy weigh for a sphere-negative empire Start from the life weigh descriptive in Table 15.1 (Exercise 15.7). Construct an life weigh for the year 2040 for a situation in which this empire should be entirely sphere negative. Postulate an activity growth objurgate of 2 per cent per year, and an firm objurgate of life willingness increase of 2.5 per cent per year. In abstracted, postulate that 2/3 of the fossil fuel use in enravishment is replaced by electricity (substitution objurgate 1 to 0.4) and the pause by biofuels. Postulate that all original gas use in households and services is replaced by electricity (adherence objurgate 1 to 0.25). Postulate that half of the fuel used in activity is replaced by hydrogen, the pause is replaced by biofuels. All the hydrogen is executed out of electricity after a while a transmutation willingness of 80 per cent. Twenty per cent of electricity is executed out of nuclear life and 80 per cent from hydro, solar, and twist. Production of automotive biofuels out of principal biomass has a transmutation willingness of 80 per cent. Tip: fashion abstractedal columns and rows in the life weigh to grasp into recital abstractedal life carriers and transmutation processes.
