21.1 Table 21.1 shows the total area, sun hours per day and energy consumption of five different countries. (a) If a PV system of 270W, is installed in each of these locations, in which country would it be best to place the panels to obtain the maximum output?

How much area, as a percentage of the total area of the US, would be needed to cover the total annual energy demand of the country with solar panels having an efficiency of 15%? (c) Which of the five countries would need to cover the highest percentage of their area with solar panels to supply all their electricity demand with solar energy? (d) Which of the five countries would need to cover the lowest percentage of their area with solar panels to supply all their electricity demand with solar energy?

(B) What are two problems with using this rotation age to manage forest lands? CI Will this rotation age be longer or shorter than the rotation age that makimizes the present value of the total timber income over multiple rotations? Why?

A competitive industry has production processes that generate pollution. okay with studies carried out on the affected population, the marginal costs associated with contamination are constant and 500 u.m. for each unit of the good produced. These costs are associated with lost working days, illness treatment costs and the nuisance generated in the population. Currently the production level of the industry is 250 units and the market price is 1500 (um/unit). Market studies carried out by the firms estimate that if the price rises at 1,800 (mu/unit) the quantity demanded would drop to 200 units and the marginal cost of production of each firm at this new production level is 1,300 (m.u./unit). assume linearity in market demand and in the marginal costs of production of the firms. Graph to justify your answers. b)Graphically indicate and determine the magnitude of the social cost of the situation with a production level of 250 units.
