(a) Calculate the power per square meter reaching Earth’s upper atmosphere from the Sun. (Take the power output of the Sun to be 4.00×1026W.) (b) Part of this is absorbed and reflected by the atmosphere, so that a maximum of 1.30 kW/m2 reaches Earth’s surface. Calculate the area in km2 of solar energy collectors needed to replace an electric power plant that generates 750 MW if the collectors convert an average of 2.00% of the maximum power into electricity. (This small conversion efficiency is due to the devices themselves, and the fact that the sun is directly overhead only briefly.) With the same assumptions, what area would be needed to meet the United States’ energy needs (1.05×1020 J)? Australia’s energy needs (5.4×1018 J)? China’s energy needs (6.3×1019 J)? (These energy consumption values are from 2006.)
Discuss what international peace, cooperation, and security have to do with addressing the world’s energy needs.
In Arizona, where there are 316 sunny days per year, it requires 330 acres of land to generate 300 MW of average annual power. If there are only 174 sunny days per year in Pennsylvania, how many acres of land would it require to generate the same average annual power? Please round to the nearest acre. Note: assume that a cloudy day delivers 0 watts/acre of solar power. This is not true, but it simplifies the problem for us.

Assume human power consumption is 15 TW. If one takes into account the day-night cycle and occasional cloudiness, solar panels receive on average about 200W/m2 of sunlight. And this is further reduced because those panels convert sunlight into electricity with an efficiency of about 20%.arrow_forward

This means that in winter you won’t generate enough to fulfil your energy needs whilst you have a surplus of energy in summer. It is therefore necessary to place a battery in your house to store the extra energy. If we assume that we generate 66% of our total energy in the months April to September and that we use equal amounts of energy throughout the year. How much electricity must we store over these 6 months to use in the other half of the year? Give your answer in 3 significant figures.
