22. Fundamental characteristics of energy are reflected in the first and second laws of thermodynamics (energy laws). Define these two laws. 23. Explain the merits of micropower. 24. The two countries of Botkinlandia and Kellertopia share one single power plant with a maximum capacity of 10 gigawatts (10 billion watts = 10,000,000 kw). Kellertopia is small and prosperous, with a stable population of 500,000 and average energy use of 8 kw per capita. Botkinlandia is larger (pop.=1,000,000), less developed (per capita energy use = 1 kw), and growing fast (population and per capita energy use doubling every 20 years). Instead of building additional power plants, propose population and energy-use goals for both countries that will allow them to manage with the electricity they have. 7
