Let me guess: you don&#x27;t live in Bangladesh. Where there are ~160 million people, and the country is just one big flood plain. Bangladesh already has the highest population density of any &quot;big&quot; country, and the sea is eating away at the land.<p>If $0.30&#x2F;kWh is the real price of electricity after externalities have been added in, then so be it. Because the alternative is too awful to imagine.<p>Also you&#x27;ve forgotten to include in your calculations that Costa Ricans probably <i>use</i> a lot less electricity than Americans. Someone earning $6k.pa probably does not have AC, a huge refrigerator, etc.
