Question

3. Americans Love Energy The average power consumption per capita in the United States is 10,000 w. (see https://en wikipedia.org/wiki/List.of.countries.by-energy consumption per capita) a. Roughly how many Joules of energy does an average American consume per year? How many snickers bars does that correspond to? b. Look up the power consumption of an LED lightbulb you can buy on Amazon for your house. If you were to take the power consumption of a single American and use it to power LEDs continuously, how many LEDs could you power? C. If you were to collect 100% of the solar energy hitting a square meter on the surface of the Earth in direct sunlight, you would collect roughly 1000 W. If solar panels were 100% efficient, namely if they could collect all solar energy that falls on them, how many square meters in solar panels would an average American need to provide for all of his energy needs? (Keep in mind that the Sun doesn't shine all the time) d. In reality, solar panels are not 100% efficient. Do an internet search to determine how efficient an average solar panel one might install on a roof of a house would be, and use that efficiency figure to recalculate the answer to part c
