A typical American household uses 26.5 kW-hour of electricity per day, and that electricity is mostly supplied by fossil fuels. If we wanted to instead power a house by solar panels, which receive on average 370 W/m2 from the Sun each day and are 15.7% efficient (fraction of solar energy converted into useable electrical energy), what area of solar panels is needed to power an average American home?

Solutions

Expert Solution

Total energy requirement for a typical American household is = 26.5 kW-hour per day

Energy receivd by solar panels per m2 per day is

Solar Energy converted into electrical energy per m2 per day is

To get the required area of solar panel we have to divide the required energy to the converted energy so

So the required Area of solar panels to power an average American home is 19.00786 m2

A typical frostless refrigerator uses 655 kWh of energy per year in the form of electricity. Suppose that all of this electricity is generated at a power plant that burns coal containing 3.5% sulfur by mass and that all of the sulfur is emitted as SO2when the coal is burned. Part A If all of the SO2 goes on to react with rainwater to form H2SO4, what mass of H2SO4 is produced by the annual operation of the refrigerator? (Hint:...

Consultants in a particular industry are currently paid $100 per hour and the typical work day lasts 10 hours. Demand for labour in that industry increases, resulting in the average hourly rate increasing to $150 per hour. However, a labour survey reveals that most consultants now work two fewer hours per day than they did prior to the rise in the price of their labour. A newspaper comments that this is at odds with the “law of supply”, such that...

The Al Best Company uses a 7.5-kW motor for 16 hours per day, 5 days per week, 50 weeks per year in its flexible work cell. This motor is 85% efficient, and it is near the end of its useful life. The company is considering buying a new high efficiency motor (91% efficient) to replace the old one instead of buying a standard efficiency motor (86.4% efficient). The high efficiency motor cost €70 more than the standard model, and should...

Suppose that the preferences a typical American has for quantities of electricity (E) and gasoline (G) is given by U(E, G) = αln(E) + (1 − α)ln(G) where 0 < α < 1. Suppose the prices of gasoline and electricity in the units provided are both $1/unit and the consumer has an income of $100. Suppose in addition, the government has chosen to ration electricity by allowing 2 a maximum consumption of 50 units of electricity (E ≤ 50). a....
