Land footprint of solar energy:

(a) In 2016, Arizona’s total annual electricity consumption was 78.05 million MWh. What is this in terms of kWh per day?

(b) Land footprint: The average daily insolation in Phoenix is 5.38 kWh/m2/day. Given this daily energy input, how much land area would you need (in square miles) to generate all of Arizona’s daily electricity from the following types of PV panels:

i. Mono-crystalline Si panels with an efficiency of 22 %?

ii. Thin film CdTe with an efficiency of 12%?

(c) Translate to rooftops: Assuming we use 22% efficient mono-crystalline Si panels, how many rooftops would that take if we put the panels on:

i. Wal-Mart stores with an average size of 102,000 square feet?

ii. Household rooftops with an average size of 2,000 square feet?

(d) Reflection: These types of crude statistics get used all the time in public debates about solar energy. Do you think they’re useful? Why or why not? Take about 3-4 sentences to explain what we learn from this exercise and whether you think it’s useful for talking about solar energy.

Expert Solution

(Note: Part d is my personal analysis of statistical data obtained from the problem, Student must write it's own original thought.)

Solar electricity cost. Despite all the advantages of using solar cells to harvest solar energy, solar electricity still has an insignificant share (~1%) in the world’s overall energy supply picture. This is mostly due to the economic consideration. While there’s virtually no fuel (sunlight) cost and maintenance cost once the solar panels are installed, the initial cost of solar electricity systems is still the obstacle for wide-spread adoption of solar photovoltaic technologies. a. Use the single-crystalline Si solar panels as...

The annual electricity production/consumption for the GRU (Gainesville Regional Utility) territory is about 1.9 million MWh/yr. Let’s assume that we can implement a significant energy efficiency program that can decrease the electricity consumption by 20%. It is also known that GRU has a 102.5 MW biomass power plant. With these facts and assumptions and your knowledge of solar energy, what size of PV array (in MW’s) needs to be installed for GRU to be 100% renewable powered for its annual...

Wind and solar energy are “clean” ways to generate electricity, although we tend to forget about pollution created in the production and disposal of equipment and we may overestimate their value due to grid - related requirements . Discuss both factors and how we might structure policies that would lead to efficient investment decisions.. (An answer would discuss the intermittency of these power sources and the need for (ii) more expensive transmission systems ; (iii)) need for more back -...

According to the International Atomic Energy Agency, per capita electricity consumption in Canada was 16,939 kWh in 2002. A random sample of 51 households was monitored for one year to determine electricity usage. If the population standard deviation of annual usage is 3,500 kWh, what is the probability that the sample mean will be each of the following? a.More than 18,000 kWh b.More than 17,500 kWh c.Between 17,000 kWh and 18,000 kWh d.Less than 16,000 kWh e.Less than 15,000 kWh

US government website says the following interesting information: In 2017, the average annual electricity consumption for a U.S. residential utility customer was 10,399 kilowatthours (kWh), an average of 867 kWh per month. Louisiana had the highest annual electricity consumption at 14,242 kWh per residential customer, and Hawaii had the lowest at 6,074 kWh per residential customer. Let us compute the electricity usage and the bill for last month by asking a few questions to a homeowner. Here are the input...
