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 electricity needs? Show all work and discuss the limitations of this approach.

The US generates ∼ 4,000 million megawatthours (MWh) of electricity per year (source: DOE1 ). Note: a MWh has units of power × time, or energy. Assume that the demand for this energy is constant over the course of the day and year. Imagine building an array of solar panels in the desert in the Southwest. Allowing for night and day, sunlight will shine on the panels for 12 h per day. Electricity generated during the day will be stored...

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...

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...

You are the Finance Director of a regional health authority. Currently the authority caters for about 100,000 residents, with an annual budget of $10 million. The region is experiencing rapid population growth, and you expect to have to look after 110,000 residents next year. You have just been told that your budget will be $10.5 million. Since you used to have $100 per resident, but now will have to work with $95.45 per resident, can you say with justification that...

A company plans to invest for a production plant. Annual production plan is 50 million units. The investment at time 0 that is required for building the manufacturing plant is estimated as $600 million, and the economic life of the project is assumed to be 11 years. The annual total operating expenses, including manufacturing costs and overheads, are estimated as $125 million. The salvage value that can be realized from the project is estimated as $90 million. If the company’s...

There are about 18 million households in the US that self-identify as Hispanic and have annual income below $100 000. Aaron and Sophie disagree about what fraction of this population has average family income below about $50 000. Aaron thinks about 50% of this population has average family income below about $50 000. Sophie thinks Aaron’s fraction is just wrong. They agree to hypothesis test Aaron’s estimate at level of significance 0.01, using the following annual income estimates from a...

The IHateToLose Company has annual sales of $100 million. Its only production plant is valued at $50 million. There is a 1% chance of an industrial accident that would completely destroy the plant, resulting in a total loss. Partial losses do not occur. The annual premium to insure the plant with a limit of $50 million (and no deductible) would be $1,000,000. a) Would management of the IHateToLose Company choose to insure or retain the plant accident risk under the...
