Question
Chapter 10, Problem 34E
Interpretation Introduction
Interpretation:
The area of the PV cells required to run the air conditioner is to be determined and some good reasons to use solar power for air conditioning units are to be stated.
Concept Introduction:
Power input on the PV cell is the total active area of the PV cell multiplied by the solar power. The percent of the input power that is converted to output power by a PV cell is called its efficiency. Percent efficiency of a PV cell is

Consider a cloudless day in which the sun shines down across the united states. if 2659 KJ of energy reaches a square meter (m^2) of the united states in one hour, how much total solar energy reaches the entire united states per hour? the entire area of the united states is 9,158.960 km^2.
A number of companies currently lease solar panels to homeowners to offset the home’s energy use. The total energy production of a certain residential solar system in suburban Maryland was 7581.62 kWh over the last calendar year. What mass of carbon dioxide did this solar system keep out of the atmosphere during that time, assuming that the energy consumed by this home would otherwise have been supplied solely by coal-burning power plants (note that this isn’t a great assumption, as Maryland also has a nuclear power plant, solar and wind farms, and Montgomery County incinerates waste to generate electricity)? Keep in mind that power plants are inefficient, and are able to convert on average 33% of the heat generated by the combustion of coal into electricity. Assume that coal can be approximated as C(s) (again, not a great assumption, but sufficient for this problem). Use the following data to find the heat of combustion of coal:
2 C(s) + O2(g) --> 2 CO(g)…

Use the following data to find the heat of combustion of coal: 2 C(s) + O2(g) --> 2 CO(g)…arrow_forwardIn 2008 the approximate energy consumption for the entire population of earth for an entire year was 4.74x10^20 joules. The sun's energy striking the earth is orders of magnitude greater than this...taking the whole surface aea of the earth for an entire year, there is approximately 1.33x 10^16 joules/miles striking the earth's surface per year. if a solar panel was 100% efficient, approximately how big would the surface area (with units of a mile) of the solar panel have to be to meet the energy needs of the people living on earth?arrow_forward
- why is lcoe misleading in the comparison of different energy generation technologiesarrow_forwardThe total power used by humans worldwide is approximately 15 TW (terawatts). Sunlight striking Earth provides 1.336 kW per square meter (assuming no clouds). The surface area of Earth is approximately 197,000,000 square miles. How much of Earth's surface would we need to cover with solar energy collectors to power the planet for use by all humans? Assume that the solar energy collectors can only convert 10 % of the available sunlight into useful power.arrow_forward1. Why is it difficult to implement renewable energy and how to implement it?arrow_forward
- Justify the use of these non renewable resources (metals and fuels) based on their properties.arrow_forwardMuch of the U.S. electricity is generated in thermal generating stations that burn fossil fuels such as coal and natural gas. The use of solar-powered generating stations is expected to increase over the next decade and replace older fossil-fuel generating stations. What impact might this change have on greenhouse gas emissions?arrow_forwardFor similar light intensity, compact fluorescent bulbs use about 25% of the energy of incandescent bulbs. Let's say you replaced a bulb of 100W with a fluorescent bulb and that your utility charges $0.15/kW-hour. How many dollars would you save in electricity in the 10,000-hr. lifetime of the bulb?arrow_forward
- When an electrical appliance whose power usage is X watts is run for Y seconds, it uses X × Y joules of energy. The energy unit used by electrical utilities in their monthly bills is the kilowatt-hour (kWh, that is, 1 kilowatt used for 1 hour). How many joules are there in a kilowatt-hour? If electricity costs $.09 per kilowatt-hour, how much does it cost per megajoule?arrow_forward5Assume that the amount of energy needed to raise the average temperature of the atmosphere by 0.4°C is 2 × 1021J. Estimate how much burned fuel would be needed to give rise to this increase, assuming this were the only cause of changes in the earth's temperature. Hint: Assume that coal has an energy density of 24 megajoules per kilogram.arrow_forwardConsider two coal-fired power plants that generate 5 x 1012 J of electricity daily. Plant A has an overall net efficiency of 38%. Plant B, a proposed replacement, would operate at higher temperatures with an overall net efficiency of 46%. The grade of coal used releases 30 kJ of heat per gram. Assume that coal is pure carbon. a. If 1000 kg of coal costs $30, what is the difference in daily fuel costs for the two plants? b. How many fewer grams of CO2 are emitted daily by Plant B, assuming complete combustion?arrow_forward
