Chapter 1, Problem 43P
The average American uses electrical energy at the rate of about 1.5 kilowatts (kW). Solar energy reaches Earth’s surface at an average rate of about 300 watts on every square meter (a value that accounts for night and clouds). What fraction of the United States’ land area would have to be covered with 20% efficient solar cells to provide all of our electrical energy?

- A kilowatt-hour (kWh) is a unit of measure equal to one thousand watts of electricity being used in one hour. Power companies use this measurement to determine your home energy bill. Consider using a bike for power: It takes 6 minutes pedalling at 24-26 volts consistently to produce just 1/10 (0.1) of a kWh. An average home uses about 25 kWh a day. How long would someone have to pedal at 24-26 Volts to power an average home?arrow_forwardAccording to the World Energy Council, the average household in Mexico consumes about 1600 kWh of energy per year. In Monterrey, Nuevo León, Mexico, the GHI Solar Map suggests that the average annual solar energy potential is about 1800 kWh/m2 per year. If solar panels are available in sizes of 1 m × 1 m with an efficiency of 17%, how many panels will be needed to power a house in Monterrey for a year? Question 10 options: 6 7 2 1arrow_forwardSuppose a person eats 2000 Kcal per day. Using the facts that 1 Kcal is approximately 4.2 Kj (a kilojoule is a unit of energy equal to 1000 joules) and 1 watt is one joule per second (a unit of power), about how many watts does a person use?arrow_forward
- If you have an average of 6.5 hours of online class per day for 204 days of school per year, how many kilowatt-hours are consumed and what is the annual cost of using your laptop if the estimated cost per hour of a laptopis P0.75 / kWh? (base this, a regular laptop uses 90 Watts.)arrow_forwardHow much land (in km2) would you need to cover with solar panels in order to generate all of our power from solar energy? Assume human power consumption is 15 TW. If one takes into account the day-night cycle and occasional cloudiness, solar panels receive on average about 200W/m2 of sunlight. And this is further reduced because those panels convert sunlight into electricity with an efficiency of about 20%.arrow_forwardElectric utility companies generally say that a community with 65,000 homes needs to be served by a 100 MegaWatt facility (keep this fact in mind as you work through this assignment: 100 MW = 65,000 homes!) The fossil-fuel burning Mountainview generating station near us provides electricity to 715,000 homes. A Google search of "mountainview generation station" shows that it provides MW of power.

If the average rate of energy consumed by the house was instead diverted to lift a 1.80×103 kg car 11.3 m into the air, how long would it take? 1. car: ______ seconds? Using the same rate of energy consumption, how long would it take to lift a loaded Boeing 747 airplane, with a mass of 4.10×105 kg, to a cruising altitude of 9.92 km? 2. airplane: ______ seconds?arrow_forwardHow much efficiency would a solar panel of surface area A = 2 m² need to have to generate 1.7 kWh of electricity in a region where the solar power density is 4.5 kWh/m2/day? Write the efficiency in decimal value rounded off to 2 decimal places, not as a percentage. For instance you would write 0.25 and not 25%.arrow_forward
- At a certain location, the solar power per unit area reaching Earth’s surface is 200 W/m2, averaged over a 24-hour day. If the average power requirement in your home is 3 kW and you can convert solar power to electric power with 10% efficiency, how large a collector area will you need to meet all your household energy requirements from solar energy? (Will a collector fit in your yard or on your roof?)arrow_forwardA certain region currently has wind farms capable of generating 2,400 megawatts (2.4 gigawatts) of power. A. Assuming wind farms typically generate 35% of their capacity, how much energy in kilowatt-hours, can the region's wind farms generate in one year? Given that the average household in the region uses about 10,000 kilowatt-hours of energy each year, how many houses can be powered by these wind farms? B. One of the great advantages of wind power is that it does not produce the carbon dioxide emissions that contribute to global warming. On average, the energy produced from fossil fuels generates 1.5 pounds of carbon dioxide for every kilowatt-hour of energy. Suppose the region did not have its wind farms and the energy was instead produced from fossil fuels. How much more carbon dioxide would be entering the atmosphere each year in pounds?arrow_forwardThe sun doesn't shine as brightly in winter as it does in summer. This means that in winter you won't generate enough to fulfil your energy needs whilst you have a surplus of energy in summer. It is therefore necessary to place a battery in your house to store the extra energy. If we assume that we generate 66% of our total energy in the months April to September and that we use equal amounts of energy throughout the year. Question: How much electricity must we store over these 6 months to use in the other half of the year? Give your answer in 3 significant figures (link). Remember we use 2990 kWh of electricity per year. Write down your answer as you need it for the next question Solution: kWharrow_forward
