You install solar power in your home, and the solar panel costs $500 and is capable of producing 3 Million joules of energy each day. If electrical costs are $0.15/kilowatt hour, a kilowatt is equal to 1000 watts, and there are 3600 joules in 1 watt hour, how long will it take for the solar panel to pay for itself in electrical savings?

If the average household in a region consumes about 5,250 kWh of energy per year. In the region, the average annual solar energy potential is about 1,450 kWh/m² per year. If solar panels are available in sizes of 1 m x 1 m with an efficiency of 18 %, how many panels will be needed to power a house? (Since you can't have a fraction of panel, always round up you number to the next integer.) Your Answer: Answer
How much work does a 5000 Watt clothes dryer do when you run it for 30 minutes? 30 minutes = 1,800 seconds.
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.)
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?
Suppose you have a clothes dryer that uses 4000 watts of power and you run it for an average of 1 hour each day. If you pay the utility company 14¢ per kilowatt-hour of electricity, what is the average daily cost to run your dryer? How much would you save in a year if you replaced it with a more efficient model that uses only 2000 watts?
It takes 1 pound of coal to generate one kWh of electricity. How much coal would an average home use in a year? (Hint: 365 days in a year)
Suppose 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?
I have 72 lightbulbs in my house. 53 of these lightbulbs are 65 watt and the other 19 lightbulbs are 53 watt. I use the 65 watt lightbulbs an average of 10 hours a day and 53 watt an average of 12 hours a day. 1 kilowatt=1000 watts. Estimate the energy used during 1 year by all the lightbulbs in my home?
A laptop computer consumes about 40 watts of electricity per hour when operating. At $0.20 per kilowatt-hour, how much does a laptop cost to operate for 10 hours? 40 cents 8 cents 800 cents 200 cents
Assuming that the diet of an average Canadian consists of 2,000 food calories per day (1 food cal≈4200 J), compare the amount of energy consumed by a Canadian family of 4 in one year in their diet with the amount of electrical energy their household consumes, using the average number of about 11,135 kWh. What is the ratio of electrical energy consumption to caloric consumption for this family of 4? (1kWh=3600,000 J). Question 2 options: 4.20 11.14 8.53 3.27
A microwave oven has a power requirement of 1,243 W. A frozen dinner requires 6.5 min to heat on full power. (a) How much electrical energy (in kWh) is used? (b) If the cost of electricity is 14¢ per kWh, how much does it cost to heat the dinner? (Do not round your final answer. Fractional cent values are acceptable.)
In a particular city, electrical energy costs $0.13 per kilowatt-hour. (Round your answers, in dollars, to at least two decimal places.) (a) How much does it cost to operate an old-style incandescent 40.0-W light bulb continuously for 24 hours? How is power related to energy? Be sure to find an energy in units of kilowatt-hours. Then, use it along with the cost rate in dollars per kilowatt-hour to find a cost in dollars. (b) A modern LED light bulb that emits as much visible light as a 40.0-W incandescent only draws 4.50 W of power. How much does it cost to operate this bulb for 24 hours? $ (c) A particular electric oven requires a potential difference of 220 V and draws 20.0 A of current when operating. How much does it cost to operate the oven for 4.80 hours? 2$ Need Help? Read It
