A 2.0 m2 solar panel is fully illuminated by sunlight. Assume the sunlight has a power density of 0.10 J/cm2 -s. a) If the efficiency of the solar panel is 16%, how much electrical energy will it deliver in one hour? b) If this energy is stored in a battery, how long will it keep a 100 W incandescent lightbulb burning if the bulb has an efficiency of 2.6%. (Efficiency of the lightbulb is the light out - - 100 W - to the electrical power in.)
I often make tea in my microwave oven. I know that it takes two minutes to bring the temperature of a cup of water from room temperature to just about boiling: ready for the teabag. I looked up the characteristics of a microwave oven. Typically their power rating is about 1000 W, but I know that this is the power consumed from the power company, not the power delivered to the water. I looked up the efficiency of microwave ovens, and found that it is about 64%, meaning that a typical oven delivers 640 W to the water. I also looked up the frequency of the microwaves that an oven uses, and found thatf= 2,450 MHz. (a) How much energy is delivered to the water in the making of a cup of tea? (b) What is the wavelength of the microwave? (c) What is the energy of one microwave photon? (d) How many microwave photons are absorbed by the water in making a cup of tea?
A hot water heater in a residential home runs for an average of 3.2 hours per day with a heat energy input of 3.7 kW. What would be the annual cost for hot water in this home using a gas hot water heater if the cost of natural gas is $0.33/m3? The gas water heater can get 23 MJ of energy from 1 m3 of natural gas.

(1) An incandescent light bulb produces 5.85 Joules of light energy each second. This bulb is 7.80% efficient, meaning that only 7.80% the total energy it consumes becomes light and the rest becomes waste heat. A 12.0 W fluorescent bulb is designed to produce the same illumination (in Joules of light energy per second) as the incandescent bulb. A large building uses 17,530 light bulbs. At a cost of 8.56€/kW-hr for electricity, how much money will the owners of the building save each year if they use fluorescent bulbs instead of incandescent bulbs? Express your answer in dollars.

Solar panels are rated by their theoretical maximum output capacity. A 2-kW PV panel would theoretically produce 2 kW of electricity at its maximum output (during peak solar radiance).

The “Energy Guide” label on a washing machine indicates that the washer will use $85 worth of hot water per year if the water is heated by an electric water heater at an electricity rate of $0.113/kWh.
