Electricity generated from the system is a saving, as this amount of electricity is not going to be purchased from the utility company (or, if it’s a grid-connected system, electricity can be sold back to the utility company). How do you compute the annual dollar amount of the saving? Do the panels decline in efficiency each year?

If we wanted to supply all the electricity needs for New York City (NYC), with a popula- tion of about 10 million people, using photovoltaics technology, how much land area would we need? What other elements would be required for such an idea to work for NYC? How large of an investment would this involve, and how would the price of electricity in ¢ per kWeh have to increase in order to recover that investment in 10 years at an interest rate of 8%? For comparison, the average New Yorker paid 12¢/kWeh in 2002.

You want to heat a house on a very cold day as shown in the figure. To do this, you want to use photovoltaic panels as an energy source. It would be about using 15 panels each with an area of 1.5 m2. These panels would be connected to an electrical resistance that would heat the house as shown in the figure. The house is losing heat through the walls and ceiling as shown in the figure. The panels are receiving solar radiation at a rate of 800 W / m2 and if their efficiency is 15%. How much will the temperature of the house rise after an hour? The house is hermetically sealed. Assume that the specific heats of air, cv and cp, are constant as shown in the figure. sol = sun fuga = leakage aire = air
The wind velocity on the upstream side of a wind turbine is 4 m/s. If the turbine extracts 26% of the available kinetic energy, what is the wind velocity on the downstream side of the turbine in m/s? Please include one decimal place in your answer.
How many Btu of heat can be produced by 4 kWh ofelectricity?
In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .
