Achallenge gaining prominence throughout the planet is the increased need for "green" or sustainable energy. in certain parts of the country, wind farms are a viable alternative to conventional energy sources. an average wind turbine (the device which converts rotational motion to electricity) has a maximum capacity of 1.40 mw. however, realistically the wind turbine never runs at full power. if a wind turbine runs at 28.8% capacity for 1.00 year, how much energy does the wind turbine generate? number e- kwh an average american household consumes 1.00 x 10t kwh in 1.00 year. how many houses can the one wind turbine power? o 0.00283 o 3.53 x10 number of houses- 353 o 100

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
