Total wind power capacity in the United States in 2000 was about 2540 MW. By 2015, the total wind power capacity in the United States was about 72,500 MW. Calculate the percent change in the total wind power capacity in the United States from 2000 to 2015. Show your work.
Total wind power capacity in the United States in 2000 was about 2540 MW. By 2015, the total wind power capacity in the United States was about 72,500 MW. Calculate the percent change in the total wind power capacity in the United States from 2000 to 2015. Show your work.(d) A wind turbine has a capacity of 3 MW. Assuming the turbine operates at 50 percent of its capacity all day and every day for a week, calculate how many kWh of electricity the wind turbine will produce by the end of the week. Show your work.
(e) If a typical house uses 10,900 kWh per year, calculate how many houses could have their full energy needs provided for one year by the turbine above if it continued to operate as described for one year. Show your work.
The percent change in wind power capacity in the U.S. from 2000 to 2015 is approximately 27,543.31%. A 3 MW wind turbine operating at 50% capacity continuously for a week would produce 252,000 kWh. If it operated like this for an entire year, it could power approximately 1,202 houses.To calculate the percent change in the total wind power capacity in the United States from 2000 to 2015, use the following formula:Percent Change = ((Final Value - Initial Value) / Initial Value) * 100Inserting the given values, we get:Percent Change = ((72,500 MW - 2,540 MW) / 2,540 MW) * 100Percent Change = (69,960 MW / 2,540 MW) * 100Percent Change = 27,543.31%Calculating Electricity ProductionA wind turbine with a capacity of 3 MW operating at 50 percent capacity all day for a week would produce:Electricity (kWh) = Capacity (MW) * Capacity Factor * HoursElectricity (kWh) = 3 MW * 0.50 * (24 hours * 7 days)Electricity (kWh) = 1.5 MW * 168 hoursElectricity (kWh) = 252,000 kWhCalculating Houses Powered for a YearNumber of houses powered = Total Annual Production / Annual Consumption per HouseConsidering the turbine operates as described for one year:Total Annual Production = 252,000 kWh/week * 52 weeksTotal Annual Production = 13,104,000 kWh/yearNumber of houses powered = 13,104,000 kWh/year / 10,900 kWh/year/houseNumber of houses powered = approximately 1202 houses...
