A challenge 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 32.6% capacity for 1.00 year, how much energy does the wind turbine generate?

A challenge 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 32.6% capacity for 1.00 year, how much energy does the wind turbine generate?

32.6% of 1.4 Mw

= (0.326) x (1,400,000 joules/second)

= 456,400 joules/second.

1 year

= (365 da) x (86,400 sec/da) = 31,536,000 seconds

(456,000 joules/sec) x (31,536,000 sec) = 1.438 x 10¹³ Joules

(That's 1.438 x 10⁷ Megajoules, or 3,994,560 kWh)
