As blades grow larger, the amount of reinforcement increases in a logarithmic progression. For a 1.5-MW turbine, typical blades should measure 110 ft to 124 ft (34m to 38m) in length, weigh 11,500 lb/5,216 kg and cost roughly $100,000 to $125,000 each.

This cartoon also depicts several other tropospheric gases, including oxygen (O 2), carbon dioxide (CO 2), water vapor (H 2 O), methane (CH 4), sulfur dioxide (SO 2), and carbon monoxide (CO).

Argon is the third most common gas in the Earth's atmosphere, at 0.93% (9,300 ppm), making it approximately 23.7 times as abundant as the next most common atmospheric gas, carbon dioxide (390 ppm), and more than 500 times as abundant as the next most common noble gas, neon (18 ppm).n the universe, argon-36 is by far the most common argon isotope, being the preferred argon isotope produced by stellar nucleosynthesis in supernovas. In addition, argon is the most prevalent of the noble gases in Earth's crust, with the element composing 0.00015% of this crust.
