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).

The most abundant gases found in our atmosphere are nitrogen and oxygen. Nitrogen makes up around 78% of the total atmosphere, while oxygen makes up 21%. The remaining 1% is made up mostly of a gas called argon.xygen is the most important of the gases in our atmosphere in relation to animal life. Almost all animals use oxygen as a critical ingredient for the processes of life. Without it, each of us and most of the animals on Earth would perish in a matter of just a few minutes.
