Potential chemical weapons from living organisms. Toxins are effective and specific poisons produced by living organisms. They usually consist of an amino acid chain which can vary in molecular weight between a couple of hundred (peptides) and one hundred thousand (proteins).
1 NREL previously calculated wind farm land usage at about 85 acres per MW of capacity and capacity density of 3.0 Â±1.7 MW/km 2. 2  Yale calculated wind energy usage down to the turbine level, calculating 1-3 acres per turbine.
An August 2009 study for the National Renewable Energy Laboratory examined land-use data for 172 projects, representing about 80% of the installed and targeted wind capacity in the U.S., and found an average area of 85 acres/MW.
