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.
In 2012, 1,662 turbines at 55 offshore wind farms in 10 European countries produced 18 TWh, enough to power almost five million households. As of August 2013 the London Array in the United Kingdom is the largest offshore wind farm in the world at 630 MW.
