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 average onshore wind turbine with a capacity of 2.5â3 MW can produce more than 6 million kWh in a year â enough to supply 1,500 average EU households with electricity. An average offshore wind turbine of 3.6 MW can power more than 3,312 average EU households. In 1985, wind turbines were under 1 MW with rotor diameters of around 15 metres. In 2012, the average size is 2.5 MW with rotor diameters of 100 metres. 7.5 MW turbines are the largest today with blades about 60 metres long â over half the length of a rotor diameter of over 120 metres â longer than a football field.
