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.
According to these targets, more than 40 GW offshore wind power is expected to be installed across the region by the year 2020. With an average turbine size of about 5-10 MW, between 4000 and 8000 wind turbines need to be transported and installed, operated and maintained. When other international developments are also considered, these numbers are much higher.
