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.
For calendar year 2016, wind power in the United States amounted to 226.5 terawatt-hours, or 5.55% of all generated electrical energy. As of January 2017, the U.S. nameplate generating capacity for wind power was 82,183 megawatts (MW). This capacity is exceeded only by China and the European Union. Thus far, wind power's largest growth in capacity was in 2012, when 11,895 MW of wind power was installed, representing 26.5% of new power capacity.
