Term | Definition |
---|---|
Windiest Areas | Band from NW Texas up through KS, NE, and Dakotas |
transmission grid in US | Texas has only small interchanges, luckily N Tex is in East Interchange |
US Electricity Markets | Some utilities cross state lines, often vertically integrated |
Non-utility purchasers of wind power | tech companies like google, apple, facebook |
Wind project timeline | 3-4 years (can be longer), first assess wind, then locations, licensing, PPA negotiation, engineering, transmission, construction |
Distribution used for wind estimate | Weibull distribution, slightly skewed right because cuts off at zero |
wind power curve | starts around 3 m/s, peaks out around 10 m/s, eventually peaks |
Wind Generation losses | wake effect, availability/maintenance, electrical losses, turbine efficiency, birds |
US wind + solar power capacity additions in history | peaks when credits are about to expire, wind built up beginning 2006ish, solar buildup 2008ish |
Wind and solar LCOE change over time | 2009ish solar like 350 and wind 150, currently both ~40 but wind wider range |
world generation source changes | coal falling in much of the world besides asia, natural gas growing along with renewable |
