GGR333H5 Lecture Notes - Lecture 9: Diminishing Returns, Wind Turbine
Document Summary
Pros: no emissions, short construction times, small individual units, cheaper than solar, can be tailored to specific uses and locations, complement to radiant solar (days with little sun usually have better than average winds) Cons: intermittence (no steady supply, unpredictability (can it ever be forecasted?, variability (not constant when there) All of these points are highly problematic in a (cid:498)grid(cid:499) context: best locations often remote from markets (transportation costs & Other issues: power loss: timing: supply often doesn"t match demand, comparatively small amount of energy/volume, wind force within right parameters, not. Too strong (wind turbine shuts down or grid overloads: therefore, the few areas that have the best wind conditions must be developed extensively. Most wd wind power output: is surplus to demand at moment of generation. Denmark generates a lot of wind energy at a given time integrity to the danish energy grid: exported (norway, sweden, germany) at reduced prices to preserve.
