Unless indicated otherwise, documents presented here are not the product of nor are they necessarily endorsed by National Wind Watch. Nor should it be implied that the sources and writers endorse National Wind Watch. These resource documents are shared here to assist anyone wishing to research the issue of industrial wind power and the impacts of its development. The information should be evaluated by each reader to come to their own conclusions about the many areas of debate. • The copyrights reside with the sources indicated. As part of its noncommercial educational effort to present the environmental, social, scientific, and economic issues of large-scale wind power development to a global audience seeking such information, National Wind Watch endeavors to observe “fair use” as provided for in section 107 of U.S. Copyright Law and similar “fair dealing” provisions of the copyright laws of other nations.
Electricity at Any Price? The Real Cost of Wind Power
Author: Fahlén, Per; Henrekson, Magnus; and Nilsson, Mats
This policy brief critically evaluates the current push for extensive wind power expansion in Sweden. This Policy Brief critically examines the economic and technical assumptions behind the rapid expansion of weather-dependent energy sources such as wind and solar, identifying several systemic risks and shortcomings. Key Findings 1. System Stability Risks A high share of intermittent power (currently 25% wind and 2.5% solar) threatens grid reliability. Essential system functions (instantaneous power, frequency control, reactive power, inertia) are inadequately supported by wind . . .

Another version: Breakdown of renewables: Wind energy represented 18% of the energy (not just electricity) produced by renewables, or 1.5 quadrillion BTU. 1 quad = 293 TWh, so 1.5 quads = 439.5 TWh. Total electricity production was 32.09 quads, or 9,402 TWh. Line loss took away 0.61 quads, or 179 TWh, of that. Source: Monthly Energy Review, U.S. Energy Information Administration (EIA)

Author: New York State Energy Research and Development Authority
[from Summary:] Based on the totality of this analysis, this concludes that Great Lakes Wind currently does not offer a unique, critical, or cost-effective contribution toward the achievement of New York State’s Climate Act goals beyond what existing, more cost-competitive programs are currently expected to deliver. This conclusion is based on a fulsome analysis of the resource development costs, ratepayer impacts, expected State benefits, transmission and interconnection limitations, infrastructure and supply chain constraints, visual impacts, and potential environmental impacts of . . .
More »Wind and Solar—The Penetration Problem: The More You Do, The Harder It Gets
Author: Curry, Judith
There seems to be a belief that increasing the level of wind and solar projects will make subsequent progress with these resources easier. Nothing could be further from the truth. Increasing penetration levels of wind and solar is like a Sisyphean task, except that it is worse. The challenge may be better understood as akin to pushing a huge rock which is getting heavier and heavier, up a hill of a steeper and steeper slope while the ground below gets . . .
