Financial information on industrial wind turbines
Author: Swanson, Janna
Dear —— Usually these turbines are pushed through for two reasons – money and lowering emissions. The money is a little different in every area and the utility companies play it all close to the chest but this is what we have gathered. In Iowa MidAmerican has freely admitted that they will receive $10 billion in tax credits. They have built 2200 turbines all told so that averages out to $4,500,000 per turbine in tax credits alone. They get to . . .

Author: Miller, Lee; and Keith, David
Highlights Wind power reduces emissions while causing climatic impacts such as warmer temperatures Warming effect strongest at night when temperatures increase with height Nighttime warming effect observed at 28 operational US wind farms Wind’s warming can exceed avoided warming from reduced emissions for a century Summary We find that generating today’s US electricity demand (0.5 TWe) with wind power would warm Continental US surface temperatures by 0.24°C. Warming arises, in part, from turbines redistributing heat by mixing the boundary layer. . . .

Author: Sepulveda, Nestor; et al.
Highlights Firm low-carbon resources [e.g., nuclear, natural gas with carbon capture and sequestration, and bioenergy] consistently lower decarbonized electricity system costs Availability of firm low-carbon resources reduces costs 10%–62% in zero-CO₂ cases Without these resources, electricity costs rise rapidly as CO₂ limits near zero Batteries and demand flexibility do not substitute for firm low-carbon resources Summary We investigate the role of firm low-carbon resources in decarbonizing power generation in combination with variable renewable resources, battery energy storage, demand flexibility, and . . .
More »Marginal Emissions Factors for Electricity Generation in the Midcontinent ISO
Author: Thind, Maninder; et al.
Abstract. Environmental consequences of electricity generation are often determined using average emission factors. However, as different interventions are incrementally pursued in electricity systems, the resulting marginal change in emissions may differ from what one would predict based on system-average conditions. Here, we estimate average emission factors and marginal emission factors for CO₂, SO₂, and NOx from fossil and nonfossil generators in the Midcontinent Independent System Operator (MISO) region during years 2007–2016. We analyze multiple spatial scales (all MISO; each of . . .
