“…Overall, Figure 4 shows how greater levels of installed wind capacity can, on average, reduce CO 2 from electricity across a wide range of input cost, load, and wind scenarios. This is consistent with previous research that focuses on circumstances in a small number of recent years across a range of countries (Clancy et al, 2015;Amor et al, 2014;Cullen, 2013;Kane et al, 2013;Traber and Kemfert, 2011).…”

“…Due to wind's intermittency additional thermal reserve capacity may be required, which reduces wind's ability to de-carbonise power systems (Denny and O'Malley, 2007). A number of previous studies have estimated the impact of increased wind on emissions from the electricity sector, though they do not specically examine the inuence of NAO (Clancy et al, 2015;Amor et al, 2014;Cullen, 2013;Wheatley, 2013;Kane et al, 2013;Traber and Kemfert, 2011;Denny and O'Malley, 2006). The consensus is that additional wind penetration reduces emissions and is most eective in reducing emissions in exible systems but also that the level of emissions reduction is generally greater when wind is displacing (baseload) coal generation plants.…”

In recent years there has been an increasing deployment of wind-powered generation technology, i.e. wind farms, on electricity networks across Europe. As this deployment increases it is important to understand how climate variability will affect both windpowered and non-renewable power generation. This study extends the literature by assessing the impact of NAO, via wind-power generation, on carbon dioxide emissions from the wider electricity system. A Monte Carlo approach is used to model NAO phases, generate hourly wind speed timeseries data, electricity demand and fuel input data. A unit commitment, least-cost economic dispatch model is used to simulate an entire electricity system, modelled on the all-island Irish electricity system. Our results confirm that the NAO has a significant impact on monthly mean wind speeds, wind power output, and carbon dioxide emissions from the entire electricity system. The impact of NAO on emissions obviously depends on the level of wind penetration within an electricity system but our results indicate that emissions intensity within the Irish electricity system could vary by as much as 10% depending on the NAO phase within the next few years. The emissions intensity of the electricity system will vary with the NAO phase. Terms of use: Documents in

“…Previous research has explored the emissions implications of renewable energy (1)(2)(3)(4)(5)(6)(7). The US Department of Energy estimates that achieving 20% wind penetration in the United States would reduce CO 2 emissions by 825 million metric tons by 2030 (1).…”

When wind or solar energy displace conventional generation, the reduction in emissions varies dramatically across the United States. Although the Southwest has the greatest solar resource, a solar panel in New Jersey displaces significantly more sulfur dioxide, nitrogen oxides, and particulate matter than a panel in Arizona, resulting in 15 times more health and environmental benefits. A wind turbine in West Virginia displaces twice as much carbon dioxide as the same turbine in California. Depending on location, we estimate that the combined health, environmental, and climate benefits from wind or solar range from $10/MWh to $100/MWh, and the sites with the highest energy output do not yield the greatest social benefits in many cases. We estimate that the social benefits from existing wind farms are roughly 60% higher than the cost of the Production Tax Credit, an important federal subsidy for wind energy. However, that same investment could achieve greater health, environmental, and climate benefits if it were differentiated by region.

“…Various aspects of our methods to estimate GHG and air pollution benefits build on or complement approaches used by U.S. regulatory agencies (GAO 2014; EPA 2015c) and academic researchers (NRC 2010;Arent et al 2014;Buonocore et al 2016a;Buonocore et al 2016b;Callaway et al 2015;Chiang et al 2016;Cullen 2013;Graff Zivin et al 2014;Driscoll et al 2015;Fann et al 2012;Johnson et al 2013;Kaffine et al 2013;McCubbin and Sovacool 2013;Novan 2014;Rouhani et al 2016;Siler-Evans et al 2013;Shindell 2015).

PREFACEThis is one report in a series that explores the costs, benefits, and other impacts of state renewable portfolio standards (RPS), both retrospectively and prospectively. The first report, A Survey of State-Level Cost and Benefit Estimates of Renewable Portfolio Standards, published in 2014, comprehensively summarized historical RPS compliance costs, drawing in part on estimates developed by utilities and state regulatory agencies. The study also reviewed analyses of the broader societal benefits and impacts of several states' RPS policies, typically conducted for or by the regulatory agencies or RPS administrators in those states. However, the small number of such studies, and their widely varying methods and scopes, ultimately limited the ability to compare benefits across states or to generalize beyond the specific studies performed. That limitation set the stage for future reports.The second report in the series, A Retrospective Analysis of the Benefits and Impacts of U.S. Renewable Portfolio Standards, published in January 2016, analyzed historical benefits and impacts of renewable energy (RE) used to meet all state RPS policies, in aggregate, employing a consistent and well-vetted set of methods and data sets. The analysis focuses on three specific benefits: air pollution, greenhouse gas emissions, and water use. It also analyzes three other impacts: gross job additions, wholesale electricity market price suppression, and natural gas price suppression. These are an important subset, but by no means a comprehensive set, of all possible effects associated with RPS policies. That report did not include a comparison of costs and benefits of renewables used to meet RPS policies, and nor did it assess the potential costs, benefits, and impacts prospectively based on future increases in RPS targets.The present report fills that gap by evaluating the future costs, benefits, and other impacts of renewable energy used to meet current state RPS polices. It also examines a future scenario where RPSs are expanded. The analysis examines changes in electric system costs and retail electricity prices, which include all fixed and operating costs, including capital costs for all renewable, non-renewable, and supporting (e.g., transmission and storage) electric sector infrastructure; fossil fuel, uranium, and biomass fuel costs; and plant operations and maintenance expenditures. The analysis uses the same framework as the second report to analyze three specific benefits: air pollution, greenhouse gas emissions, and water use. It also analyzes two other impacts, RE workforce and economic development, and natural gas price suppression.The terminology applied in this series does not align precisely with the traditional concepts of costs and benefits, but rather is a function of how RPS programs have often been evaluated in practice. This analysis series, particularly the present report, evaluates renewable energy used to meet RPS policies in terms of costs, benefits, and other impacts:• Cost metrics presented in this r...
