Power generation for the existing electrical grid is largely based on the combustion of fossil fuels. Global concerns have been raised regarding the environmental sustainability of the system due to life cycle impacts, including land losses from fuel extraction and impacts of combustion emissions. An approach to reduce carbon emissions of fossil fuel-based energy employs the conversion of wind energy to electrical energy. The work presented describes modern wind power plants and provides an environmental assessment of a representative wind park from a life cycle perspective. The empirical analysis uses commercially available data, as well as information from an existing wind power plant. The life cycle assessment (LCA) study for a modern wind farm in the northwestern U.S. found that environmental benefits of avoiding typical electricity production greatly outweigh the impacts due to wind turbine construction and maintenance. Effects of component reliability, varying capacity factors, and energy portfolio are explored.

The ever-increasing popularity of finding alternative forms of renewable energy has seen an increased interest and utilization of wind energy. The objective of this research therefore, is to evaluate the environmental impacts and energy performance of wind farms. This study was operationalized in Jordan using a life-cycle assessment (LCA) method. The environmental impact is evaluated through lifecycle emissions that include all emissions during various phases of the project. The energy performance is illustrated by the energy indicators. The latter is the energy payback ratio (EPR) and the energy payback time (EPT). This study was conducted on a 38 Vestas V112 3-MW wind turbine located in the southern region of Tafilah in Jordan that is host to the country’s first wind farm. SimaPro 7.1 software was used as the modeling platform. Data for this study were collated from various sources, including, manufacturers, the wind turbine farm, and local subcontractors. A software database was used for the modeling process, and the data obtained modeled in accordance with ISO 14040 standards. The findings of this study indicate that the impacts of the transportation and installation phases were moderate, with the largest negative environmental impact deriving from the manufacturing phase. To remedy some of the negative impacts in these phases, green cement was used for the turbine foundation to limit the environmental impacts to be had during the installation phase, while the transportation phase saw the utilization of locally-manufactured turbines. Furthermore, an evaluation of the study’s results revealed that the energy payback period of the wind farm is approximately 0.69 year (8 months), while the payback ratio is 29, and the annual CO2 saving estimated to be at 2.23 × 108 kg, 3.02 × 108 kg, 3.10 × 108 kg for an annual generated power of 371, 501, and 515 GWh/year.
