Energy generation from traditional sources is being replaced by alternative sources — solar, wind, hydro etc. Courtesy of advancements in technology, costs of energy production from renewable sources are lowering. Declining cost and emission-less production are the primary reasons for increasing popularity of renewable sources.Per a recent report by Energy Information Administration (“EIA”), production from wind energy will increase in the near future. EIA expects wind energy to provide 6.4% and 6.9% of total utility-scale electricity generation in the United States in 2018 and 2019, respectively, up from 6.3% in 2017. With increasing asset installation, EIA expects wind to surpass hydro as the major source of renewable electricity generation.Price PerformanceAlliant Energy’s shares have rallied 8.5% in the last 12 months compared with 2.2% rise of the industry it belongs to.
