Iowa Wind Energy Fact Sheet
The five states with the most wind capacity installed at the start of 2017 were:
Texas (20,321 MW)
Iowa (6,917 MW)
Oklahoma (6,645 MW)
California (5,662 MW)
Kansas (4,451 MW)
Here's a company that is working toward 100% wind-generated power for its customers:
Iowa is a national leader in wind energy, producing the highest percentage of electricity by wind of any state–over 36%. Iowa was the first state to generate more than 30 percent of electricity from wind.
Iowa’s total wind capacity by the end of 2016 was 6,917MW. This ranks second nationally in installed capacity.
Wind energy in Iowa grew from about 800 MW in 2005 to over 6,900MW today. Iowa’s electric rates have remained below the national average during this time. New wind energy in Iowa is a low cost option and less expensive than new coal, natural gas, or nuclear.
This is a little outdated, but has a ton of data:
MidAmerican Energy said Wednesday it plans to invest $922 million in added wind-power capacity, equaling as much renewable energy as its customers use.
"If the project is approved, it will allow our customers to get 100 percent of their annual energy use from a clean, renewable and cost-effective source," said Adam Wright, MidAmerican's CEO. "This is, no doubt, historic."
MidAmerican said it will be the first investor-owned electric utility nationally to meet the goal, which the Des Moines utility announced in 2016.
The latest wind investment, expected to be completed in late 2020, would enable the company to freeze consumer rates, possibly up to 15 years, MidAmerican said.
By 2021, MidAmerican Energy's wind-energy capacity will equal customers' energy needs.
EIA: Cost and Performance Characteristics of New Generating Technologies, Annual Energy Outlook 2019
Presented below are graphs and tables of the cost data for generators installed in 2016 based on data collected by the 2016 Annual Electric Generator Report, Form EIA-860. The cost data for certain generation technologies were omitted to avoid disclosure of individual company data.
EIA expects to publish construction cost data for generators installed in 2017 in July 2019.
What isn't factored into coal costs is the cost to our economy that rising greenhouse gases are costing in disaster mitigation from extreme weather, drought, mega-fires, and stronger hurricanes, plus the incalculable harm of species extinctions due to habitat changes (e.g. coral reefs, American Pika). Not that solar, wind, and hydroelectric don't also cause environmental harm, because they do, just not as egregiously as carbon-based energy.
The tables presented below will be incorporated into the Electricity Market Module chapter of the U.S. Energy Information Administration’s (EIA)Annual Energy Outlook 2019 (AEO2019) Assumptions document. Table 2 represents EIA’s assessment of the cost to develop and install various generating technologies used in the electric power sector.
