The Iowa Environmental Council released Tuesday a report called “Iowa’s Road to 100% Renewable“. The report lays out the steps necessary for Iowa to transition to 100% renewable energy by 2050, a goal that many other states across the U.S. have already set for themselves in recent years.

The IEC concluded that, by 2050, Iowa will need to generate 30,000 to 61,000 MW of wind and 5,000 to 46,000 MW of solar energy to fully transition to renewable sources. The state currently generates 10,000 MW of wind and 110 MW of solar energy.

That sets a wide range, but the IEC analysis incorporated 12 studies on renewable energy growth with a variety of unknown variables. Electrification of fossil fuel sectors, like transportation, may increase exponentially by 2050, resulting in a higher demand for electricity. This, along with the current rate of general increase in electric demand, could alter the amount of renewable energy Iowa requires. The report also considers studies that incorporate the possible use of nuclear power and carbon capture and storage as additional renewable energy options.

Iowa is currently one of the country’s leading producers of wind energy. According to an article posted by T&DWorld, Iowa generated 41.9% of its electricity using wind in 2019. However, continued growth of wind energy necessary for the plan’s success will require increasing support from Iowa’s government and residents.

Some support has waned in recent years. Renewable energy tax credits have reached their capacity, according to The Iowa Utilities Board, and some Iowans have become wary of the number of wind turbines dotting the countryside across the state. Public concern over the land and resources required to expand wind energy production is a hurdle that must be faced before the goals outlined in “Iowa’s Road to 100% Renewable” can be reached.

Almost 250,000 Americans worked in solar jobs as of 2019, a 2.3% increase since 2018 as reported in the 10th annual National Solar Jobs Census.  The solar industry is seeing an increase in employment after decreasing numbers the past two years.  The results of the census are summarized in an interactive website which provides data for each state down to the county scale.

Iowa employed over 800 people with solar jobs in 2019, ranking 39th in the country.  While not a leader in solar energy, Iowa is the state with the second highest wind energy capacity, with wind energy representing more than a third of the state’s electricity production as of 2016.  Renewable energy represents almost two-fifths of Iowa’s electricity generation, and the proportion is only expected to continue to increase.

Employment in solar nationally has increased by over 167% within the past decade alongside a 70% drop in cost within the same time frame.  To ensure the future of solar energy, an MIT study suggests that government policies are required to incentivize it’s use and to continue the growth caused by the continuing drop in prices.

Iowa lawmakers, advocates reach compromise on controversial solar bill

Iowa legislators have reached a compromise on last year’s controversial “Sunshine Tax” bill. The Iowa Capital Dispatch reported Friday that both legislative chambers have unanimously approved bill versions of the“Solar Act,” which are awaiting Gov. Reynolds’ approval.

According to the dispatch, the act would allow owners of home, business or farm solar arrays to continue selling excess energy to utility companies at the retail rate. Last spring, a controversial bill proposed an extra $300 annual fee for solar customers who sell excess energy, meant to cover the cost of using the electric grid. Critics said the fee would make it much harder for private owners to pay off their investment into solar, essentially killing the largely private solar industry in Iowa.

The new version also orders an independent cost-benefit analysis of solar power in Iowa, meant to make sure all parties pay their fair share. Following the study, the Iowa Utilities Board would make a recommendation for reasonable billing methods. Existing solar owners would be immune to recomended changes in billing methods.

Iowa City and MidAmerican may team up on solar project

MidAmerican Energy has proposed its first-ever solar energy project: a public-private partnership with the City of Iowa City.

The city would lease nearly 19 unused acres at Waterworks Prairie Park to MidAmerican for 30 years, installing 10,000 solar panels, according to The Gazette. The energy generated would be able to power 580 average Iowa homes, a MidAmerican representative said in the article.

The Iowa City City Council will hold a hearing on the proposal later this month. If the city approves the plan, it will receive annual payment for the land.

The project would not impact the park’s walking trail. The Gazette reported that the land in question is currently planted with prairie, which would be replaced with “low-growth pollinators and perennials.”

 

 

 

Iowa Energy Districts bring local leadership to renewables

Though the state of Iowa as a whole has focused on shifting to renewable forms of energy–wind in particular–for years, some localities feel the transition has not been speedy enough. A handful of “Energy Districts” have formed in recent years with intent to push their communities forward in the renewable energy adoption.

These districts are independent and non-partisan entities led by a small staff and a local board of directors, according to the Winneshiek Energy District website. Winneshiek’s was the first such district to form (in 2010) and has since has encouraged and aided others. A recent Energy News Network article said Iowa now has eight districts active or in planning, including two in Iowa City and Des Moines.

The Energy Districts are modeled after Soil and Water Conservation Districts, local authorities formed after the 1930s Dust Bowl to encourage local solutions to resource conservation. With the goal of empowering locals to transition to renewables on their own terms, Energy Districts provide services such as:

  • Energy auditing and planning assistance to homes, farms, businesses and institutions (often in partnership with Green Iowa AmeriCorps).
  • Educational opportunities
  • Advocacy for improved renewable energy policy
  • Guidance to other localities hoping to establish Energy Districts

A fact sheet provided by the Winneshiek County Energy District says the entity has helped create a $14 million investment in renewable energy, over 100 energy jobs and a 100,000 ton reduction in greenhouse gas emissions in Winneshiek County alone.

UI professor and researcher calls on economic reform to address the changing climate


By Julia Shanahan | September 20th, 2019

Jerry Schnoor, University of Iowa civil and environmental engineering professor and co-director of the Center for Global and Environmental research, wrote an op-ed in the Des Moines Register, calling for economic reform to reduce global carbon emissions.

Schnoor listed several economic changes that would help to reduce carbon emissions by 45 percent in the next ten years:

  • Install solar panels and build large solar power plants
  • Improve battery storage
  • Massive reforestation
  • Implement regenerative agriculture to keep carbon in the ground
  • Expand electrical vehicle usability

Schnoor pointed to extreme weather events like the spring flooding from the Missouri river, category five hurricanes, wildfires, drought, and failed crops. This op-ed comes ahead of the Sept. 20 global climate strikes, where people of all ages from all over the world are rallying for environmental reform. 

Schnoor says in the piece that “time is running out” to address the changing climate, writing,  “Without a drastic reduction in burning of fossil fuels now — a reduction of 45% in the next 10 years — we commit ourselves to increasing climate catastrophes at great economic cost.”


In Iowa, where agriculture is a leading industry, many have called on farmers across the midwest to begin more sustainable farming methods, like planting cover crops, leaving organic materials in the fields after harvest, and adding additional crops to a soybean-corn rotation.

South Sioux City to become “demonstration site” for stored electrical power


Julia Shanahan | June 7th, 2019

South Sioux City, located in northeast Nebraska, will become a “demonstration site” this winter for the storage of electric power generated by the city’s 1,200 solar panels.

A large battery, described as a “semi trailer without wheels”, will be able to store 1.5 megawatts of power and cost about $1.8 million, according to a report from the Iowa-based Sioux City Journal. This project is a big step in the field of renewable energy because power would be able to be stored for days with less wind or sunlight.

The report also said that solar energy makes up roughly 5 percent of the city’s electricity usage, and that South Sioux City now gets about half of its electricity from renewable sources, like solar, wind, and hydroelectric power. In Iowa, about 2 percent of renewable energy comes from a source other than wind.

The city hopes to continue taking steps to lessen its dependence on the Nebraska Public Power District, and eventually fully phase out of their contract.

As South Sioux City takes steps toward utilizing sustainable energy, Iowa remains a leading state in the field of renewable energy.

In 2018, Iowa’s 3,400 wind turbines produced 34 percent of the state’s electricity – the second highest share for any state, according to the U.S. Energy Information System. Additionally, among the top five energy-consuming states, Iowa was the only non-crude oil-producing state on a per-capita basis in 2018.

Iowa also remains the largest producer of ethanol in the U.S., producing one-fourthof the country’s ethanol production capacity.
