This article is part two of five in a series where we’ll be looking at the renewable energy that is produced by each state in the U.S. We take a look at the percentage of green energy that has been generated by each state and provide some interesting data about the renewable energy that is produced there.

View part one here

11. Hawaii

Total renewable energy produced (percent): 100

Hawaii runs on 100 percent renewable energy. This is largely down to the states biomass industry which equates to over 50 percent of its total renewable power production. Hawaii’s energy production totals 16,382 billion BTUs, which is 0.22 percent of the total United States renewable energy production.

Hawaii imported 90 percent of the energy it used (mostly in petroleum fuel) in 2014. Later in 2015, the state had the highest electricity prices in the nation.

In 2014 (because of its hot, tropical climate) Hawaii had the fourth-lowest energy use in the United States.

12. Idaho

100 percent of the energy that Idaho produces is renewable.

Idaho is rich in renewable energy resources. The renewable sources in the state provide 100 percent of energy production. This totals 139,888 billion BTUs. This is 1.86 percent of the total United States renewable energy production.

As well as having the 5th lowest average electricity prices in the U.S. in 2014, 82 percent of Idaho’s electricity generation came from renewable energy resources in that year.

13. Illinois

Total renewable energy produced (percent): 11.54

Renewable sources provide more than 11 percent of Illinois's total energy production. This totals 239,478 billion BTUs which is 3.18 percent of the total renewable energy production in the nation.

Illinois is a vital transportation centre for natural gas and crude oil that moves throughout North America.

In January 2015, Illinois was ranked fourth in the nation in regards to leading the Midwest in crude oil refining.

Illinois households use 129 million BTU of energy per household annually, this is 44 percent more than the average in the United States (according to EIA's Residential Energy Consumption Survey).

14. Indiana

Total renewable energy produced (percent): 15.79

Renewable sources provide 15.79 percent of the state’s energy production, this totals 152,917 billion BTUs which is 2.03 percent of total U.S. renewable energy production.

Indiana is a key manufacturer of ethanol. Indiana's ethanol plants (as of January 2016) were capable of manufacturing more than 1.2 billion gallons of ethanol per year.

15. Iowa

Total renewable energy produced (percent): 91.69

In Iowa, renewable sources provide 91.69 percent of the state’s energy production. This totals 539,707 billion BTUs. Which is 7.16 percent of the total United States renewable energy production.

Iowa is the main producer of ethanol in the U.S. The state had over 27 percent of the nation's fuel ethanol operating capacity in 2015.

The state has reduced its usage of coal in recent years. In 2015, 53 percent of Iowa's net electricity generation was fuelled by coal, which was reduced from 59 percent in 2014.

16. Kansas

Kansas produces 11.15 percent of its energy from renewable sources. This totals more than 91,144 billion BTUs which is 1.21 percent of total U.S. renewable energy production.

One of the top-producing natural gas fields in the U.S. is located in Kansas. The Hugoton Gas Area is located in southwestern Kansas.

21 percent of electric generation in Kansas came from renewable wind energy in 2014. This means that wind energy is the state’s second biggest power provider, after coal.

17. Kentucky

Total renewable energy produced (percent): 2.35

Renewable sources provide 2.35 percent of Kentucky's energy production. This totals 66,193 billion BTUs which is 0.88 percent of total U.S. renewable energy production.

Kentucky’s energy is mostly produced through their coal industry. Most of the state’s natural gas production comes from the Big Sandy field in the east of the state.

Kentucky is home to the United States first net-zero energy public school.

18. Louisiana

1.47 percent of the energy that Louisiana produces is renewable. This totals 107,406 billion BTUs.

Louisiana is home to the Louisiana Offshore Oil Port (LOOP) which is the only port in the U.S. that is capable of berthing Ultra Large Crude Carriers, the largest ocean-going crude oil tankers.

19. Maine

Maine produces 100 percent of its energy renewably. This is mostly down to the states creditable biomass industry which equates to over 60 percent of the state’s total energy production.

Maine’s energy production totals 139,654 billion BTUs. This is 1.85 percent of the total United States renewable energy production.

Almost 90 percent of Maine is thick forest. This means that wood products including biomass fuels are a vitally important part of the state’s rural economy.

20. Maryland

17.14 percent of the energy that Maryland produces is renewable. This totals 42,549 billion BTUs which is 0.56 percent of the total United States renewable energy production.

The Dominion Cove Point in Maryland is the only liquefied natural gas import terminal in the whole of the Mid-Atlantic. Export operations from this port are expected to begin in the late part of 2017.

Renewable energy resources accounted for 7.5 percent of Maryland’s total net electricity generation in 2015.

Trafigura and Yara International explore clean ammonia usage

Commodity trading company Trafigura and Yara International sign MoU to explore developing ammonia as a clean fuel in shipping

Independent commodity trading company Trafigura and Yara International have signed an MoU to explore developing ammonia as a clean fuel in shipping and ammonia fuel infrastructure.

Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050. 

How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.

Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:

  • The supply of clean ammonia by Yara to Trafigura Group companies
  • Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
  • Development of new clean ammonia assets including marine fuel infrastructure and market opportunities

Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.  

There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.

Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.

Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.

Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.

It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
