Indiana is positioning itself as a national leader in clean energy, driving economic growth through innovative projects and significant investments.

Economic development officials said Indiana's heavy industry and manufacturing capabilities make it a natural partner for emerging technologies like carbon capture, hydrogen and solar power.

Andrea Richter-Garry, senior vice president of global strategy for the Indiana Economic Development Corporation, said clean energy is transforming the state's economy and creating new opportunities.

"A great example of that would be Heidelberg Materials down in Mitchell, Indiana, receiving a huge Department of Energy grant to be able to push forward a carbon capture project that will lead to low carbon cement," Richter-Garry outlined. "Wabash Valley just announced a huge project in Terre Haute."

Some opponents have said the best approach is to hold back on renewables, arguing technology will get better and be less disruptive to landscapes. Richter-Garry countered Indiana's manufacturing strength is a critical component of the transition. The clean energy industry has brought in $12 billion in capital investments, more than $40 million annually in taxes, and about $35 million a year in lease payments to Indiana landowners.

Richter-Garry noted Indiana's workforce and existing infrastructure are well-suited to produce essential clean energy components, including wind turbines and solar panels, helping meet national and global energy goals.

"The Mammoth Solar project, that 13,000-acre solar farm is going to generate 1.3 gigawatts of power," Richter-Garry pointed out. "That's 75,000 homes. Indiana again has the correct kind of landscape as well as some of the local partnerships to be able to continue that trend."

Indiana's clean energy initiatives are not just about sustainability, they are about securing the state's economic future. By leveraging its strengths in manufacturing and innovation, Indiana is paving the way for a prosperous green economy to benefit communities across the state.

We talk a lot about carbon emissions in the context of climate change, but some of the most dangerous emissions aren't carbon at all. They're methane - a colorless, odorless glass that's primarily produced biologically and warms the planet much faster than carbon dioxide. The Biden administration took some good first steps to reduce America's methane emissions - but will President-elect Donald Trump build upon these steps when he assumes office, or claw back the progress that's been made?

Understanding Methane Emissions

Methane is one of the three main greenhouse gasses, along with carbon dioxide and nitrous oxide. The Earth and its various ecosystems produce methane naturally; freshwater lakes, wetlands and permafrost are the primary natural sources of methane. It's also the main component of natural gas.

However, a 2021 United Nations report found that currently, roughly 60 percent of methane emissions are anthropogenic, or the result of human activity. Agriculture produces more methane than any other sector around the world, and around 90 percent of anthropogenic methane emissions come from one of three sources: agriculture, fossil fuels and waste.

The line between anthropogenic and naturogenic (naturally-occurring) methane emissions can be blurry. For instance, a major source of methane is cow burps (and, to a lesser extent, farts). While cows are obviously "naturally-occurring," animal agriculture is not, and neither is the amount of cows we've brought into existence. The sheer amount of methane produced by cows is the result of our domestication of them, not any sort of natural process.

Similarly, methane is the main ingredient in natural gas, and natural gas existed long before humans came around. But it's the extraction of natural gas that actually causes this methane to enter the atmosphere, and natural gas extraction is a human activity.

Semantics aside, one thing is certain: There's a lot more methane in the atmosphere than there would have been had humans never existed. And that's not good.

Why Is Methane a Problem?

Like other greenhouse gasses, methane contributes to climate change by warming the atmosphere and the planet. But it works a bit differently than carbon dioxide, the most common greenhouse gas.

Carbon dioxide makes up almost 80 percent of all greenhouse emissions, whereas methane constitutes just over 11 percent. In addition, methane dissipates rather quickly; it only sticks around in the atmosphere for around a decade, whereas carbon dioxide can linger for up to 1,000 years.

This might have you thinking that methane isn't that big of a deal, at least insofar as greenhouse gasses go. The problem is that methane traps much, much more heat than carbon dioxide - so much so that, over a 100 year period, methane has 27-30 times the global warming potential of carbon dioxide. Over the course of 20 years, it has 80 times the warming potential.

In addition to warming the environment, methane also makes the air dangerous to breathe, because when sunlight interacts with methane, it forms a pollutant called tropospheric ozone. Although tropospheric ozone only stays in the air for a few weeks at most, it can be fatal; it's estimated that up to a million people die every year from respiratory diseases caused by ozone pollution, and methane is a major contributor to this.

How Do Farms Contribute to Methane Emissions?

Around one-third of all anthropogenic methane emissions come from livestock. There are two main reasons for this.

First, there are the burps. A number of animals produce methane as a natural byproduct of their digestive systems; these animals are known as ruminants, and they include not only cows but also sheep, goats, yaks and more. When ruminants burp, they release methane into the air. These are called enteric methane emissions.

The other main source of livestock-related methane emissions is the animals' manure - or, to be more precise, the manner in which farmers store the animals' manure.

Manure management is a significant component of livestock farming. One of the more common ways of storing manure is to put it in large lagoons or pits; this prevents it from leaking into nearby soil and waterways, and also allows farms to more accurately monitor and track their farms' manure output.

Over time, however, the top layer of manure in the lagoon hardens, which prevents oxygen from reaching the manure below. And this is a problem, because when manure is placed in an oxygen-free environment, the microorganisms that produce methane thrive and proliferate, thus increasing its methane emissions. That's exactly what happens in manure pits.

These two factors - enteric emissions and manure (mis)management - account for 80 percent of agriculture-related methane emissions. The other 20 percent comes from rice farming. Rice is a semi-aquatic plant that requires a layer of standing water to grow; this water prevents oxygen from reaching the microbes in the soil, allowing them to reproduce and create methane in a manner similar to manure in a lagoon.

The problem of livestock-related methane emissions is exacerbated by the fact that global meat production has been on the rise for the last 60 years, on both an absolute and per-capita level. This makes reducing these missions all the more important - but how?

How Can Farmers Reduce Their Methane Emissions?

A number of solutions have been proposed, and in some cases implemented, for reducing methane emissions.

Many of these involve new or emerging technologies. There are feed additives that reduce the amount of enteric methane production in ruminants' stomachs, for instance, and manure aeration systems that allow oxygen to flow into stored manure on farms. One company is even developing a methane-trapping mask for cattle to wear while grazing.

Other methane reduction strategies are decidedly more low-tech, such as selectively breeding animals to produce less methane. Simply making livestock farms more efficient on the whole can also have an impact, as this results in increased output with no corresponding increase in methane emissions.

All of these solutions, however, face obstacles. Fernanda Ferreira, Director for Agriculture Methane at Clean Air Task Force, tells Sentient that one of the biggest challenges in methane mitigation is the simple fact that production facilities and logistical operations vary wildly from farm to farm.

"Let's look at the U.S.," Ferreira says. "When you think about goats, sheep, beef and dairy farmers, you have a little over a million farmers. So we're talking about one million different ways of managing these animals. Even if you zoom in into one specific region - let's say the West, or a state like California - there will be variation."

This variation, Ferreira says, complicates efforts to implement methane mitigation technologies on a wide scale, because every farm is a unique operation with slightly different needs, capabilities and restrictions.

"When you zoom in, you have a lot of variation of how farmers handle these animals," Ferreira says. "And this is directly linked to the challenge of adopting [methane reduction] technologies."

Another major challenge is cost. Many of these solutions are expensive, and the cost of implementing them falls on the farmers themselves. But while methane reduction benefits all of humanity in the long run, it doesn't offer farmers any benefit in the short run. As such, farmers largely aren't incentivized to adopt these technologies.

Lastly, there's the simple fact that a lot of this technology is still in the research and development phase. As of this writing, only one synthetic methane-reducing feed additive has been approved by the FDA, and that approval only came six months ago. Other proposed additives are prohibitively expensive, not very effective or come with other drawbacks. The methane-trapping cow mask also has several logistical issues, and has been criticized as a potential form of greenwashing.

What Has President Biden Done About Methane?

In 2021, the Biden administration unveiled the U.S. Methane Emissions Action Plan, a 20-page document with various initiatives and proposals for reducing U.S. methane emissions. They include incentives for farmers to reduce their methane emissions, new regulations aimed at doing the same, and the formation of an interagency task force to collect methane and use it for "on-farm renewable activities."

"The U.S. Methane Emissions Reduction Action Plan provides the framework for the work on agriculture methane emissions," Ferreira says. "The most important outcome that it supports is the deployment of climate smart-initiatives, such as the use of methane-reducing feed additives and the implementation, more broadly, of manure management practices."

In 2023, the Biden administration announced The National Strategy to Advance an Integrated U.S. Greenhouse Gas Measurement, Monitoring, and Information System (yes, that's the official name). This set of policies is geared at improving the tracking, monitoring and reporting of greenhouse emissions, both inside and outside of the government.

These two action plans, Ferreira says, are important first steps in tackling the methane problem-head on. In addition to all of this, the Inflation Reduction Act, passed in 2022, contained funding for a selection of "climate-smart" agricultural practices, including some aimed at reducing methane emissions from farms.

The Inflation Reduction Act also expanded the EPA's authority to regulate methane emissions, and created the Methane Emissions Reduction Program for the purpose of doing so. The Biden administration allocated $1 billion to this program in 2023, and in December, introduced new limits on methane emissions via the EPA.

However, these initiatives only apply to the oil and gas industries, so they won't have any effect on agricultural methane emissions.

What Will Trump Do About Methane?

Methane emissions weren't a central focus of the 2024 campaign, or even a tertiary one, and President-elect Trump made no policy pledges regarding methane. However, actions that he took as president during his first term strongly suggest that he'll seek to undo the Biden administration's progress on methane reduction.

During his time in office, Trump withdrew or weakened a number of federal regulations aimed at tracking and reducing methane emissions, including Obama-era rules that required oil and gas companies to monitor and fix methane leaks at their facilities and take steps to reduce methane emissions on public and tribal lands.

After Trump's 2024 victory, the Biden administration finalized a rule that fines oil and gas companies for their methane emissions, and there's been widespread speculation that Trump will scrap this rule once he assumes office.

Trump, who once said that climate change was a hoax perpetrated by China to make U.S. manufacturing less competitive, withdrew or weakened over 100 environmental regulations during his first term. Nothing he's said or done indicates that he's changed his tune on climate matters since then, so it seems likely that he'll continue rolling back environmental protections, including those aimed at reducing methane emissions.

While this would be unfortunate, Trump is just one person, and America is just one country. There are plenty of other leaders around the world, both in the private and public sectors, making efforts to curb methane emissions.

Canada, Mexico, Japan and several other countries have made significant investments in methane reduction as part of the Global Methane Pledge, for instance. In addition, almost 100 mayors around the world have pledged to reduce their cities' emissions in accordance with the Paris Agreement, which Trump withdrew the U.S. from. Meanwhile, Bill Gates has invested millions in a feed additive company aimed at reducing enteric methane production in livestock.

There are, in other words, plenty of opportunities for global action on methane that don't involve the U.S. president.

The Bottom Line

Reducing methane emissions is no easy task; there are technological, financial, logistical and even dietary hurdles. But given methane's rapid-fire warming potential, overcoming these obstacles isn't optional, but necessary.

Our planet won't remain liveable for future generations without a sharp reduction in methane emission. The Biden administration took some good first steps in bringing about such a reduction, and hopefully, more steps from other world leaders will follow, even if the Trump administration rolls back progress on the issue.

Connecticut is the subject of an offshore wind study which aims to identify supply chain opportunities for the state and the Northeast region.

Connecticut is committed to creating 100% zero-carbon electricity by 2040. So far, it has procurements for 1.5 gigawatts of offshore wind. The state's first offshore wind farm will be operational next year.

Kristin Urbach, executive director of the Connecticut Wind Collaborative, said the study can explore many offshore wind priorities.

"To pinpoint areas where supply chains currently fall short to propose actionable items to strengthen it," Urbach explained. "Also to boost our local economic growth with the support of local manufacturers for its infrastructure development while promoting job creation and sustainable growth in Connecticut."

Urbach pointed out the state can fill supply chain gaps by utilizing the 12,000-person shipbuilding and repair industry. Some experts believe tapping into this workforce can build up offshore wind development.

Connecticut's offshore wind future is strained. Gov. Ned Lamont paused a multistate deal, delaying Connecticut's ability to reach its 2030 goals. The study's findings will be released next spring.

Similar studies are underway in Louisiana, Maine, and South Carolina. Like them, Connecticut can generate sizable amounts of offshore wind power.

Courtney Durham Shane, senior climate mitigation officer for the Pew Charitable Trusts, said offshore wind has quickly become a lucrative business nationwide.

"The United States has already seen $25 billion in offshore wind supply chain investment to date," Durham Shane noted. "Projections are showing that there could be upwards of $100 billion in private investment and nearly 50,000 jobs that are up for grabs domestically."

The New London State Pier terminal became the first East Coast offshore wind marshaling terminal with unobstructed ocean access. It can speed along the staging and assembly of several states' offshore wind projects. New York State's first offshore wind farm created 75 jobs at the facility, a number which is slated to double.

Major electric grid operator PJM Interconnection estimates it'll cost more than $14 billion to provide electricity for 2025-2026, up from $2.2 billion last year.

That price tag has advocates worried about rising utility bills and public health impacts, partly because of PJM's continued use of gas and coal.

Marcia Dinkins is the founder and executive director of the Black Appalachian Coalition and a member of Black Women for Change.

She said people in the company's 13-state region - including West Virginia and the Ohio Valley - have higher rates of cancer, developmental delays, premature birth, and death from the continued reliance on coal.

"We're seeing high rates of asthma and chronic illness," said Dinkins. "Families are already struggling with access to affordable health care."

PJM says increased usage, power plant shutdowns, and increased operation costs are all driving up the cost of electricity.

Mountain state ratepayers saw a 90% increase in average residential electricity bills between 2005 and 2020 - higher than all states except one, according to Conservation West Virginia.

Dinkins explained that grid operators use the capacity auction process to make sure there's enough power available to meet future demand.

"And so at the risk of the everyday citizen," said Dinkins, "this increase through their process becomes a burden to the people living in West Virginia or along the Ohio Valley."

A Pew Research Center survey from last year found 67% of Americans say the U.S. should prioritize developing alternative energy sources, such as solar and wind.

But just 31% say they are ready to phase out the use of oil, coal and natural gas completely.
