Wind power in Indiana was limited to a few small water-pumping windmills on farms until 2008 with construction of Indiana's first utility-scale wind power facility, Goodland (phase I) with a nameplate capacity of 130 MW. As of March 2024, Indiana had a total of 2,743 MW of wind power capacity installed, ranking it 12th among U.S. states. Wind power was responsible for 4.8% of in-state electricity production in 2016.

Solar power in Indiana has been growing in recent years due to new technological improvements and a variety of regulatory actions and financial incentives, particularly a 30% federal tax credit for any size project.

As of 2026, Indiana ranked 11th among U.S. states for installed solar power with 6.5 GW of photovoltaic panels, up from 18th place with 136 MW in 2015. The state nearly doubled its installed capacity in 2025, installing the third most capacity that year.

Earth Charter Indiana has worked to develop leadership in sustainability and climate action for almost 20 years. Its Youth Power Indiana initiative works with students in elementary through high school, and with mayors and municipal officials to develop sustainability and resiliency programs. Young people have advocated climate policy which has been adopted in seven cities: Carmel, Indianapolis, Lawrence, South Bend, Goshen, Bloomington and West Lafayette.

Publicly available data is available to communities and government via the Hoosier Resilience Index, an online database listing information such as "precipitation, flood plain and land use maps – for every community in the state of Indiana."

Carbon Neutral Indiana (CNI) is a non-profit organization that works with households, businesses, and academic institutions to measure, offset, and reduce their carbon footprint. Their goal is to spark a movement amongst Hoosiers to ensure Indiana becomes carbon neutral as soon as possible.

Indiana nonprofits remain uncertain if — or how — some climate grants will progress, under President Donald Trump's January 20, 2025, executive order freezing money from the 2022 Inflation Reduction Act, complicated by related lawsuits filed with various federal courts. Kaylee Dann, executive director of Greater Indiana Clean Cities—which helps administer grants to install electric vehicle chargers across the state—said, "A lot of these locations that are in the inner cities have a lot of traffic. So by putting in charging stations, you're encouraging more zero emission vehicles in those areas, which would lower the impact and that health burden on those communities." The U.S. Department of Transportation (DOT) will issue guidelines in spring 2025 regarding the program to install chargers on interstate highways. But Dann said US DOT already canceled a chargers-focused meeting in Indiana cities and towns — making it unlikely those projects will move forward. Those EV charger stations were to be installed in poorer areas of central and northern Indiana.

Climate change in Indiana encompasses the effects of climate change, attributed to man-made increases in atmospheric carbon dioxide, in the U.S. state of Indiana. The annual mean temperature in Indiana has increased 1.2 °F (0.67 °C) since 1895. According to the United States Environmental Protection Agency (EPA) "Northern Indiana has warmed more than Southern Indiana".

Merry Lea Environmental Learning Center of Goshen College is located just south of Wolf Lake at Bear Lake in Noble County, Indiana, United States. Merry Lea is the largest privately held land reserve in the state of Indiana. The center serves as a field laboratory for students at Goshen College who are studying ecology, environmental education and agroecology. In addition, Merry Lea provides environmental educational experiences for elementary students in the center's service area which includes the Fort Wayne metropolitan area as well as Warsaw, Huntington, Kendallville, Goshen and Elkhart.

The facility's 1,150 acres (4.6 km²) include most of northern Indiana's ecosystems including peat bogs, swamp maple forest, upland mesic forest, old field, prairie, and lakeshore. An esker deposit with 50 ft (15 m) relief that extends for nearly half a mile (1 km) is the most striking geological feature. The center also features Rieth Village, a complex of energy efficient buildings completed in 2006 that provide housing and classrooms for college students. Rieth Village features a 10 kW wind generator mounted on a 100 ft (30 m) tower and 4.8 kW photovoltaic array.

The Lilly ARBOR Project is a part of an experimental riparian floodplain reforestation and ecological restoration program, located along the White River in Indianapolis, Indiana, United States. ARBOR is an acronym for "Answers for Restoring the Bank Of the River".

Sycamore Land Trust is a 501(c)(3) non-profit member-supported land trust headquartered in Bloomington, Indiana, United States.

It works to preserve the disappearing natural and agricultural landscape of southern Indiana. Sycamore's service area includes 26 southern Indiana counties: Bartholomew, Brown, Clark, Crawford, Dubois, Daviess, Floyd, Gibson, Greene, Harrison, Jackson, Knox, Lawrence, Martin, Monroe, Morgan, Orange, Owen, Perry, Pike, Posey, Scott, Spencer, Vanderburgh, Warrick, and Washington.

The trust is an affiliate of the American Land Trust Alliance. In 2023, the trust has 7 full-time staff and over 100 volunteers.

Sycamore has an active and award-winning Environmental Education Program that helps people in southern Indiana build an understanding of Indiana's natural heritage and the Earth's delicately balanced living systems. Sycamore believes that nature is the ultimate educator and offers lessons that reinforce school curriculum as well as program for families and the community.

The Environmental Education program focuses on three approaches: individual teachers and classes; larger scale projects; and cooperative projects. Through classroom work, Sycamore leads outdoor discovery activities, hiking, exploring, math or science lessons, and reflective writing. Larger projects include a watershed study project on Beanblossom Creek and cooperative field days that create a dynamic learning environment. In 2023, the Environmental Education plans to work with 6,000 people.

Indiana ( IN-dee-AN-ə) is a state in the Midwestern region of the United States. It borders Lake Michigan to the northwest, Michigan to the north and northeast, Ohio to the east, the Ohio River and Kentucky to the south and southeast, and the Wabash River and Illinois to the west. Nicknamed "the Hoosier State", Indiana is the 38th-largest by area and the 17th-most populous of the 50 states. The state's capital and largest city is Indianapolis. Indiana was admitted to the Union as the 19th state on December 11, 1816.
