Residents can share their input at several points in the planning process. Counties and towns usually hold public meetings and hearings before adopting or updating a solar or wind ordinance, where community members can speak, ask questions, and submit written comments. Many local governments also create advisory committees or working groups that include residents, landowners, and other stakeholders. In addition, draft ordinances are often posted online or in government offices, giving people a chance to review and provide feedback before a final vote.
FAQ
Frequently Asked Questions
Here you’ll find answers to common questions about renewable energy development, siting, and permitting in North and South Carolina.
A measure of electricity defined as a unit of work or energy, measured as 1 kilowatt (1,000 watts) of power expended for 1 hour. For example, a 1,000 kW (1 MW) solar installation that operates at full capacity for 1 hour produces 1 MWh of energy. An average home in the Carolinas might use about 1 MWh of electricity every month.

Yes. The Center for Energy Education (C4EE) in Roanoke Rapids, North Carolina, regularly hosts workshops, field trips, and community events that give students, educators, nonprofits, and local groups the chance to learn about solar energy up close. Participants can tour solar arrays, participate in STEM-based activities, and explore how solar technology works in real-world settings. C4EE also partners with schools and community organizations to provide tailored programs that support classroom learning, workforce training, and clean energy awareness.

Solar projects are designed to minimize visual impacts in compliance with local regulations and zoning ordinances. These regulations often include setbacks, vegetative buffers, and other visual requirements. In North and South Carolina, setbacks specify the distance between a project and roads, residences, or property lines, increasing separation from surrounding areas. Vegetative buffers provide screening to help ensure the project is hidden from public view.
According to the North Carolina Sustainable Energy Association (NCSEA), counties in North Carolina saw an average increase of about $225,574 in real and personal property tax revenue following the installation of utility-scale solar projects. Similar studies have not yet been conducted in South Carolina.
Yes, solar PV modules can be recycled. For example, Solar Panel Recycling (SPR) in Salisbury, North Carolina, is able to recover about 95% of a photovoltaic (PV) module by cleanly separating materials such as aluminum, glass, silicon, copper, silver, and plastics, which are then reintegrated into the supply chain.

Solar PV modules produce relatively little waste compared with many other energy sources. Most waste comes at the end of a solar PV module’s life (usually after 25–30 years). Much of this waste, like glass, aluminum, and silicon, can be recycled.
The National Renewable Energy Laboratory (NREL) estimates that global solar PV module waste could reach 78 million tons by 2050, but this is much less than the waste produced by fossil fuels, such as coal. Recycling these materials can reduce the need for new raw materials and help make solar energy more sustainable.

Solar projects can minimize wildlife impacts by incorporating habitat-friendly design and vegetation practices. Fencing can be configured to allow small and medium-sized animals to move through the site—such as by raising the fence bottom or using woven or net wire with wider mesh openings—helping maintain natural movement and grazing patterns. Developers can also enhance habitat value by planting pollinator-friendly vegetation, using native seed mixes, and implementing thoughtful vegetation management. These practices support local ecosystems, create safe habitats, and provide broader environmental benefits throughout the life of the project.
The materials in solar PV modules are sealed within the module and protected from contact with air or water. Most solar PV modules are made with crystalline silicon, but about 40% of new modules installed in the United States use cadmium telluride. Cadmium telluride is non-volatile, does not dissolve in water, and has only about one-hundredth the toxicity of cadmium.

The development process for a solar energy project generally follows these steps:
– Securing Land – Developers obtain site access by purchasing, leasing, or entering into agreements with landowners.
– Assessing Solar Potential – The site is evaluated for solar resource availability, projected energy output, and overall cost-effectiveness.
– Obtaining Permits – Projects must receive local government approval to ensure zoning compliance. State or federal permits may also be required, particularly for projects on federal land. In those cases, the National Environmental Policy Act (NEPA) applies. NEPA requires federal agencies to assess the environmental effects of their proposed actions through reviews such as Environmental Assessments (EAs) or more detailed Environmental Impact Statements (EIS), which evaluate potential impacts on land, water, wildlife, and communities.
– Interconnecting to the Grid – Developers apply for an interconnection agreement, approved by the state public utilities commission. Developers are typically responsible for funding any necessary grid upgrades to maintain system reliability.
– Selling the Power – To sell electricity, developers usually enter into a Power Purchase Agreement (PPA) with a utility or third-party buyer. Rules for selling power to third-party buyers vary by state.
– Environmental Reviews – Projects are evaluated for potential impacts on wildlife, natural resources, and cultural or historic sites. Larger projects or those on federal land often undergo a more extensive federal review process under NEPA.
– Designing and Building – Once approvals are in place, the project is engineered, equipment is procured, and construction begins. Developers may oversee this themselves or contract with engineering, procurement, and construction (EPC) firms.
Effective November 1, 2025, the North Carolina Department of Environmental Quality (DEQ) is required to implement new decommissioning requirements for utility-scale solar projects. Any project with a capacity of 2 MW-AC or greater must register with DEQ and pay a fee, follow state decommissioning and site restoration standards, and submit a financial assurance mechanism (proof of funds to cover decommissioning costs).
Effective May 24, 2024, the South Carolina Department of Environmental Services (DES; formerly the Department of Health and Environmental Control) implemented decommissioning requirements for large solar energy systems. Five years before a project’s expected end of life, the owner must submit a decommissioning plan to DES for review and approval. Projects must also comply with state decommissioning and site restoration standards and provide a financial assurance mechanism (proof of funds to cover decommissioning costs).
When sunlight hits a solar PV module, the cells inside turn that light into electricity. The solar PV module first makes direct current (DC) electricity, and an inverter changes it into alternating current (AC), which is the kind of power homes and businesses use.
A solar PV cell is the basic unit that converts sunlight into electricity. Multiple cells are connected together and sealed to form a module, which is the standard unit sold by manufacturers. In everyday language, people often call a module a solar panel. Several panels can be connected together to form a larger system, sometimes called an array.

A solar PV module consists of a:
Frame: Provides structural support for the module (anodized aluminum)
Glass Layer: Protects the cells from the environment (tempered glass)
Encapsulant: Protects the solar cells from water and provides insulation (EVA: ethylene-vinyl acetate or similar polymers)
Photovoltaic (PV) Cells: Convert sunlight into electricity (silicon – monocrystalline or polycrystalline)
Backsheet: Insulates and protects the back of the module (durable polymer or composite layers)
Wiring: Conducts electricity between solar cells (silver or copper coated materials)
Junction Box: Houses electrical cables that connect one module to another (plastic box with waterproof seal)

Currently, there are no operational land-based wind projects in South Carolina. In neighboring North Carolina, you can see projects such as the Amazon Wind Farm near Elizabeth City (Perquimans and Pasquotank counties) and the Timbermill Wind Project near Edenton (Chowan County), where turbines are visible across the surrounding rural landscape.

Researchers at the University of Rhode Island analyzed Airbnb rental data before and after construction of the Block Island Wind Farm—the nation’s first commercial offshore wind facility. Their analysis showed that the turbines are associated with increased tourism on the island. During the peak months of July and August, Airbnb rentals on Block Island saw an average 19% rise in occupancy and a monthly revenue increase of roughly $3,490 compared with rentals in Narragansett and Westerly, Rhode Island, and Nantucket, Massachusetts. There was no significant effect observed in other months, and the authors noted that offshore wind farms may serve as an attraction rather than a deterrent.

Farmers benefit from wind energy facilities by earning additional income from leasing their land for projects while still growing crops and supporting grazing livestock. Lease payments provide financial support, enabling farmers to invest about twice as much in their farms compared to those without wind facilities. Wind farms are designed to allow continued agricultural use, with an estimated 98% of the area remaining available for farming activities.

The Amazon Wind Farm US East in Pasquotank & Perquimans Counties created more than 500 jobs during construction, employed more than 30 North Carolina-based companies, spent $18 million locally on construction, and has 17 full-time operations & maintenance workers. The average annual salary for Amazon Wind US East O&M workers is $80,000.
The Timbermill Wind Farm in Chowan County created over 200 construction jobs and relied heavily on local contractors, with over $25 million spent with North Carolina businesses during construction. This included local concrete providers, road and civil contractors, and transportation of the wind turbines themselves, which contain multiple U.S.-manufactured components, including steel tower sections and nacelles. Components were transported by both rail and sea through the Port of Morehead City and Chowan County’s Riverbulk Terminal. The project is estimated to generate up to $33 million in tax revenue over its lifetime and is expected to be the county’s largest taxpayer during its first year of operations.

A recent study by the North Carolina Sustainable Energy Association (NCSEA) found that a 54-turbine wind facility in Perquimans and Pasquotank counties resulted in a 193% increase in property tax revenue for Perquimans County. Comparable studies have not been conducted in South Carolina, as the state does not currently have any utility-scale wind projects.
A 2022 study published in the Energy Policy Journal found that wind projects led to meaningful increases in both median household income and home value. Researchers noted that the significant tax benefits from wind projects contributed to increased county investment in schools, highways, and hospitals, making the counties more attractive places to live.
In 2023, Lawrence Berkeley National Laboratory released a study that examined approximately 500,000 home transactions across 34 states and 428 different wind projects between 2005 and 2020, including data from both the preconstruction and operations phases. This new, large-scale study found no impacts from wind farms on home values in rural counties (with a population under 250,000), which host 94% of all installed wind capacity.

Offshore wind activity presents a low risk to marine mammals, including whales. Best management practices to reduce ship strikes, noise pollution, and species-specific impacts during construction, operation and maintenance, and decommissioning of wind energy areas are part of a dynamic research and monitoring process that developers must follow.

The US Coast Guard has publicly stated that they have no intention of limiting navigational and fishing access to the foundations of turbines in State or Federal waters.
The Bureau of Ocean Energy Management (BOEM) provides several public comment periods for the public to provide input during the regulatory process. So far, offshore wind has received positive feedback from fishermen in the North East because turbines create artificial reef structures that enhance biodiversity of fish and filter feeders, enhancing the recreational and commercial fishing industries.
A seven-year-long study, the first of its kind in the United States, titled, “Demersal fish and invertebrate catches relative to construction and operation of North America’s first offshore wind farm,” was published in the International Council for the Exploration of the Sea (ICES)’s Journal of Marine Science on March 29, 2022. The researchers found that there was no significant negative effect on fish that live near the bottom of the sea – demersal fish – and invertebrate populations during Block Island’s construction and operation.
Along the east coast, 11 states (Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Delaware, Maryland, Virginia, and North Carolina) have joined the Fisheries Mitigation Project. This project serves as a common framework across east coast states to anticipate and avoid impacts on fisheries and provide financial compensation for any acquired economic impact related to offshore wind development.

Strict permitting ensures bird and avian safety by adhering to laws like the Endangered Species Act and the Migratory Bird Treaty Act. While wind turbines can impact some bird populations, evolving turbine technology now includes radar systems to detect and protect avian species. These systems can warn birds of collision risks, automatically stop turbines, and monitor bird and bat behavior, providing real-time updates to reduce wildlife impacts.
Additionally, while the impact of wind turbines may lead to bird and bat mortality, the numbers are relatively small compared with other common threats. For example, cats are estimated to kill 2.4 million birds per year, and collisions with glass buildings cause around 599 million bird deaths annually, while wind turbines account for approximately 234,000 bird deaths per year. From a broader perspective, climate change poses a significant threat, putting about two-thirds of North American bird species at increased risk of extinction.

Wind turbines generate relatively little waste during operation. Most waste occurs at the end of their life, usually after 20–30 years, and includes components like blades, metal, and electronics. Many materials, such as steel and copper, can be easily recycled. Turbine blades, often made from composite materials like carbon fiber and fiberglass, are more challenging to recycle, but new programs and processes are emerging to repurpose or recycle them. According to the U.S. Department of Energy, 85–90% of a wind turbine consists of materials that can currently be commercially recycled.

Wind projects can reduce wildlife impacts through careful planning, technology, and ongoing monitoring. Developers can select sites that avoid key habitats, migration corridors, and nesting or breeding areas, and they typically conduct wildlife studies before construction to understand local species and patterns. Once operating, turbines can be slowed or temporarily shut down during periods when birds or bats are most active, and emerging tools—such as detection sensors, cameras, and acoustic or visual deterrents—can help identify or discourage wildlife from approaching turbines. In addition, timing construction to avoid sensitive seasons and planning for responsible decommissioning help minimize impacts throughout the project’s full lifespan.

Noise from wind turbines is generally low and unlikely to cause harm. For example, an Environmental Impact Statement for a 120-turbine, 500-MW project concluded that operational noise would likely remain below 55 decibels (dBA)—about the level of a quiet conversation or a refrigerator humming. For context, a soft whisper is roughly 30 dBA, and the Centers for Disease Control and Prevention (CDC) identifies 70 dBA as the threshold for prolonged exposure that could lead to annoyance or potential hearing issues. Even directly beneath a turbine, two people can comfortably converse at normal volume.
Research from the Lawrence Berkeley National Laboratory showed that 92% of residents living within five miles of a wind turbine report either positive or neutral experiences.
Continued technological improvements are expected to make wind turbine operations even quieter in the future.

Yes, crop duster pilots are among the most skilled professionals in aviation. With extensive training in low-altitude flying, they expertly maneuver around obstacles such as power lines, trees, irrigation systems, and even unpredictable weather. Wind turbines, while tall, are simply another feature of the landscape for pilots. Additionally, Federal Aviation Administration regulations implemented in 2019 require any towers over 50 feet to be clearly marked, significantly improving safety for pilots. With advanced GPS systems and precision-flying techniques, crop dusters adapt to wind turbines, ensuring uninterrupted farming operations.

The military has a well-established and rigorous process for ensuring that wind development occurs in a manner that is compatible with military operations. The Department of Defense (DoD) Siting Clearinghouse examines and analyzes each proposed wind farm, and includes participation from all five military branches. Federal law allows DoD to raise concerns if a proposed energy project, individually or on a cumulative basis, may adversely impact military readiness or operations.

A wind turbine makes electricity by using the power of the wind. Wind turns the turbine’s blades, which spin a shaft connected to a generator. That generator then produces electricity that can be sent to the grid to power homes and businesses.
Source(s): https://www.energy.gov/eere/wind/how-do-wind-turbines-work + https://www.britannica.com/technology/wind-turbine
The turbines in a wind farm are connected so the electricity they generate can travel from the wind farm to the power grid. Once wind energy is on the main power grid, electric utilities or power operators will send the electricity to where people need it. Smaller transmission lines, called distribution lines, collect electricity generated at the wind project and transport it to larger “network” transmission lines, where the electricity can travel across long distances to the locations where it is needed. Finally, smaller distribution lines deliver electricity directly to your town, home, or business.
A typical modern turbine will start to generate electricity when wind speeds reach six to nine miles per hour (mph), known as the cut-in speed. Turbines will shut down if the wind is blowing too hard (roughly 55 miles an hour) to prevent equipment damage. Over the course of a year, modern turbines can generate usable amounts of electricity over 90% of the time. For example, if the wind at a turbine reaches the cut-in speed of six to nine mph, the turbine will start generating electricity. As wind speeds increase, so does electricity production.

Both onshore and offshore turbines have built-in mechanisms to lock or feather the blades (reduce the surface area pointing into the wind) when wind speeds are excessive. These mechanisms have proven successful in the nation’s first offshore wind farm in Block Island, Rhode Island.
If you notice smoke, fire, or any immediate danger at a battery energy storage system site, call 911 immediately. For non-emergency concerns, you can contact your local fire department or county emergency management office, which will coordinate with the project operator. Some battery energy storage system sites may also post a contact number for the facility owner or operator; you can check the signage at the site or visit your local government’s permitting office website for this information.
Battery energy storage systems can directly benefit communities by enhancing resilience and reliability. They store electricity and can supply power when the main grid fails, helping communities stay powered during natural disasters. For example, the Hot Springs Microgrid in Hot Springs, North Carolina, built in 2023 by Duke Energy with solar panels and lithium-ion batteries, activated during Hurricane Helene in October 2024. After flooding disabled the town’s substation, the microgrid restored power and ran continuously for approximately 143.5 hours, keeping the community operational.

Battery energy storage systems generate most of their waste at the end of the battery’s life, typically after 10–15 years for lithium-ion batteries. This includes used battery cells, metals like lithium, cobalt, nickel, and plastics. Many components can be recycled or repurposed, though recycling processes are still developing and not yet available everywhere. Proper disposal and recycling are important to minimize environmental impacts.

Yes. Battery energy storage systems operate much like the batteries in your phone or laptop, but on a much larger scale. They are regulated by strict national, state, and local standards to ensure safe design and operation. Key requirements include the National Fire Protection Association’s NFPA 855 standard for installation and the Underwriters Laboratories’ UL 9540 standard for system safety testing and certification. Local fire marshals and building departments are responsible for enforcing these codes so that facilities are permitted, built, and operated with safety in mind.

Although uncommon, battery energy storage systems comprised of lithium-ion cells can sometimes catch fire again or reignite long after being damaged or involved in a fire, hours, days, or even weeks later. That’s why monitoring and safety measures remain important even after a fire appears to be out or has been extinguished.

Energy storage is transforming how electricity is generated, delivered, and used. Battery energy storage systems offer several key benefits:
1. Increase grid flexibility, allowing for greater integration of variable solar and wind energy.
2. Provide backup power during emergencies such as storms, equipment failures, or outages.
3. Reduce costs by storing electricity when it’s inexpensive and supplying it during periods of high demand.
4. Instantly balance supply and demand, enhancing the grid’s reliability, resilience, efficiency, and environmental performance.

It depends on who has an agreement to buy the energy. Electricity from a solar or wind project is fed into the grid and can serve local communities, a specific company or “offtaker,” or customers in other states or regional markets.
In North Carolina, many solar and wind projects are owned by independent power producers that sell their output to utilities such as Duke Energy Carolinas or Duke Energy Progress through power purchase agreements (PPAs) – a financial agreement where a developer installs a project and sells the power at a fixed rate. These projects connect to the utilities’ transmission lines and help serve customers in their territories. Utilities may also own renewable projects directly and use the power to serve their own customers.
A portion of North Carolina is located in the PJM wholesale electricity market, where projects can sell energy that is then delivered across the PJM region. In this area, private buyers—including companies like Amazon—may also enter power purchase agreements with project owners. In those cases, the energy can be produced on-site for the buyer or delivered to them through the grid.
In South Carolina, electricity from solar or wind projects typically serves customers in the territories of Duke Energy Carolinas, Duke Energy Progress, Dominion Energy South Carolina, or the state-owned utility Santee Cooper. Independent power producers may sell energy to these utilities under PPAs, while utilities may also own renewable projects themselves.
South Carolina also allows certain large commercial or industrial customers to purchase renewable energy through utility-facilitated programs or PPAs, depending on the utility and regulatory approval. In all cases, the energy is delivered through the grid, even when a company is the designated buyer.

Utilities study multiple route options and conduct environmental reviews to assess impacts on wildlife, water, and communities. Under the National Environmental Policy Act (NEPA), federal agencies require these assessments before approving a project. Reviews can include Environmental Assessments (EAs), Environmental Impact Statements (EIS), and consultations with agencies like the U.S. Fish and Wildlife Service and the Army Corps of Engineers.

Transmission planning is usually led by utilities, regional transmission organizations (RTOs), and independent system operators (ISOs). They study where new lines are needed to ensure reliability, meet growing electricity demand, and integrate renewable energy. State regulators and public utilities commissions review and approve plans, and the public can often provide input during the process. In North Carolina and South Carolina, however, there is no RTO or ISO overseeing transmission planning. Instead, vertically integrated utilities such as Duke Energy and Dominion Energy handle most of the planning directly, subject to oversight by the North Carolina Utilities Commission and the Public Service Commission of South Carolina. This means transmission decisions in the Carolinas are more utility-driven compared to states within organized markets, though regulators still play a key role in reviewing projects and ensuring they meet public needs.

New transmission lines usually need approval at the federal, state, and local levels. Federal agencies (e.g. the U.S. Department of Energy and the Federal Energy Regulatory Commission (FERC)) review projects on federal land or with federal funding. State public utility commissions check if the project is needed and cost-effective. Local governments handle zoning and construction permits. Environmental reviews and public input are also required to make sure communities and ecosystems are protected.
