Education Resources Information Center: A Guide to Finding Education Research

The Education Resources Information Center (ERIC) is an online research database focused on education. Sponsored by the U.S. Department of Education’s Institute of Education Sciences, ERIC helps students, educators, researchers, policymakers, and the public find information on teaching, learning, and education policy.

What You Can Find in ERIC

ERIC indexes a wide range of education-related materials, including journal articles, research reports, conference papers, policy documents, and other publications. Its collection covers topics from early childhood education and literacy to higher education, special education, assessment, and school leadership.

Some records link to full-text documents, while others provide a citation and abstract. When full text is not available through ERIC, the record may still help readers identify a publication to locate through a library, publisher, or other source.

How to Search the Database

Visitors can search ERIC using keywords, titles, authors, or publication details. Filters can help narrow results by publication date, source type, education level, and other characteristics. Users can also limit results to peer-reviewed materials or records with full text available, when those options are relevant.

For more focused results, start with a specific question and choose a few precise search terms. For example, someone researching reading instruction in elementary school might search for “elementary reading instruction” and then refine the results by date or publication type. ERIC’s education-specific vocabulary can also help users discover related terms and broaden a search.

Who Uses ERIC?

  • Teachers and school leaders can explore research and resources related to classroom practice and school improvement.
  • Students and researchers can use the database to find sources for assignments, literature reviews, and research projects.
  • Policymakers and administrators can investigate evidence and publications related to education programs and policy.
  • Families and community members can learn more about education topics and locate information from research and practice.

Using ERIC Effectively

ERIC is a discovery tool, so readers should review each record carefully and consider the source, publication date, research methods, and intended audience. A database listing does not by itself mean that a study’s findings apply to every school or situation. Comparing multiple sources can provide a fuller picture of what the evidence suggests.

Whether you are beginning a research project or looking for evidence on a specific education question, ERIC offers a practical starting point. Its searchable collection can make education research easier to discover and help users connect with information that supports informed learning, teaching, and decision-making.

Renewable and Nonrenewable Energy: What’s the Difference?

Energy powers homes, businesses, transportation, and industry. The sources used to produce it are often grouped into two categories: renewable and nonrenewable. Understanding the difference helps explain how energy choices affect the environment, the economy, and long-term energy security.

What Is Renewable Energy?

Renewable energy comes from sources that are naturally replenished on a human timescale. Common examples include sunlight, wind, flowing water, heat from within the Earth, and organic material known as biomass.

  • Solar energy uses sunlight to generate electricity or heat.
  • Wind energy uses turbines to convert moving air into electricity.
  • Hydropower generates electricity from moving or falling water.
  • Geothermal energy draws on heat from beneath Earth’s surface.
  • Biomass energy comes from plant material and other organic matter.

Renewable sources generally produce fewer greenhouse gas emissions during operation than fossil fuels. They can also help diversify energy supplies. However, some renewables depend on weather or location. Solar panels produce less electricity at night, for example, and wind turbines need sufficient wind. Energy storage, transmission lines, and a mix of different power sources can help address these challenges.

What Is Nonrenewable Energy?

Nonrenewable energy comes from resources that are limited or take millions of years to form. Once used, these resources cannot be replaced quickly enough to meet current demand. The main examples are coal, oil, and natural gas. Nuclear energy is also commonly classified as nonrenewable because it relies on finite fuels such as uranium, even though it produces electricity without burning fossil fuels.

Fossil fuels have long supplied a large share of the world’s energy. They are energy-dense and can be stored and transported, making them useful for electricity generation, heating, and transportation. But extracting and burning them can cause air and water pollution and release greenhouse gases that contribute to climate change. Nuclear power produces low-carbon electricity during operation, but it requires careful management of radioactive materials and safety risks.

Comparing the Two

The central difference is how quickly each source is replenished. Sunlight, wind, and flowing water are continually renewed by natural processes. Coal, oil, natural gas, and uranium exist in finite quantities or take extremely long periods to replace.

Renewable does not automatically mean impact-free. Renewable energy projects can affect wildlife, land, waterways, and nearby communities. Likewise, nonrenewable sources differ from one another: the environmental and safety concerns associated with coal are not identical to those associated with natural gas or nuclear power. Careful planning and strong environmental safeguards matter for every energy source.

Why the Energy Mix Matters

No single energy source meets every need in every place. A reliable energy system may combine renewables, energy storage, transmission, efficiency measures, and other sources of dependable power. The best mix depends on local resources, infrastructure, costs, environmental priorities, and community needs.

Renewable and nonrenewable energy are not just technical categories; they represent different choices about how society produces and uses power. Improving energy efficiency, expanding cleaner sources, and planning responsibly for existing energy resources can all contribute to a more reliable and sustainable energy future.

 

8 Essential Tips for Balancing Renewable and Nonrenewable Energy Use

  1. Choose renewable energy like solar and wind when possible.
  2. Use less electricity to reduce reliance on all energy sources.
  3. Renewable resources can naturally replenish over time.
  4. Nonrenewable resources, like coal and oil, are limited.
  5. Save energy by turning off unused lights and devices.
  6. Consider biking, walking, or public transit to use less fuel.
  7. Support clean energy programs in your community.
  8. Recycle materials to reduce the energy needed to make new products.

Choose renewable energy like solar and wind when possible.

Choose renewable energy sources like solar and wind whenever possible. Unlike coal, oil, and natural gas, these resources are naturally replenished and generate electricity with little to no greenhouse gas emissions during operation. Switching to renewable power—at home, at work, or through a utility’s clean-energy plan—can help reduce pollution and support a more sustainable energy future.

Use less electricity to reduce reliance on all energy sources.

Using less electricity is a simple way to reduce demand for both renewable and nonrenewable energy. Turn off lights and electronics when they’re not in use, choose energy-efficient appliances, and adjust heating and cooling to avoid waste. Lower electricity use can reduce fuel consumption and emissions, ease pressure on the power grid, and help conserve resources regardless of how the electricity is generated.

Renewable resources can naturally replenish over time.

Renewable resources can naturally replenish over time, making them a more sustainable option when managed responsibly. Sunlight, wind, and flowing water are examples of resources that are continually renewed by natural processes, unlike finite resources such as coal, oil, and natural gas. While renewable resources can still have environmental impacts, using them wisely can help conserve limited fuels and support a cleaner energy future.

Nonrenewable resources, like coal and oil, are limited.

Nonrenewable resources, like coal and oil, are limited because they take millions of years to form and are used much faster than nature can replace them. As supplies decline, these fuels may become harder and more expensive to obtain. Burning them also releases pollution and greenhouse gases, so using energy efficiently and developing renewable alternatives can help conserve resources and reduce environmental impacts.

Save energy by turning off unused lights and devices.

Save energy—and reduce your impact on the environment—by turning off lights and devices when you’re not using them. Switch off lamps when leaving a room, unplug chargers and small appliances when practical, and enable sleep or energy-saving settings on computers and TVs. These simple habits can lower electricity use, help reduce utility bills, and limit the need to generate power from both renewable and nonrenewable sources.

Consider biking, walking, or public transit to use less fuel.

Choosing to bike, walk, or take public transit can reduce the amount of gasoline and diesel used for everyday travel. These fuels are nonrenewable resources, so using less helps conserve them and can also lower greenhouse gas emissions and air pollution. For short trips, try walking or biking when it’s safe and practical; for longer journeys, public transit can be an efficient alternative to driving alone.

Support clean energy programs in your community.

Support clean energy programs in your community by learning about local options and getting involved. You might attend a town meeting, support renewable energy projects, or ask local leaders about programs that help residents and businesses use solar, wind, or other cleaner power. Community efforts can make clean energy more accessible, reduce reliance on nonrenewable resources such as coal, oil, and natural gas, and help build a healthier, more resilient future.

Recycle materials to reduce the energy needed to make new products.

Recycling materials can reduce the energy needed to make new products from raw resources. For example, producing items from recycled aluminum typically takes much less energy than making them from newly mined ore. By sorting and recycling paper, glass, metals, and accepted plastics, households and businesses can help conserve energy, reduce waste, and limit demand for nonrenewable resources such as coal, oil, and natural gas. Check local recycling guidelines to make sure materials are prepared correctly.

Renewable Natural Gas: Turning Organic Waste Into Energy

Renewable Natural Gas: Turning Organic Waste Into Energy

Renewable natural gas (RNG), also called biomethane, is a fuel made by capturing and processing methane produced when organic materials break down. It can be used in many of the same ways as conventional natural gas, including for heating, electricity generation, and transportation. Its potential climate benefits depend on how it is produced, how much methane escapes, and what energy source it replaces.

How renewable natural gas is made

RNG begins with organic material, or biomass, such as livestock manure, food scraps, wastewater sludge, and the gas produced at landfills. As this material decomposes without oxygen, microorganisms create biogas—a mixture that typically contains methane, carbon dioxide, water vapor, and other compounds.

Biogas can be used directly in some applications, but it must be cleaned and upgraded to become RNG. Processing removes much of the carbon dioxide, moisture, and contaminants. The resulting gas is mostly methane and can be conditioned to meet applicable standards for use in pipelines or equipment designed for natural gas.

Common sources include:

  • Landfills: Gas formed as buried waste decomposes can be captured through wells and collection systems.
  • Dairy and livestock farms: Manure can be processed in sealed anaerobic digesters, which capture biogas as the waste breaks down.
  • Wastewater treatment plants: Digesters can produce biogas from sewage solids and other organic material.
  • Food-waste facilities: Food scraps and processing residues can be digested to produce biogas.

How RNG is used

Once upgraded, RNG can be injected into a natural gas pipeline if it meets the pipeline’s quality requirements. It can then be used for building heat, industrial processes, power generation, or as a transportation fuel. Some projects use the gas near where it is produced, while others connect it to a pipeline for delivery elsewhere.

Because RNG can use existing gas infrastructure and equipment, it may be easier to incorporate into some systems than fuels that require entirely new networks. That compatibility does not mean every project is simple: connecting to a pipeline, meeting gas specifications, and transporting the fuel can require substantial investment.

Potential climate and community benefits

Capturing methane that would otherwise escape from a landfill or manure-management system can reduce the release of a potent greenhouse gas. When RNG displaces fossil natural gas or another fuel, it may also lower emissions over the full lifecycle, depending on the project and the fuel being replaced.

RNG projects may provide additional local benefits. They can help manage organic waste, reduce some odors, and create revenue for farms or waste facilities. At wastewater plants and landfills, gas recovery can turn a byproduct into a usable energy source.

These benefits are not automatic. The climate impact depends on factors such as how the feedstock is collected, the energy used to process it, gas losses throughout the system, and what would have happened to the organic material without the project. For example, a system that prevents methane from escaping can have a different emissions profile from one that relies on purpose-grown crops.

Challenges and considerations

Methane leaks are a central concern. If methane escapes during production, upgrading, storage, or transport, it can reduce or even undermine the climate advantage of a project. Effective leak detection, equipment maintenance, and transparent emissions monitoring are therefore important.

RNG is also limited by the amount and location of suitable organic waste. Projects need a dependable supply of feedstock, as well as nearby infrastructure or users for the gas. In some cases, the cost of collection, processing, and pipeline connection can be high.

Another important distinction is between waste-based RNG and gas made from energy crops. Using manure, landfill gas, or food waste can address existing waste streams. Growing crops specifically for fuel raises additional questions about land use, water, fertilizer, and competition with food production. Those impacts should be considered when evaluating a project.

How to evaluate an RNG project

Useful questions include:

  • What materials are used to produce the gas?
  • What would happen to those materials if the project did not exist?
  • How are methane leaks measured and controlled?
  • How much energy is used to collect and process the gas?
  • What fuel or energy source does the RNG replace?
  • Are emissions estimates based on a transparent lifecycle analysis?

The role of renewable natural gas

Renewable natural gas can be one tool for managing organic waste and reducing methane emissions, particularly where methane would otherwise be released. It is not a limitless resource or a universal substitute for fossil fuels. Its value depends on responsible feedstock choices, careful emissions controls, and a clear accounting of its full environmental impact.

As communities and industries consider ways to reduce emissions, RNG is best assessed alongside other options, including energy efficiency, electrification, renewable electricity, and improved waste prevention. Comparing these choices on a project-by-project basis can help identify where RNG offers the greatest practical benefit.

 

Understanding Renewable Natural Gas: Key Questions and Answers

  1. What is renewable natural gas (RNG)?
  2. How is renewable natural gas made?
  3. What can renewable natural gas be used for?
  4. How is renewable natural gas different from conventional natural gas?
  5. Is renewable natural gas better for the environment?
  6. Can renewable natural gas be used in existing natural gas pipelines and appliances?

What is renewable natural gas (RNG)?

Renewable natural gas (RNG), also called biomethane, is a methane-rich fuel made by capturing biogas from decomposing organic materials such as food waste, manure, wastewater, and landfill waste. The biogas is cleaned to remove carbon dioxide, moisture, and other impurities so it can be used in applications similar to conventional natural gas, including heating, electricity generation, and transportation.

How is renewable natural gas made?

Renewable natural gas (RNG) is made by capturing biogas produced as organic materials—such as food waste, livestock manure, wastewater, or landfill waste—break down. The biogas is then cleaned and upgraded to remove carbon dioxide, moisture, and other impurities, leaving a methane-rich gas that can meet standards for use in natural gas pipelines, heating, electricity generation, or transportation.

What can renewable natural gas be used for?

Renewable natural gas can be used much like conventional natural gas. After it is cleaned and upgraded, it can be delivered through compatible pipelines and used for heating buildings, cooking, generating electricity, powering industrial equipment, or fueling vehicles designed to run on natural gas. Its best use depends on local infrastructure, the source of the gas, and which energy source it replaces.

How is renewable natural gas different from conventional natural gas?

Renewable natural gas (RNG) and conventional natural gas are both made mostly of methane and can be used in many of the same appliances, vehicles, and pipelines. The main difference is their source: conventional natural gas is extracted from underground fossil fuel deposits, while RNG is produced by capturing and cleaning biogas from organic materials such as food waste, manure, wastewater, or landfill waste. Because RNG can make use of methane that might otherwise escape into the atmosphere, it may reduce greenhouse gas emissions compared with conventional natural gas—but the overall benefit depends on how the RNG is produced, whether methane leaks during processing and transport, and which fuel it replaces.

Is renewable natural gas better for the environment?

Renewable natural gas can be better for the environment when it captures methane from sources such as landfills, manure, or wastewater that would otherwise release it into the atmosphere, and when it replaces fossil fuel with minimal leakage during production and delivery. Its overall impact varies, however, depending on the feedstock, processing energy, methane leaks, and the fuel it displaces. RNG is not automatically carbon-neutral or impact-free, so projects should be evaluated using transparent, full-lifecycle emissions data.

Can renewable natural gas be used in existing natural gas pipelines and appliances?

Yes. Renewable natural gas (RNG) can often be used in existing natural gas pipelines and appliances after it is cleaned and upgraded to meet the pipeline’s gas-quality standards. Because properly processed RNG has properties similar to conventional natural gas, it can typically travel through compatible pipelines and be used in many existing furnaces, stoves, and other natural-gas equipment. Requirements vary by utility and location, so RNG must meet local specifications before it can be injected into a pipeline.
