Energy innovation is important because it has the power to enhance economic growth, support energy independence, and improve the health and well-being of the American people.
For these reasons, the U.S. Department of Energy''s Office of Energy Efficiency and Renewable Energy (EERE) is committed to leading the nation''s transition to a resilient energy economy.
Renewable energy resources provide an affordable, reliable, and sustainable U.S. power supply while reducing the country''s greenhouse gas emissions.
To reduce our reliance on fossil fuels, we can harness abundant domestic resources, includingwind energy,solar energy,bioenergy,geothermal energy,hydropower, andmarine energy.
About 20% of all U.S. electricity now comes from renewable energy sources, 60% from fossil fuels like coal, petroleum, and natural gas, and the remainder from nuclear energy.
Renewable power is not only cost-competitive; it''s also the most cost-effective source of energy in many situations, depending on the location and season.
Still, we have more work to do both on the technologies themselves and on our nation''s electric system as a whole to achieve the U.S. climate goal of 100% carbon-pollution-free electricity by 2035.
EERE''s job is to give Americans access to the energy resources they want at a price they can afford with the infrastructure they can count on.
Learn more about why EERE believes in bringing energy and efficiency improvements to the American people:
We need American-made energy technologies to provide the fastest, most effective, and most lucrative pathway to a sustainable power supply.
Transitioning to a resilient energy economy requires a transformative commitment to prioritizing disadvantaged and underserved communities.
Adopting renewable energy in the United States reduces the need to rely on other countries for energy resources and technologies, while also helping isolated communities support their own energy needs.
Using more renewable energy resources—solar, water, wind, geothermal, and bioenergy—and energy storage gives us more ways to keep the power on or restore it after an outage.
Transitioning to renewable energy reduces air pollution, improving public healthand lowering healthcare costs.
Advancing renewable-energy, energy-efficient, and sustainable-transportation technologies willtransform U.S. communitiesand spur economic opportunity.
Renewable energy research, innovation, and deployment creates jobs and supports the growth of American businesses.
Providing all Americans with affordable energy, especially those in underserved and low-income communities, has an immediate and tangible impact on daily lives.
EERE is helping communities define their own priorities—whether greater affordability, reduced power outages, sustainable job creation, cleaner air, or other unique requirements—and leverage energy solutions to meet their needs.
Diversifying the clean energy workforce and science, technology, engineering and mathematics (STEM) introduces a wider variety of perspectives that support greater innovation and American competitiveness.

It''s a common misconception that renewable energy, clean energy, and green energy all mean the same thing. While there is some overlap, each term has a unique meaning. For instance, while green energy sources are all considered renewable, not all renewable energy sources can be considered green. Moreover, clean energy encompasses nuclear energy, which is neither green nor renewable.
Some clarification is needed if we are to use sustainable energy sources to tackle the challenges ahead of us in the race against climate change. This article will explain the similarities and differences between green, clean, and renewable energy sources so you can become a more conscious consumer of environmental news, information, and policy.
Renewable energy is any energy source that constantly replenishes itself over a relatively short time frame.
In theory, renewable energy is considered virtually inexhaustible, meaning the method used to produce electricity never runs out. This makes it a more viable long-term option compared to natural gas and coal, both of which are non-renewable resources that we have a finite supply of.
While green energy is renewable, not all renewable energy sources can be considered green. For example, the construction of a large-scale hydropower facility can have a heavy environmental impact on nearby rivers and lakes. Even so, since green energy sources do not release significant amounts of greenhouse gases into the atmosphere during the generation of electricity, they are considered clean energy resources.
Clean energy is any energy source that emits negligible pollution, greenhouse gases, or chemical contaminants.
The "clean" means these sources have minimal or zero impact on the surrounding environment, which makes them ideal for the long-term survivability of the planet.
These three terms — green, renewable, and clean energy — are often used interchangeably in eco-friendly content, but they don't always mean the same thing. While some overlap exists, the subtle differences and nuances can impact funding, allocation, and the creation of government credits during and after the production of these sustainable energy sources.
Thus, it''s important to understand that the true definitions of renewable, clean, and green energy depend upon how they''re created, how they''re refreshed, and their overall environmental impact.
In theory, renewable energy is inexhaustible as it's a continuous energy source. However, renewable energy is not always clean, and that cleanliness depends on a given state or nation's laws and parameters for clean power.
For example, some renewable sources emit pollutants while staying within the threshold of a legal definition of "clean." The cleanest renewable sources are wind energy, geothermal energy, and solar energy. However, while small hydro plants are renewable and clean, large hydroelectric plants emit some pollutants and can harm the environment during construction. Hence, they create renewable but not clean energy.
