These advancements are essential for integrating solar power seamlessly into the energy grid and making it a reliable energy source.

3. Market Dynamics and Regional Leadership

  • 3-1. Texas' leadership in solar installations

  • Texas has established itself as a dominant leader in the solar energy sector. According to a new report, solar generation in Texas outpaced coal-fired power plants for the first time, contributing 3.26 million megawatt-hours (MWh) to the Texas power grid. In 2023, Texas installed over 6,500 megawatts of solar generation, surpassing California for the second consecutive year. The U.S. Energy Information Administration (EIA) projects that Texas will continue to lead new utility-scale solar capacity, accounting for 35 percent of the expected 62.8 gigawatts of new solar capacity in 2024. Texas had more than $27 billion in solar energy investment in the fourth quarter of 2023, with key projects including Elin Energy's 225,000-square-foot manufacturing facility in Waller County and SEG Solar’s PV module manufacturing plant in Harris County.

  • 3-2. Renewable Energy Certificates (RECs)

  • Renewable Energy Certificates (RECs), also known as Green tags or Tradable Renewable Certificates (TRCs), are tradable, non-tangible certificates in the United States that confirm the generation of 1 megawatt-hour (MWh) of electricity from a renewable energy source. RECs are essential for meeting Renewable Portfolio Standards that exist in 29 U.S. states, the District of Columbia, and Puerto Rico. Electric companies in these regions must supply a certain percentage of their electricity from renewable sources by purchasing RECs. Additionally, customers can buy RECs voluntarily to support renewable energy usage.

  • 3-3. Investment surges in solar projects

  • The United States experienced a significant surge in investment in solar projects in 2023, driven by federal policies like the Inflation Reduction Act (IRA). A record $303.3 billion in energy transition financing was deployed across clean energy technologies, including solar, in 2023. The number of planned manufacturing facilities rose to 104, with 34 of these dedicated to solar. Furthermore, 42 gigawatts of new renewable power-generating capacity were added, led by robust solar additions. In Texas, major investments included initiatives such as phase two of the Sunnyside Solar Farm and Lightsource's development of two new solar farms powered by a $348 million financing package.

4. Economic Impact and Employment

  • 4-1. Growth of the Solar Industry

  • The growth of the solar industry in the United States has been remarkable over the past decade. Solar has experienced an average annual growth rate of 24% in the past decade due to the federal tax credit, decreasing costs to install solar, and greater demand for clean energy among the private and public sectors. Since the enactment of the Solar Investment Tax Credit (ITC) in 2006, the industry has expanded by 200 times. As of now, the amount of solar currently installed in the U.S. is 162 gigawatts (GW), which is capable of powering nearly 30 million homes.

  • 4-2. Employment Statistics

  • The solar industry is a significant contributor to employment in the United States. Nearly 300,000 Americans are employed in solar at more than 10,000 companies across the nation. These employees work in various roles including installation, development, manufacturing, sales and distribution, and operations and maintenance.

  • 4-3. Economic Contributions

  • The economic contributions of the solar industry are substantial. In 2022, the value of the U.S. solar market was $36.3 billion. The industry generated more than $36 billion of private investment in the American economy. This investment has led to lower greenhouse gas emissions, better energy reliability, reduced costs, and continuous economic growth. Solar energy currently accounts for over 5% of U.S. electricity generation, marking nearly an elevenfold increase over the past decade.

5. Policy Support and Regulatory Environment

  • 5-1. Renewable Portfolio Standards (RPS)

  • A Renewable Portfolio Standard (RPS) is a regulation that mandates electricity supply companies to produce a specified fraction of their electricity from renewable energy sources like wind, solar, biomass, and geothermal. As of August 2022, 38 of the 50 U.S. states and the District of Columbia have adopted RPS. The federal version of RPS, known as the Renewable Electricity Standard (RES), focuses on encouraging the production of renewable energy. Different states also have clean energy standards that include resources producing no emissions, such as large hydropower and nuclear power. Through RPS, certified renewable energy generators earn certificates for every unit of electricity generated, which can be sold to supply companies. These supply companies then use the certificates to demonstrate compliance with regulatory obligations. RPS programs generally rely on the private market for implementation and promote price competition between different types of renewable energy.

  • 5-2. State and Federal incentives

  • Both state and federal governments provide various incentives to encourage the production and use of renewable energy. At the federal level, the Renewable Electricity Standard (RES) serves as the cornerstone policy to drive renewable energy generation. Beyond RES, various tax credits, grants, and rebates are available to incentivize businesses and homeowners to adopt renewable technologies. At the state level, incentives can vary widely but often include subsidies, rebates, and specific financial incentives for renewable energy installations. These incentives play a pivotal role in promoting renewable energy infrastructure and mainstream adoption.

  • 5-3. Role of non-profit organizations

  • Non-profit organizations are instrumental in advancing renewable energy initiatives in the United States. The American Council on Renewable Energy (ACORE), headquartered in Washington, D.C., stands out as a significant entity. Founded in 2001, ACORE serves as a unifying body promoting the growth and mainstream integration of renewable energy in the U.S. With over 700 member organizations as of 2010, ACORE has published key reports such as the ‘Outlook On Renewable Energy In America,’ which highlights the progress and future potential of renewable energy in the country. Non-profits like ACORE facilitate collaboration, education, and policy advocacy, thereby bolstering the renewable energy sector’s development.
