Biden’s Solar and Decarbonization Goals
President Biden’s climate and energy agenda lays out transformative targets intended to position the United States as a global leader in clean energy deployment, with solar power holding the most ambitious share.
- Reduce U.S. greenhouse gas emissions by 50–52% below 2005 levels by 2030.
- Achieve carbon pollution-free electricity by 2035—meaning all U.S. power generation comes from zero-emission sources within just over a decade.
- Reach net-zero greenhouse gas emissions economy-wide by 2050.
- Ensure at least 40% of climate investment benefits flow to disadvantaged communities, addressing environmental justice and energy equity.
To accomplish these targets, solar energy is expected to grow extraordinarily fast—rising from about 3-5% of current electricity generation to approximately 40% by 2035 and potentially 45% or more by 2050. The administration’s goals require rapid upscaling, deployment of new technology, and sweeping policy action across the energy sector.
Technology and Economics of Solar Expansion
Solar power has become the cheapest and fastest-growing source of electricity in the U.S. and globally, thanks to spectacular falls in the cost of photovoltaic (PV) panels, improvements in efficiency, and streamlined installation practices.
- Solar’s share of American electricity has grown from less than 1% a decade ago to about 3–5% today, with growth accelerating in recent years.
- The Department of Energy’s 2021 Solar Futures Study concluded the U.S. must install an average of 30 GW of solar capacity per year between now and 2025—double the current annual rate—and 60 GW per year from 2025 to 2030.
- This rollout translates to 1,000 GW (gigawatts) of solar in operation by 2035 for a renewable-dominated grid, and up to 1,600 GW by 2050 on a zero-carbon grid.
- By midcentury, decarbonizing transportation, buildings, and industry might require as much as 3,000 GW of solar capacity, underscoring the vast scale of future energy demand shifts.
Despite this progress, reaching the Biden targets requires quadrupling annual installations over the next decade. Exponential growth—enabled by both utility-scale and rooftop deployments—would require massive expansion in U.S. supply chains, workforce, financing, and grid infrastructure.
Policy Levers and Legislative Actions
Turning the promise of solar into reality depends on leveraging a suite of federal policies, incentives, and investments. Some key Biden administration policy actions include:
- Inflation Reduction Act (IRA): Historic tax credits for clean electricity, including production and investment credits, to catalyze solar, wind, and battery storage deployment.
- Bipartisan Infrastructure Law: Billions for power grid upgrades, transmission expansion, and research on clean energy technologies.
- Production Tax Credit and Investment Tax Credit: Incentivizing not just the installation but domestic manufacturing of solar components, supporting U.S. supply chain independence and job creation.
- Defense Production Act invocation for key components: To accelerate the production of solar panels and grid technologies on U.S. soil, reducing reliance on imports.
- Grid Modernization Programs: Financing over 5,000 new miles of transmission lines, supporting interregional connections, and targeting resilience to climate extremes.
- Permitting Reform and Public Land Deployment: Fast-tracking clean energy projects on federal lands, with more than 40 projects approved and a target of 25 GW by 2025.
- Community and Residential Solar Incentives: Directing funds and technical support to help disadvantaged and rural communities adopt local solar and distributed energy resources.
Abigail Ross Hopper, head of the Solar Energy Industries Association, has underscored that ambitious government policies—backed by private sector determination—are essential to overcome current barriers and achieve the administration’s solar expansion goals.
The Supply Chain and Manufacturing Challenge
The Biden solar plan faces significant supply chain bottlenecks and labor force needs:
- Tariffs and trade disputes (especially with China, the world’s dominant supplier of solar panels) threaten affordability and speed of deployment.
- Shortages of raw materials (steel, aluminum, polysilicon) and price spikes have driven up costs of solar installations in recent years.
- Efforts to spur domestic manufacturing include tax credits for made-in-America components and federal investments in new factories, but ramping up U.S. production capacity will take time.
- Resilience concerns for the entire solar supply chain require investments in recycling infrastructure, local component manufacture, and transparent labor/social standards.
- Building out the workforce capable of designing, installing, and maintaining solar infrastructure will require comprehensive job training and education programs.
Equity, Jobs, and Opportunities in a Clean Energy Economy
A solar revolution promises not just lower carbon emissions, but broad-based economic and social benefits—if the right policies are in place. The Biden administration’s plan foregrounds equity and good jobs as core outcomes.
- Job Creation: The DOE estimates up to 1.5 million Americans could be employed in the solar sector by 2035—a manifold increase from today, with opportunities across manufacturing, installation, research, and grid services.
- Electricity Cost Reductions: Cheap clean power reduces utility bills, with especially large benefits for low-income households if solar access initiatives are equitably designed.
- Disadvantaged Communities: At least 40% of direct climate investment benefits will target underserved and marginalized areas, supporting community solar projects, job training, and energy resilience upgrades.
- Public Health: Replacing fossil power with solar cuts air pollution, which can prevent hundreds of thousands of premature deaths over the next three decades.
- Rural Revitalization: Utility-scale solar installations provide new income streams for landowners, property taxes for counties, and economic diversification in agricultural regions.
This comprehensive focus on a just transition ensures that clean energy expansion doesn’t just fight climate change, but also advances economic inclusion and environmental justice.
