Clean Investment Monitor: US Q1 2026 Update
In the first quarter of 2026, clean energy and transportation investment in the United States totaled $61 billion, a 3% decline from Q4 2025 and a 9% decline from Q1 2025.
Energy & Climate
Rhodium Group’s Energy & Climate practice analyzes the effects of policy and market developments on greenhouse gas emissions and energy systems, and provides actionable information about the impacts of climate change. We help public and private decision-makers understand what kind of climate and energy future we are on track for, and what matters most for reducing greenhouse gas emissions—at the state, national, and international levels.

Worlds Apart: Contrasting US-China Approaches to Scaling Clean Technology Manufacturing
Global clean tech manufacturing investment has moderated after a decade of extraordinary growth. China and the US were the primary drivers of that rise and the subsequent pullback—though the nature of each country's decline differs significantly.

The Pathways report sets a target of achieving this level of deployment by 2030, whereas our analysis extends through 2035. This validation suite can still play a critical role in enabling geothermal’s liftoff over a longer timeline.

When discussing private and federal investment, we refer exclusively to capital expenditures (e.g., buildings, equipment) and not ongoing operations and maintenance (O&M) spending. We incorporate both capital and O&M expenditures when calculating employment impacts below. Private and federal investment reflects total investment net of state government expenditures, which we unpack in further detail below.

These ratios reflect our high geothermal manufacturing scenario. In our low geothermal manufacturing scenario, $1 of state investment yields $3.36 and $3.35 of private and federal investment in the State Action and Enhanced State Action scenarios, respectively.

We assume a representative 20 MW turbine for analytical purposes; however, recent announcements indicate that even larger turbines may be feasible. Turbine cost and size assumptions flow through to the economic impact analysis. Larger turbine sizes may slightly reduce total investment, jobs, and tax revenues due to economies of scale.
