3 Alternative Energy Stocks to Watch Amid Escalated Tariff Uncertainty

The U.S. alternative energy sector faces both tailwinds and headwinds, with a forecasted 4.5% increase in wind generation for 2025 and a booming EV market offset by rising raw material costs and recently enhanced import tariffs that could constrain growth; despite these challenges, the industry has outperformed both the broader energy sector and the S&P 500 over the past year, surging 41.9%. Ormat Technologies, Standard Lithium, and Bloom Energy are highlighted as key players, with Ormat securing a $62 million tax equity partnership and Standard Lithium receiving a key royalty approval for its lithium project.

Analysis

The U.S. alternative energy sector presents a complex investment landscape, characterized by robust demand drivers juxtaposed with significant policy and cost pressures. The burgeoning electric vehicle market, evidenced by a 15% year-over-year sales increase in Q4 2024 and a projected 12.6% compound annual growth rate through 2029, alongside a U.S. Energy Information Administration forecast for a 4.5% year-over-year increase in U.S. wind generation in 2025 (with 7.7 GW of new capacity expected), underpins strong secular growth. Global clean energy investment also reached a record $2.08 trillion in 2024. However, recently enhanced import tariffs, notably a 25% levy on steel and aluminum imposed in March 2025, and a January 2025 executive order pausing offshore wind leasing, have exacerbated existing high raw material costs, contributing to $8 billion in cancelled clean energy projects in Q1 2025. Despite these headwinds and a Zacks Industry Rank placing it in the bottom 42% due to a negative near-term earnings outlook (current fiscal year estimates revised down 0.9% since March 31), the industry's stocks have collectively surged 41.9% over the past year. This performance has pushed the industry's current valuation to an EV/EBITDA ratio of 21.48, substantially above the S&P 500’s 16.65 and its own 5-year median of 10.43X. Specific company developments offer selective optimism: Ormat Technologies (ORA) secured a $62 million tax equity partnership to monetize $160 million in tax benefits in 2025, Standard Lithium (SLI) achieved a key state approval for a 2.5% lithium royalty rate, and Bloom Energy (BE) reported a 38.6% year-over-year revenue increase in Q1 2025.

Key Decisions for Investors

• Investors should carefully weigh the sector's compelling long-term growth drivers, such as EV market expansion and increasing wind generation, against significant near-term headwinds including heightened import tariffs, raw material cost inflation, and policy uncertainties.
• Close monitoring of evolving U.S. trade policies, particularly concerning tariffs on essential materials like steel and aluminum, and regulatory decisions affecting offshore wind development, is crucial as these factors will directly impact project viability and sector profitability.
• A selective investment approach is advisable, focusing on companies with strong fundamentals, demonstrable positive catalysts, and potentially favorable Zacks Ranks such as Ormat Technologies and Standard Lithium, while exercising caution due to the industry's overall elevated valuation multiples and the negative aggregate earnings outlook indicated by its Zacks Industry Rank.
