In this article, we will look at the 11 Best Alternative Energy Stocks to Buy Now.
The global energy market is going through a massive change as alternative energy sources are becoming increasingly popular and the world transitions away from fossil fuels. Governments, corporations, and investors are now prioritizing renewable energy sources. This is powered by favorable policies, technological advancements, and the rising demand for energy due to emerging industries like AI-driven data centers. Thus, energy stocks are becoming an attractive investment opportunity as the world moves toward sustainable energy alternatives.
Accordingly, global clean energy deployment hit a new record in 2023, driven by a growth of 85% in solar PV and 60% in wind capacity, as per the International Energy Agency (IEA). Investment in solar exceeded all other energy sources, breaching the $500 billion mark, as per the World Economic Forum. On the other hand, investments in battery storage surpassed $50 billion, adding to the strength of the energy storage solutions. Thus, these investments point toward the increasing demand for renewables in the global energy mix.
The acceleration of this transition has been majorly supported by federal policies. Initiatives worldwide, like the Inflation Reduction Act (IRA) in the U.S., have fostered the expansion of clean energy by presenting tax credits and incentives for renewable energy projects. Utility-scale solar and wind additions made up 90% of the total new capacity additions, up from 57% in 2023, according to a report by Deloitte.
The demand for electricity is also increasing as the expansion of AI, data centers, and cleantech manufacturing flourishes. According to Deloitte’s 2025 Energy Outlook, data centers could drive 44 GW of additional demand by 2030, adding to renewable energy solutions’ needs. Consequently, investments in solar, wind, and battery storage are expected to grow at an increasing rate.
On the other hand, nuclear energy is facing renewed interest. Although additions to nuclear capacity faced a decline in 2023, now the number of reactors globally under construction is at 58, emanating a total capacity of over 60 GW. Investments in the nuclear sector are doubled by countries like the U.S. and France, recognizing it as a potential reliable emissions-free energy solution.
Furthermore, the clean energy sector is propelled forward by increasing technological advancements and cost-cutting. The price of lithium-ion batteries has reduced by over 90% in the past decade, with a 40% decrease in 2024 alone, as reported by the World Economic Forum. AI also plays an important role in the optimization of energy storage, enhancing grid efficiency, and furthering renewable deployment.
Green hydrogen has emerged as a promising long-term solution. The capacity for hydrogen electrolyzers grew by 360% in 2023, largely due to China and the U.S. Such growth and advancements in hydrogen storage and distribution could potentially make hydrogen a viable alternative for industries requiring high-energy-density fuels.
Therefore, alternative energy stocks seem to be an attractive investment in light of strong policies, technological advancements, and increasing demand for clean energy. The Inflation Reduction Act in the U.S., as well as policies in Europe and Asia, have introduced incentives to encourage companies to expand their renewable energy initiatives.
Thus, the sector is positioned to be attractive for investors in terms of long-term growth due to its swift expansion, decreasing costs, and increasing adoption by the corporate sector. With this, let’s now look into the 11 best alternative energy stocks to buy in 2025.
