We continue with our discussion of investment ideas that could benefit from upgrading and expanding the power grid to accommodate surging demand from AI data centers and EVs.
This third and final part of this series focuses on alternative energy sources, utility companies, and other companies related to the power grid infrastructure.
If you haven’t read Parts ONE or TWO we recommend reading them before continuing.
In 2022, the Department of Energy calculated that renewable energy from solar, wind, hydro, geothermal, and biomass accounted for a fifth of all electricity generation. By 2028, the IEA thinks the percentage will double to 42%. Solar and wind power are expected to be the primary alternative energy sources.
Investments in solar, wind, and other alternative energy sources, along with natural gas, coal, and nuclear, will be increasingly vital to power our utility plants. Furthermore, suppose the US and other nations continue to strive for net zero emissions by 2050 and other environmental goals. The demand for existing and new alternative energy sources will surge in that case.
Renewable energy has benefits and flaws compared to natural gas. The significant advantage of renewable energy is it produces minimal greenhouse gas emissions, as shown below. Second, and equally important, according to the IEA World Energy Outlook, solar and wind energy are the cheapest renewable energy sources and cost much less than carbon-based ones.
However, they have considerable flaws that need to be overcome. Consider the following from Green Solutions.
Relies heavily on weather conditions. When adverse weather conditions occur, renewable energy technologies like solar cells may not be as effective. For example, during periods of rain, PV panels cannot generate electricity, necessitating a shift back to traditional power sources.
Lower efficiency. Regrettably, renewable technologies generally exhibit lower efficiency compared to traditional energy conversion devices. For example, commercially available solar panels have an efficiency of about 15% to 20%. In contrast, traditional technologies utilizing coal or natural gas can achieve efficiency levels of up to 40% and 60%, respectively.
High upfront cost. The manufacturing and installation processes for renewable energy devices, such as PV panels, can be relatively expensive. Only for installation, solar panels cost about $17,430 to $23,870 on average.
Limited geographical region. The availability of high-quality land is limited, leading developers to urgently search for new sites. For example, in Germany, regulatory, environmental, and technical limitations significantly reduce the potentially suitable for onshore wind farms to just 2%.
Shortages of key raw materials. This includes essential metals like nickel, copper, and rare earth metals, such as neodymium and praseodymium, which are vital for the creation of magnets used in wind turbine generators.
We caution you that lithium deposits are being actively explored. Assuming success, the lithium supply may limit the price appreciation of lithium. As an example from The Hill- Researchers make massive lithium discovery in Pennsylvania.
Dominion Energy (D) in Virginia and Entergy (ETR) in Texas are the two utility companies that may be the biggest beneficiaries of the growth of AI data centers. Both stocks have relatively low forward P/E’s of approximately 14 and dividend yields of 4.25% for D and 5.50% for ETR. It will be crucial to follow their margins to see how effectively they offset the expansion costs with rising revenue.
Constellation Energy (CEG) and NextEra Energy (NEE) are also worth tracking as they invest heavily in renewable energy infrastructure and will benefit from increased demand. We would add Duke (DUK) and Southern Company (SO) to the list of companies to follow.
Renewable Stocks Are Not Following the Narrative
With time, we believe renewable energy will become much more efficient and hopefully be in a better position to help meet the surging needs of the nation’s utility plants. Investors do not seem as hopeful. The recent narrative pushing investors to power grid-related investments has skipped past renewable stocks. The graph below shows two popular alternative energy ETFs, Invesco’s Solar ETF (TAN) and iShares Global Clean Energy ETF (ICLN). Both ETFs are well off their 2008 highs and recent peaks in late 2020. Alternative energy stocks and diversified ETFs may be excellent investments for longer-term investors as renewable energy will be relied upon heavily. Furthermore, their stocks have not benefited from the power grid expansion narrative.Batteries Technology Is Vital To Renewable Energy
Solar and wind energy are not dependable due to weather conditions. For example, the following quote from OilPrice.com: But while solar power has made the U.S. power-generating system greener, it has also made it more volatile, especially in the top solar market, California. There, peak solar power generation coincides with the lowest residential electricity demand during the midday. When power demand begins to surge after 6 p.m., solar output begins to fade. In California, for example, “on sunny spring days when there is not as much demand, electricity prices go negative and solar generation must be ‘curtailed’ or essentially, thrown away,” says the Institute for Energy Research (IER). Accordingly, utilities need more efficient batteries to store excess renewable energy for use during peak demand periods and when the weather isn’t conducive for electricity generation. Without more efficient batteries, undependable alternative energy sources cannot be relied upon as much as the environmental goals demand. Companies involved in energy storage, especially those at the forefront of producing more efficient batteries, may have significant upside. But, with unproven technology come substantial risks for investors. For instance, many new types of battery technology are in development.- Solid-state batteries

- Cobalt-free lithium-ion batteries
- Sodium-ion batteries
- Iron-air batteries
