Clean Energy Solutions Are Stepping Up to the Plate
Solar has made incredible leaps and is on course to be the largest source of generating capacity for electricity by mid-2035. To put it in perspective, back in 2004, it took an entire year for solar sources to produce a gigawatt of power. Now it takes just half a day. But electricity grids always need to be balanced between supply and demand—and while sunshine and wind are plentiful and free, they’re not available 24/7.
Companies need access to stable, consistent baseload power. To complement wind and power, they require a diverse range of decarbonization solutions to mitigate the intermittency challenges from traditional renewable sources and to decarbonize hard-to-abate areas of their business. These decarbonization solutions are at various stages of scaling, ranging from well-established technologies like wind, solar and large-scale nuclear to rapidly maturing options such as batteries and sustainable aviation fuel (SAF). And over the longer term, technologies like small modular reactors (SMRs), microreactors and hydrogen show a lot of promise.
But today, three technologies are making notable strides: nuclear, batteries and SAF.
Nuclear
Currently, nuclear is the only commercially viable provider of baseload carbon-free power. Over time, technological advances, shifting public sentiment, the need among governments for energy security and increasing corporate demand have resulted in a nuclear industry resurgence.
Indeed, several global technology players have recently announced plans to restart or enable the development of nuclear capacity. For example, Microsoft signed an agreement in 2024 to restart the Palisades reactor in Michigan, which had been decommissioned in 2022, to serve its data center footprint. And Meta announced that it is seeking up to 4 GW of new nuclear power to help meet its AI and sustainability objectives.6 Hyperscalers need reliable, low-cost, stable baseload solutions at scale—and they are increasingly looking to a small number of trusted partners to deliver what they need, where they need it and when they need it.
These tailwinds have resulted in life extensions for an increasing number of existing nuclear reactors as well as renewed interest from federal and local governments expanding nuclear power by building new plants. About 30 countries—ranging from sophisticated economies to developing nations—are considering, planning or starting nuclear power programs.
Looking ahead into the next decade, advances in SMRs and microreactors are opening up new possibilities for nuclear power applications—particularly for behind-the-meter and off-the-grid use by industrials, technology and mining companies, as well as remote communities. These innovative solutions are not only more flexible and scalable but also offer enhanced safety features. The development of long-duration energy storage systems further complements nuclear power, making it an even more attractive option for meeting future energy needs. While full-scale deployment is still several years out, we expect small-scale nuclear to form part of the long-term energy solution.
Batteries
Battery prices have dropped dramatically over the past few years, following a trajectory similar—but faster—than what we saw with solar. This was mainly due to improving technology, economies of scale, market dynamics and a fall in prices of critical battery metals like lithium, cobalt and nickel. For example, lithium carbonate prices fell from a high of approximately $70,000 per metric ton to well below $15,000 in 2024.7 Batteries now also require less time to plan and install than solar and wind systems (see Figure 4).
