5 No-Brainer Energy Stocks to Buy With $100 Right Now
Energy stocks have seen dramatic shifts in 2025, driven by rising electricity demands and new technologies. Companies from nuclear startups to established infrastructure giants are attracting investor attention. Some have posted record profits, while others remain speculative bets with no revenue yet in sight.
Oklo, a nuclear startup backed by Sam Altman, has become one of the year’s most volatile stocks. Its shares surged past $190 at their peak, marking a 787% gain for 2025. Despite the hype, the company remains pre-commercial, with no operating reactor or revenue. Altman, an early investor and former chairman, stepped down during talks to supply energy to OpenAI, a company he co-founded.
Meanwhile, Cameco’s stock has climbed steadily over the past year. The uranium producer benefits from a global push for nuclear power, fuelled partly by the energy needs of AI data centres. As one of the world’s largest miners of high-grade uranium, it operates with relatively low production costs. Bloom Energy has also delivered strong results, reporting record revenue and improved profit margins in recent quarters. The company, which makes solid oxide fuel cells converting natural gas into electricity, turned profitable in 2025. Major clients like FedEx and Walmart use its technology for cleaner energy solutions. Enbridge, a key player in North American energy infrastructure, continues its reliable performance. The company transports about 30% of the continent’s crude oil and operates the world’s longest oil pipeline. It has also maintained a 31-year streak of dividend increases, now paying CA$0.97 per share quarterly. Vistra, one of the largest competitive power generators in the U.S., serves around 5 million customers across 20 states. Unlike regulated utilities, it profits from market spikes and higher electricity demand, positioning it well as consumption grows.
The energy sector’s performance in 2025 highlights a mix of high-risk bets and steady earners. Oklo’s stock surge contrasts with its lack of revenue, while Cameco and Bloom Energy capitalise on rising demand. Enbridge and Vistra, meanwhile, maintain strong positions through infrastructure and competitive power generation. Investors now face a choice between speculative growth and established reliability.
