Amid a disrupted market landscape and lower carbon expectations, the global energy sector is hurrying to adapt to the evolving market conditions. Some of the best alternative energy stocks to buy in the oil and gas sector have been ramping up investments in the renewable energy business, clean energy players are expanding operational capabilities, and a greater number of sustainability-focused entrepreneurial ventures are springing up to capitalize upon the fast transition to renewable energy and to deliver innovative solutions to the transforming market. According to McKinsey's Global Energy Perspective 2022, despite being significantly well-positioned to cash in on the energy transition, oil and gas companies are expected to continue their reliance on fossil fuels as a substantial part of the global energy mix, at least till 2050. Some of the reasons for this is the increased affordability and security of supply which is indicative of fossil fuels in the 21st century. However, the report postulates that these companies are also likely to continue investments in clean energy due to their sheer global scale, the magnanimous capacity for risk of their investors, their substantial income statements and balance sheets, and their favorable equations with energy consumers and shareholders. Some of the most prominent players leading the clean energy transition are NextEra Energy Inc. (NYSE:NEE), General Electric Co. (NYSE:GE), and Tesla Inc. (NASDAQ:TSLA).

However, according to Bloomberg, the power sector, which includes some of best alternative energy stocks to buy, needs to make a more concerted effort in its transition towards alternative energy models by 2050. The International Energy Agency updated that the energy sector is still the world's largest emitter of atmospheric carbon. And although solar power and EV sales have boomed since the IEA's 2021 update, the current projected limit to global warming of 2.4C is still too much. This is coupled with the fact that carbon emissions by the energy sector set a new total high of more than 40 billion tons in 2022 owing to the post-COVID economic rebound and the global energy crisis which was exacerbated by Russia's 2022 invasion of Ukraine. This led to a widescale competition to produce and burn a greater number of fossil fuels, especially in China, India and other developing countries around the world. Wind power is also struggling due to skyrocketing inflation rates and political pushbacks, the latter causing numerous large-scale wind projects to be stalled indefinitely.

In a 2023 report, McKinsey and Company outlined certain key areas which can generate substantial value for energy companies amid the energy transition, one of them being offshore project development. Oil and gas companies can invest in integrated projects, including clean energy generation and hydrogen and heat production. Furthermore, players like NextEra Energy Inc. (NYSE:NEE), General Electric Co. (NYSE:GE), and Tesla Inc. (NASDAQ:TSLA) have histories with hydrogen production in their refining and chemical processes. Since existing capacities are integral for clean hydrogen production and transportation, the best alternative energy stocks can build on their capabilities to increase clean energy generation. Thirdly, clean energy companies may also leverage their brands, consumer relations, real estate, and fuel stations near freeways to deliver fast-charging EV solutions to customers. Lastly, increasing public scrutiny has pressured oil and gas players to decarbonize through increased investments in technical solutions and expertise. These added capabilities can be used to improve upon decarbonization services like clean energy generation, renewables retail, batteries and CCUS (carbon capture, utilization, and storage). Since the industry is still heavily reliant on fossil fuels and fosters favorable relationships with suppliers, its  representatives deserve a seat at the table when developing the transition strategy.
