The surge in global venture capital investment towards clean energy reflects a shift towards sustainable and profitable ventures amid climate change concerns. Investments in renewable energy surpassed $300 billion in 2020, indicating a rising demand for greener alternatives. Clean energy innovations in solar, wind, and energy storage technologies are attracting not only traditional venture capitalists but also tech giants and institutional investors. Government support through policies and incentives further accelerates the transition to cleaner energy sources. However, controversies arise regarding the environmental impact of clean energy technologies, especially in the production and disposal processes. Critics raise concerns about the neglect of emerging technologies like hydrogen in favor of well-established options like solar and wind. The involvement of tech giants in clean energy presents both opportunities and challenges, with issues surrounding market competition and innovation. Despite supportive policies in various countries, the lack of international regulatory alignment poses obstacles for seamless clean energy investments and projects. As the clean energy sector continues to evolve, navigating the investment landscape requires a balance between financial opportunities, environmental considerations, and technological advancements.
