Renewable energy has become one of the most attractive sectors for investment in the modern world. The increasing focus on environmental pollution and climate change, coupled with rapid technological advancements in this field, make it highly promising for businesses and investors. In this article, we will examine the major global trends in renewable energy investment and the modern tools that facilitate the development of this sector. One of the key trends is the growth in investment volumes in renewable energy. According to the International Renewable Energy Agency (IRENA), investments in renewable energy surpassed $300 billion in 2023, marking a record high. This increase in investment is driven by both government support programs and private investors who see high potential profitability in this sector. Another important trend is the expansion of investment geography in renewable energy. While previously the main markets were in Europe and North America, there is now active development in markets across Asia, Africa, and Latin America. This is due to both the overall growth in energy demand in these regions and political and economic strategies aimed at reducing dependence on coal and gas fuels. Today, there are several modern tools that facilitate investment in renewable energy. One of them is green bonds. These are special bonds issued by companies or governments, the proceeds of which are used exclusively for the development of renewable energy projects. Green bonds are becoming increasingly popular among investors who seek not only financial returns but also to contribute to sustainable development. Another tool is socially responsible investment funds, which specialize in investing in enterprises and projects related to sustainable development, including renewable energy. These funds are guided not only by financial criteria but also by environmental and social criteria, making them attractive to investors who aim to have a positive impact on society and the environment.
