Key Trends in Renewable Energy for 2023 and Beyond

​As the world continues to grapple with the challenges posed by climate change, the renewable energy sector stands at the forefront of innovative solutions. Our experts noted in our 2023 Global Energy Salary Survey that 2022 will surely go down as a key catalyst in the drive towards the international phasing out of fossil fuels. From emerging technologies to decentralised energy systems and green finance, let's explore the key trends that will define the renewable energy sector in 2023 and beyond.

Emerging Technologies in Renewable Energy

The relentless pursuit of efficiency and sustainability has propelled the development of groundbreaking technologies in renewable energy. Throughout 2023 and looking to the year ahead, the following innovations have taken centre stage and will continue to do so:

• Next-Generation Solar Panels: Traditional photovoltaic cells are being eclipsed by advanced solar technologies, such as perovskite solar cells and bifacial panels. The National Renewable Energy Labratory reports that these technologies promise increased efficiency, lower manufacturing costs, and the ability to generate power from multiple angles, making solar energy even more accessible and versatile.
• Energy Storage Breakthroughs: Energy storage is a critical component of renewable energy adoption, enabling the management of intermittent sources like solar and wind. 2023 has seen advancements in battery technologies, including solid-state batteries, which Financial Times reports are expected to continue to grow by 2030 as they offer higher energy density, faster charging, and enhanced safety.
• Hydrogen Economy Expansion: Green hydrogen continues to gain traction as a clean energy carrier. Electrolysers powered by renewable sources are being used to produce hydrogen, which can be used for various applications, including fuel cells for transportation and industrial processes. IEA reports on electrolysers' role in clean energy and where we go from here.

Transitioning to Decentralised Energy Systems

The energy landscape is undergoing a significant transformation as the world shifts from centralised power generation to decentralised systems. This transition holds great promise for increasing energy access, reducing transmission losses, and enhancing grid resilience:

• Microgrids and Localised Generation: Communities and businesses are embracing microgrids, small-scale energy systems that can operate independently or in conjunction with the main grid. These systems are particularly valuable in remote areas or during grid outages, ensuring a consistent power supply.
• Peer-to-Peer Energy Trading: Blockchain technology is facilitating peer-to-peer energy trading, allowing consumers to buy and sell excess renewable energy directly with their neighbours. This decentralised approach empowers individuals and communities to actively participate in the energy market.

Green Finance and Investment in Renewable Energy

Green finance has emerged as a powerful driver in the renewable energy sector, offering not only sustainability benefits but also attractive investment opportunities. So far, in 2023, the financial landscape has witnessed a remarkable transformation as it aligns more closely with the principles of environmental responsibility.

The issuance of green bonds has gained significant momentum. These bonds are designed to fund environmentally friendly projects, including large-scale renewable energy initiatives that will be rolled out in various parts of the world over the next decade. Investors are increasingly drawn to green bonds because they not only provide financial returns but also contribute to a greener future. Additionally, the establishment of sustainable investment funds allows individuals and institutions to invest in portfolios dedicated to clean technologies, further accelerating the transition to renewable energy.

Moreover, Environmental, social, and governance (ESG) criteria are becoming integral to investment decisions. Companies and projects involved in renewable energy often score exceptionally well in these areas due to their positive impact on the environment, their commitment to social responsibility, and their just governance practices. As investors increasingly prioritise ESG considerations, renewable energy investments are poised to attract substantial capital. This shift underscores the broader recognition that sustainable investments can be both ethically sound and financially rewarding.
