Is National Grid plc (NGG) Among The Most Undervalued Renewable Energy Stocks To Buy?

We recently published a list of 10 Most Undervalued Renewable Energy Stocks To Buy Right Now. In this article, we are going to take a look at where National Grid plc (NYSE:NGG) stands against other most undervalued renewable energy stocks.

In 2024, global energy demand increased by 2.2%, quicker than the average over the last decade. Electricity use rose significantly, up 4.3% from last year, primarily due to hotter temperatures, electrification, and the growing digital sector. Renewables were the biggest contributors to the higher energy supply, followed by natural gas and coal. Most of the demand growth came from emerging economies, especially China and India. Natural gas had the strongest growth among fossil fuels, while oil demand softened, plunging below 30% of the energy mix for the first time in 50 years. According to the International Energy Agency, more than 80% of new electricity generation came from renewables and nuclear power in 2024. Solar and wind energy hit new records, and EV sales skyrocketed past 17 million units.

Solar capacity grew by 88% last year, helping it overtake hydropower and nuclear as the fourth largest source of installed capacity. While wind power faced hurdles like supply chain issues and permitting delays, it still set a new generation record and even outperformed coal for two straight months. Battery storage also saw impressive growth, rising by 64%, as utilities used it to store extra wind and solar energy. Looking ahead to 2025, Deloitte expects clean energy demand to grow even more, driven by the rise of clean tech manufacturing, data centers, and carbon capture projects, all of which are increasingly relying on 24/7 clean power.

The American nonprofit organization, Resources for the Future, noted that clean energy saw a major boost with a record $2 trillion invested in technologies like renewables and energy-efficient infrastructure during 2024. This sped up the global energy transition, especially in solar and wind power. While renewables are now some of the cheapest energy sources, fossil fuels, especially coal and gas, still make up a big part of global energy use. Coal is expected to decline significantly by 2050, while the role of gas depends on how ambitious climate policies become. Regions like the United States, Europe, and especially China have led solar growth, but other countries are starting to catch up. However, high costs and financial risks in developing countries could slow things down.
