Looking at the Data
Renewable Energy Growth
Solar energy continues to be a significant driver of global energy transitions, with substantial growth projected for the next few years. In 2024, the global market for solar power is expected to expand rapidly, with the United States recording a 48% growth rate in solar PV installations, adding 32.4 GW of new capacity. This growth is part of a broader trend where solar PV is set to meet half of the increase in global electricity demand in 2024 and 2025.
The International Energy Agency (IEA) forecasts that solar PV will account for 4.5% of total global electricity generation by 2050, with over half of this capacity expected to be deployed in China and India. This growth is supported by declining prices of solar panels, which have made solar PV installations more affordable and accessible to a broader range of consumers. The IEA also projects that renewable sources, including solar PV, will meet 35% of global electricity supply by 2025, surpassing coal for the first time.
In the United States, the solar industry has continued to lead the energy transition, representing 75% of new capacity in the first quarter of 2024. The Inflation Reduction Act (IRA) has significantly boosted the solar outlook by providing long-term tax credits and manufacturing provisions, which have made the market more certain and attractive for investors. The IRA is also expected to drive growth in emerging commercial markets and community solar programs, expanding access to solar energy for various households and businesses.
Hydropower, another renewable energy source, has seen a recovery in China, with hydropower production recovering strongly in the first half of 2024. This recovery could curb coal-fired power generation and result in a slight decline in global power sector emissions in 2024. Despite this recovery, hydropower's share in the global energy mix remains relatively stable compared to other renewable sources.
Biomass energy, which includes the use of organic matter such as wood, agricultural waste, and municipal waste, is another renewable energy source with significant potential. Biomass energy can be used for power generation, heat production, and biofuels. However, its adoption is often limited by environmental concerns and competition with other renewable sources.
Geothermal energy, which harnesses the heat from the Earth's core, is another renewable energy source with a growing role. Geothermal energy is often used for electricity generation and heating applications. While it has a smaller market share compared to solar and wind, geothermal energy is a reliable and sustainable source of power, especially in areas with high geothermal activity.
In summary, solar energy is expected to continue its rapid growth, driven by declining prices and increasing adoption. Hydropower has seen a recovery in China, but its overall share in the global energy mix remains stable. Biomass energy and geothermal energy are also significant renewable sources, though their adoption is often limited by environmental concerns and competition with other renewable sources. The global energy landscape is shifting towards a more sustainable and renewable future, with solar energy playing a central role in this transition.
