The solar thermal energy supply in Belgium has experienced varied growth patterns from 2013 to 2023. Looking at 2023, the value stood at 306.73 Gigawatt hours. The period from 2013 to 2018 saw a strong upward trend, with substantial yearly increases and high compound annual growth rates (CAGR). However, from 2019 onwards, growth has significantly slowed, with occasional minor declines, and a markedly lower CAGR, particularly between 2022 and 2023 at just 0.14%. This indicates a leveling off in growth for solar thermal energy supply.
From 2023 onwards, forecast data suggests a steady but very gradual increase in supply, reaching 313.43 Gigawatt hours by 2028. The forecast 5-year CAGR is a modest 0.33%, indicating a stable but low growth environment. Over the entire period, solar thermal energy supply in Belgium displayed a clear tapering in growth rates.
Future trends to watch for include technological advancements in solar thermal energy that could spur renewed growth, and policy changes aimed at promoting renewable energy. Additionally, market demands driven by environmental goals and energy consumption patterns will play a crucial role in shaping the future outlook. Monitoring these factors will be critical to anticipating shifts in the solar thermal energy supply trajectory.
