The global solar power generation has outstripped wind energy production since May this year, marking a historic shift in the renewable energy sector. According to data from the energy think tank Ember, solar electricity generation exceeded that of wind by 1.65 terawatt hours (TWh) in May and by an even more significant margin of 9.57 TWh in June.
While global data for July is pending, it is anticipated that solar power will continue to lead, given that July typically represents the peak period for solar output in the northern hemisphere. The trend is expected to persist into August, as the month is generally characterised by high solar generation and lower global wind speeds, which typically result in reduced wind energy production. Prior to this, solar power had only temporarily surpassed wind generation in June and August of 2023. This extended period of solar dominance highlights a significant shift in renewable energy dynamics, as solar farms have managed to maintain higher generation levels over several consecutive months.
Looking forward, it is anticipated that wind power will reclaim its leading position in the global renewable energy landscape as the solar output declines with the changing angle of the sun’s rays. The onset of winter in Europe, North America, and Northern Asia is expected to enhance wind speeds, thereby boosting wind power generation. For the full year of 2024, projections indicate that wind-generated electricity will outstrip solar power by at least 30 per cent, as winter months are historically more favourable for wind energy production. This anticipated shift underscores the seasonal variability inherent in renewable energy sources and highlights the ongoing need for a diversified energy mix.
