MySustainableCorner – May 2026

This month in a nutshell

• Renewable energies now account for one-third of global electricity generation, surpassing fossil fuels for the first time. This shift is driven by solar power, particularly in Asia. However, the diurnal nature of solar presents challenges, sometimes leading to negative prices and curtailment (voluntarily reducing the output of a power plant) during periods of abundance. To address this, the global deployment of storage batteries is massively accelerating, with an addition of 247 GWh in 2026.
• In February 2026, the City of Paris issued a new sustainable bond sized €350 M, with the aim of financing the development of clean transport (metro lines, cycle paths), the energy renovation of social housing, and adaptation to climate change through the greening of public spaces.
• The European Union and its partners have launched a fund aimed at financing sustainable infrastructure through green bonds, capable of mobilising up to €20 bn. The objective is to attract private investment to accelerate the climate transition in developing countries. This initiative also aims to strengthen Europe's role as a leader in green finance.
• L'Autorité des Marchés Financiers (French regulatory authority AMF) is launching a 2026-2028 plan to bridge the gap between men and women in investment. In 2025, only 24% of women invested in the stock market, a gap explained less by income than by a lack of confidence or a feeling of illegitimacy. The "Women and Investment" initiative will study these barriers starting in 2026 to build a dedicated financial education strategy from 2027.

Change in electricity generation in 2025 vs. 2024 (TWh)

In 2025, the global increase in electricity demand was entirely met by low-carbon sources. Solar power drove most of this growth, ahead of wind and nuclear. Global fossil fuel electricity generation saw a slight decline.
