China is a clean energy powerhouse, although energy security concerns continue to fuel approvals of new coal-fired power plants. China accounted for 19% of global GDP in 2023 and its annual economic growth rate of 5.2% narrowly exceeded the government''s annual target. Despite initial signs that the recovery would be swift, China''s economy ...
Renewables are on track to set new records in 2021. Renewable electricity generation in 2021 is set to expand by more than 8% to reach 8 300 TWh, the fastest year-on-year growth since the 1970s. Solar PV and wind are set to contribute two-thirds of renewables growth. China alone should account for almost half of the global increase in renewable ...
So, it''s encouraging that innovators continue to pioneer fresh approaches that are making the goal of switching the world to renewable energy more achievable. Here are five such energy innovations. Solar and wind power working together. These turbine-solar panel units can be used on rooftops. Image: Unéole.

MENA countries are currently home to nearly 15% of the world''s installed energy storage capacity, but this total will need to grow to enable variable renewable energy systems to be integrated into the region''s power grids in a …
Our research shows considerable near-term potential for stationary energy storage. One reason for this is that costs are falling and could be $200 per kilowatt-hour in 2020, half today''s price, and $160 per kilowatt-hour or less in 2025. Another is that identifying the most economical projects and highest-potential customers for storage has ...
As the world transitions to decarbonized energy systems, emerging long-duration energy storage technologies will be critical for supporting the widescale …
For instance, Zhang et al. [5] tested the performance of a renewable energy system with on-site energy storage alternatives: hydrogen (P2H2P) or lithium battery, while Schöne et al. [6] proposed a P2H2P system for an off-grid community that typically uses
