You're right to highlight the importance of ongoing technology improvements in driving renewable energy growth. Some of the key advancements outlined in the report include:

- Higher efficiency solar panels through new materials like perovskites, bifacial designs that capture light from both sides, and panel manufacturing advances. Field testing of solar shingles and fabrics as well.

- Larger wind turbine blades reaching 200 meters today compared to 30 meters in 1980s. Blade designs optimize aerodynamics to capture wind in complex terrain too. Condition monitoring reduces downtime.

- Floating foundations allowing wind farms to be located further offshore where winds are stronger and more consistent. This significantly expands suitable wind resource areas.

- Innovations in concentrated solar power (CSP) systems through thermal energy storage to provide renewable power after sunset and next-day grid balancing services.

- Advances in solar trackers for both PV and CSP that optimize energy yields by precisely aligning panels/mirrors towards the sun throughout the day.

- Improved renewable project design, energy management systems, and grid services like ancillary frequency/voltage regulation using batteries and intelligent inverters.

- Digitalization enables remote monitoring of renewable asset performance, predictive maintenance using IoT/AI, and decentralized renewable microgrids for remote communities.

The report forecasts these technology gains will boost renewable competitiveness versus incumbent fuels and facilitate greater penetration worldwide in the 2020s. Exciting growth ahead!
