- Good morning with good news: Wind & solar set two new global records in March 2025. 1. W&S generated 18.86% of world's electricity, a record high share! 2. W&S generation set a monthly record of 471 TWh in March 2025! That's up ~18% since March 2024 and ~145% since March 2019. #energysky
- Battery Pack Costs go down another ~40% by 2030. Global average battery back prices fall from ~$!15/kWh in 2024 to ~$65/kWh says Goldman Sachs. Low battery prices (plus solar) are existential threat to oil burning vehicles and fossil fuel burning power plants. Wonderful! #eenrgysky.
- Good morning with good news: Average price of lithium ion battery packs plunged to $115 USD/kWh in 2024, a 20% cost reduction from 2023. and down 84% from a decade ago. So, battery deployment skyrocketed 67%/year over the last decade to 69 GW in 2024. #energysky ember-energy.org/app/uploads/...
- Good morning with good news: Brazil's solar output surged 44% in March 2025, compared to March 2024! Solar was 13.29% of Brazil's electricity in March 2025 versus 9.66% in March 2024. Solar was at 0.47% in March 2018 & 1.7% in March 2020. Brazil ranked 4th (18.9 GW) in 2024 new solar. #energysky
- Below is Brazil's skyrocketing solar output in TWh. Brazil ranked 4th globally in new solar installations with 18.9 GW during 2024! It is forecasted to install 19.2 GW of new solar in 2025, so Brazil's solar output surge continues. Solar is more than Brazil's electricity demand growth. #energysky
- It took 70 years for the world to install 1 TW of solar by 2022. The world reached 2.2 TW of solar in 2024, taking ~2 years to install the second TW. The world installed 597 GW of solar in 2024. It is on track to install 1 TW/year by 2028-2030! #energysky api.solarpowereurope.org/uploads/Glob...
