An analysis from @transitionzero.org shows that, for Pakistan, investing US$500m in batteries and renewables could save up to US$2.87b in RLNG costs and avoid #emissions spikes tied to global fuel shocks. Read more: www.transitionzero.org/insights/bat...

108,346 solar facilities. 1,331 GW detected globally. Capacity up 6.8% in one quarter. Spain leads Europe at 46 GW, and its solar-heavy grid is proving far more resilient to the Iran crisis than fossil-dependent neighbours. Q1 2026 data is live: www.transitionzero.org/insights/spa...

28 Apr

The Philippines could incur US$90.5bn in fossil system costs through 2040. 81% of that is fuel and variable costs. New modelling shows solar grows eightfold and 12 GW of battery gets built. But contract lock-in keeps coal and gas running. 🔗 bit.ly/4e8ITJ9

Grids will do the heavy lifting in the energy transition. They enable renewables, reduce costs, and create clean power trade routes. ⚡ But expansion is complex. How much? Where? What are the trade-offs? We explored these questions: www.transitionzero.org/insights/cab...

It's #EarthDay2026. Progress happens when people show up. For energy modelling, that means showing up with evidence.🌍 But modelling software is expensive. This is one reason we built Scenario Builder: a free, no-code energy system modelling platform. ➡️ bit.ly/46C5iKi

Coal outages in the Philippines surged 200% in 2025. ⚠️ The worst performers are the most contracted. When these plants go offline, supply tightens, potentially pushing up consumer prices through higher-cost alternatives. 📊 New TZ-CAT analysis: bit.ly/4svoq4E

Pakistan’s evening peak in 2026 reveals just how fragile a fossil fuel–dependent grid really is. New modelling by Renewables First using TransitionZero’s Scenario Builder shows what happens when fuel prices spike. 📊 Full analysis: www.transitionzero.org/insights/bat...

1 Apr

The Philippines signed 75 emergency coal contracts since 2022. Some cost 32 to 68% more than long-term deals. Without firm alternatives, supply gaps get filled with expensive short-term coal. New TZ-CAT analysis: www.transitionzero.org/insights/phi...

Japan can reach 50% renewable electricity with very little clean energy going to waste. But going further — towards a fully clean power system — will require something more: flexibility. 🔗 Read the full blog: www.transitionzero.org/insights/jap... @clientearth.bsky.social

⚡ Cutting coal doesn’t always mean more renewables. In Peninsular Malaysia, coal reductions could mostly shift to gas instead — up to 69–90% in our analysis. But Sarawak shows a cleaner pathway, where coal cuts could be replaced by hydropower. www.transitionzero.org/insights/coa...

🇵🇭 Could the Philippines exceed its renewable energy targets? Our modelling suggests renewables could reach ~54% of electricity generation by 2040, surpassing the 50% policy target, with solar driving most of the growth. Read more: www.transitionzero.org/insights/the...

Bangladesh’s rooftop solar push is gaining momentum, but progress remains modest. 🛰 Our satellite analysis estimates ~370 MWp installed as of Jan 2026, far below the 3,000 MWp target. 🔗 Full analysis → bit.ly/4ub1aLp

🔄 Most energy models don’t talk to each other. Long-term planning ≠ hourly dispatch. Built in isolation, they don’t align. We built an interoperable data model linking TZ-OSeMOSYS and PyPSA — one common language for capacity expansion and dispatch. Read more: bit.ly/4rMhuAJ

Malaysia’s data centres now use 3% of Peninsular electricity — triple the year before. Coal retirements after 2029 create a turning point. If clean energy and imports don’t scale fast enough, gas fills the gap, but will stay on for decades. Read more 👇 www.transitionzero.org/insights/mal...

🏭 Can coal plants in Southeast Asia run more flexibly? Technically, sometimes. Commercially? Much harder. Long-term PPAs, two-part tariffs & must-run clauses lock coal into baseload — even as solar and wind grow. Part II of our coal flexibility series explores why 👇 🔗 bit.ly/4aAHLut

🛰️ Indonesia's rooftop solar puzzle: plenty of sunshine, but minimal scale. Our satellite analysis found ~600 MWp installed - well short of the national target. The catch? 87% is concentrated in Java. The rest of the archipelago? Essentially zero. 🔗 Find out more: bit.ly/40eEoV2

🇲🇾 The Malaysian government has long viewed rooftop solar as a key lever for system decarbonisation, yet uptake has consistently fallen short of expectations, with low adoption reflected in official statistics. 👁️ We wanted to get a clearer picture of real, installed rooftop solar capacity...

11 Dec 2025

We found 1.75 GW of installed rooftop solar capacity nationwide, with 80% concentration in the industrial states of Selangor, Johor, Kedah, and Palau Pinang. Why is this helpful?
