The underlying fundamental economics have changed dramatically: solar is now so cheap that businesses and households all around the world install it often without subsidies. Throw in batteries and the business case just keeps improving.

One of the world’s largest industrial heat pumps is coming to Boston.

A 35MW system will use energy from the Charles River and deliver steam to heat more than 70 million square feet of buildings across Boston and Cambridge — hospitals, schools, homes, and businesses alike.

Good morning with good news: New solar plus storage in India is more than 25% cheaper than EXISTING coal plants. It's also much cheaper than new coal plants!

Indian solar plus storage costs $33–41/MWh
EXISTING coal costs $54/MWh
New coal costs $67-83/MWh

Busting a Myth:
Clean, Renewables Lower Electricity Prices

11 US states met 51-120% of their electricity demand for the year between mid 2024-2025 with just clean, renewable sources. Of these, 10 had electricity prices at least 2 c/kWh below the US avg

Trump got schooled. He had no leverage to negotiate. When China starts making their own chips in a year or two, we will have nothing to offer. Sad to see our country led by a conman who knows nothing about foreign policy

NEW | Offshore wind is still on track to TRIPLE globally by 2030, despite uncertainty in the US.

27 countries, 27 sub-national governments and 3 regions now have targets in place, strong enough to sustain global growth.

US rooftop solar costs 7 times more than in Australia and 2.8 times more than in Germany.

Why?

Soft cost like permitting, inspections and interconnection are 78% of US rooftop solar costs.

Monopoly utilities and municipalities mainly drive these costs.

There is so much rooftop solar in South Australia that at times it supplies the whole state's needs. It's time the U.S. cut red tape so distributed energy can proliferate.

Thanks @mzjacobson.bsky.social for the inspiration for today's column. #greensky 🔌💡 #solar

Despite Washington’s reluctance, I can’t see the US resisting free markets forever. 🇺🇸⚡Texas, California, and half the states are already riding the solar + storage boom. The energy transition isn’t waiting for permission — it’s happening from the grid up. ☀️🔋 #Solar #BESS #EnergyTransition #Lithium
The global boom in solar — with or without the US
Despite the scepticism about renewables in Washington, falling prices for new panels are making a compelling business case around the world

Renewables are now cheaper than new coal power in India 🇮🇳

New coal: ~USD 68/MWh
Solar + storage: USD 33–41/MWh
Firm and dispatchable RE: USD 49–67/MWh

As renewables scale, India can meet its 2032 power needs without adding new coal.

Good morning with good news: US solar surged 28.8% in Jan-Aug 2025, compared to Jan-Aug 2024!

Solar & wind produced 19.1% of US electricity in Jan-Aug 2025, up from 17.2% in 2024!

All RE generated 26.1%, up from 24.5%.

Battery storage grew by 63.9%!

US fossil fuel generation continues to lose market share in 2025.

Fossil fuels fell to ~50% for a couple months in 2025.

After recently being more than 60% of US electricity, fossil fuels will fall to ~55% for all of 2025.

Why?

Surging solar and wind generation! #energysky

NOAA’s hurricane research division staff has been cut from 52 in 2020 to 28 in 2025, almost a 50% cut. They’ve resorted to using volunteers to man the critical radar and dropsonde stations on Hurricane Hunter flights. Senseless cuts in an era of climate change making the strongest storms stronger.

Interesting study from researchers at UCL on how wind power has held down energy costs in the long term.

The key argument is that it has lowered gas prices in Europe by reducing demand for gas. And actually most of the savings are on gas, not electricity bills

Wind power has cut £104bn from UK energy costs since 2010, study finds
Reduction comes from energy generated from windfarms and lower cost of gas owing to lower demand

Solar isn’t coming — it’s here, scaling faster than anyone modelled. ☀️ The serial underestimators, the IEA, now say solar beats nuclear ’26, hydro ’29, gas ’31, coal ’32 — and could power everything by ’35.

Last new coal plant proposals cancelled or shelved in Thailand, Kenya, Tajikistan & Uzbekistan, Cambodia deciding not to build any new coal, Morocco committing to a 2040 coal phase-out, proposals for new coal power outside China at record low - lots of progress happening outside front page news.
New data from our Global #CoalPlant Tracker is out. A few key trends:

📉 Countries w/coal power under dev't hit a record low — only 33 remain since the Paris Agreement.
📉 New proposals fell below 2 GW in Q3 2025 — 85% below recent averages.

Good morning with good news: Why did global EV sales skyrocket 26% in 2025 for Jan-Sept, reaching 2.1 million sales in September?

LEAF 2011 versus Leaf 2026 shows why: HUGE EV improvement with a 33% price drop.

EV innovation also is just starting!

Saudi Arabia signed deals to build another 5 GW of renewables (3 GW of wind and 2 GW of solar) that will operate in 30 months!

Saudi Arabia will have 12.7 GW of RE operating by end of 2025 & 20 GW by 2026.

So, why is this Petrostate building RE?

ICE is finished in China.

Sales of petrol & diesel cars peaked in 2017 — the same year EVs started their takeoff. In 2020, only 1 in 18 new cars was electric. By 2024, it’s 1 in 2. This year it’s tracking for 60%.

This isn’t a fad — it’s the world’s biggest industrial shift in motion. #EV #Lithium
