I'm on FSD 13 and it takes the wrong route home thru an alleyway. I need to be able to alter the route so I can stay on the street. When is that happening?

Good morning with good news: South Korea now requires parking lots for 80 or more cars to install solar! 2-3 GW of solar results! cm.asiae.co.kr/en/article/2...

China's consumption of transport fuels (gasoline, diesel, kerosene) fell 4% in Jan-Sep.

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

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.

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.

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?

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

www.theguardian.com/environment/...

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. The fossil era is running out of daylight. ⚡🌍 #SolarDominion #Lithium #BESS #DisruptionDecade

Solar energy is going to power the world much sooner than you think

Solar electricity is growing rapidly, but can it really dominate the global energy system? Here is what it will take for us to power the planet on sunshine

‘Change course now’: humanity has missed 1.5C climate target, says UN head

Exclusive: ‘Devastating consequences’ now inevitable but emissions cuts still vital, says António Guterres in sole interview before Cop30 * I am the first Indigenous journalist to exclusively interview António Guterres. How many others will listen? Humanity has failed to limit global heating to 1.5C and must change course immediately, the secretary general of the UN has warned. In his only interview before next month’s Cop30 climate summit, António Guterres acknowledged it is now “inevitable” that humanity will overshoot the target in the Paris climate agreement, with “devastating consequences” for the world. This interview is also published in English, Portuguese and Spanish by Sumaúma. Continue reading...

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.
