Emma and Francesco ditched the plan, cracked open a few drinks, and chatted about everything climate.

Sparkling conversation tackling China’s new rule forcing data centres, steel, cement and polysilicon plants to source up to 80% of their power from clean energy; weighed in on geothermal potential, the looming water crisis and the need for greener housing; dug into why investor confidence and PR hiccups still hold back many clean-tech ventures—should biochar be pink?—and even circled back to the cool stuff they’ve covered before: Naked Energy, Samudra Oceans and Carbogenics.

Cheers!

What we cover:

• China is mandating significant green energy purchases from key industries, including steel and data centers.
• Geothermal energy is gaining attention as a sustainable energy source with global potential.

• Housing developments are slowly integrating solar technology, but challenges remain.
• The UK faces a water crisis that impacts infrastructure and energy management.
