Heat pumps are the most efficiency heating technology ever invented.
That's because they harvest, compress and transport pre-existing heat from the air, the ground or the water.
Compared to a gas boiler heat pumps deliver ~4x more heat for each unit of energy inout.

#India saw fossil generation FALL in the first half of 2025, as clean power grew rapidly ⚡️🇮🇳
Coal generation and emissions fell, even as India’s economy kept growing.
Can #COP30 keep this momentum going?

Over 2/3 of primary energy is wasted as heat.
The transition isn’t about matching that waste — it’s about outperforming it with efficient clean energy technology.

As the EU electrifies more end-use sectors, fossil demand will fall 3x faster than the rise in electricity use – cutting dependence on fossil imports.
Switching from fossil to electricity across energy end-uses boosts efficiency while decarbonising.

The EU still relies heavily on imported fossil fuels in most sectors.
This does not have to be the case – the EU power sector has relatively low fossil reliance – just 19%.
