Germany accused of ditching climate targets as it scraps renewables mandate Coalition government agrees to remove parts of controversial law and allow homes to rely on fossil fuels

5/5 (…contd.)

…and Germany dumps its low-carbon domestic heating requirements:

 ❝ While the previous law required most newly installed heating systems to use at least 65% renewable energy, often with a heat pump, the amended legislation will allow households to keep using oil and gas.❞

A chart showing the electricity generation from fossil fuels for the largest six EU nations from 2010 to 2025.

Germany and Italy have the largest electricity generation from fossil fuels.

For these six countries in 2025, electricity generation from fossil fuels was:

Germany: 205 TWh
Italy: 136 TWh
Poland: 119 TWh
Spain: 73 TWh
Netherlands: 62 TWh
France: 30 TWh

Italy wants to suspend the the EU carbon market.

Carbon pricing of gas is emerging as a politically contentious issue in the EU.

Italy has an exceptionally high gas share in its electricity mix.

🇮🇹 Last week, the Italian government announced their intent to reimburse the carbon cost paid by gas-fired power plants.

The motivation is clear - Italy has the largest gas share in power production across Europe.

The risk is that this prolongs that dependence and reduces renewables investment.

Progress in reducing emissions in Scotland – 2025 report to Parliament
Climate Change Committee

Electricity supply (excluding energy from waste):

electricity generation in Scotland is almost completely decarbonised. Electricity supply emissions were 0.7 MtCO2e in 2023, 0.6 MtCO2e lower than in 2021. Emissions are now 95% lower than 1990 levels.

Emissions fell rapidly between 2010 and 2017 as coal was phased out of the generation mix and largely replaced with wind and solar (Figure 2.5). The last remaining coal-fired power station in Scotland, Longannet, closed in 2016, leaving unabated gas generation, which also declined significantly in this period, as the main source of emissions.

Between 2017 and 2023, emissions reduced at a slower rate as continued deployment of wind and solar largely displaced retiring nuclear capacity. During this period, the share of generation from unabated gas remained around 10% up to 2022, until a fall to 7% in 2023. Remaining emissions are dominated by Peterhead power station, which in 2023 accounted for more than 90% of electricity supply emissions

Britain’s spark gap over the last 35 years has remained well above the level in other countries. Electricity for households is now 4.7 times more expensive than gas, giving Britain the highest spark gap out of the 25 major countries compared which provide retail price data. In contrast, the spark gap in France, Japan and the US is around 2, while it is below 1.5 in the Netherlands and Sweden.
