Italy’s power mix is heavily reliant on natural gas – it accounts for about a 50% share in 2021 – mostly imported from Russia. While the ongoing war is an opportunity for Italy to change its policy to invest more in cheap renewables and simultaneously become less reliant on expensive fossil fuels imports, the country seems to be implementing a plan of replacing gas with gas. This could have implications for the long-term price of energy and creates the risk of prolonging, or even stranding, fossil fuel infrastructure.19
The share of renewable energy sources in the Italian power mix has increased steadily in the last decade as Italy aims to achieve a 72% renewable share of electricity generation by 2030.12,16 In contrast, the contribution of coal has declined in recent years as Italy aims to phase out coal from its power mix by 2025.12,16
To be consistent with 1.5°C compatible pathways, renewable energy’s share of Italy’s power generation would need to reach between 82-87% by 2030 and 100% by 2040, compared to around 35-40% in 2019.
Natural gas would need to be phased out by 2040 at the latest, while coal would need to be phased out before 2029. Italy already targets a 2025 phase out deadline for coal. 1.5°C pathways require a decline in power sector emissions intensity of 87-89% below 2005 levels by 2030, and would reach -50 gCO₂/kWh by 2050. In the model used here this is mostly through the use of BECCS, however the sustainability of this has not been examined and other options such as Direct Air Capture (DAC) could also be used. Delaying phasing out fossil fuels in the power mix would require the country to rely more heavily later on such costly negative emissions technologies later on.

27 While global cost-effective pathways assessed by the IPCC Special Report 1.5°C provide useful guidance for an upper-limit of emissions trajectories for developed countries, they underestimate the feasible space for such countries to reach net zero earlier. The current generation of models tend to depend strongly on land-use sinks outside of currently developed countries and include fossil fuel use well beyond the time at which these could be phased out, compared to what is understood from bottom-up approaches. The scientific teams which provide these global pathways constantly improve the technologies represented in their models – and novel CDR technologies are now being included in new studies focused on deep mitigation scenarios meeting the Paris Agreement. A wide assessment database of these new scenarios is not yet available, thus we rely on available scenarios which focus particularly on BECCS as a net-negative emission technology. Accordingly, we do not yet consider land-sector emissions (LULUCF) and other CDR approaches which developed countries will need to implement in order to counterbalance their remaining emissions and reach net zero GHG are not considered here due to data availability.

Investments
Demand shifting towards the power sector
The 1.5°C compatible pathways analysed here tend to show a strong increase in power generation and installed capacities across time. This is because end-use sectors (such as transport, buildings or industry) are increasingly electrified under 1.5°C compatible pathways, shifting energy demand to the power sector. Globally, the “high energy demand” pathway entails a particularly high degree of renewable energy-based electrification across the various sectors, and sees a considerable increase in renewable energy capacities over time. See the power section for capacities deployment under the various models.
Italyʼs renewable electricity investments
Billion USD / yr
Yearly investment requirements in renewable energy
Across the set of 1.5°C pathways that we have analysed, annual investments in renewable energy excluding BECCS increase in Italy to be on the order of USD 5 to 41 billion by 2030 and 9 to 55 billion by 2040 depending on the scenario considered. The ‘high energy demand, low CDR reliance’ pathway shows a particularly high increase in renewable capacity investments, which could be driven by an increase of electrification of end-use sectors and growing energy demand. Other modelled pathways have relatively lower investments in renewables and rely to varying degrees on other technologies and measures such as energy efficiency and negative emissions technologies, of which the latter can require high up-front investments.
