The incorporation of digital technologies in the energy sector can support progress towards key UK objectives such as achieving Net Zero emissions targets. It can also transform current methods of energy generation, transmission, regulation, and trading. This POSTnote presents an overview of key digital technologies and their main applications in the energy sector. It provides an overview of the potential benefits to using these technologies, and recent developments in this area. It describes the role of data in underpinning digital technologies in the sector, and some of the issues raised by its use. It also discusses broader challenges associated with energy sector digitalisation and measures that could help address them, including issues related to technology, regulation, and impact on consumers.

Coastal management (461 KB , PDF)
Many of the UK’s communities, cultural heritage sites, important ecosystems, infrastructure and other assets are located on its coastline and estuaries. Coastal management policy seeks to reduce the risk to these from coastal change (flooding and erosion), but climate change is increasing storminess and will drive further sea level rise, which will increase hazard on the coast.
Coastal management is a devolved policy area, guided in England by the Flooding and Coastal Erosion Risk Management (FCERM) strategy, published in 2020. Alongside this, a range of policy areas from planning law to building codes govern activity on the coast, and affect how risk is managed. Non-statutory Shoreline Management Plans (SMP) guide management of the coast at a local level. However, in practice many SMP actions are not funded and have not been implemented for some sections of the coast. The FCERM promotes the use of coastal habitats such as salt marsh as a more economically and ecologically sustainable approach to coastal protection when compared to traditional defences such as sea walls. However, questions remain around the long-term capacity of these habitats to protect the coast, particularly with higher sea level rise (above 0.5m). Future sea level rise is an active research area, with significant uncertainties around it’s rate and magnitude. An adaptive management pathway approach is increasingly favoured to account for this uncertainty, allowing for changes in management policy as ongoing monitoring shows the trajectory of coastal change.
Coastal communities are engaged in shaping coastal management policy, but to be accepted and supported, management approaches need to take account of local knowledge and communities’ relationships to place, as well as being ethical and just. Inequality in exposure to and potential impact of coastal hazard follows wider patterns of disadvantage in England. Minority ethnic households, those in ‘post-industrial’ northern towns and cities and low-income households are disproportionally affected by all sources of flooding, and have less capacity to manage risk at an individual or community level.
- Sea level rise will continue over the coming centuries, increasing the frequency and magnitude of coastal hazards.
- Growing coastal populations and the value of assets on the coast are increasing exposure to coastal flood and erosion risk, with a third of people exposed to frequent coastal flooding in the top 20% most vulnerable neighbourhoods.
- Coastal management in England is guided by the new Flooding and Coastal Erosion Risk Management strategy, but it is not clear if the strategy can address the potential scale of future risks.
- Challenges remain around the planning, funding, and delivery of coastal management. Some options may also be challenging to deliver without gaining the acceptance of local communities.

Space-based assets (satellites and the terrestrial ground stations that communicate with them) provide critical support to military and civilian operations. They are vulnerable to unintentional damage and disruption, and to deliberate attack. This POSTnote outlines how the UK uses and accesses satellites, potential risks to satellites, and approaches to mitigation.
The UK Government is introducing Local Nature Recovery Strategies (LNRS) from April 2022 to map where local habitat improvement and restoration could address national-scale environmental objectives. This POSTnote summarises the LNRS approach, including mapping ecological networks, the opportunities for LNRSs to deliver wider benefits to nature and people, and the likely challenges associated with the strategies and their delivery.
