                …demand and a rapid expansion of renewable electricity generation, along with increased energy efficiency. There is a strong focus on reducing energy import dependency and maintaining affordable access to energy. In the longer-term Portugal is aiming for hydrogen to play a major role in achieving carbon neutrality.
                Portugal has made notable progress on decarbonising electricity generation and on electrification of building energy demand, however, the country’s energy mix is still dominated by fossil fuels. The transport, industry and buildings sectors all have considerable work ahead of them to meet Portugal’s targets for increasing the share of renewables…

                Portugal Climate Resilience Policy Indicator

                Country summary Across all Portugal’s regions, average annual air temperature has risen more than 0.3°C per decade since the 1970s. This upward trend is expected to persist throughout the 21st century, and the number of very hot days and tropical nights is also projected to be higher than during 1971-2000. The temperature rise could affect the country’s energy supply by reducing the generation and efficiency of thermal power plants as well as the electricity grid’s efficiency and maximum transmission. Higher temperatures could also affect energy demand by prompting the wider use of air conditioning, placing…
