Estonia may not be sitting on massive oil deposits, but it does have plenty of wind, water, and, occasionally, sun. That may be enough to turn this country of islands, bogs, and ingenuity into a hydrogen energy powerhouse, if its talents
Thanks to the use of oil shale and, increasingly, renewable fuels, we are able to satisfy our country''s energy needs to a large extent. We are working to ensure that even in the conditions of stricter energy and climate policy than before, Estonia is able to maintain its energy independence and increase it even more. This is because the target
Reaching Estonia''s ambitious targets for 2030 is possible but requires determined and timely action to decarbonise the country''s electricity and transport sectors. Estonia also has considerable scope to review energy taxation of all fuels to better reflect their carbon content with a view to accelerating the switch to low-emission

where: (delta_{0}) is the mean square deviation of wind power; (delta_{1}) is the mean square deviation of the total output power of the wind and solar power in the ECS connected at a certain ratio. When the maximum value is obtained, the capacity of ECS can make full use of the natural complementary characteristics of wind and solar in time and space.

This IEA Energy Policy Review comes at a critical moment for Estonia, which is facing notable challenges amid the climate and energy crises and the Russian Federation’s invasion of Ukraine.
The IEA commends Estonia for the steps it has taken to end all remaining energy trade with Russia while ensuring regional energy security, and for the work to accelerate the energy transition, including setting a 2050 carbon-neutrality target and a target for 100% of annual electricity demand to be covered by renewable energy by 2030.
Estonia is on the brink of a major energy transition that will involve a substantial change in the role of domestically produced oil shale in the country’s future energy mix. The transition will require Estonia to carefully balance social, environmental, economic, and energy security considerations.
In 2021, natural gas accounted for just 8.6% of total energy supply (versus the IEA average of 30%) and came mostly from Russia. In 2022, Estonia took swift actions to end its reliance on Russian gas and secure regional gas supply and reduced gas demand to 5.8% of total energy supply.
Estonia has taken steps to ensure regional gas security while working to reduce its gas demand and decarbonise its gas supply. Natural gas plays a relatively minor role in Estonia’s energy system and is used mostly for heating.
A major electricity system transformation is needed to achieve the 100% renewable electricity target and put Estonia on the path to climate neutrality.
