As the world transitions to renewable energy sources, many countries are leading the way in reducing their dependence on fossil fuels. Fossil fuels, including coal, oil, and natural gas, have been the primary energy source for many countries, contributing significantly to their economic development. However, the shift towards renewable energy sources is gaining momentum, driven by the urgent need to address climate change and the finite nature of fossil fuels. While no country is currently completely fossil fuel-free, several nations are making impressive strides in this direction.

What You'll Learn
Iceland is the least dependent on fossil fuels
Iceland's geothermal power is impressive, with 9 out of 10 homes heated by geothermal energy. This has led to the country being among the top ten global producers of geothermal energy. The UN has even suggested that Iceland's transition to renewable energy could be a model for other countries to follow.
Iceland has a small but well-developed green economy, and its government has set ambitious goals for the future. They aspire to make the nation carbon neutral by 2040, with the main obstacles to this goal being road transport and the fishing industry. Iceland's small population and scale of infrastructure have also been seen as potential advantages in transitioning to a hydrogen-based economy, with the country aiming to become the first 'hydrogen society' by 2050.
Despite Iceland's impressive renewable energy sector, the country still faces challenges. Icelanders' car-based culture and reliance on imported oil for transport are significant contributors to fossil fuel usage. Additionally, the country's remote location and high latitude limit its solar power potential, with very little sunlight available in the winter months. However, Iceland continues to lead the way in renewable energy, and its progress provides a promising model for other nations to follow.

Sweden is on track to reach its 2040 goal of 100% fossil-free electricity
Sweden is a global leader in building a low-carbon economy, with the lowest share of fossil fuels in its primary energy supply among all IEA member countries. The country has been successful in its energy transformation through market-based policies that focus on energy efficiency and renewable energy. Notably, Sweden adopted a CO2 taxation policy, which has helped drive decarbonisation across several sectors.
Sweden has set an ambitious target of achieving 100% fossil-free electricity by 2040, which is an extension of its previous goal of 100% renewable electricity generation by the same year. This shift in target is crucial to the government's strategy to meet the expected doubling of electricity demand to approximately 300 TWh by 2040 and attain net-zero emissions by 2045.
Sweden's progress towards its 2040 goal is evident. In 2012, the country achieved its target of 50% renewable energy eight years ahead of schedule. Currently, about 98% of electricity in Sweden is generated from water, nuclear, and wind power. The country's energy policy is well-integrated with its climate objectives, and it has set additional targets to support its journey towards 100% fossil-free electricity. These include EU targets for sectoral emissions reductions, renewable energy, and energy efficiency, as well as a domestic 2030 emissions reduction target for the transport sector.
However, challenges remain. Sweden's approach to energy sector development is largely market-led, and the scarcity of sectoral strategies and limited policy levers create uncertainties in meeting the targets. For instance, the government's focus on nuclear power, while having its merits, should not undermine the potential of other generation sources, particularly wind energy. Simplifying environmental permitting and addressing local acceptance issues could accelerate the development of wind power projects, which are already economical to build without additional government support.

Germany targets close to 100% renewable energy by 2035
As of 2017, Iceland is the country least dependent on fossil fuels, with 89% of its energy derived from non-fossil fuel sources. France, Switzerland, Costa Rica, Norway, El Salvador, and New Zealand are also among the countries least dependent on fossil fuels. Sweden is on track to reach its 2040 goal of 100% fossil-free renewable electricity production.
Germany is also making significant strides towards a fossil fuel-free future. In 2022, Germany's new government set an ambitious target of achieving 80% renewable power by 2030 and close to 100% by 2035. This is part of their "biggest energy policy reform in decades", with renewables at its centre. Germany aims to fulfil all its electricity needs with renewable sources by 2035, compared to its previous target of abandoning fossil fuels "well before 2040".
To achieve this goal, Germany plans to increase its use of wind and solar power. By 2030, Germany aims to double its onshore wind energy capacity to 110 gigawatts (GW), triple its solar energy capacity to 200 GW, and reach 30 GW of offshore wind energy, which is equivalent to the capacity of 10 nuclear plants. This drive towards renewable energy has been accelerated by Russia's invasion of Ukraine, as Germany aims to reduce its dependence on Russian fossil fuels.
Germany's Climate Law sets out a framework for reaching net-zero emissions by 2045. The country has been an early leader in offshore wind and solar PV and phased out nuclear power in 2023. Germany is also deploying efforts to reduce energy consumption by about 500 TWh by 2030, corresponding to around one-fifth of its energy consumption in 2022.

Uruguay's renewable energy revolution
Uruguay has undergone a remarkable renewable energy revolution, transitioning from fossil fuel dependence to sourcing over 90% of its electricity from renewables in just over a decade. This shift has not only reduced the country's environmental footprint but also created economic opportunities and served as a model for other nations seeking to embrace sustainable energy practices.
Once heavily reliant on imported fossil fuels, Uruguay has successfully broken free of this dependence. In the early 2000s, the country faced an economic and energy crisis, with rising fossil fuel prices and increasing energy demand. Recognizing the need for a sustainable alternative, Uruguay's Energy Secretary, Ramón Mendéz Galain, a physicist by training, led the country in an ambitious energy revolution.
Uruguay's renewable energy transition focused primarily on wind power, which now accounts for 40% of the country's energy capacity. This was complemented by solar and biomass energy sources, with hydropower also playing a significant role. The country's geography, with its powerful rivers and vast grasslands, proved ideal for utilizing these renewable sources effectively.
The results of Uruguay's renewable energy revolution have been impressive. The country has reduced its greenhouse gas emissions, with Uruguayans emitting 30 times less than the world average per inhabitant. Additionally, over 50,000 jobs have been created, and energy production costs have been halved, stabilizing electricity costs for consumers.
Uruguay's success serves as a compelling case study for other nations. It demonstrates that a rapid transition to renewable energy is not only possible but also economically beneficial. By empowering local communities, rewriting the rules of energy markets, and building political will and trust in renewables, Uruguay has blazed a trail for other countries to follow in the fight against climate change.
