Decarbonisation and renewable energies

Climate change problematic It is one of the greatest challenges facing today's society. The need to significantly reduce greenhouse gas emissions and move toward more sustainable economic models has driven the search for innovative solutions in all sectors. decarbonization and the deployment of renewable energy They have become the focus of public, economic and political debate, paving the way for a carbon-free economy.

In this article, we will take a comprehensive look at the keys to achieving a decarbonized economy: what it means to change our energy and production model, what short-, medium-, and long-term goals have been set, what measures Spain and the European Union have adopted, and how technology, innovation, and collective commitment can make this change possible. We will learn about both the challenges and opportunities that the ecological transition offers for businesses, citizens, and regions.

What is decarbonization?

La decarbonization It is a process that seeks drastically reduce carbon emissions—mainly carbon dioxide (CO2)—into the atmosphere. These emissions come primarily from the use of fossil fuels (coal, oil, and natural gas), which have so far sustained modern economies. Decarbonization involves a profound change in the energy and productive structure: progressively replace polluting sources with renewable ones, improve efficiency and transform mobility, industry, agriculture and cities.

The central objective of decarbonization is moving towards an economy and society with low or zero net emissions, thus combating global warming and promoting environmental sustainability. It's not just about reducing "direct" emissions, but also addressing consumption, production, and resource management habits across all sectors.

According to the definition of the Intergovernmental Panel on Climate Change (IPCC), decarbonize It means that countries, regions, companies, or individuals modify their processes and consumption so that the carbon footprint on the economy and the environment is minimal or zero. It's much more than a slogan: it's a comprehensive and cross-cutting transformation.

Moving towards a clean and resilient economy It requires the involvement of governments, the private sector, and citizens, as well as a long-term vision combined with immediate measures. As a member of the EU, Spain has made ambitious commitments in this area, following the roadmap outlined by the Paris Agreement and the UN's 2030 Agenda.

Spain and the European Union: objectives and commitments for climate neutrality

Decarbonization and renewable energy: keys to achieving a carbon-free economy-9

In recent years, both the European Union and Spain have strengthened their emission reduction targets, driven by climate urgency and international obligations. The Paris Agreement has established the global framework whose ambition is updated periodically.

The European Commission has set a target for 2030 greenhouse gas emissions reduction target of 55% compared to 1990, and achieve the climate neutrality in 2050Spain has adopted these commitments, even exceeding European requirements in some respects.

El Strategic Energy and Climate Framework Spanish, approved since 2019, contains three main axes: mitigation (reducing emissions), adaptation (responding to the already inevitable effects) and just transition (protecting the most vulnerable sectors and regions). This framework provides regulatory coverage and certainty for businesses, investors, and citizens, coordinating all the measures in place.

One of its milestones is the Long-Term Decarbonization Strategy 2050, which sets as a goal reduce greenhouse gas emissions by 90% compared to 1990 by that year. The remaining 10% should be absorbed by natural sinks such as forests or wetland restoration. Roadmap It will be finalized and revised every decade, adapting to the evolution of technology and the international context.

On a smaller time scale, the National Integrated Energy and Climate Plan (PNIEC) 2021-2030 sets intermediate objectives: a 23% reduction in CO2 emissions compared to 1990, an estimated improvement in energy efficiency of 39,5%, achieving 42% renewables in final consumption and 74% in the electricity mix.

The leading role of renewable energies

La renewable energy penetration It is the cornerstone of decarbonization. Spain, due to its climate and topography, has enormous potential to exploit clean sources such as solar photovoltaic, solar thermal, onshore and offshore wind, hydroelectric, and biomass.

The national strategy foresees that in 2050 97% of final energy consumption comes from renewable sourcesIn the electricity sector, decarbonization will be complete, allowing for the elimination of coal and nuclear power plants. Furthermore, in transportation and domestic air conditioning, renewable energy quotas of 79% and 97% are planned, respectively.

The development of renewables is accompanied by other key vectors, such as wave energy production and the potential of marine geothermal energy.

All this development is framed within the idea of strategic autonomy, seeking to reduce dependence on energy imports. It is estimated that Spain will go from importing 73% of its energy in 2018 to only 13% in 2050, which will represent a cumulative saving of more than €340.000 billion in fossil fuels.

Plans and concrete measures to decarbonize the Spanish economy

Decarbonization requires a battery of multisectoral policies, plans and strategiesThe Energy and Climate Strategic Framework is structured around the following key instruments:

  • Climate Change and Energy Transition Law: provides the legal basis for all climate action measures, facilitating economic adaptation and ensuring ambitious medium- and long-term goals.
  • National Integrated Energy and Climate Plan (PNIEC): sets targets for emission reduction, renewable penetration, and energy efficiency through 2030, serving as a guide for public and private investments.
  • National Plan for Adaptation to Climate Change: promotes the coordination of public policies to reduce the vulnerability of territories and sectors to the already inevitable climate impacts.
  • Just Transition Strategy: ensures that workers and regions affected by the closure of fossil fuel industries are supported through training, investment, and employment alternatives to avoid negative impacts on social cohesion.
  • Energy Storage Strategy: identifies needs and measures to deploy storage technologies that ensure the integration of renewables and the stability of the electrical system.
  • Sectoral roadmaps: self-consumption, renewable hydrogen, biogas, offshore wind, mineral raw materials management, etc., which specify actions and deadlines for each area of ​​transformation.
  • Power grid planning: new electrical infrastructure to ensure the integration of renewables and security of supply.
  • National strategy against energy poverty: includes measures to protect the most vulnerable groups, ensuring the effective right to energy.
  • Recovery, Transformation and Resilience Plan (PRTR): directs massive investments, especially with European Next Generation EU funds, towards the ecological transition, digitalization and social cohesion.

Sectoral measures to move towards climate neutrality

Could more have been done to prevent the blackout?-6

Decarbonization requires action across all economic sectors. Let's look at the key areas:

Transformation of the electrical system

El electric sector It is the main driver of the transition. The planned closure of coal and nuclear power plants, the massive integration of renewables, and the deployment of storage infrastructure and smart grids will allow electricity generated by 2050 to be 100% renewable. In turn, increased electrification in transportation, air conditioning, and industrial processes will facilitate a widespread reduction in emissions.

Industry and circular economy

La industry It represents a particular challenge given its energy intensity and complex production processes. Decarbonization here requires:

  • Adopting Clean technologies and replacement of fossil fuels with renewable ones.
  • impulse of the circular economy, promoting the reuse and recycling of materials to reduce waste and the use of virgin resources.
  • Development and application of carbon capture, utilization and storage technologies (CCUS) in processes where decarbonization is more difficult.
  • Promotion of alternative raw materials and digitalization of processes.
  • Constant support to the I + D + i to position the Spanish industry in global value niches related to the energy transition.

Mobility and transport

El Services, responsible for a large part of emissions, must be transformed with:

  • Progressive electrification of the private and public vehicle fleet.
  • Boost of low or zero emission vehicles (electric cars, plug-in hybrids, hydrogen, etc.).
  • Development of efficient public transport, shared and active mobility (bicycling, walking) for more livable cities.
  • Innovation in alternative fuels (sustainable biofuels, green hydrogen) for heavy and freight transport.
  • Integration of urban planning to reduce the need for polluting travel.

Building and energy efficiency

The housing stock accounts for a significant portion of energy consumption. Decarbonizing this sector requires:

  • Massive and efficient rehabilitation of existing buildings (better insulation, efficient installations, intelligent systems).
  • New building with almost zero energy consumption.
  • Deployment of renewable air conditioning and heating (efficient heat pump, solar thermal systems, renewable heating and cooling networks).
  • Boosting the European "renovation wave" to double renovation rates and generate green jobs in the construction sector.

Agriculture, livestock and waste management

The agricultural sector and waste management present challenges and opportunities:

  • Improvement of crop, fertilizer and manure management to reduce emissions of methane and nitrous oxides.
  • Promotion of biogas and biomethane from organic waste.
  • Digitization and use of smart technologies for irrigation, fertilization and farm management.
  • Advance towards Mediterranean diet and reducing food waste.
  • Recovery and restoration of soils and wetlands as carbon sinks.

Furthermore, the circular economy and waste reduction are key to reducing pressure on resources and limiting emissions associated with landfills.

Financial and investment instruments for the ecological transition

The decarbonization process involves mobilizing significant economic and financial resources, both public and private. The main sources include:

  • European funds Next Generation US channeled through the Recovery, Transformation and Resilience Plan.
  • Green loans and bonds, socially responsible investment funds and innovative banking products to finance energy transition projects.
  • Tax incentives for private investment in clean technologies, efficiency, and renewables.
  • I support I + D + i in research centers, universities and companies to accelerate the arrival of disruptive solutions.
  • Medium- and long-term planning to provide certainty and clear signals to investors.

The estimated investment needed between 2031 and 2050 will be around €500.000 billion, of which approximately €300.000 billion will be allocated directly to implementing the Decarbonization Strategy. This is in addition to the €250.000 billion allocated to the National Economic and Social Plan (PNIEC) for the period 2021-2030.

Ensuring a just transition and social cohesion

One of the fundamental concerns is to ensure that the change in the energy and production model does not leave behind workers, sectors, or territories that are most dependent on fossil fuels. Therefore, the concept of just transition It is central to the Spanish and European strategy.

This implies:

  • Anticipate and plan the closure of polluting facilities with viable industrial and labor alternatives.
  • Launch training and professional reorientation plans for workers affected by the transformation.
  • Protect vulnerable regions through targeted investments and rural development programs.
  • Incorporate gender perspective and equality in all public policies, promoting the participation of women in jobs and strategic sectors of the ecological transition.
  • Address the demographic challenge and depopulation by generating new employment opportunities and economic activity in rural areas.

La social and territorial justice It is essential to ensure the success and social acceptance of the ecological transition.

Socioeconomic and environmental benefits of decarbonization

polluting emissions

The benefits of decarbonization extend beyond reducing emissions and combating climate change. Among the most significant positive impacts are:

  • Green job creation: It is estimated that the adoption of the planned measures could generate around 300.000 net jobs annually by 2050.
  • Savings on energy imports: The drastic reduction in dependence on hydrocarbons could lead to savings of 344.000 billion euros.
  • Increased industrial competitivenessThe modernization and digitalization of industrial processes will strengthen Spain's leadership in high-value-added sectors such as renewables, storage, and digitalization.
