Adapt or Perish in Climate Change: Renewable Energy Revolution Powering a Sustainable Future

 Chapter 5: Renewable Energy Revolution: Powering a Sustainable Future

Renewable energy resources power a sustainable future

Renewable energy has become a cornerstone of the global effort to combat climate change, reduce environmental degradation, and promote sustainable development. Unlike fossil fuels, which are finite and polluting, renewable energy sources harness the natural, abundant forces of the Earth, such as sunlight, wind, and water, to produce clean and sustainable power.

This section explores why transitioning to renewable energy is urgent and necessary for addressing the interconnected crises of climate change, energy insecurity, and environmental harm.

Energy and Climate Change

Energy production and consumption are the primary drivers of global greenhouse gas (GHG) emissions, accounting for approximately 73% of global emissions (International Energy Agency [IEA], 2022). Fossil fuels—coal, oil, and natural gas—dominate the global energy mix, releasing vast amounts of carbon dioxide (CO₂) and methane (CH₄) into the atmosphere when burned. These emissions are the primary cause of global warming, leading to more frequent and severe heatwaves, storms, droughts, and rising sea levels.

The 2015 Paris Agreement set a target of limiting global warming to well below 2°C, with efforts to keep it below 1.5°C. Achieving this goal requires a rapid and significant reduction in fossil fuel use and an accelerated transition to renewable energy. According to the Intergovernmental Panel on Climate Change (IPCC), renewable energy must account for 70–85% of electricity generation by 2050 to meet these targets (IPCC, 2021).

The Limitations of Fossil Fuels

Fossil fuels are the leading contributors to climate change and pose various environmental and social challenges. As finite resources, their extraction becomes increasingly costly and harmful to the environment, leading to resource scarcity, which can create geopolitical tensions as nations vie for access to these reserves.

The combustion of fossil fuels also results in significant pollution, releasing harmful air pollutants such as particulate matter, sulfur dioxide, and nitrogen oxides. According to the World Health Organization, these pollutants cause approximately 7 million premature deaths each year due to respiratory and cardiovascular diseases.

Moreover, the extraction and use of fossil fuels bring about severe environmental degradation, including deforestation, habitat destruction, and water contamination. Incidents like oil spills and the impacts of coal mining and natural gas fracking can have long-lasting, detrimental effects on ecosystems.

Additionally, heavy reliance on fossil fuels makes countries susceptible to price fluctuations and supply disruptions, as illustrated by the energy crisis that arose from the 2022 Russia-Ukraine war. This situation highlights the urgent need for stable and diversified energy sources.

The Advantages of Renewable Energy

Renewable energy offers a sustainable and equitable solution to the limitations of fossil fuels, with significant environmental, economic, and social benefits:

Renewable energy presents a sustainable and equitable alternative to fossil fuels, offering various environmental, economic, and social advantages. One of the most significant environmental benefits is the minimal greenhouse gas emissions produced during the operation of renewable sources like solar and wind energy. This makes them crucial for decarbonizing the energy sector.

Additionally, renewable resources are abundant and naturally replenished; for instance, the sun emits more energy in just one hour than the entire world consumes in a year, illustrating the immense potential of solar power.

Investing in renewable energy also promotes energy independence, enabling countries to decrease their reliance on imported fossil fuels and enhance their resilience to fluctuations in global markets. Economically, the renewable energy sector is a potent engine for job creation, employing 12.7 million people globally in 2021 and with the prospect of generating millions more as investments grow (International Renewable Energy Agency [IRENA], 2022).

Furthermore, transitioning to renewable energy offers substantial public health benefits. By reducing air pollution, cleaner energy sources can prevent thousands of premature deaths yearly, highlighting the intersection of environmental practices and public health (Harvard T.H. Chan School of Public Health, 2021). Overall, the shift toward renewable energy is vital for a sustainable future.

Addressing the Urgency

The accelerating impacts of climate change emphasize the need for renewable energy. The last decade has seen record-breaking global temperatures, devastating wildfires, and catastrophic flooding. According to the United Nations Environment Programme (UNEP, 2021), current policies and actions are insufficient to meet the Paris Agreement goals, and a rapid expansion of renewable energy is essential to close this gap.

Energy demand is expected to grow by 50% by 2050, driven by population growth and economic development, particularly in emerging economies (IEA, 2021). Meeting this energy demand sustainably requires a shift to clean energy sources that can power the global economy without exacerbating climate risks.

The Global Commitment to Renewable Energy

Governments, businesses, and international organizations increasingly acknowledge the vital role of renewable energy in meeting climate and development objectives.

A notable trend is the commitment of over 130 countries to achieve net-zero emissions by mid-century, with renewable energy being central to these plans. In addition, global investments in renewable energy hit a record high of $366 billion in 2021, underscoring the growing confidence in the sector's potential (BloombergNEF, 2022).

Furthermore, international collaborations, such as the International Solar Alliance and the Clean Energy Ministerial, promote global cooperation to expedite the deployment of renewable energy solutions.

Adapt or Perish in Climate Change: Fossil Fuels and Financial Costs

 The Hidden Subsidies: Fossil Fuels and Financial Costs

Fossil fuels processing structure

Governmental subsidies and substantial financial support for fossil fuel use are partly, if not hugely, responsible for maintaining their dominant spot in the global energy system. Often hidden from public scrutiny, such subsidies artificially lower the cost of fossil fuels, which could distort markets and delay the transition to clean energy sources.

This section explores the various forms of fossil fuel subsidies, their economic and environmental impacts, and the opportunity costs associated with maintaining these subsidies in the face of the climate crisis.

What Are Fossil Fuel Subsidies?

Fossil fuel subsidies are financial mechanisms that many governments employ to aid and sustain coal, oil, and natural gas production and consumption. These financial mechanisms are created in various forms, such as direct financial support, wherein governments pay or provide grants to fossil fuel producers (companies) so that they can effectively lower production costs and promote exploration and processing.

Subsidies also encompass tax breaks and low-interest loans to facilitate the extraction of more fossil fuels.

Subsidies work when consumers continue to play their role by sustaining fossil fuel usage. Most governments artificially reduce the cost of fossil fuels so that consumers continue to use them, sustaining their production.

Also, governments cover part of the expenses as part of the subsidies to keep fossil fuel energy prices affordable and encourage more consumers.

Further, fossil fuels carry externalized costs that are not observable in their market prices. These non-observable costs include air pollution, health issues, and the consequences of climate change, which would ultimately burden taxpayers through increased public healthcare costs and disaster recovery efforts.

Economic Impacts of Fossil Fuel Subsidies

Governments defend fossil fuel subsidies to promote economic growth and secure energy access for industries and their population. However, the long-term economic consequences of fossil fuel subsidies are largely detrimental.

The economic impact of fossil fuel subsidies is substantial and often detrimental in the long term. Globally, fossil fuel subsidies were estimated to reach approximately $5.9 trillion in 2020, representing about 6.8% of global GDP (IMF, 2021).

For example, in 2022, the United States spent a staggering $757 billion on helping fossil fuel companies, according to data from the International Monetary Fund. This subsidy includes $3 billion in direct financial aid and $754 billion in hidden costs, like health issues and environmental damage that affect everyone, not just the companies producing the fuels.

In fiscal year 2016, the government made slightly more money from taxes on natural gas and oil than it spent on subsidies, with a surplus of $1.1 billion. However, by fiscal year 2022, the situation changed dramatically, with subsidies surpassing revenue by $2.1 billion, resulting in a loss for the government. Additionally, tax support for coal dropped significantly, falling from $1.9 billion in 2016 to just $590 million in 2022 (Brind'Amour, 2024).

One major issue with subsidizing fossil fuels is that it distorts the market, reducing the cost of fossil fuels and making renewable energy sources less competitive. This scenario hinders investors and consumers from supporting cleaner technologies and heightens the reliance on carbon-intensive energy systems.

Further, the constant investment in fossil fuel infrastructure and production poses the risk of creating stranded assets. These assets are facilities that will become obsolete and unprofitable as the world slowly shifts towards a low-carbon-intensive energy economy. Transitioning to low-carbon solutions later on can lead to substantial economic losses, particularly for countries with massive fossil fuel investments.

Additionally, subsidies may impose heavy fiscal burdens on the government's national budgets. The fiscal burdens usually divert vital resources such as public services, including healthcare, education, and infrastructure. A concrete example is India's 2020 fossil fuel subsidies, which exceeded $10 billion. This massive amount could have been better allocated to sustainable development projects.

The International Monetary Fund (IMF) indicates that removing these subsidies could help countries redirect significant funds towards renewable energy sources and public health initiatives, potentially improving overall economic resilience (IMF, 2021).

Environmental and Social Costs of Subsidies

A government's fossil fuel subsidies significantly negatively impact environmental health and social equity. Subsidies incentivize their increased production and consumption, which lower the cost of fossil fuels but would intensify carbon emissions. According to research, removing the subsidies could decrease global CO₂ emissions by 10% annually.

Also, reliance on subsidized fossil fuels not only intensifies carbon emissions but also air pollution levels, which can cause serious health issues, including respiratory and cardiovascular illnesses. The healthcare costs associated with these illnesses, along with lost productivity, disproportionately burden low-income communities.

In addition, subsidies for fossil fuels would only benefit wealthier households and companies. A study by the International Monetary Fund (IMF) highlights that fossil fuel subsidies disproportionately benefit higher-income households. According to their analysis, the wealthiest 20% of households capture around 43% of total subsidies in most countries. This trend indicates that wealthier households and corporations are the primary consumers and beneficiaries of fossil fuel subsidies, exacerbating inequality (Coady et al., 2019).

Subsidizing this particular energy is a misallocation of funds that would exacerbate income inequality and inhibit fair access to clean energy alternatives. This would ultimately sabotage the efforts to create a more just energy landscape for everyone.

The Opportunity Costs of Fossil Fuel Subsidies

Allocating national funds or other resources to fossil fuel subsidies will cost massive opportunities as the resources could be redirected to promote sustainable and just energy transitions and other climate adaptation ambitions. Redirecting subsidies to promote renewable energy would strongly accelerate the use of clean energy technologies, including solar and wind power.

A tiny portion of global fossil fuel subsidies could provide massive access to solar energy in many developing countries, helping them gain more renewable energy while reducing gas emissions.

According to the International Monetary Fund (IMF, 2021), the global cost of fossil fuel subsidies was estimated at around $5.9 trillion in 2020, representing about 7% of global GDP. These funds could otherwise be allocated towards renewable energy development, healthcare, or education, potentially yielding greater long-term benefits for society.

Furthermore, the OECD (2021) emphasized that redirecting subsidies to clean energy could help reduce greenhouse gas emissions, contributing to climate change mitigation efforts. Their analysis suggested that reforming fossil fuel subsidies could reduce CO2 emissions by up to 15% by 2030.

Further, reforming fossil fuel subsidies would free funds for major climate adaptation projects, such as building resilient infrastructure, enhancing disaster preparedness, and supporting vulnerable communities.

Additionally, investing in renewable energy and energy efficiency would create more job opportunities per dollar spent than investing in fossil fuel industries. By redirecting subsidies, we can stimulate economic growth while also reducing greenhouse gas emissions.

Challenges to Phasing Out Fossil Fuel Subsidies

The push for reducing fossil fuel subsidies presents clear economic and environmental benefits; however, various political and social challenges often impede these reform efforts. Politically, the fossil fuel industry exerts considerable influence through lobbying and campaign financing, making it difficult to implement subsidy reforms. Politicians may hesitate to support such changes due to fears of public backlash or potential negative impacts on economically dependent regions.

On the social front, removing subsidies can increase energy prices, disproportionately affecting low-income households that rely on affordable fuel and electricity. Without adequate compensation mechanisms, these reforms risk exacerbating energy poverty and causing social unrest.

In many countries, fossil fuels are crucial to the economy, providing essential revenue, jobs, and energy security. Consequently, phasing out subsidies necessitates careful planning to minimize economic disruptions and ensure a just transition for communities reliant on the fossil fuel sector.

Examples of Successful Subsidy Reform

Despite the resistance to adapting to the urgent demands of climate change, several countries and regions have already successfully reformed their fossil fuel subsidies, providing models and lessons for others to emulate.

Indonesia

This country successfully phased out gasoline subsidies in 2015 by redirecting savings toward eco-friendly infrastructure development and social programs. This reform proved effective, reducing the fiscal burden while improving public services to its vast population.

Iran

This Middle Eastern nation successfully reformed its subsidy program in 2010, replacing energy subsidies with direct household cash transfers. Their effective strategy has helped mitigate the social impacts of energy price hikes and overcome the challenges.

Sweden

This European nation eliminated its subsidies for fossil fuels in the 1990s. It successfully implemented a carbon tax, incentivizing renewable energy adoption and reducing emissions without disrupting economic growth and social development.

Summary

Fossil fuel subsidies are a major barrier to reaching global climate goals. They perpetuate dependence on carbon-intensive energy sources and exacerbate environmental and social challenges.

If fossil fuel subsidies were phased out strategically, there would be ample opportunity to redirect resources toward sustainable energy solutions, improve public health, and address social inequalities.

To realize the transition from heavy carbon resource users to a more renewable and environmentally friendly future, we need to overcome political resistance, address social concerns, collaborate with relevant institutions, and ensure a just transition for all stakeholders. As we move toward a low-carbon future, reforming and reducing fossil fuel subsidies are crucial in creating and establishing an equitable and sustainable energy system.
