As the climate crisis exacerbates globally, governments, especially from countries with the cleanest air in the world, are diverting greater focus towards achieving net-zero carbon emission targets by 2050. However, according to an analysis by McKinsey and Company, achieving these goals will necessarily require greater investment in electricity generation via renewable energy sources. However, according to Deloitte, in 2022, renewable energy growth was significantly hampered in the US, which is one of the countries with the cleanest air in the world, due to rising costs and project delays, which in turn were driven by global supply chain disruptions, skyrocketing inflation, increasing interest rates, glaring uncertainties in trade policies, and interconnection delays. Nevertheless, with the passage of the Inflation Reduction Act and increasing demand, robust growth within the renewable energy industry is expected in 2023. Some of the largest players in the renewable energy sector which are likely to be affected by these trends are NextEra Energy Inc. (NYSE:NEE), General Electric Co. (NYSE:GE), and Plug Power Inc. (NASDAQ:PLUG). To delve into further detail about the global clean energy sector in 2023, check out our coverage of the 11 Most Undervalued Renewable Energy Stocks To Buy According To Hedge Funds.
Within the next decade, a report by McKinsey estimates that global renewable energy capacity will drastically increase to more than 8,800 gigawatts. Of this, the vast majority will be derived from onshore wind and solar power. However, the report also points out that additional solar panels and onshore wind turbines will require substantial land space, the overall implications of which are ominous. Developers will need to continuously identify new sites at a time when the availability of suitable, economically desirable land is dire. Further constraints that are likely to hamper the growth of the global renewable energy sector are different regulatory and sustainability limits, the upsurge in land prices globally, long and unpredictable development timelines, and increased grid congestions.
Clean Energy Transition in the Oil and Gas Industry: An Analysis
Since the burning of fossil fuels like oil and gas is one of the greatest sources of carbon emissions and with climate change assuming a higher priority for countries with the cleanest air in the world, efforts to impose a sustainable transition to a lower-carbon energy model are underway and require fundamental shifts in how energy is produced and consumed globally. These shifts require strategic adjustments by businesses. According to an article by McKinsey, oil and gas companies which have long relied on fossil fuels for electricity generation are not spared from this global transition and find themselves needing to navigate an environment in which incredibly strict carbon-reduction targets are likely to impact investment decisions. However, the oil and gas industry is still largely uncertain about where to support initiatives like offshore generation, EV charging, and hydrogen production and development. As a result, operating models for new and legacy companies are undergoing drastic transformations in the face of competition from companies like NextEra Energy Inc. (NYSE:NEE), General Electric Co. (NYSE:GE), and Plug Power Inc. (NASDAQ:PLUG).
According to McKinsey's Global Energy Perspective 2022, fossil fuels like oil and natural gas are widely projected to sustain a significant share of the energy mix at least till 2050, partly due to their methods of combining affordability and security of supply. Regardless, the report still postulates that the oil and gas industry is adequately positioned to play a meaningful role in the global energy transition effort. Some of the main reasons for this are their massive global footprint, the risk appetite of their investors, their expansive balance sheets and cash positions, and their long-standing relationships with energy consumers and stakeholders. A quick analysis of how strategic choices can aid in the implementation of a sustainable power value chain reveals three primary ways oil and gas companies can lead in the global energy transition effort.
One of the primary ways in which they can do this is by constructing an operational model whereby customer centricity is at the core. Business models tend to constantly evolve as innovation shapes technology and services landscapes worldwide. Oil and gas companies can leverage their existing business and deep technical capabilities to aid in creating value in key segments of the energy transition, all the while creating specific and integrated customer offerings that are tailored to individual requirements. This customer centric approach ensures oil and gas players enter production when demand is rising, invest capital in projects best suited to consumer needs, and help define a unique operating model. To know more about some of the measures the oil and gas industry is taking to reduce their carbon footprint substantially, check out our article on Top 20 Countries with the Highest Oil Consumption.
Secondly, the oil and gas sector must implement energy management and risk-exposure practices to contend with fluctuating prices, turbulent geopolitical circumstances and demand shocks. As a result, the industry has developed a robust and adaptable risk culture that continuously plays into investment decisions. Investors in renewables have already shown substantial tolerance to the risks of exposure to power markets, as evidenced by the 2021 Uri winter storm in the United States.
Thirdly, oil and gas companies need to offset geopolitical fluctuations by diversifying their product portfolios and optimize risk returns. Balancing risk exposure across entire portfolios can improve a company's risk/return profile, compared with non-diversified portfolios. Furthermore, through diversified portfolios, companies can improve their project returns through higher leverage over countries with the cleanest air in the world.
Three Trends in the Renewable Energy Industry: An Overview
According to Deloitte, skyrocketing demand in 2023 could present serious problems for the growth of the renewable power industry through its exacerbation of supply chain disruptions and interconnection bottlenecks, thereby driving prices further up and extending project deadlines. Furthermore, clogs in the transmission belt could further hamper industry growth until capacity is substantially expanded. The report highlights three major evolving trends and opportunities that could help the industry navigate headwinds and increase growth in 2023, setting the stage for faster growth in 2024.
One primary trend that is instantly apparent is that rising clean energy component manufacturing could grease supply chain clogs over a short period of time. Currently, American manufacturing does not meet the renewable energy sector's needs for clean energy components held up by sustainable domestic supply chains. Since then, the Inflation Reduction Act 2022 has exacerbated new plant announcements and has encouraged significant investment. This points towards a favorable environment for renewable energy companies in the longer term in countries with the cleanest air in the world.
Another trend that cannot be ignored is that new clean hydrogen economics could pave new pathways for renewable providers. The enactment of the Inflation Reduction Act in 2022 has ignited interest in green hydrogen. While lack of infrastructure makes hydrogen production unfeasible, policies driven by the Act could open doors for renewable energy companies like NextEra Energy Inc. (NYSE:NEE), General Electric Co. (NYSE:GE), and Plug Power Inc. (NASDAQ:PLUG) to benefit in 2023, causing investors to flock towards these stocks.
Lastly, an important sign that the renewable energy sector is maturing as an industry is that it is increasingly entering the scopes of different cyber attacks. With cyber threats projected to rise significantly in 2023, it is a good indicator that the clean energy transition is progressing, especially in countries with the cleanest air in the world.

Our Methodology
To compile our list of the 30 countries with the cleanest air in the world, we looked at the IQAir's World Air Quality Report, which ranks countries based on their AQI (Air Quality Index) as of 2022. The AQI takes into account pollutants such as PM2.5 (particulate matter with a diameter of 2.5 micrometers or less), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3) concentration levels. The higher the AQI value in a country, the greater the level of overall air pollution. For instance, an AQI value of 30 or below represents good air quality while an AQI value north of 300 represents hazardous air quality. We also looked at the Environment Protection Index by Yale University and the Global Green Economy Index (GGEI) to examine annual trends in air quality. We did this to account for seasonal variations, fluctuations and to validate our results. Subsequently, we selected 30 countries with the lowest AQI and ranked them from highest to lowest.
