This study explores the relationship between health financing, environmental quality, and the quality of life in Nigeria. The Bayer and Hanck cointegration test affirms cointegration. Findings further reveal that CO2 emissions have no meaningful impact on life expectancy in the short run. In the long run, urbanization significantly deteriorates the quality of life. Also, public health expenditure has not contributed meaningfully to the quality of life. The study discovers no evidence of a feedback causality, but a one‐way causality flowing from urbanization to CO2 emissions. Policies that can enhance a sustainable environment and improve the quality of life are discussed.

“…This suggests that increasing electricity generation and distribution will improve production, which will in turn trigger growth. Renewable energy sources could be the game changer in this regard especially due to the ubiquitous campaign for clean energy (Alola, Alola, & Saint Akadiri, 2019; Alola, Yalçiner, & Alola, 2019; Alola & Yildirim, 2019; Balsalobre‐Lorente, Shahbaz, Roubaud, & Farhani, 2018; Bekun, Emir, & Sarkodie, 2019; Nathaniel, 2019; Nathaniel et al, 2019; Nathaniel & Iheonu, 2019). Renewable energy could be a solution to the country's energy poverty (Nathaniel, Anyanwu, & Shah, 2020; Nathaniel & Bekun, 2019).…”

Electricity consumption, urbanization, and economic growth in Nigeria: New insights from combined cointegration amidst structural breaks

The study explores the link between electricity consumption, urbanization, and economic growth in Nigeria from 1971 to 2014. The bounds test and the Bayer and Hanck (Journal of Time Series Analysis, 2013, 34(1), 83–95) cointegration tests affirm cointegrating relationship. Electricity consumption increases economic growth in both time periods, while the impact of urbanization appears to inhibit growth. The fully modified OLS, dynamic OLS, and the canonical cointegrating regression confirm the robustness of the findings. The vector error correction model Granger causality test supports the neutrality hypothesis in the short run and the feedback hypothesis among the variables in the long run. Therefore, policies to ensure efficient electricity supply, curb rapid urbanization, and promote sustainable economic growth were suggested.

“…Africa's energy mix is largely nonrenewable. Nonrenewable energy increases emissions thereby reducing environmental quality (Balsalobre‐Lorente, Driha, Bekun, & Osundina, 2019; Bekun, Emir, & Sarkodie, 2019; Nathaniel, 2019; Nathaniel & Iheonu, 2019). Therefore, for environmental sustainability, which is in line with the SDG 7, there is a need for the adoption of renewable energy sources like tidal power, biogas, geothermal, solar, wave power, and so forth.…”

This study explores the interrelationship between CO2 emissions and economic growth in selected Africa economies from 1990 to 2014 providing evidence from both static and dynamic models. Results show that increases in energy use have a significant and positive effect on economic growth; which goes to show that growth in Africa is actually energy dependent. Further findings suggest that CO2 emissions have no significant contemporaneous effect, however, a significant and negative effect at a one‐period lag on economic growth. The significance of the impacts is consistently confirmed by both the static and dynamic estimations. Also, trade adds to economic growth and also contributes to environmental deterioration in Africa. There is a dire need for Africa to adjust its energy portfolio by shifting to clean energy sources which will enhance sustainable economic growth without deteriorating the environment.
