Why does renewable investment surpassing fossil investment feel like a turning point, but isn't one yet?
The headline number is real and impressive: in 2022, global clean energy investment reached $1.6 trillion, exceeding fossil fuel investment by 61% [1]. That same year, renewable energy accounted for 90% of the growth in electricity capacity [1]. These figures suggest momentum is shifting. But the same report shows that fossil fuel investment still grew by 10% in 2022, reaching over $1 trillion, and the world's 20 largest oil and gas companies allocated only 4% of their capital spending to renewables [1]. So while clean energy is winning new investment dollars, the fossil fuel industry is not shrinking—it is still expanding, just more slowly.
The financial system also tells a mixed story. Lending to green energy rose to $498 billion in 2021, approaching fossil fuel lending levels, but the 40 banks that lend most to fossil fuels collectively invested $489 billion annually in fossil fuels from 2017 to 2021, with 52% of those banks actually increasing their lending compared to 2010–2016 [1]. And 78% of countries assessed still provided net direct fossil fuel subsidies totaling $305 billion in 2020 [1]. Investment flows are a tug-of-war, not a clean break.
What concrete barriers could slow or reverse the transition, even with high investment?
Policy and fiscal structures can create hidden obstacles. A study of Indonesia's energy transition found a 'fiscal paradox': tax policies intended to support renewables actually raise their cost. High VAT rates, import duties, and complex administrative processes push the levelized cost of electricity (LCOE) for renewable projects to an average of $58 per MWh, while 57% of energy sector revenue goes to fossil fuel subsidies and only 4.5% to renewables [5]. This means that even when investors want to put money into clean energy, government policies can make it uncompetitive.
Another study using panel data from developing countries (2010–2023) found that while green finance can reduce carbon emissions and support economic growth, its effectiveness depends on strong environmental regulation. Without that, factors like trade liberalization, foreign direct investment, urbanization, and energy use can actually increase emissions [4]. Investment alone is not enough—it must be paired with consistent policy.
On the energy performance side, a 2024 study found that wind and solar photovoltaics actually deliver better net useful energy than fossil fuels when you account for the inefficiencies of burning fuel for heat or motion. Fossil fuels' useful-stage energy return on investment (EROI) is only about 3.5:1, compared to roughly 8.5:1 at the final stage, because much energy is wasted as heat [2]. Renewable electricity systems have higher EROIs even after accounting for intermittency [2]. So the technical case for replacement is strong—but technical superiority does not guarantee political or economic adoption.
Can investor attention and public sentiment lock in the transition?
Investor attention can boost clean energy stocks, but it is volatile. A study of the COVID-19 pandemic period found that clean energy firms saw improved returns due to increased investor attention, while fossil fuel firms did not [3]. This suggests that crises and green recovery plans can shift capital flows. However, the same study notes that the pandemic's negative impact hit fossil fuel firms harder than clean energy firms, meaning the advantage was partly relative [3]. Investor sentiment can reverse with economic downturns or policy changes.
The Lancet Countdown report emphasizes that health concerns are increasingly linked to climate action in public discourse—24% of climate change newspaper articles in 2022 mentioned health, and 95% of updated national climate plans now reference health [1]. This growing awareness could sustain political pressure for clean energy. But the same report warns that without confronting the economic interests of fossil fuel industries, the emphasis on health risks becoming 'healthwashing'—rhetoric without real action [1].

The 2023 report of the Lancet Countdown on health and climate change: the imperative for a health-centred response in a world facing irreversible harms.
In 2022, clean energy investment reached $1.6 trillion (61% above fossil fuel investment), yet fossil fuel investment still rose 10% to over $1 trillion, and oil and gas companies allocated only 4% of capital to renewables; fossil fuel subsidies and lending remain high.
Estimation of useful-stage energy returns on investment for fossil fuels and implications for renewable energy systems
Fossil fuels' useful-stage energy return on investment (EROI) is only about 3.5:1, much lower than the final-stage EROI of ~8.5:1; wind and solar PV have higher EROIs than the ~4.6:1 threshold needed to match fossil fuels' net useful energy, even with intermittency.

During the COVID-19 pandemic, clean energy firms saw improved returns due to increased investor attention, while fossil fuel firms did not, suggesting green recovery plans can shift capital flows.

Examining the Fiscal Paradox in The Cost of Taxation and Its Impact on Renewable Energy Transition in Indonesia
In Indonesia, tax policies (VAT, import duties, administrative costs) raise renewable LCOE to ~$58/MWh, while 57% of energy revenue goes to fossil fuel subsidies and only 4.5% to renewables, creating a fiscal paradox that undermines investment competitiveness.
