A new report from McKinsey & Company, the “Global Energy Perspective,” lays bare what many of us – dismissed as “climate deniers” – have been asserting all along: Coal, oil and natural gas will continue to be the dominant sources of global energy well past 2050.
The McKinsey outlook for 2025 sharply adjusts prior projections. Last year, the management consultant’s models had coal demand falling 40% by 2035. Today, McKinsey projects an uptick of 1% over the same period. The dramatic reversal is driven by record commissioning of coal-fired power plants in China, unexpected increases in global electricity use, and the lack of viable alternatives for industries like steel, chemicals and heavy manufacturing.
The report states that the three fossil fuels will still supply up to 55% of global energy in 2050, a forecast that looks low to me. Today’s share for hydrocarbons is about 64%.
In any case, McKinsey’s report confirms what seasoned energy analysts and pragmatic policymakers have long maintained: The energy transition will not be swift, simple, or governed solely by climate targets. In fact, this energy transition will not happen at all without large scale deployment of nuclear, geothermal or other technological innovations that prove practical.
In places such as India, Southeast Asia and sub-Saharan Africa, the top energy priorities are access, affordability and reliability, which together add up to national security. Planners are acutely aware of a trap: Sole reliance on weather-dependent power risks blackouts, industrial disruption, economic decline and civil unrest.
That is why many developing nations are embracing a dual track: continued investment in conventional generation (coal, gas, nuclear) while developing alternative technologies. McKinsey says this in consultancy lingo: “Countries and regions will follow distinct trajectories based on local economic conditions, resource endowment, and the realities facing particular industries.”
In countries like India, Indonesia and Nigeria, the scale of electrification and industrial expansion is enormous. These countries cannot afford to wait decades for perfect solutions. They need “reliable and good enough for now.” That means conventional fuels will be retained.
McKinsey’s analysis also underscores what physics and engineering dictate: Intermittent and weather-dependent sources, such as wind and solar, require vast land areas, backup batteries and generation and power-grid investments, none of which come cheaply nor quickly.
The technologies of wind and solar branded as renewable should instead be called economy killers. They make for expensive and unstable electrical systems that have brought energy-rich nations like Germany to their knees. After spending billions of dollars on unreliable wind turbines and solar panels and demolishing nuclear plants and coal plants, the country is struggling with high prices and economic stagnation.
The Germans now have a word for their self-inflicted crisis: Dunkelflaute. It means “dark doldrums”—a period of cold, sunless, windless days when their “green” grid fails. During a Dunkelflaute in November 2024, fossil fuels were called on to provide 70% of Germany’s electricity.
If “renewables” were truly capable, planners would shut down fossil fuel generation. But that is not the case. While wind and solar are pursued in some places, coal and natural gas remain much sought-after fuels. In the first half of 2025 alone, China commissioned about 21 gigawatts (GW) of new coal-fired capacity, which is more than any other country and the largest increase since 2016.
Further, China has approved construction of 25 GW of new coal plants in the first half of 2025. As of July, China’s mainland has nearly 1,200 coal plants, far outstripping the rest of the world.
McKinsey points to a dramatic surge in electricity demand driven by data centers, which is estimated to be about 17 % annually from 2022 to 2030 in the 38 OECD countries. This kind of growth in electricity use simply cannot be met by wind and solar.
When analysts, journalists and engineers point out these realities, they’re branded as “shills” for the fossil fuel industry. However, it is not public relations to point out the physics and economics that make up the math for meeting the world’s energy needs. Dismissing such facts is to deny that reliable energy remains the bedrock of modern civilization.
The cost of foolish “green” policies is being paid in lost jobs, ruined businesses, disrupted lives and impoverishment that could have been avoided by wiser choices.
For those who have repeated energy realities for years, the vindication is bittersweet. The satisfaction of being right is tempered by the knowledge that many have suffered because reality has been ignored.
