Pros and Cons of Fossil Fuels: A Complete Guide

Fossil fuels still account for roughly 86 percent of the world’s primary energy supply^[1], which makes understanding the pros and cons of fossil fuels essential for any organisation thinking about its energy strategy. Coal, oil and natural gas power transport, industry and electricity grids, yet they also drive the bulk of energy-related carbon emissions. This guide examines the main advantages and disadvantages of fossil fuels, sets them against the fast-growing alternatives, and looks at what they mean for the audiovisual and events sector, where generators, transport and location power remain central concerns.

What fossil fuels are and why they still dominate

Fossil fuels are carbon-rich energy sources formed over millions of years from the remains of plants and organisms: coal, crude oil and natural gas. Despite the rapid rise of renewables, they continue to supply the large majority of global energy. Fossil fuels retained their dominant position at about 86 percent of global energy supply, with oil consumption reaching 103 million barrels per day and coal remaining the single largest source of electricity at roughly 32.6 percent of generation^[1]. Energy-related carbon dioxide emissions also rose to about 35.8 billion tonnes^[1]. Understanding why fossil fuels remain so entrenched is the first step in weighing their pros and cons fairly.

The advantages of fossil fuels

Several practical strengths explain the continued reliance on fossil fuels. The first is reliability and controllability: fossil fuel generation can be dispatched on demand and does not depend on weather conditions, unlike solar or wind output that fluctuates^[2]. The second is storage and transport: fossil fuels can be stored almost indefinitely and moved easily through pipelines or tankers, which allows supply to be built up ahead of peak-demand seasons^[2].

A third advantage is cost and infrastructure. Centuries of investment have produced an extensive, mature system of extraction, refining and distribution, which keeps fossil energy relatively affordable in many markets^[2]. Their high energy density also means a small volume of fuel delivers a large amount of usable energy, a major asset for heavy transport, aviation and industrial heat. These qualities are precisely why abrupt substitution is difficult and why a managed transition, rather than an overnight switch, is the realistic path for most organisations. For those mapping that path, a clear carbon footprint assessment provides the baseline needed to prioritise reductions.

The disadvantages of fossil fuels

The drawbacks of fossil fuels are increasingly decisive. The most significant is their climate impact: burning coal, oil and gas is the primary driver of energy-related carbon emissions, which continue to climb^[1]. Fossil fuels are widely regarded as the main contributors to global warming, with coal the most carbon-intensive of the three^[2].

A second disadvantage is air pollution and health damage. Combustion releases greenhouse gases alongside fine particles and harmful compounds that degrade air quality and threaten human health^[2]. A third is finite supply: as non-renewable resources, reserves face depletion on a human timescale at current consumption rates^[2]. Fossil fuels also carry safety and environmental hazards, from the flammability of natural gas to extraction accidents and oil spills that cause lasting ecological harm^[2]. Finally, exposure to price volatility leaves economies vulnerable to geopolitical shocks, a risk that measuring and reporting emissions through frameworks such as the GHG Protocol helps organisations anticipate and manage.

Pros and cons at a glance

The table below summarises the key trade-offs of fossil fuels across the dimensions that matter most for decision-making.

Fossil fuels and the energy transition

The balance of pros and cons is shifting as alternatives mature. Solar accounted for the majority of renewable growth and reached about 8.7 percent of total power generation, overtaking wind^[1]. Renewables now offer dispatchable options when paired with battery storage, eroding the reliability advantage that once favoured fossil fuels. The strategic question for most organisations is no longer whether to move away from fossil energy, but how quickly and in what sequence.

That shift is reshaping investment, procurement and reporting. A growing number of renewable energy providers compete directly on price and reliability, while regulation pushes companies to disclose their emissions and reduction plans. Building a credible roadmap starts with a clear green strategy and a firm grasp of where emissions actually come from, so that reductions target the highest-impact sources first rather than the most visible ones. The future of green technology suggests this trend will accelerate rather than reverse.

Fossil fuels in audiovisual production and events

The pros and cons of fossil fuels take a concrete shape on film sets and at live events, where energy is often needed in places the grid does not easily reach. Understanding where fossil fuel use concentrates is the starting point for reducing it without compromising a production.

Film and television production

On location, diesel generators have long powered lighting, camera and catering because they are reliable and portable, two classic fossil fuel advantages. The downside is significant local emissions and air pollution on set. Productions increasingly replace or supplement generators with grid tie-ins, battery power stations and cleaner fuels, and document the shift as part of sector frameworks such as Albert and Ecoprod. Transport of crew and equipment, still largely fuelled by diesel and petrol, usually represents one of the largest emission sources of a shoot, which makes it a priority target for any reduction plan built on a production management workflow.

Live events

Festivals and outdoor events face the same tension: temporary power on a remote site is often supplied by fossil-fuelled generators. Organisers reduce this footprint by connecting to the grid where possible, pooling generator capacity, switching to renewable fuels and planning audience and crew mobility around lower-carbon options. The reliability of fossil fuels remains a genuine operational argument, but the environmental and reputational costs push the sector steadily toward alternatives.

Conclusion

Weighing the pros and cons of fossil fuels shows a resource that is reliable, storable and deeply embedded in global infrastructure, yet responsible for most energy-related emissions, serious health impacts and growing price risk. With fossil fuels still supplying the large majority of world energy^[1], the realistic course for most organisations is a managed transition that keeps the operational strengths in view while steadily cutting the carbon and pollution costs. As renewables become cheaper and more dispatchable, and as reporting obligations tighten, the balance will keep tilting toward cleaner alternatives, including in energy-intensive creative sectors such as film, television and live events.
