3% of global electricity is generated from Oil

Oil, a dense, carbon-rich substance derived from ancient organic materials, has served as a cornerstone of human energy consumption for decades. It is sourced primarily through drilling techniques that tap into underground reservoirs, making it a prominent player in the global energy landscape. Oil's versatility allows it to power vehicles, heat homes, and generate electricity. Despite its historical significance, the reliance on oil is increasingly questioned due to environmental concerns and the urgent need for transition toward sustainable energy sources.

When used for electricity generation, oil is typically burned in power plants to produce heat. This heat then boils water, creating steam that drives turbines connected to electricity generators. While simple and efficient, this process results in significant carbon emissions, contributing to the environmental footprint of oil-fired power generation. Although oil once played a greater role in electricity production, its use has been declining as cleaner alternatives gain prevalence.

One of the primary disadvantages of using oil for electricity is its high carbon intensity. At 650 gCO2eq/kWh, oil emits significantly more carbon dioxide per unit of electricity generated compared to low-carbon alternatives. For instance, wind power has a carbon intensity of only 11 gCO2eq/kWh, while solar stands at 45 gCO2eq/kWh and nuclear at 12 gCO2eq/kWh. These low-carbon energy sources not only offer cleaner electricity but are critical in combating climate change, highlighting the need for a shift away from fossil fuels like oil in the electricity mix.

In addition to its carbon footprint, oil combustion contributes to air pollution, which poses significant public health risks. Burning oil releases a variety of pollutants, including sulfur dioxide, nitrogen oxides, and particulate matter, which can adversely affect air quality. These emissions are linked to respiratory diseases, cardiovascular problems, and premature mortality. The transition to low-carbon electricity sources like solar, nuclear, and wind presents an opportunity to reduce reliance on oil and subsequently mitigate its environmental and health impacts.

The pressing need to decarbonize and our drive for a clean energy future necessitate an ambitious expansion of clean electricity sources. Embracing the consistent and scalable output of nuclear power alongside the abundant potential of solar arrays will ensure that we meet the rising energy demands driven by electrification and technological advancements like AI. This transition not only supports environmental health but also propels us toward a sustainable and resilient energy landscape.
