Currently, the global energy production is dominated by fossil fuels, mainly coal, oil, and natural gas. These non-renewable sources account for around 80% of the world’s energy consumption. The remaining 20% is primarily sourced from renewable energy, including hydropower, wind, solar, and biomass.
However, future predictions indicate a transition towards a more sustainable and renewable energy mix. Here are some expected changes in the global energy percentage by type:
1. Renewable Energy: The use of renewable energy sources is anticipated to grow significantly in the coming decades. Falling costs, advancements in technology, and increasing environmental concerns are driving this shift. It is projected that by 2050, renewables could make up around 50% or more of the global energy production.
2. Fossil Fuels: While the overall energy share of fossil fuels is expected to decline, they will likely still play a significant role in the global energy mix. However, as renewable energy becomes more accessible and affordable, the percentage of fossil fuel usage is likely to decrease to below 50% by 2050.
3. Natural Gas: Of the fossil fuel sources, natural gas might experience relatively steady or even rising demand in the future. It is considered a cleaner alternative to coal and oil, emitting fewer greenhouse gases. However, its long-term dominance will depend on various factors, including policy decisions and availability of alternative energy sources.
4. Coal: Coal, the most polluting fossil fuel, is projected to witness a significant decline in its share of global energy production. Environmental concerns over carbon emissions, air pollution, and the availability of cheaper renewable alternatives have positioned coal as a less favorable energy source. It is likely that coal will contribute to less than 10% of the global energy production by 2050.
5. Nuclear Energy: Nuclear power’s contribution to the global energy mix is expected to remain somewhat stable, although some countries may choose to phase out or reduce their reliance on it. Safety concerns, high initial costs, and waste management issues may limit the growth of nuclear energy, but it could still account for around 10% of global energy production by 2050.
It is important to note that these predictions are subject to change based on various factors, including policy decisions, technological advancements, and the rate of global energy consumption growth. However, it is clear that the world is moving towards a greater reliance on renewable energy sources in the future.
