Fossil fuels still account for over 80% of global energy production
Fossil fuels remain the dominant source of global energy production, accounting for more than 80% of the world's energy. This heavy reliance on fossil fuels has severe consequences for the planet. Fossil fuels, such as coal, oil and gas, are the primary contributors to global climate change, responsible for over 75% of greenhouse gas emissions and nearly 90% of carbon dioxide emissions. The burning of these fuels releases harmful by-products, including air pollution, which has adverse effects on human health and the environment.
Despite the urgent need to reduce emissions, fossil fuels continue to be utilised globally due to their accessibility and the lack of efficient alternatives. About 80% of the global population resides in countries that are net importers of fossil fuels, making them vulnerable to geopolitical shocks. However, this also presents an opportunity for renewable energy sources, which are available in all countries and can provide energy security and independence.
Renewable energy sources, such as wind, solar, water, waste and geothermal heat, offer a cleaner and more sustainable alternative. They emit little to no greenhouse gases, are readily available and, in most cases, are cheaper than fossil fuels. The cost of renewable energy technologies has been decreasing rapidly, with prices for solar power falling by 85% between 2010 and 2020, and wind energy costs dropping by 56% (onshore) and 48% (offshore). This makes renewable energy more attractive, especially to low- and middle-income countries, and it is projected that renewable energy will continue to get cheaper over time.
While renewable energy sources are gaining ground, they currently meet only about 29% of global electricity needs. The main challenge with renewable energy is the need for reliable baseload power. Solar and wind energy, for example, are intermittent sources that depend on weather conditions. As a result, utilities employing solar and wind farms must still rely on fossil-fuelled generators to provide power when the sun isn't shining or the wind isn't blowing. However, this challenge may be overcome with the development of efficient and economical energy storage technologies, which could enable a more sustainable and resilient energy system.

Renewable energy sources emit less CO2 than fossil fuels
Renewable energy sources, such as wind, solar, and hydropower, emit little to no greenhouse gases and are readily available. About 29% of electricity currently comes from renewable sources, and this percentage is expected to continue growing. The cost of renewable energy has also been decreasing, with solar power prices falling by 85% between 2010 and 2020, and wind energy costs dropping by 56% (onshore) and 48% (offshore). This makes renewable energy more attractive, especially to low- and middle-income countries, and it is projected to get even cheaper over time.
The transition to renewable energy has multiple benefits. Firstly, it reduces import dependency, allowing countries to diversify their economies and protect themselves from the unpredictable price swings of fossil fuels. Secondly, it creates more jobs. For example, the IEA estimates that the transition to net-zero emissions will result in a net gain of 9 million jobs in the clean energy sector by 2030. Finally, renewable energy sources are safer and healthier for the population. Fossil fuel pollution causes approximately 8 million deaths each year, whereas renewable energy sources produce little to no air pollution, which has adverse effects on lung health.
While nuclear energy has been proposed as a solution to replace fossil fuels, it has its drawbacks. Although it is reliable, clean, safe, and cheap, nuclear energy is not renewable and has caused notable accidents, such as Chernobyl, which resulted in fatalities.
In conclusion, renewable energy sources emit less CO2 than fossil fuels and offer a cleaner, safer, and more sustainable alternative. With the cost of renewable energy decreasing and the demand increasing, the transition to renewable energy is crucial to mitigating climate change and creating a healthier planet for future generations.

Fossil fuels are the largest contributor to global climate change
Fossil fuels, such as coal, oil, and gas, are the largest contributor to global climate change. They account for over 75% of global greenhouse gas emissions and nearly 90% of all carbon dioxide emissions. The burning of fossil fuels to generate electricity and heat is a significant source of these emissions, contributing to the warming of the Earth and the rise in oceanic water levels.
While renewable energy sources like wind, solar, and hydropower are gaining traction, fossil fuels still dominate the global energy landscape, accounting for more than 80% of energy production. In the United States, despite the rapid growth of solar and wind power, they accounted for under 4% of total energy use in 2018. Fossil fuels like crude oil and natural gas have seen dramatic increases in production due to new technologies such as fracking and horizontal drilling.
The transition to renewable energy is crucial to mitigating climate change. Renewable sources emit little to no greenhouse gases, are readily available, and are often cheaper than fossil fuels. The cost of renewable energy has been decreasing, with solar power prices dropping by 80-85% in the past decade. This makes renewable energy more accessible and attractive, especially to low- and middle-income countries.
However, one challenge with renewable energy is the need for backup power sources when conditions are not favourable, such as a lack of wind or sunlight. Additionally, the manufacturing and installation of renewable energy infrastructure, like solar panels, can have environmental and safety impacts. Nevertheless, the overall environmental impact of renewable energy is significantly lower than that of fossil fuels.
To summarize, fossil fuels are the primary driver of global climate change due to their high greenhouse gas emissions. The transition to renewable energy sources is essential to combat this issue, and renewable energy offers environmental, economic, and social benefits. While challenges remain, the increasing demand and decreasing costs of renewable energy provide a promising path towards a more sustainable future.

Fossil fuels are unpredictable in price, whereas renewable energy is getting cheaper
Fossil fuels, such as coal, oil, and natural gas, have been the predominant source of global energy production for decades. However, the market for fossil fuels is notoriously unpredictable, with volatile price swings that can significantly impact consumers and businesses. For instance, oil prices might be at an all-time low, as they are currently in the UK, but this can quickly change, making heating costs volatile and unpredictable for homeowners and businesses alike.
The unpredictable nature of fossil fuel prices is primarily due to the finite supply of these resources and the growing global demand. As sources of fossil fuels become increasingly strained, prices are driven higher. For example, the United States is projected to spend approximately $360 billion more per year on fossil fuels by 2030 compared to 2006, with expenditures potentially surpassing $30 trillion between 2010 and 2030 if prices continue to rise. This unpredictability and volatility in pricing make long-term financial planning challenging for individuals, businesses, and governments reliant on fossil fuels.
In contrast, renewable energy sources, such as wind, solar, and hydropower, offer stable and predictable pricing. The cost of renewable energy technologies has been decreasing rapidly due to technological advancements and increasing global adoption. For example, the cost of electricity from solar power decreased by 85% between 2010 and 2020, while the prices of onshore and offshore wind energy fell by 56% and 48%, respectively. This trend is expected to continue, making renewable energy even more affordable in the future.
The stable and decreasing prices of renewable energy are not solely due to technological advancements but also to the inherent nature of these energy sources. Renewable energy sources are abundant and replenished naturally, making them less susceptible to the supply and demand fluctuations that drive fossil fuel prices. Additionally, the transition to renewable energy can reduce energy costs for consumers. A study by Professor Geoffrey Heal of Columbia Business School found that renewable electricity is less costly than electricity generated from fossil fuels. The study also highlighted that utility companies often price electricity above its marginal cost, whereas renewable energy sources can provide electricity at a lower cost.
