The cost of electricity produced by wind and solar power has been a highly debated topic. While some sources claim that wind and solar power are cheaper than electricity produced by fossil fuels, others argue that the price of fossil fuels does not include the environmental damage caused by carbon emissions. The cost of wind and solar power has decreased significantly over the years, with wind energy costs declining by 70% and solar power by 90% in the last decade. However, the intermittent nature of wind and sunshine makes it challenging to rely solely on these sources for electricity, and the cost of storage is high. Additionally, the direct subsidies for the fossil fuel industry, estimated at over $20 billion per year in the US, make it challenging for renewable energy sources to compete economically. Nevertheless, the adoption of wind and solar power is increasing rapidly, and they are expected to account for a significant portion of electricity generation by 2030.

The cost of fossil fuel energy is stagnant or increasing, while renewable wind energy costs are decreasing
The cost of producing electricity from fossil fuels is stagnant or increasing, while the cost of wind energy is decreasing. This is due to several factors. Firstly, the long existence of fossil fuel technology means that any cost-saving innovations have already been realized and incorporated into new and existing generation plants. In contrast, wind energy is still in its relatively early stages of development, with room for increased efficiencies and technological advancements that can drive down costs.
Secondly, wind energy has benefited from increasing scale, more subsidies, and lower operational costs. The expansion of wind farms and turbines has led to economies of scale, reducing the overall cost of wind energy. Additionally, subsidies and tax credits have made wind energy more affordable for consumers, leading to increased demand and revenue for manufacturers, who can then reinvest in improving their technology and processes, further driving down costs.
Moreover, wind energy has the advantage of not requiring costly fuel sources like coal, oil, or natural gas. The sun and the wind are free, natural resources, whereas fossil fuels must be obtained from the earth at a significant expense. This makes wind energy inherently less costly to produce than fossil fuels.
However, it is important to consider the reliability factor when comparing the costs of wind energy and fossil fuels. Fossil fuels can provide a consistent and reliable source of electricity, whereas wind energy is intermittent and unpredictable. To ensure a reliable electricity supply with wind energy, significant investments must be made in backup power sources and storage solutions, which can increase overall costs.
Despite this challenge, the cost of wind energy has been decreasing, and it is expected to become even more affordable in the future. According to the National Renewable Energy Laboratory (NREL), wind and solar installations in the US are projected to account for a significantly larger share of total electricity generation by 2030, further driving down costs.

Fossil fuels are heavily subsidised, whereas wind energy receives fewer subsidies
Fossil fuels are heavily subsidised by governments, with global subsidies reaching $7 trillion in 2022, a $2 trillion increase since 2020. These subsidies are intended to protect consumers by keeping prices low, but they have significant negative consequences. They lead to higher taxes or government borrowing, inefficient allocation of resources, and encourage pollution and climate change. Fossil fuel subsidies do not benefit the poor, but rather, mostly benefit higher-income households.
The subsidies come in the form of explicit and implicit subsidies. Explicit subsidies occur when the retail price of fuel is below its supply cost, and they are found in regions such as the Middle East, North Africa, Europe, and East Asia. Explicit subsidies made up 18% of the total fossil fuel subsidies in 2022. On the other hand, implicit subsidies, which made up 82% of the total, occur when environmental costs, local air pollution costs, and climate damage costs are not reflected in the pricing of fossil fuels.
The large amount of subsidies that fossil fuels receive creates an economic barrier for the wider adoption of renewable energy sources, such as wind energy. Wind energy receives fewer subsidies compared to fossil fuels. Renewable energy sources do not need subsidies to compete with fossil fuels when building new power plants. In fact, wind energy has become more cost-competitive with fossil fuels. The cost of wind energy has decreased due to technological advancements, such as increased turbine hub height and rotor diameter, as well as improved turbine technologies that increase energy output per turbine.
While wind energy has made significant strides in cost-competitiveness, there are still challenges. The inherent unreliability of wind and solar energy sources means that, to deliver reliable electricity, they often need to be supplemented by a reliable life-support grid, such as gas plants, which can be costly. Additionally, wind and solar energy are not suitable for all applications, such as long-distance transport or high-heat industrial processes, where fossil fuels remain the most viable option.

Fossil fuels are more reliable than wind energy, which is intermittent
While wind energy is a renewable source of energy with near-zero emissions, fossil fuels are often considered more reliable. This is because wind energy is intermittent and dependent on the wind, an unpredictable natural resource.
The reliability of electricity is paramount, and wind energy is often unreliable due to its dependence on weather conditions. To ensure a reliable electricity supply, backup power sources are needed to support wind energy, which adds to the overall cost. In contrast, fossil fuels can provide a more consistent and reliable source of energy without the same level of backup power requirements. This makes fossil fuels more attractive in terms of reliability, especially for meeting short-term rises in electricity demand.
However, it is important to note that the cost of fossil fuel energy is stagnant or increasing due to rising fuel costs. On the other hand, wind energy costs have been decreasing due to innovations in turbine design and technology advancements, making wind energy more price-competitive. Additionally, wind energy offers stable revenue streams and predictable returns on investment, making it an attractive option for investors.
The intermittency of wind energy can be mitigated by combining it with other renewable energy sources, energy storage solutions, and grid diversification. However, critics argue that wind energy is not sustainable when balanced by fossil fuel generators, as it still relies on fossil fuels for backup power.
In conclusion, while wind energy costs have become more competitive and offer stable investment opportunities, fossil fuels are currently considered more reliable due to the intermittent nature of wind energy. However, with increasing climate change impacts and the urgency to reduce emissions, wind energy is still an attractive option for businesses and governments seeking stable and profitable power solutions.

Fossil fuels are required for transportation, industrial heat, and residential heat
The cost of electricity produced by fossil fuels and wind energy has been a subject of debate, with some arguing that wind energy is cheaper. However, the role of fossil fuels in transportation, industrial heat, and residential heat is significant and cannot be overlooked.
Fossil fuels, such as coal, oil, and gas, have been the dominant energy source for transportation for centuries. In 2023, about 30% of total US energy consumption was dedicated to transporting people and goods. Petroleum products, including gasoline and diesel, accounted for about 89% of the US transportation sector's energy use. Gasoline is the dominant transportation fuel, used in cars, motorcycles, light trucks, boats, and airplanes. While biofuels and natural gas are also used, they account for a much smaller percentage.
For industrial heat, fossil fuels are burned to generate energy for various industrial processes. This includes providing the high levels of heat required for steel-making and other chemical reactions necessary to produce goods from raw materials. Industrial activities that burn fossil fuels are a significant source of greenhouse gas emissions, contributing to climate change and local air pollution.
Residential heat also relies on fossil fuels, particularly in commercial and residential buildings. Fossil fuels, such as natural gas, are burned to provide heat and are used in refrigeration and cooling systems. This contributes to greenhouse gas emissions, which have increased in recent years due to the rebound in economic activity after the COVID-19 pandemic.
While wind and solar energy are portrayed as cheaper alternatives to fossil fuels, their applicability in the transportation, industrial heat, and residential heat sectors is limited. For example, in the case of airplanes and cargo ships, solar and wind energy are not just more expensive but also incapable of providing the required energy for long-distance transport.
In conclusion, while the discussion around the cost of electricity produced by fossil fuels and wind energy is ongoing, it is important to recognize that fossil fuels remain essential for transportation, industrial heat, and residential heat due to their energy density, cost-effectiveness, and ability to meet current energy demands in these sectors.

Fossil fuel plants could generate more power to meet short-term rises in electricity demand
The cost of fossil fuel energy is stagnant, if not rising, due to increasing fuel costs. In contrast, renewable wind and solar energy prices are decreasing as the industry innovates and becomes more efficient. Despite this, fossil fuels are still cheaper than wind and solar energy in certain contexts.
For instance, Lazard's annual report on electricity generation costs found that onshore wind projects have an LCOE ranging from $37 per megawatt-hour to $86 per MWh, while utility-scale solar projects range from $38 to $78 per MWh. On the other hand, existing gas plants have a lower cost range of $24 to $39 per MWh, and even existing coal plants can be competitive, with a range of $31 to $114 per MWh. Thus, existing fossil fuel plants could generate more power to meet short-term rises in electricity demand.
However, it is important to note that the Lazard report has been criticized for not considering the cost of providing backup power to wind, solar, and short-duration storage batteries. When these costs are included, the price of wind and solar energy ranges from $71 per MWh for unsubsidized wind to $164 for solar-plus-storage.
Additionally, the argument that wind and solar are cheaper than fossil fuels is based on a comparison of the cost of unreliable renewable energy with reliable fossil fuel electricity. In reality, wind and solar energy are inherently unreliable, and to use them to deliver reliable electricity, we need to also pay for a reliable life-support grid, which can be costly.
Furthermore, there are many machines and industries that rely on the direct burning of fossil fuels and for which there are no realistic electric alternatives. For example, in transportation, oil is essential for powering airplanes and cargo ships, and in the heat industry, fossil fuels are often the only cost-effective option for reaching the high temperatures required.
In conclusion, while renewable energy prices are becoming more competitive and can help meet rising electricity demand, fossil fuels still have a role in meeting short-term rises in electricity demand due to their lower costs in certain contexts and their ability to power certain industries and machines that renewables cannot.
