Solar energy is the cheapest electricity in history
The price of solar electricity has dropped significantly over the years, with the IEA reporting a 20-50% reduction in costs compared to previous estimates. This reduction in cost is attributed to advancements in solar technology, with more efficient solar panels that convert a higher percentage of sunlight into electricity, resulting in lower costs per watt generated. For instance, the average cost of solar panels has decreased from around $30 per watt in the early 1980s to less than $0.50 per watt today, a remarkable 98% reduction in cost over four decades.
The decline in solar energy costs has levelled the playing field with fossil fuels, which have traditionally been considered more affordable. In 2016, a major commercial solar installation bid an extremely competitive price of 0.029 per kWh, comparable to the cost of fossil fuel steam and small-scale natural gas.
The shift towards solar energy is also driven by its environmental benefits. Solar energy is a renewable source that doesn't release greenhouse gas emissions, unlike fossil fuels, which contribute to air pollution, climate change, and environmental degradation. The detrimental effects of fossil fuels on human health further emphasize the need for a transition to cleaner energy sources. It is estimated that between 1.1 million and 2.55 million people die annually from fossil fuels used for electricity production.
While the transition to solar energy involves addressing challenges related to energy storage, grid stability, and infrastructure changes, the economic and environmental advantages of solar power are significant. As solar technology continues to advance and costs decline, solar energy is expected to become even more accessible and widely adopted in the coming years.

Solar power is a much more optimal resource environmentally than fossil fuels
The case for solar power over fossil fuels is strengthened by the declining cost of solar energy. The price of solar power has dropped significantly since its early uses, and this trend is expected to continue. In 2021, the International Energy Agency declared solar power to be the "cheapest electricity in history", with costs projected to decrease further. This cost-effectiveness is driven by technological advancements, economies of scale, and increasing investments.
The environmental and economic advantages of solar power have led to a growing momentum away from fossil fuels. The Rocky Mountain Institute, a green-focused think tank, predicts that solar power capacity will increase by three to four times by 2030. This shift is already underway, with coal's market share dropping in 2023.
While the transition to solar power offers significant benefits, it is important to acknowledge the challenges. The energy industry's infrastructure, investments, and policies are currently skewed in favor of fossil fuels, creating inertia in the system. However, the decreasing costs of solar power and its environmental advantages are driving a global shift towards cleaner and more sustainable energy sources.

Fossil fuels are an old technology, while solar is new and improving
Solar energy is a rapidly improving technology that offers a cleaner and cheaper alternative to fossil fuels. Fossil fuels are a well-established, old technology that has changed very little over the years. In contrast, solar power is a relatively new technology that has already seen massive growth and cost reduction, and it is expected to continue improving and becoming more affordable.
The cost of solar power has decreased significantly over the last decade, with a 90% decline in the cost of solar power according to the American Council on Renewable Energy. This is due to several factors, including increasing scale, more subsidies, and lower operational costs. As more people invest in solar, it becomes cheaper, and this trend is expected to continue. The Rocky Mountain Institute predicts that the price of solar energy will drop by half by 2030, making it even more affordable.
On the other hand, fossil fuels have remained relatively stagnant in terms of cost and technology. Adjusted for inflation, fossil fuels cost about the same as they did 100 years ago. The price of solar energy, on the other hand, has dropped by a factor of 5,000 since 1958. This is because solar energy is a technology, not a fuel, and as such, it is constantly improving. Fossil fuels, on the other hand, have an innovation cap, and their value proposition peaked many decades ago.
The benefits of solar energy are significant. Solar energy reduces our dependency on harmful fossil fuels and helps fight climate change by reducing carbon emissions. It is a renewable resource that replenishes, reducing conflict, price volatility, and the risk of war. Solar energy is also a low-impact form of energy production with little long-term impact on its surroundings.
While solar energy is not yet universally accessible, the solar industry is working to overcome these challenges through advanced research and development. The potential for solar energy to replace fossil fuels and mitigate the impact of the energy sector on climate change is immense. As renewable energy technology continues to improve, the end of fossil fuels draws nearer.

The cost of solar power has declined by 90%
Solar energy is significantly cleaner than fossil fuels. Fossil fuels, such as coal, release carbon dioxide (CO2) into the atmosphere, contributing to climate change. Economists previously argued that transitioning to cleaner power sources like solar energy would be costly. However, recent studies have revealed that decarbonizing our energy use can lead to substantial cost savings globally.
The cost of solar power has declined dramatically, making it an increasingly attractive alternative to fossil fuels. According to the American Council on Renewable Energy, the cost of solar power has declined by 90% over the last decade. This significant drop in price is attributed to several factors, including increasing scale, more subsidies, and lower operational costs. As the demand for solar energy has grown, the cost has decreased further, following a "learning curve" known as Wright's Law.
The decreasing cost of solar power has made it a more economically viable option compared to fossil fuels. In 2010, a megawatt-hour of solar photovoltaic electricity generation cost $378 globally, without considering subsidies. By 2019, this cost had decreased to $68, becoming cheaper than nuclear, coal, and even onshore wind. The cost of solar photovoltaic power from solar panels experienced an even more substantial drop, plummeting from $359 per megawatt-hour in 2009 to $40 in 2019, an 89% decrease.
The declining cost of solar power has had a significant impact on the energy industry. Building new solar farms is now more affordable than constructing new coal plants, with solar electricity 177% cheaper than coal-based electricity. This shift is primarily driven by technological advancements, which have made solar technology more accessible and efficient. As a result, solar power has expanded its market share tremendously, while coal's share has been steadily declining.
The cost-effectiveness of solar power is expected to drive further growth in the industry. The Rocky Mountain Institute, a green-focused think tank, predicts that solar power capacity will triple or quadruple by 2030, while the price of solar energy is projected to drop by half, reaching as low as $20 per megawatt-hour. These trends indicate a promising future for solar energy, making it an increasingly competitive and sustainable alternative to fossil fuels.
