As the world grapples with the existential threat of climate change, the notion that renewable energy is the cheaper and more sustainable alternative to fossil fuels has become a rallying cry for the environmental movement. Politicians, activists, and even some business leaders have touted the benefits of solar and wind power, claiming that they will soon be the dominant source of energy worldwide. But is this really the case?

A closer look at the numbers suggests that the cost of renewable energy is not as low as we’ve been led to believe. In fact, when you factor in the costs of infrastructure, maintenance, and intermittency, the economics of renewable energy are far more complex and nuanced than we’ve been told.
Let’s start with the cost of solar panels. While it’s true that the price of photovoltaic panels has declined dramatically over the past decade, the cost of installing them has increased significantly. According to a report by the International Renewable Energy Agency (IRENA), the levelized cost of solar energy – which takes into account the cost of installation, maintenance, and replacement – is actually higher than previously thought. In many parts of the world, the cost of installing solar panels can be as high as $2.50 per watt, which is more than double the cost of fossil fuels in some cases.
Wind energy is no exception. While wind turbines have become more efficient and cheaper to build, the cost of maintaining and repairing them is high. A study by the American Wind Energy Association found that the average cost of maintenance for a wind turbine is around $100,000 per year, which is a significant expense for an industry that relies heavily on economies of scale.
But the biggest challenge facing renewable energy is intermittency. Solar and wind power are not always available when we need them, which means that we need to have backup systems in place to ensure a stable supply of electricity. This can be achieved through energy storage technologies like batteries, but these are still in their infancy and are expensive. According to the National Renewable Energy Laboratory, the cost of energy storage is around $100 per kilowatt-hour, which is significantly higher than the cost of electricity from fossil fuels.
So, why is it that the cost of renewable energy is not as low as we’ve been told? One reason is that the economics of renewable energy are often skewed by subsidies and tax credits. Governments around the world offer generous incentives to renewable energy companies, which can make them appear more competitive than they actually are. But as these subsidies are phased out, the economics of renewable energy will come under increasing pressure.
Another reason is that the cost of renewable energy is often measured in terms of the cost of the energy itself, rather than the cost of the entire system. This ignores the costs of infrastructure, maintenance, and other expenses that are necessary to keep the lights on. In reality, the cost of renewable energy is often higher than we think, and it’s only by taking a more holistic view of the economics that we can get a true picture of its costs and benefits.
So what does this mean for the future of renewable energy? It means that we need to be more realistic about its costs and benefits, and we need to be more strategic about how we deploy it. Rather than relying on subsidies and tax credits, we need to develop more efficient and cost-effective technologies that can compete with fossil fuels on their own merits. We also need to invest in energy storage and other forms of infrastructure that can help to mitigate the intermittency of renewable energy.
Ultimately, the cost of renewable energy is not the only factor that determines its adoption. Politics, policy, and public opinion all play a role, and it’s only by taking a more nuanced and realistic view of the economics that we can create a sustainable and equitable energy future for all.
