For years, we’ve been told that renewable energy is the future, and that it’s only a matter of time before it becomes the dominant source of power worldwide. And it’s true – renewable energy has made tremendous progress in recent years, with costs plummeting and efficiency increasing. But here’s the thing: despite all the hype, renewable energy might actually be more expensive than traditional fossil fuels in many cases. And that’s a problem.

Let’s face it – the cost of renewable energy has been driven down by government subsidies and tax credits, which have artificially lowered the cost of production. But what happens when those subsidies disappear? And what about the actual cost of building and maintaining a renewable energy infrastructure? It turns out that the numbers are not as rosy as they seem.
Take solar power, for example. While the cost of solar panels has indeed decreased dramatically over the years, the cost of building a solar farm is still much higher than a traditional coal or gas plant. According to a study by the National Renewable Energy Laboratory (NREL), the average cost of building a solar farm in the US is around $2.5 million per megawatt, compared to around $1.2 million per megawatt for a traditional fossil fuel plant.

And don’t even get me started on energy storage. While batteries have made huge strides in recent years, the cost of storing energy for long periods of time is still prohibitively expensive. According to a report by BloombergNEF, the cost of lithium-ion batteries, which are used in most renewable energy systems, has decreased by around 70% over the past decade – but they still cost around $200 per kilowatt-hour (kWh), compared to around $50 per kWh for traditional fossil fuels.
But what about wind power? Isn’t it the cheapest form of renewable energy? Well, not always. While wind power is indeed cheaper than solar in many cases, the cost of building and maintaining a wind farm is still relatively high. According to the American Wind Energy Association (AWEA), the average cost of building a wind farm in the US is around $3 million per megawatt, compared to around $2 million per megawatt for a traditional fossil fuel plant.
So what’s the big deal? Why does it matter if renewable energy is more expensive than traditional fossil fuels? Well, for one thing, it means that we’re not going to be able to transition to 100% renewable energy as quickly as we thought. The economics just don’t add up. And secondly, it means that we’re going to have to rely on government subsidies and tax credits to prop up the industry – which is not a sustainable long-term solution.
So what’s the solution? Well, for starters, we need to get creative with our energy storage solutions. We need to develop new technologies that can store energy for long periods of time at a lower cost. And we need to rethink our energy infrastructure – perhaps investing in microgrids and other decentralized energy systems that can be more efficient and less expensive.
In the end, the cost of renewable energy is not just a technical question – it’s a economic and policy question. We need to have a more nuanced conversation about the pros and cons of renewable energy, and not just assume that it’s the answer to all our energy needs.
