Chapter 1: The Urgency of Transitioning to Renewables

The winds of change are blowing, and they herald a pivotal moment for renewable energy. Despite our rapid descent into a climate crisis of our own making, the global reliance on fossil fuels continues unabated, leading to dire consequences. A prime example is Europe’s dependence on Russian natural gas, which not only contributes significantly to carbon emissions but also allows for geopolitical manipulation and energy insecurity. Historically, fossil fuels have been our go-to energy source due to the perceived high costs and unreliability of renewable options. However, emerging data suggests a shift is on the horizon.

A recent analysis by Rystad Energy explores the ongoing Russian gas crisis in Europe. It reveals that while wholesale gas prices currently hover around €134 per megawatt, projections suggest a drop to approximately €31 per MWh by 2030. This would result in a levelized cost of energy for gas power stations reaching €150 per MWh, a figure that is threefold higher than the present cost of solar energy at €48 per MWh. In fact, this would align gas prices with the notoriously high costs associated with nuclear power. Rystad's research indicates that for gas to compete effectively with solar energy, gas prices would need to plummet to €17 per MWh, and the cost of carbon capture would need to be around €10 per metric tonne—targets that seem implausible.

Consequently, Rystad concluded that maintaining gas power stations in the EU could ultimately be ten times more expensive than transitioning to solar farms today.

This transition, however, is not trivial. Gas constitutes 34% of Europe’s energy supply, equating to around 550 TWh annually. One might wonder how extensive a solar farm would need to be to offset this reliance.

To provide context, a 1 MW solar farm generates 0.0021 TWh per year and occupies 0.028 square kilometers. Calculating the requirements reveals that a solar installation capable of replacing this gas supply would need to cover approximately 733.3 square kilometers—an area comparable to twelve Manhattans or half of Greater London. Notably, this represents just 0.007% of Europe's total land area and would require a dispersed network of smaller solar farms, optimizing land use while facilitating site selection.

The financial outlay for such a project is estimated at around €260 billion, which may seem steep. However, the upfront costs of solar power are offset by predictable long-term profits. Divided among the EU population, this amounts to about €581.91 per person, or roughly €4.84 monthly over a decade—allowing for energy prices to potentially decline rather than increase.

In essence, transitioning from gas to solar could yield significant financial savings for the EU, all while curtailing carbon dioxide emissions by 9.9 million tonnes annually (considering gas emits 18g of CO2 per kWh).

While this scenario is centered on Europe, similar patterns are emerging globally, indicating a clear justification for phasing out fossil fuel power stations in favor of renewable sources, which promise lower costs.

However, the tipping point extends beyond just gas and solar. Coal pricing sits at around €108 per MWh, while wind energy is only €38 per MWh. This suggests that replacing existing gas and coal plants with solar and wind energy is more economically viable than continuing their operation.
