Rising Energy Prices are Good for Renewable Energy

German energy giant RWE has issued a warning: energy prices are going to rise significantly over the coming years. Network maintenance, new power plant construction, and the costs of the energy transition are all being cited as reasons for the increases.

The Silver Lining

This is bad news for consumers in the short term. But it has a silver lining for renewable energy — and here is why.

The business case for renewable energy always comes down to economics. Solar panels, wind turbines, and electric motors require upfront investment. The payback period depends on how much you would otherwise spend on conventional energy. When energy prices rise, the payback period shortens. Renewable investments become more attractive.

For Boating Specifically

For boating, this is particularly relevant. A diesel boat burns fuel every time you use it. An electric boat charged from solar panels or grid electricity has much lower running costs — and if electricity prices rise more slowly than diesel prices (which historically they tend to), the advantage grows over time.

I have run the numbers for my own situation. Even with the current price differential, an electric motor conversion pays back its cost within a reasonable number of years of typical use. With rising diesel prices, that calculation gets better every year.

The Tipping Point

We are approaching a tipping point where choosing electric is not just the environmentally responsible choice — it is also the economically rational choice. Rising energy prices accelerate that process.

The smart boat owner is thinking about this now. The longer you wait to convert, the more you spend on diesel in the meantime.

RWE's Warning

Interestingly, it is one of Europe's largest conventional energy companies making this warning. They are not doing it to promote renewables — they are doing it to justify their own investment plans. But the effect is the same: a clearer signal that the era of cheap fossil fuels is over.

The future is renewable. And the economics are increasingly pointing in the same direction.
