We are currently changing. In the next few years we could change the way we live and in this way slow down climate change and its effects. But how expensive is the conversion to a sustainable infrastructure? Researchers from the United States took a closer look at this.
The basis is the current climate targets. According to these, the country should become completely climate neutral by 2050. This is also necessary to keep global warming below 1.5 degrees Celsius. The results are amazing if the cost were only $ 1 per person per day.
Concrete measures that have to be implemented include the following points: Increase in solar and wind capacities to 500 gigawatts (by 3.5 times), increasing the number of electric vehicles on the roads and building sustainable buildings. This also means that dirty energy sources must be phased out as soon as possible.
Depending on the scenario, this would result in costs of 0.2 percent to 1.2 percent of the gross domestic product. Compared to five years ago, the costs are significantly lower, also because prices for solar systems and batteries have fallen significantly.
Every citizen is in demand at the turnaround . If, for example, new purchases are made, the sustainability of a product should become a purchase argument. Americans could also benefit from new jobs if energy sources were used locally and no longer imported from abroad.
The initial costs for a sustainable infrastructure are likely to continue to fall. Even if we compare these with the costs that arise from climate damage. Droughts, hurricanes and other natural disasters increase year after year, and if you invest the “lost” money in the future today, you can probably avoid a lot of suffering. Ultimately, however, each country has to decide for itself which course it will take in the future.
