In this study, researchers looked at how carbon taxes and reducing subsidies for fossil fuels affect the use of renewable energy in certain advanced countries. They found that taxing carbon emissions positively influences the adoption of renewable energy sources. By analyzing data from 2004 to 2014 in key OECD countries, they discovered that increasing carbon taxes led to a quick and significant rise in the use of renewable energies. This suggests that implementing carbon taxes can help shift towards cleaner energy options and lessen environmental impacts.
