Renewable energies have not only begun to boom as a result of the Paris Agreement. But the steadily increasing demand continues to shift the limits of technology on an ongoing basis. Wind turbines are growing in size and the associated forces are becoming more extreme – nonetheless, they must operate with absolute reliability and a minimum of maintenance effort. Coatings and surface treatments significantly extend the service life of their components and thus the lifetime of the entire system.
With the Paris Agreement, the interest in renewable energies has increased worldwide, as has the associated global level of investment. The agreement that was adopted on 12 December 2015 at the UN Climate Change Conference in Paris provides for a limitation of global warming caused by human influences to significantly less than 2 °C as compared to preindustrial values. It took effect on 4 November 2016. As of May of 2017, a total of 145 nations had signed it and these countries together account for 82.95% of global emissions.
