It is unrealistic to expect the world to 100% run on renewable energy. The infrastructure required for a complete transition is expensive and time consuming to implement. Renewable energy sources like solar & wind are intermittent & dependent on weather conditions which leads to fluctuations in supply. The storage & distribution of renewable energy on a large scale pose significant challenges. Some industries & regions heavily rely on non renewable sources like fossil fuels for their energy needs. Achieving a 100% renewable energy world would require substantial technological advancements, policy changes & global cooperation.
I think it is difficult to advance renewable energy at the moment, by encouraging its development it is hoped that management will be more independent, but the target will be difficult to achieve because it requires good technological progress
and it has been tested because the energy needs of users are now increasing, because in the development of renewable energy there are many obstacles faced such as limited infrastructure and limited technical expertise, because things like that require careful consideration but over time has changed this little by little but I believe In the future, all of this will definitely come true, even though it will take time to achieve all of that.
