In conclusion, it is possible for the world to be 100% dependent on renewable energy, but it would require a significant transformation of the current energy system and a collective effort from all stakeholders. Some countries and regions have already achieved or are close to achieving this goal, such as Iceland, Brazil, New Zealand’s South Island, Denmark’s Samsø island, and Germany’s Mecklenburg-Vorpommern and Schleswig-Holstein regions. These examples show that 100% renewable energy is not only feasible but also desirable for a sustainable future.
What impact will occur when the whole world tries to develop renewable energy and will this be a solution to the current extreme global warming problem? We are not one of the experts who can accurately review the impact of renewable energy, but what we know is that when this is done, there will be sectors that will start to be neglected and the way to develop may have to sacrifice other things. Dependence on nature may be an obstacle because unpredictable extreme weather occurs at any time and the costs required are also quite high to develop renewable energy so not all countries do it.
There must be an in-depth study when renewable energy begins to be developed and perhaps we also have to look at human ability to utilize it. If not, the development of renewable energy will only be enjoyed by a few people who have the ability to enjoy it and small communities will find it difficult to enjoy it if they are charged with having to pay for it.
