Another challenge is the cost of renewable energy technologies and infrastructure, which may be higher than fossil fuels in some cases. However, many studies have shown that the benefits of renewable energy outweigh the costs in the long term, as they reduce greenhouse gas emissions, air pollution, health impacts, and dependence on imported fuels. Moreover, renewable energy can create more jobs and stimulate economic growth.
The main obstacle and actually the first step that must be taken is this which is very difficult. Namely infrastructure development which is quite expensive and requires quite prolonged development until finally everything is ready in every area from big cities to remote areas. But actually the expensive financing is also equivalent to financing fossil fuel infrastructure too. Imagine if we started from a primitive state and started to discover fossil energy and we built the infrastructure. Of course, even then everything will feel very expensive. But still, all this was done slowly so that in the end development was evenly distributed in all regions and everyone began to use and get the benefits. So the development of renewable energy infrastructure will be the same. Yes, the costs will seem expensive, but when development continues slowly and gradually, without realizing it, all the infrastructure will be spread out and ready to be used.
The point is that all development will definitely be very expensive.
But because of the urgent need, everything will still be built, even if it has to be done little by little. Moreover, currently we are truly witnessing the destruction of nature. Where the climate is becoming hot due to global warming. So all countries are required to adopt renewable energy structurally and slowly. step by step. And ultimately everyone who currently even rejects renewable energy will eventually accept it and use it if the infrastructure is in place.
The point is that everything will ultimately use renewable energy. But it may take years or even decades to completely switch to renewable energy. But fossil energy will probably still exist and will only be used in limited portions.
