Write a conclusion on coal and petroleum in 100 to 50 word

Coal and petroleum are valuable natural resources, providing a significant source of energy for many industries and households. However, their extraction and use have considerable environmental impacts, including air pollution and climate change. Furthermore, they are non-renewable, meaning their supplies are finite and will eventually deplete. Therefore, while coal and petroleum have played a crucial role in our development, it is essential to transition towards more sustainable and renewable energy sources for our future.
