Fossil fuels will run out one day, so we need to consider alternative options. However, we need to discuss their advantages and disadvantages. One of the most significant benefits of green energy is that they never run out with the sun always shining, the wind constantly blowing, and the Earth generating geothermal energy; we shouldn’t run out of power. Using fossil fuels emits greenhouse gases and toxins, which contribute to respiratory illnesses and global warming, so their environmental advantages to us are undeniable. The inability of alternative energies to be shipped quickly is a significant drawback. Furthermore, renewable energies are not always available as renewable energy, e.g., wind power may not blow one day but not the next; owing to the high initial cost, they will likely be unsustainable for decades. But, hopefully, the planet will be ready to use just green energies when fossil fuels run out.
