The reason why oil is so scarce now is because fossil fuels (oil) are not sustainable. Fossil fuels are also in very high demand, Which is making it run out even quicker.
But eventually, fossil fuels (oil) WILL run out. And companies will have to find another energy source. One option could be solar panels, which are reusable and sustainable.
Over the course of a few years, more and more companies start to use solar panels as their new environmentally-friendly energy source. This is why: Solar energy is a non-polluting source of energy and it does not create any greenhouse gases when producing electricity.
