Fossil fuels provide roughly 80% of the energy required to power our modern world. But as the old saying goes, all good things must come to an end. Coal, gas, and oil have a limited supply. Due to the increasing demand for energy worldwide, supplies are predicted to run out within the next half-century. Along with this, the mining, drilling, and burning of fossil fuels are harming the environment — and our health. We must embrace a clean energy future and find sustainable fuel sources to solve the fuel problem. Research suggests that biofuel, more specifically, hemp biofuel, could be the answer.
