Hemp as a fuel?

Biomass fuels are clean and virtually free from metals and sulfur, so they do not cause nearly as much air pollution as fossil fuels. Even more importantly, burning biomass fuels does not increase the total amount of carbon dioxide in the Earth’s atmosphere. When petroleum products are burned, carbon that has been stored underground for millions of years is added to the air; this may contribute to global warming through the “Greenhouse Effect”, which is a popular theory which says that certain gases will act like a wool blanket over the entire Earth, preventing heat from escaping into space. In order to make biomass fuels, this carbon dioxide has to be taken out of the air to begin with — when they are burned it is just being put back where it started.

Another advantage over fossil fuels is that biomass fuels can be made right here in the United States, instead of buying them from other countries. Instead of paying oil drillers, super-tanker captains, and soldiers to get our fuel to us, we could pay local farmers and delivery drivers instead. Of course, it is possible to chop down trees and use them as biomass. This would not be as beneficial to the environment as using hemp, especially since trees that are cut down for burning are “whole tree harvested.” This means the entire tree is ripped up and burned, not just the wood. Since most of the minerals which trees use are in the leaves, this practice could ruin the soil where the trees are grown. In several places in the United States, power companies are starting to do this — burning the trees in order to produce electricity, because that is cheaper than using coal. They should be using hemp, like researchers in Australia started doing a few years ago.
