Ever since it was discovered, oil was hailed as black gold. Investors found it to be profitable, as the price per barrel of oil has continued to rise over the years.
The problem is that oil’s price continues to rise, which may make it a bad investment after a certain point. Smart investors are looking to invest in the six renewable types of gold:
Bioethanol represents one of the most accessible replacements for gasoline. It can be produced from any crop that produces starch or sugar through the fermentation process.
This fuel is already used in its pure form by government vehicles and corporations looking to use a more Earth-friendly source of fuel.
Biodiesel is another renewable fuel that can be produced from vegetables. It can also be derived from excess animal fats, which makes it more versatile than bioethanol.
Due to the high amount of caloric density available, this fuel can actually be used in areas where diesel has been traditionally used. This makes it a sound investment for the future.
3. Hydrogen Fuel
Hydrogen fuel is another type of completely renewable sources of energy. It can be derived from biological or chemical processes, which means that there are a variety of ways to manufacture it.
The reason hydrogen fuel may be worth investing in concerns the fact that automobiles that use hydrogen fuel cells may one day replace gasoline-powered cars for everyday transportation.
4. Tire-Derived Fuel
Tires have traditionally been thrown in landfills and disposed of rather than reclaimed due to their high recovery costs. Eco green equipment is used to recycle tires into fuel and is therefore one of the few ways that these byproducts that would normally fill up landfills can be reused in a cost-efficient manner.
This allows investors to purchase used tires no longer fit to be used on vehicles and to recycle them into energy.
5. Processed Engineered Fuel
PEF is a type of semi-renewable fuel derived from products that would otherwise be thrown into a landfill to decompose. Investing in the process is a sound decision, as it simultaneously decreases the rate landfills grow while providing an alternative source of fuel for people to use.
6. Compressed Natural Gas
CNG is a methane substitute for gasoline. It’s another alternative to fossil fuels available in the short term.
The thing that makes it a sound investment is that it’s already in use by many municipalities around the world for everything from worker vehicles to public transportation, such as in the United Sates, the United Kingdom and Brazil.
