Underground Energy Stock

Investing in Geothermal Energy Stocks

What is it about an energy source that makes it useful, let alone valuable? Ask yourself, for example, what is coal? Why is coal useful? It is, as the old saying goes, “the rock that burns.” One coal miner of my acquaintance calls coal a “portable climate.” Among other things, it offers the user the ability to release stored-up heat energy and thus to bring rapid warmth into a cold world. Yes, and so much more.

Or consider what happens when you are driving a car and burning up gasoline. What is it that you really want from your fuel supply? Do you care that gasoline comes from refined crude oil? Or are you more concerned with the fact that the gasoline combusts in the cylinders of your engine, via rapid, explosive release of heat when the gasoline is sparked? You probably learned in drivers’ education class that thebasic, four-stroke internal combustion engine follows a cycle of intake, compression, power stroke and exhaust. When the gasoline combusts and explodes, it releases heat energy, which causes combustion gases to expand and push the power stroke. The power stroke, in connection with the well-timed power strokes of the other cylinders, turns the crankshaft. This is what allows you and your vehicle to move along. So gasoline is also, in essence, a form of stored heat.
