What Are the Advantages and Disadvantages
of Geothermal Energy?
Geothermal energy offers those of us who live on the earth the ability
to tap into
the earth for a new, renewable source of energy. Once discovered, it was a
revolutionary solution that quickly spread from one end of the planet to the other.
But as with any other solution, if you are considering geothermal energy for your
home, you’ll want to take a look at the advantages and disadvantages it
produces. So, to help you out, we looked around to discover some answers
to your questions - “What are the advantages and disadvantages of
The Advantages of Geothermal Energy
When it comes to the advantages of geothermal energy, they are numerous.
To give you an idea of just how many there are, be sure to check out this list:
First and foremost, geothermal energy is renewable, meaning that as
long as we don’t pump too much cold water into the earth -cooling off the hot
rocks- the energy will just keep on coming!
Secondly, geothermal energy doesn’t
produce pollution, and at the same time, it doesn’t contribute to the greenhouse
The power stations for geothermal energy
don’t take up a whole bunch of room, and because of this, they tend to have less of an
impact on the surrounding environment.
Because geothermal energy is energy in
and of itself, no outside sources of fuel are needed to keep the power houses
And, even better, geothermal efficiency
offers an even more exciting benefit to the frugal homeowner - once you’ve built the
geothermal power station, the energy is nearly, well, free! While it may require a
little energy to actually run the pump, you can tap into the energy that is already
being produced to handle this task!
The Disadvantages of Geothermal Energy
As numerous as the benefits of geothermal efficiency are, there are still some
drawbacks that you’ll have to face. And these disadvantages can affect any
or all of the three phases of production - pre-production, production, and
Perhaps the biggest drawback when it comes to geothermal energy
is that you just can’t set up a geothermal power station anywhere you
want. First of all, you’ll need a location that offers just the right kind
of hot rocks. Just any hot rocks won’t do, since some rocks might prove
too strong to drill through. These rocks also need to be within a
reasonable depth to make drilling down to them a feasible option.
Volcanic areas often provide the most geothermal efficiency.
There’s also another risk to consider - sometimes a geothermal site
might, well, literally run out of steam. And when this happens, the
dry spell may last for periods that reach into the decades!
The last disadvantage we’ll cover concerns the potential danger of
geothermal energy. When you are drilling into the earth and steam
is able to escape, other - not so friendly - things might escape too.
Hazardous gases and minerals can seep up from beneath the ground,
and finding a way to safely dispose of them may prove very difficult and dangerous.
Anytime you’re considering making an energy change in your home, it’s important
to weigh the pros and cons of the decisions you’ll be pondering. Geothermal
energy, just like any other form of energy, poses many benefits, along with a
few drawbacks. But, if you live in an area where geothermal energy is a viable
solution, consider having a geothermal site builder stop by for a consultation.
As professionals in the trade, they’ll be able to offer a more thorough
explanation of the risks, benefits and behind-the-scenes information about
geothermal efficiency and what it can mean for you!
And, don’t forget, there’s another important and more practical use of geothermal
energy in the home via geothermal heat pumps. Geothermal heat pumps are
similar to other heat pumps in the sense that they take heat from an outside
source and bring it inside of your home. But the difference is that geothermal
heat pumps rely on the stable, even heat from the earth to provide heating,
air conditioning and hot water for your home, instead of using outside air.
The costs of the equipment are slightly higher than other forms of heating,
but the pay off is better in the long run. Geothermal heat pumps are far more
energy efficient than furnaces or boilers, and the money you save on your
energy bills will more than cover your initial investment in equipment, maintenance
By using this form of geothermal energy, you bypass many of the disadvantages
and cash in on the positive aspects. And, geothermal heat pumps impact the
environment even less than other methods of geothermal heating!
Disadvantages about geothermal energy and geothermal heat
First of all I want to say that geothermal heat pumps are by far the most energy
efficient, green, environmentally friendly heating and cooling source available. Now I’m
an expert in residential energy efficiency so I’m well aware of solar power, it’s costs, and uses.
I’m aware of gas furnaces, propane, wind power, and water power, but when it comes to
the most energy efficient source available, a geothermal heat pump, or ground source heat pump, wins the
price. Learn more =>
