Geothermal energy with all its pros and cons is a hot topic of discussion in recent times and rightly so with the whole world looking out for better means of saving on energy, conserving our natural resources for our future generations.
So what is geothermal energy?
‘Geothermal’ is of Greek origin which means ‘heat of earth’ and the two types of geothermal energy that we mainly identify are the geothermal heat generated from the magma of the planet produced due to atomic reactions.
Do you know what the temperatures are like at the centre of the earth? An incredible heat of ~7200 F or ~4000 C! This heat turns rocks into liquid which slowly moves towards the surface of the earth.
The second kind of geothermal heat is generated from the sun which heats up the first few meters of the surface area of planet earth and this heat can also be harnessed for being used as energy.
How can geothermal energy help mankind?
Geothermal energy can be harnessed and utilized by mankind for their energy needs without exhausting fossil fuel which is a non renewable source of energy.
Geothermal energy can be used for both warming and cooling since it can produce heat during the cold months for warming and cooling is possible using this energy during the hotter months.
This energy can be utilized for meeting the warm water needs in homes and other establishments.
Though you have various Geothermal Energy Pros And Cons the advantages offered by this alternate source of energy far outweigh the cons and hence a great way to reduce energy bills considerably.
Geothermal energy pros and cons
First let us see the pros of geothermal energy
Sustainability is the main benefit of geothermal energy since it is a part of the renewable sources of energy such as wind power, solar heat, etc., the heat that emanates from the earth is considered to be almost limitless.
Eco friendly and sustainable energy is what geothermal energy is all about; it neither causes long term damage to our precious environment nor pollutes the air we breathe, making our planet a better place for our future generations to live in.
When it comes to the material aspect, using geothermal energy helps us save a lot of money on our energy bills and in about 6 to 8 years it would pay off your initial investment from which time you get to enjoy free electric power, great!
Geothermal energy is safe to use; no carbon monoxide poisoning, no catching fires, no radiation and no repairs.
Geothermal energy not unpredictable like other eco friendly energy solutions such as wind and sun; you have uninterrupted supply of energy all through the year irrespective of the season or weather.
Availability is unrestricted since geothermal energy has infinite capacity.
Geothermal energy can be used for various purposes both in residential and commercial electricity generation.
Few of the cons of geothermal energy
Initial expenditure to set up the system is high
Geothermal energy requires a reasonably large area to install the system hence not feasible for small city homes.
Even after installing a geothermal energy plant we would still need electric power to operate the heat pump.
In conclusion after looking at geothermal energy pros and cons we can confidently say that this source of energy is totally clean and sustainable to power your energy needs and also less expensive than solar energy; go for it if you are an environmentalist or not, you can save a lot of money too!
