Regular HVAC units which are used by many people today contribute to pollution and climate change. Carbon monoxide is produced by common household appliances. When not properly ventilated, carbon monoxide emitted by these appliances can build up. Not only does it hurt the earth because it is a greenhouse gas that will eventually contribute to the heating of the earth but it hurts people. If people keep using these systems eventually it will have a big affect on the earth. Also carbon monoxide kills about 500 people a year some coming from their cooling systems. Like I said above if your system is not properly ventilated the carbon monoxide from your AC can build up and be detrimental to the health of a human. Not only do these systems physically hurt people and the earth but they also hurt their wallets. HVAC systems cost more than $2000 more than geothermal systems every month.

All of these problems can easily be solved with geothermal cooling systems. The way geothermal systems work is pretty simple. First a pump filled with water is sent directly into the approximate 50 to 60 degree F range deep earth. Since it is under the earth it is a very reliable source because it wont heat up more than a few degrees in the summer and it wont cool down more than a few degrees in the winter so you can always get the cooling you want. Geothermal systems also do not have any outside units just pumps in the ground so there is no carbon monoxide poisoning to the earth or people. Geothermal fixes all the problems listed above. In the future if people switch over to geothermal they will be happier because they will be saving money and they will be living on a cleaner earth.

Even though it is only a small amount geothermal energy has been getting more popular in America every year. The Geothermal Energy Association announced in 2012 that geothermal use has gone up 5% every year. The last major advancement in geothermal energy is called the enhanced geothermal system. An enhanced geothermal system generates geothermal electricity without the need for natural convective hydrothermal resources. Until recently, geothermal power systems have exploited only resources where naturally occurring heat, water, and rock. EGS technologies enhance and create geothermal resources in this hot dry rock through hydraulic stimulation. With this advancement people can use geothermal energy in more places.
