This chapter deals with a study on the effect of using a geothermal-based absorption cooling system and its impact on the environment through greenhouse gas reductions. It also compares the emissions for various fuel options and discusses opportunities for combating the global warming. It is shown that using such absorption systems will help reduce greenhouse gas emissions. Moreover, it is observed that increasing the indoor air temperature by 5°C (e.g., from, 20 to 25°C) will increase the SO2, CO2, and NOx emissions by about 80%, respectively.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
