The way that a person heats their house can add to global warming. Some ways  include pellet stoves, electric heating, gas heating, and wood heating. The average furnace uses natural gas, propane, electricity, or oil to heat the air and push it through the house. Electric heating is the most expensive form of heating, according to the U.S. Energy Information Administration. Electric heating is more expensive due to the generation of electricity and transmission losses. 

Natural gas is used to heat over 50% of houses nationwide according to the U.S. Energy Information Administration. Natural gas prices have been on the rise over the years and are only getting higher. Natural gas prices rose to $2.90 per gallon compared to $2.20 in 2023. The price of natural gas increased due to the international demand and the growing decrease of it according to Couch Oil Company. 

While electric heating is 100% efficient, gas heating is only 55-97% efficient, according to Greener Solutions Heat and A.C. While the costs of gas heating rise, the materials needed to make natural gas are depleting. When people mine these resources, gasses are emitted into the atmosphere. In order to make electricity, fossil fuels need to be burned. Burning these fuels releases carbon dioxide. Due to carbon dioxide being released, global warming has been on the rise. 

Global warming has been making the global temperature hotter. Since the seasons are getting warmer, people tend to not use their heating systems until later in the year. Many people leave their heating off as long as they can. However, some people have it by mid September according to the Energy Saving Trust. 

When people leave their heating system off for as long as they can, they reduce the amount of toxins that are emitted into the atmosphere. 

When a person uses pellets to heat their house, they usually buy their pellets in the tons. Pellets are usually made from wood or wood processing by products like sawdust. A typical house can go through two and three tons of pellets per year. This can cost between $200 and $300. They are 70 - 83% effective according to the Department of Energy, which makes them quite efficient as a way to heat a house, especially compared to electric heating and natural gas.

Finally, there is wood heating. Wood heating is more expensive than gas and is far more hazardous. It can cost around $600 to run a wood stove according to Regency Fireplace. The cost of wood depends on the type of wood, the chopping of the wood, and the moving of the wood. Burning wood is 80% efficient in heating your house according to The Firebird. 

There are many types of heating, and all of them are efficient to a degree. The cost of heating grows every year due to the lack of materials and ways to get them. Also with each resource mined and burned, more greenhouse gasses are emitted which fuel global warming. It is important to know how heating will affect the environment.
