Geothermal pumps re-emerge for long-term avoidance sought by American families

If you dig 6 feet underground, you will find underground temperatures in any part of the United States remain between 45 and 75 degrees Fahrenheit. This provides unique conditions for the use of geothermal energy. Heating a home with a heat pump is a typical use of geothermal energy. Despite the high cost, many advantages such as simplicity, reliability, noiselessness, and low pollution have made geothermal heat pumps more and more important.

Unlike in Europe, geothermal pumps have not really been promoted in the United States, at least so far. In fact, the reserves of geothermal resources in the United States are surprisingly large, but the utilization rate is still less than 1%. Americans do not seem to have this type of home heating. However, with the continuous expansion of the geothermal pump market in the United States in recent years, there has been considerable progress in supply, sales, and services, and a market network has been formed. At the same time, geothermal pump distributors are beginning to realize that the American people who have not had contact with geothermal energy in the past have accepted this new thing and must vigorously publicize their advantages.

Objectively speaking, although the United States has abundant geothermal resources, geothermal pumps are not "wild" home heating methods. Although geothermal heat pumps work well in most areas, the use of geothermal heat pumps is somewhat more troublesome than conventional heating methods. In addition to understanding what type of system is suitable, the installation cost and energy consumption cost also need to be known, and the installation of geothermal heat pump is also relatively complicated, which has caused many users who are interested in it to retreat. .

So why should a geothermal pump be chosen for a family? First of all, the most attractive place for geothermal pump heating is its high efficiency. This means that electricity consumption can be saved, thereby effectively reducing electricity bills.

Geothermal pump technology has been constantly evolving since geothermal heat began to be used in the United States in the 1940s. Compared to the use of air conditioning for heating or cooling, the efficiency of geothermal pumps is clearly much higher, but also more reliable and long-lasting. A geothermal pump can last up to 25 years to 50 years.

In addition to its high efficiency and long-term use, geothermal pumps also have the advantages of low noise and low maintenance costs. No matter how you look at it, it's a good deal. In Oklahoma, a 280-square-meter house uses geothermal pumps, which cost just $60 a month to meet all energy needs.

However, the use of ground-source heat pumps requires consideration of many factors, including local geological conditions and other uncertainties, and the promotion of geothermal pumps still faces many obstacles. At present, the United States already has nine geothermal power stations in California, but the overall rate of development of geothermal utilization is still relatively slow and difficult. Because you want to build large-scale power generation facilities must be drilled deep underground. Many times a project needs to obtain tens of thousands of dollars for pre-exploration. On average, every mile drilled into the ground requires dozens of diamond drills, and a drill has at least $2,000. However, deep penetration into the ground may not find enough reserves. Therefore, it is also necessary to pay for the development of underground thermal energy. In addition, the cost of installing geothermal pumps is also difficult to estimate. Due to the different geographical conditions in different regions, it is difficult to count a representative use cost of geothermal pumps.

However, these have failed to stop the government's determination to promote the development of the geothermal industry. In addition to home heating and cooling systems, geothermal power is also an important use of geothermal energy. According to statistics issued by the American Geothermal Energy Association in 2010, geothermal power has enabled the United States to have a total installed capacity of 3.15 GW, making the United States the world's largest geothermal power producer. In 2011, the geothermal industry in the United States continued to accelerate development. The information released by the Geothermal Energy Association (GEA) in April 2011 showed that in the next few years, geothermal energy production in Texas will be expected to quadruple, and geothermal power generation will also be Nine states have expanded to 15 states. California is the U.S. that uses the most geothermal power. Idaho followed closely. It is estimated that by 2015, geothermal power generation in Idaho will reach 855 megawatts, and by 2025 it will reach 1670 megawatts.

Since 2009, geothermal power in the United States has shown strong growth. From August 2008 to March 2009, the newly built and under construction geothermal power station in the United States has 1,500 megawatts of new capacity. If we can scientifically develop underground geothermal resources in various states, we will be able to meet 25% of the total national energy demand.

The U.S. uses geothermal energy to rank third among all renewable energy sources, second only to hydropower and biomass, but is more widely used than solar and wind energy. According to the statistics of the United States Geothermal Resources Association, the total amount of geothermal power generated in the United States has reached 2,200 megawatts, which is equivalent to that of four large nuclear power plants. Today, geothermal pumps are beginning to become increasingly popular in the United States. The annual installed geothermal pump users is about 50,000 households. This figure will continue to grow with the continued development of the US geothermal heat pump market. With the increase in propaganda, more and more people began to understand this kind of energy that has been abundantly stored in the United States but has been neglected in the past. With today's ever-increasing demand for electricity and unfavorable economic conditions, heating methods that can save money are absolutely welcome for every family.

It is worth mentioning that among the clean energy, the cost of geothermal power generation is also relatively low. According to the analysis of the International Geothermal Association, the cost of geothermal power is only about half of the cost of wind power generation.

For such energy with abundant reserves and outstanding advantages, the U.S. government should naturally increase its use of energy. Although the U.S. geothermal power generation currently ranks first in the world, it is still not large in scale. Although there are some problems that have not yet been overcome, what kind of renewable energy is not the case? Geothermal heat pumps, as long as they can do their best to avoid weaknesses, I believe that geothermal energy will certainly be able to occupy a very important position in the United States future energy architecture.
