Did you know that central heating goes all the way back to Ancient Rome? Back then, air was warmed by furnaces before being conducted through empty spaces beneath floors and coming out of pipes in the wall. This system was known at the time as a hypocaust. So much has changed when it comes to heating and cooling units for homes since then!
Modern central air and heat units use up a lot of energy. Energy costs associated with heating and cooling Virginia Beach have been rising steadily since the later half of the 20th century, and one reason is increased worldwide consumption. As of 1980, the U.S., despite being home to just 5 percent of the global population, was consuming more air conditioning than the total amount used by every other country in the world put together. There must have been a whole lot of air conditioning maintenance going on then! From 1993 to 2005, summers became ever hotter and the size of family homes ballooned. This state of affairs coincided with the average amount of energy consumption by air conditioners in the United States doubling during those years.
Right now, central air and heat units are flying off the shelves, and not just in America. In 2011, 55 percent of new central air and heat units were sold in Asia. As global standards of living continue to change, by 2020 China is expected to surpass the United States to become the biggest user of electricity for central air and heat units in the world.
The increased need for energy consumption by central air and heat units could create a number of problems over time, for example, increased pollution and poor air quality. This is definitely the case in America, where approximately 50 percent of all energy consumed is generated by coal. Coal is not an energy efficient fuel for central air and heat units. Therefore, we must strive to replace coal with other more environmentally friendly methods of fueling central air and heat units in this country, just as we once replaced lead plumbing with copper when we discovered that lead was poisonous. Coal is poisonous as well, and it must be phased out, the sooner the better. More research here.Share This : by
