The Facts About HVAC Systems And Greenhouse Gases

The majority of HVAC systems emit greenhouse gases

Do HVAC systems emit greenhouse gases? Many consumers have asked themselves this question. If you’re concerned whether or not your HVAC system is contributing to the depletion of the ozone layer, then you first have to determine what type of HVAC system your home uses. But more than likely the answer is –yes. Most heating and cooling systems burn some type of fossil fuel for energy. Fossil fuels can be either oil, natural gas, or propane. If your heating system uses any of these for energy and heat, then it does emit greenhouse gases into the atmosphere. Even though some heating systems use electricity for heating, they still contribute to greenhouse gas emissions indirectly. The electricity needed to run the heat pumps will most likely come from a power plant that burns some type of fossil fuel to create the electricity.


How do air conditioners emit greenhouse gases?

It may seem like an air conditioner would not emit any greenhouse gases since it does not burn any fossil fuels to produce heat. Beside the fact that it uses electricity from a power plant, air conditioners use refrigerants which are a source of greenhouse gases. Refrigerants consist of chlorofluorocarbons which have been shown to contribute to the depletion of the ozone layer.


Reducing greenhouse emissions

The only type of HVAC system that will not emit any greenhouse gases either directly or indirectly is one that uses no refrigerant and is completely powered by an energy source that emits absolutely no greenhouse gases, such as wind or solar power. While it is feasible to produce HVAC systems that produce very little or no greenhouse gases, they would be extremely costly and time-consuming to create and install. The best way to contribute to the reduction of greenhouse gas emissions is to use heating and cooling systems in the most efficient ways possible.

By using appliances and HVAC systems that are environmentally friendly and carry the Energy Star seal of approval, consumers can greatly contribute to the reduction of greenhouse gases. Performing regular maintenance on heating and cooling systems as well as practicing energy saving behavior can also help in reducing the emission of harmful gases into the atmosphere.

America Needs To Adjust To Growing Global Warming Impacts

Global warming impacts are only likely to grow in severity over the coming years, according to the vast majority of the world’s climate experts. Scientists predict a rash of likely effects on the world’s environment, including warmer summers and higher temperatures generally. This is almost certain to disrupt the world’s weather patterns, increasing the chance of freak weather events, and perhaps altering the climates of many countries across the world.

Certainly, people are going to have to ready themselves to adapt to this rate of change. A warming world means higher sea levels, which means a much greater risk of flooding, unbearably hot weather, and storms. The US government’s own National Climate Assessment puts it in rather blunter terms: “This National Climate Assessment concludes that the evidence of human-induced climate change continues to strengthen and that impacts are increasing across the country.”

You might work in agriculture, where the effects of a changing climate can seriously affect your livelihood. Higher temperatures and warmer summers can seriously disrupt growing seasons, as well as affecting irrigation. The greater risk of droughts could well put many farmers in the USA out of business, and much sooner than has previously been anticipated.

A changing climate can also have serious effects for homeowners. Higher temperatures can make it hard to live and work in some parts of the USA, especially those places where summers are already very hot, such as Arizona. Owning air conditioning is going to be become a key part of staying healthy, and even alive, with a professional HVAC technician likely to become an ever-more-important person to know.

The 800-page National Climate Assessment makes a point of stating that the effects of climate change are occurring now. Whereas many people, and a number of climate experts, thought that the effects could be many years away from reaching their peak, that opinion is changing. Many scientists assert that the consequences are already being felt, by oyster farmers in Washington State as much as by corn growers in Iowa.

The end of the 21st century could see temperatures rise as much five degrees, a huge increase. Even with aggressive attempts to reduce greenhouse gas emissions, they could still rise by as much as 10 degrees, according to the Assessment. Dealing with the consequences of such an increase is likely to be challenging and testing for the human race.

The National Climate Assessment does not carry good news for anyone. Ignoring it, or pretending that the situation does not somehow exist at all, is likely to be very costly, for America and the world.
