Inverter Air Conditioners Reduce Global Warming

Limiting global warming can start with air conditioners.

Air conditioners are the fastest-growing energy demand in homes and buildings, adding millions of tons of carbon dioxide to the atmosphere. Fortunately, we don’t have to wait to make changes. Solutions are already available. Variable-speed inverter air conditioners — offered by many companies — are the most efficient air conditioners on the market.

Switching out old air conditioners to inverters could cut energy use in half.

Air conditioners can even help utility companies avoid blackouts because they automatically run on partial power, rather than turn completely off.  However, despite their higher efficiency, less than 5% of homes in the US use inverter-driven technology. And because some can be more costly, many manufacturers don’t promote them as actively as they could.

Air Conditioners Use 6% of All Electricity

Globally, air conditioner represents 4260 trillion BTUs of energy per year.

Inverter Air Conditioners Save Energy.

On March 3rd, 2019, Eneref Institute presented our argument for “Cool Room. Cool Earth.” to the media.

“Eneref Urges More Rebate Incentive Programs to Spur Quicker Adoption of Inverter Technologies in Residential and Commercial HVAC Equipment.”

What Actions Can We Take to Make a Difference?

What to Do
What to Say

Right now, we need to make unprecedented changes to ensure a sustainable and equitable society. Every extra bit of warming matters.

Eneref Institute is encouraging air conditioner companies to promote their inverter technology over their less-efficient systems.

You can also call your governing agencies across the US — and around the world — to create incentive programs to help consumers and businesses replace their inefficient systems with energy-saving inverter air conditioners. Let’s make cool rooms… And a cool earth.

  1. INVERTERS EFFECTIVELY REDUCE GLOBAL WARMING

    A 30% improvement in air conditioning efficiency could reduce global CO2 emissions by up to 25 billion metric tons over the lifetime of the equipment, according to a 2016 US Department of Energy report. That’s the equivalent of eliminating the annual emissions of 1,550 coal-fired power plants.

  2. INVERTERS MINIMIZE ENERGY USE

    Inverter systems ramp up to the desired temperature quickly and then hover at the ideal temperature, working like a sort of cruise control. For this reason, inverters use minimal energy compared to conventional constant-speed air conditioners, which run at full capacity. Inverter systems typically need to operate at full capacity at less than 10% of the time.

  3. INVERTERS NATURALLY RUN QUIETLY

    Because variable speed inverters work at a lower capacity, less power is consumed, offering quieter operation. Inverter systems are not only smoother in operation and better under extreme temperatures, but they also reach the desired temperature, or set point, more quickly.

  4. INSTALLING CONTRACTORS CAN SAVE

    Conventional air conditioner systems are often specified for the worst-case scenario — oversized, for maximum load. Because inverter technology is more precise —  they burn only as much energy as needed — inverters allow contractors more flexibility in how they specify systems.

  5. HOW TO GET STARTED

    The roadmap to more efficient residential air conditioners should begin at the local level. Call your local representative and ask about energy incentive programs for inverter-driven technology.
