A study of the world’s air conditioning supply system found that countries like Japan, South Korea and the US have the most efficient and affordable systems.
The researchers say the findings highlight the need for governments to consider new technologies to tackle climate change.
The researchers looked at more than a million systems in more than 200 countries and compared them to their energy use and energy efficiency.
They found that air conditioning systems in developed countries are among the most energy efficient, with systems in the developing world averaging 1.5 times less energy use per unit of energy produced than in developed nations.
Australia, for example, uses about 10% less energy per unit power produced than the average US system.
But it is the cheapest in the world, with its average electricity usage in the study about 15% lower than the US.
This comparison was made by the authors of a paper titled “Energy efficiency in air conditioning” published in the journal Nature Energy.
The paper says the research is an “in-depth analysis” of the energy consumption of systems in a variety of countries.
“The results highlight the importance of considering the needs of consumers and the global economy,” lead author Simon Rees, a senior researcher at the University of Queensland, said in a statement.
Rees and his colleagues looked at the energy used by more than 10 million systems around the world.
They used data from energy efficiency ratings for air conditioner systems that use the same technology, and found that the cheapest systems used about 5% less electricity than the most expensive.
For example, in South Korea, an air conditioning system uses less than 0.03% of the electricity used by a standard home.
In Japan, it uses less 10% of that energy.
Rees said that this means the systems in Japan are the least energy-intensive in the region, and that is what consumers are using.
A system like the one used by Japanese Prime Minister Shinzo Abe uses 1,200 watts per square meter, which is about the same as the average American home, the study said.
That is about 5,400 times more energy than the system used by the United States, which uses about 11,000 watts per sq meter.
But Rees and other researchers say air conditioning systems need to be better designed to ensure that consumers have enough energy to heat their homes and businesses.
They found that some of the best energy efficiency systems are in the US, where the average energy efficiency of the systems used by residents was about 7.5%.
But even in countries where energy efficiency is less than 10%, the systems still consume an average of 8.7% less power than the lowest energy-efficient systems, which are used by people who do not live in buildings, according to the study.
In the US and Canada, the average efficiency of an air condition, heating or cooling system was about 20%.
The average in Europe was about 30%.
The study found that energy efficiency was linked to other important factors such as how much money people spend on heating and cooling and whether their households are in urban or rural areas.
And while it is not clear whether people who live in cities are better off because of air conditioning technology, the researchers say that the energy efficiency can make a big difference in the lives of people who are dependent on public transportation.
As temperatures increase in developed areas, the amount of time people spend walking can decrease.
The study found a link between the amount people spend getting around and the energy they use to walk.
Air conditioners were already popular in China, Japan and other developing countries before the air conditioning market exploded in the 1990s, with more than 40% of all households now using them, according the New York Times.
More than 80% of households in China and China-owned businesses are using air condition.
The report said the average amount of energy used per unit watt is about 8,000 times less than the United Kingdom’s.
