Fans are the cheapest cooling option to run and have the lowest greenhouse impact; air conditioners are expensive to run and produce more greenhouse gas. Make fans your first choice for mechanical cooling — they are the cheapest to run and have the lowest greenhouse impact.

Then, what is the most energy efficient cooling system?

The most energy-efficient cooling solution you can install is one that's powered by a roof-mounted solar electric system. Mounting photovoltaic cells on your roof means that you can effectively power your air conditioner for free.

One may also ask, which is more expensive heating or cooling? Heating a home is more energy intensive than cooling because of how the home is heated and cooled. Cooling a home involves moving the excess heat out so that it's cooler inside. Moving heat requires a lot less energy than making it, which is why cooling ends up being less expensive than heating.

Regarding this, what is the least expensive way to heat a house?

What is the alternative to air conditioning?

Evaporative Coolers A more elaborate alternative to air conditioning is an evaporative cooler – also known as a swamp cooler – which cools air by blowing it over water-soaked pads. According to the DOE, this evaporating water can cool the air by anywhere from 15 to 40 degrees Fahrenheit.

What are the two types of cooling systems?

There are two types of cooling systems: (i) Air cooling system and (ii) Water-cooling system. In this type of cooling system, the heat, which is conducted to the outer parts of the engine, is radiated and conducted away by the stream of air, which is obtained from the atmosphere.
