Creating air bases and then later vacating them after intensive use has caused harm, as has the failure in airpower’s first seventy years to create aircraft than can be repurposed or deconstructed with minimal environmental harm. The book argues that, during both peace and war, air forces have far greater carbon footprints than armies and navies.
Low-power or insulated versions of these devices give off less heat for the air conditioning to remove. The air conditioning system can also improve efficiency by using a heat sink that is cooler than the standard air heat exchanger, such as geothermal or water. In cold climates, heating air and water is a major demand for household energy use.

Life arose from the Earth's first ocean, which formed some 3.8 billion years ago. [33] Since then, water continues to be the most abundant molecule in every organism. Water is important to life because it is an effective solvent, capable of dissolving solutes such as sodium and chloride ions or other small molecules to form an aqueous solution.
