A sufficient lifestyle means to be frugal with the available resources without compromising one's own satisfaction and quality of life. This mentality manifests itself on the one hand in a more conscious and reduced consumption behavior, on the other hand, however, sufficiently-living people often live in a more self-determined, independent, conscious, healthy, relaxed and satisfied manner.
Only by combining efficiency and sufficiency measures can a truly sustainable development be driven forward and greenhouse gas emissions reduced. Because the improvements in efficiency are negated by the lack of consideration of sufficiency. Especially with electrical appliances, such developments can be found: The energy efficiency of televisions is getting better, but at the same time they are getting bigger and sales are increasing. Refrigerators are energy efficient, but at the same time they are bought unadapted to the number of people in the household. Because a big fridge is handy. And the large cooling volume destroys technological progress and high energy efficiency.
Simple ways to live yourself more frugal, are the conscious renouncement of consumer goods, meat or long vacations, shopping in packaging-free shops or local markets, the exchange and sharing of goods or the repair and recycling of defective equipment, furniture or clothing.
