The concept of passive house is a (German) house energy norm ; the term is used for a kind of houses. It's a type of house needing very little energy to run. It provides a comfortable temperature all year round without using conventional heating - in opposition to a conventionally built house.
Having a passive house is a way to lessen one's energy consumption. A building may be called a passive house if it is almost self-sustaining for heat, if it only uses solar panels, metabolic inputs (residents, machines) and a good thermal insulation, so that heating is just an aid.
Fava beans are easy to grow.
They can be eaten fresh, just like radish, with a nice loaf of bread and sea salt and butter or margarine :
a simple, healthy and refreshing vegetarian dinner or as a starter for lunch.
Hybrid vehicles are an intermediary solution between conventionnal vehicles and electric vehicles. The idea is making the thermic motor run with a slightly harder charge than necessary, and use this extra energy to charge batteries.
More than one century of industrial development, economic growth and intensive exploitation of nature has led us to a world where we can travel cheaply to anywhere in the world, import food, clothes and materials from any country, yet we are slowly destroying the very earth which keeps us alive. Despite increases in automation, we are working harder and harder, and neglecting our home lives to fulfil the demands of industry. The brave new world promised to us by technology has not arrived. Instead it has led to an increased gap between rich and poor within most countries and between countries. Cultures once unique and distinct are slowly merging into variations of Western popular culture. Languages and species are dying out. The outlook is gloomy! We have a very strong responsibility to the future which we will create. If we wish to provide a better environment to our children (and ourselves), we will thus have to modify our ways of life and our manner of consuming. Currently, to provide for his needs, Humanity must call upon the industry of consumption.
« We must define the techniques together allowing us to build a better world. »
