Šveitsis käimas huvitav 2000-Watt Society projekt. Eesmärgiks on tänane energiatarve ühe kodaniku kohta päevas 6000W langetada 3x 2000W peale.

Vatt (W)

Et veidi piltlikumalt aru saada siis väike võrdlus:

A person having a mass of 100 kilograms who climbs a 3 meter high ladder in 5 seconds is doing work at a rate of about 600 watts.
A laborer over the course of an 8-hour day can sustain an average output of about 75 watts.
A typical household incandescent light bulb has a power rating of 25 to 100 watts; fluorescent lamps typically consume 5 to 30 watts to produce a similar amount of light, while comparable LED lamps use about 0.5 to 6 watts.


Inimese võib lihtsalt võrdsustada 100W pirniga:

How do you compare to a 100 watt light bulb? A human being must take in about 2500 Calories (kilocalories) of energy in his or her food each day in order to continue to function properly. This means that he or she uses up energy at a rate of (power) of 2500 kilocalories/day. Using the fact that 1 calorie = 4.2 joules, and the appropriate time conversions show that this rate of energy usage is about the same as a 100 watt light bulb.

The vision of a 2000-watt society would mean reducing the energy demand per capita in industrial nations by two thirds within five decades. If one assumes that income and consumption will continue to grow by two thirds during this period, this would mean using energy five times more efficiently than is done by today’s technology.

Is this technically and scientifically feasible? Could industrial nations still operate with 20% of today’s energy demand, but at the same levels of consumption, mobility and production? A detailed technical-scientific analysis by 10 Swiss scientists came to the conclusion that such a vision is indeed “technically feasible”.
