Reusing. Recycling uses a lot of energy.
No. The US uses much more energy than Canada.
The kidney, proportionally uses more energy than the heart because of the amount of energy it uses in active transport reabsorbing substances (amino acids, glucose).
no red uses more energy
Yes, the high voltage power tools do perform better than those that are not. If not necessary, other tools would save on electricity.
It uses less fuel (electricity) and that elecriticy is converted more into infare rays (light)and less thermal energy (heat).
energy is energy It does not matter what you are using the energy for, it matters how much energy you are using A 200 watt light bulb uses more energy than a 100 watt light bulb A 200 watt motor uses more energy than a 100 watt light bulb A 200 watt heater uses more energy than a 100 watt light bulb
No. The US probably uses the most energy in the world.
Florescent bulbs are more efficient and uses 40-50 % of the input energy . Moreover it lasts for a longer time and is cheap.
A person who - on average - eat more energy than (s)he uses up will gain weight
A computer uses more energy than a 60 watt lightbulb
