COMENDA ECO2 & CARBON FOOTPRINT
POWER
A lightbulb’s common measure is Watt (W): example 100W
This measure give us the idea of it’s capacity to illuminate, in other words: POWER
ENERGY
Switching on 10 of these lightbulbs for 1 hour means;
10 x 100W x 1h = 1000Wh or 1 kWh
This indicates the capacity of the lightbulbs to illuminate over a period of time consuming: ENERGY
POWER / ENERGY
When we stipulate a contract for electrical power:
The Power (kW) required is determined by the power of the machines, lamps etc we need to connect , the electric company will supply this power at a set price . The Energy (kWh) used determines the actual electrical consumption and electricity bill we will receive.
CARBON FOOTPRINT
Generating kWh means also producing Carbon Dioxide CO2, having a negative effect on the environment and global warming.
CO2 is used to give a measure of how much machines pollute the environment, the more CO2 produced, the more negative impact on the environment.
- Each country has it’s own Carbon Footprint measure on the basis of how it’s energy is generated.
- The calculation takes into consideration the origin of it’s energy supplies such as; thermoelectric, nuclear, hydroelectric, solar, wind generators.ecc.
