Embodied Energy

Embodied Energy

The total energy required to produce a product.

Energy utilization

The method with which energy is used

• Total energy consumed in production (cradle to [factory] gate) and throughout the lifecycle of a product (cradle to grave)

• It is the sum of all energy needed to produce a product or service.

• It is highly useful to calculate how successful/effective a product or service produces or saves energy.

Distributing Energy: National and International Grid Systems

An electrical supply distribution network that can be national or international. International grids allow electricity generated in one country to be used in another.

Energy Distribution

The method with which energy is transported from a source to where it is used.

Local Combined Heat and Power (CHP)

A system that simultaneously generates heat and electricity from either the combustion of fuel, or a solar heat collector.

Individual energy generation

The ability of an individual to use devices to create small amounts of energy to run low-energy products.

Quantification of carbon emission

Defining numerically the carbon emissions generated by a particular product
