But that analysis is biased against the bicyclist, because it doesn't include the breakdown of embodied energy
for the motorist.
Dyesol's third generation Dye Solar Cell (DSC) technology has lower embodied energy
in manufacture than traditional silicon solar cells and produces electricity well in low light, real world conditions such as cloudy days, hazy or polluted days, dawn and dusk - not just at peak sun at noon on a sunny day.
Beside good and consistent thermal and acoustic performance overtime, a good and marketable insulation material should in fact be self-extinguishing, not degradable, unshrinkable or non-settling, safe during handling and installation, low cost and should not pollute the indoor building environment, while having a low embodied energy
, proven through LCA assessment.
One measurement that helps builders and future homeowners compare various materials' environmental impact, embodied energy
(EE), totals the amount of energy invested in a product during sourcing, shipping and installation.
Life Cycle Assessment--Assessing carbon footprint, embodied energy
and other environmental impacts for buildings, infrastructure, plus cement and concrete production.
CLEAN ENERGY PRODUCTION FROM WIND AND SOLAR NOW SURPASSES THE EMBODIED ENERGY
REQUIRED TO MANUFACTURE THESE SYSTEMS AND RELATED COMPONENTS, STANFORD RESEARCHERS SAY.
MB: There is this ongoing discussion about embodied energy
and whether the greenest building is the one that is already standing I'd like to get your opinion: Is it better to retrofit or to build new?
In terms of the carbon emissions of the panels themselves, a straw bale has a very modest 1 kgCO2 per cubic metre in comparison to conventional bricks and concrete blocks which have an embodied energy
of 374 and 152 kgCO2 per cubic metre respectively.
Up to 80 per cent of the embodied energy
in a meat tray is typically in the production of the resin, while the remainder is in the extrusion and thermoforming stages.
It is certainly more of a milestone than a millstone and will apparently repay its embodied energy
investment very quickly.
Making better use of existing office buildings and saving the embodied energy
could save more than 20% of current energy consumed.
These local materials contain little embodied energy
and the modular sections can be easily constructed by local labor.
