Global warming potential and energy consumption.
Making matters worse coal mining produces methane a greenhouse gas with a global warming potential 25 times greater than that of co 2.
Energy and gwp results are presented per functional unit which allows us to avoid the allocation of environmental burdens among specific waste fractions or refined products.
Global warming potential gwp is the heat absorbed by any greenhouse gas in the atmosphere as a multiple of the heat that would be absorbed by the same mass of carbon dioxide co 2 gwp is 1 for co 2 for other gases it depends on the gas and the time frame.
Global energy consumption is dramatically increasing due to our quest for a higher standard of living and the increasing world population.
A reduction of the energy consumption per capita to less than 20 000 kwh per year as a global warming solution is a challenge for all industrialised countries see chart above.
Anthropogenic ghg emissions based on 100 year global warming potential and about 93 of total u s.
Specifically it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time relative to the emissions of 1 ton of carbon dioxide co 2.
To develop global sustainable strategies there is a need.
Fossil fuels coal petroleum and natural gas are our main sources of energy producing the vast majority of fuel electricity and heat used by people across the globe.
Most of our energy comes from fossil fuels and burning these fuels causes environmental problems and in particular the global warming problem.
Energy and global warming.
Based on the importance and globally most concern on environmental impacts particularly in the building sector two environmental impact categories including global warming potential gwp and non renewable energy consumption were included in this study.
Basically there are two potential ways to achieve this goal.
Energy efficiency and global warming potential in the residential sector.
In 25 years the total global warming potential of a traditional building will be 20 higher than that of a modern building.
However the use of thermal insulation in the modern building walls helps to reduce the energy consumption for space heating and consequently to reduce the global warming potential.
The global warming potential gwp was developed to allow comparisons of the global warming impacts of different gases.
To assess energy consumption we used cumulative energy demand ced hirst 1974 which accounts for all.
Carbon dioxide emissions from other anthropogenic sources and activities were about 7 of.
Some gases like methane have large gwp since a ton of methane absorbs much more heat than a ton of co 2.
