Global Warming Potential And Energy Consumption

Factors such as occupancy per household and floor area of a single family residence can contribute to greater energy consumption and ghg emissions per capita.

Global warming potential and energy consumption.

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. In 2018 carbon dioxide co2 emissions from fossil fuel combustion burning for energy were equal to about 75 of total u s. Anthropogenic ghg emissions based on 100 year global warming potential and about 93 of total u s. Comparative evaluation of canada and saudi arabia.

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. Most of our energy comes from fossil fuels and burning these fuels causes environmental problems and in particular the global warming problem. The global warming potential gwp was developed to allow comparisons of the global warming impacts of different gases. The impacts of interest are total energy consumption and gwp.

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. Energy efficiency and global warming potential in the residential sector. 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. In 25 years the total global warming potential of a traditional building will be 20 higher than that of a modern building.

Some gases like methane have large gwp since a ton of methane absorbs much more heat than a ton of co 2. Making matters worse coal mining produces methane a greenhouse gas with a global warming potential 25 times greater than that of co 2. To develop global sustainable strategies there is a need. Basically there are two potential ways to achieve this goal.

Energy and global warming. 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. 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. 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.
