Global Warming Potential And Energy Consumption

Some gases like methane have large gwp since a ton of methane absorbs much more heat than a ton of co 2.

Global warming potential and energy consumption.

Anthropogenic ghg emissions based on 100 year global warming potential and about 93 of total u s. The impacts of interest are total energy consumption and gwp. 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. Carbon dioxide emissions from other anthropogenic sources and activities were about 7 of.

Basically there are two potential ways to achieve this goal. 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. Energy and global warming.

Most of our energy comes from fossil fuels and burning these fuels causes environmental problems and in particular the global warming problem. To develop global sustainable strategies there is a need. 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 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.

To assess energy consumption we used cumulative energy demand ced hirst 1974 which accounts for all. Comparative evaluation of canada and saudi arabia. In 25 years the total global warming potential of a traditional building will be 20 higher than that of a modern building. Energy efficiency and global warming potential in the residential sector.

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. 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. 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. In 2018 carbon dioxide co2 emissions from fossil fuel combustion burning for energy were equal to about 75 of total u s.
