Primary energy consumptionGround-source heat pumpSolar-assisted ground-source heat pumpBoiler systemThe energy consumption and CO2 emissions of heat pump systems can be reduced effectively by adopting an appropriate alternative refrigerant. However, investigation on alternative refrigerants for ground-source ...
Our estimate suggests that wind is currently the most desirable renewable energy in terms of minimizing CO2 emissions per kWh of produced electricity. The production phase contributes the most to overall CO2 emissions, while recycling after decommission could reduce emissions by nearly half, representing...
I = Carbon intensity (the amount of carbon emitted per kWh). M = Embodied carbon (the amount of carbon emitted during the creation and disposal of a hardware device). R = Functional unit (e.g., carbon emissions per additional user, API-call, or ML training run). Example of calculating...
“I’m delighted that our investment in SAF can now be fully leveraged by customers to enable them to bring down the emissions of their shipments. SAF is currently the primary route to reducing carbon emissions in aviation, so this is the most effective way to help our cu...
infrastructure, like bike lanes and sidewalks, and digital trade and intelligent supply chain management can also reduce transportation needs and thus decrease CO2emissions1,25. In addition, promoting the development of new energy vehicles can help lower the carbon intensity of transportation per capita...
Annual CO2 emissions from fossil fuels by major country and rest of world from 1959-2017, in gigatons CO2 per year (GtCO2). Note that 2017 numbers are preliminary estimates. Data from the Global Carbon Project and available here. Chart by Carbon Brief using Highcharts. ...
Worldwide electricity use is responsible for a quarter of all carbon dioxide (CO2) emissions. However, by taking simple steps, companies and consumers can cut down the usage of electricity – especially coming from burning coal or gas – to save billions
A commercial system requires 15–30 kWh of electricity to produce 1 kg of C2H4 but can reduce the carbon intensity by 20–30 % using renewable energy [43]. However, the CO2 -to- C2H4 conversion is still challenging, as C–C coupling has to compete with more favorable C–O and C–H ...
First, the CO2 emissions from the power sources is calculated: PSE=∑𝑎𝑖·𝑏𝑖PSE=∑ai·bi (1) where PSE represents the total power source emissions in gCO2/kWh, ai represents the CO2 emissions from the power source in gCO2/kWh, and bi represents the share of the particular po...
