Adjust CO2 emissions
The current co2 emissions calculation assumes the following (https://monitor.crownplatform.com/?p=co2)
*Power consumption per node = 36 Watts Cost per kWh = $0.19 CO2 generated per MWh = 346 kg
We assume the worst possible case where all the power is generated in coal-fired powerstations. The figure of 346 kg per MWh comes from Intergovernmental Panel on Climate Change (IPCC). Guidelines for National Greenhouse Gas Inventories (2006).*
According to new data requested to VPS service providers, it can be stated that
-
Power source: servers located in US / Europe will never come from fossil energy and either come from nuclear or renewable energies. Since fossil source of energy drops, the CO2 generated per Mwh could be lower than 346kg.
-
The figure of 36 Watts and the cost is calculated through the monthly cost of VPS (at $5 in the current calculation). I propose a calculation of $1.5 per month for Systemnodes and $3 per month for Masternodes, since now many users do not rent VPS but only tha ability to host a node without direct access to server. This shift needs to be taken into consideration as it uses spare server resources becoming even more efficient.
In order to calculate the new emissions, the suggested price will need to be adapted. I am not sure if the 346 kg per Mwh figure refers to electricity produced with fossil energy sources and can also be lowered with the nuclear/renewable energies information.
