There is just only 1 and 3 case that CO2 emissions from electricity generation actually 1Mwh.Normal power plant not to use TDM will notice a lot of CO2 emissions released.
Only case 1 and 3 only to reduce CO2 emissions from power generation to real 1Mwh power plants that do not normally lead to TDM will notice that there are a lot of CO2 emissions.
There is only case 1 3 and only reduce emissions from electricity production CO2 1Mwh real.Normal power plant without the TDM use will notice that the release CO2 out a lot.
