China has a coal-fired energy system equal to more than 13 times our entire electricity generation. Between now and 2020 it is going to add between 400GW and 500GW to its existing 670GW of coal-fired power generation. That’s net. So if they close say 200GW of really dirty old stations they will be building 600GW to 700GW of new ones all pumping out carbon emissions.
Total power generation in Australia is about 50GW.
China might be aiming for 150GW of wind and 20GW of solar by 2020 installed capacity. Because the wind won’t always blow and the sun won’t always shine real capacity of the two combined will be closer to 50GW by 2020 as against an extra 400GW at least of additional coal-fired generation.
By 2020 China will be emitting about 25 times the entire emissions of Australia today.
