" The IEA report looks at changes in greenhouse gas emissions between 2018 and 2019. It finds that energy-using activities increased in 2019, but the emissions did not increase because of a variety of factors including renewable energy, energy efficiency (the second largest contributor), coal-to-gas conversions, nuclear energy, and weather. " As illustrated in the attached graph, how could you explain that weather is a factor with such contribution in keeping the same level of GHG emissions?
I suppose the answer is that because of global heating, large northern countries are consuming less fossil fuels in winter to heat home and office space.
Sure @Peter Baker
But it's either an uncontrollable factor or a bounding effect??
The report states:
"More temperate weather in key parts of the world reduced the need for coal, gas and electricity for heating and cooling, which so energy demand was over 10% lower than would have been expected from economic activity."
It also states:
"This final factor – weather – is critical to properly interpreting what first appears to be an improvement in global energy intensity in 2019. Correcting for the weather, the energy intensity improvement rate in 2019 (1.6%) was almost identical to 2018 (1.5%)."
