As for carbon dioxide which is main cause of global warming, about 50% is exhausted by use of "electricity".
In that, there is reason for generation method why you exhaust carbon dioxide when you use "electricity".
About 80% of Japanese generation electric energy uses "fossil fuels" such as natural gas and coal, oil, and, in the case of thermal power generation, fossil fuel exhausts much carbon dioxide.
In other words, we use electricity if we use, and global warming will advance.
