We choose eco-friendly electricity

Last update date September 12, 2019

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.

On the other hand, in the case of generation, "renewable energy" such as sunlight or wind power does not exhaust carbon dioxide.
Do you not do electricity to use at home for "eco-friendly electricity" made by renewable energy either?
