● Let's Gradually Change Tokyo's Summers with Your HTT!

Summers are getting hotter year by year. Last year, Tokyo saw a record number of days exceeding 35°C.

Behind this is global warming. In addition to rising temperatures, the effects of climate change, such as heavy rains and floods, are spreading to our lives.

To change this situation even slightly, "decarbonization" initiatives to reduce CO2 emissions are important. This article introduces actions that can be started easily, smartly, and affordably through Tokyo's "HTT (Reduce, Generate, Store Electricity)" initiative.

・Use Electricity Wisely! Generate & Store Edition

Do you know about Demand Response (DR)? It's an initiative to use electricity efficiently by devising ways to use it. The balance between electricity supply and demand is crucial. By adjusting electricity usage at home and in businesses according to supply conditions, such as when electricity is insufficient or in surplus, we can contribute to a stable power supply.
