おはようございます。

昨日もKhan Academyで対数について勉強しました。🤗

数学の学習を家計にも活かしています。副アカウントにもポストしましたが、最近は電気代が安くなる兆しがあります。🔋

オイルヒーターよりエアコンを優先して使うようにした結果、電力の使用量が減りました。🔌

何とかひと月に300kWh程度に抑えたいです。😙

そのためには電力使用量を削減して、1日に10kWh以内に抑えることが重要になります。🧑‍🏫

昨日はそれができました。これを一ヶ月間、続けられれば電気代は1万円以下になります。😁

エアコンが壊れないことを願います。その場合はオイルヒーターの稼動が増えることでしょう。😸

今日も頑張るぞ！😄💪🍚

Good morning.

I studied logarithms again yesterday at Khan Academy. It was interesting! 🤗

I’ve also been using my math skills to help me manage my household finances. As I mentioned on my sub-account, I've been trying to reduce the cost of my electricity bills lately.🔋

To achieve this, I've been making a conscious effort to cut back on my electricity usage. Specifically, I've been prioritizing the usage of my air conditioner over the oil heater, which has resulted in a reduction of my overall electricity usage. 🔌

My goal is to reduce my electricity usage to around 300 kWh per month, which means I need to keep my daily usage within 10 kWh. 🧑‍🏫

Yesterday, I was able to stay within this limit, and if I can maintain this for the rest of the month, my electricity bill will be under 10,000 yen! 😁

I'm a bit worried about my air conditioner breaking down, though. If that happens, I’ll need to rely more on my oil heater, which will increase my electricity usage. 😉

My house has a two-stage hybrid system, which means I can switch between different energy sources depending on my needs. 😸
