Instant electric shower cost: super expensive

In Brazil there are about 60 million instant electric showers. The reason is simple: the purchase cost is the cheapest. Less than USD 10.

But it is the most expensive on the planet when it comes to the real cost of the energy consumed.

* Investments in generation, transmission and distribution in the electricity sector is USD 2 thousand/kW
* The monthly amortization of this investment is USD 25/kW/month
* The typical shower is a 5 kW unit
* Monthly amortization will then be USD 125/month
* The average Brazilian house consumes 170kWh/month of electricity
* 40 kWh of this consumption is originated by the electric shower
* The monthly amortization of USD 125/month referred to the consumption of 40 kWh is USD 3/kWh
* The tariff charged by the concessionaires is less than USD 0.2/kWh

It is equivalent to saying that the difference is paid by all of us under other titles. This is an important amount, measured in billions per year, given the number of showers installed.

We need to go for real economical solutions. Competitive final cost.
