Electric Showers -

Quote from Website:

"In Brazil, electric showers are the main way of heating water in the residential market. According to the federal electric company, Eletrobras, electric showers are installed in more than 67 per cent of homes, and account for between six and eight per cent of Brazil’s total electricity consumption. It only costs around US$10 to install an electric shower heater in a home, but this then necessitates an investment of around US$900 in electricity generation and distribution. One reason for this expense is that water heaters are used primarily during peak hours, and this affects generation capacity requirements and transmission and distribution infrastructure. The use of electric showers is responsible for more than 18 per cent of Brazil’s national electricity demand during peak hours."

This ties in with show 78 on HVDC:

See page 2 & 10 of this report about HVDC and Itaipu:

Quote from World Bank PDF:

"• In Itaipu, Brazil, HVDC was chosen to supply 50Hz power into a 60 Hz system; and to
economically transmit large amount of hydro power (6300 MW) over large distances (800
km) "
