Residential Photovoltaic Systems in US, Germany, UK, France, Brazil, Mexico
The average American household electricity consumption amounts to almost 12,000 Kwh per year.
That’s a lot more than the average consumption in other countries: Australia: 7,200 kWh/year, France: 6,300 kWh/year; UK: 4,600 kWh/year; Germany: 3,500 kWh/year; Brazil and Mexico: 1,800 kWh/year (Source: World Energy Council).
A 4 kW or a 5 kW electric photovoltaic (PV) system can meet all or most of the electricity needs of many homes in countries such as France, UK or Germany (not to talk of Brazil or Mexico), but not in the US or Canada.
How to solve this North-American problem?
The answer: Energy-efficient domestic appliances and electronics, energy efficiency lighting, high levels of home insulation and air-tightness, energy efficient windows… We need to cut residential energy consumption by half or more. And that’s not impossible or difficult, in new construction.
