A combination of renewable and conservation. Conservation is by far, the most economical solution. The energy necessary per person for a decent life – including heating and cooling, domestic services, transport, and industry, – is equivalent to a 1 kw device “on” all the time (or about 8600 kwh per person and per year) Canada per capita energy consumption – the highest in the world – is 425 GJ/p.a or 118,000 Kwh/p.a (equivalent to a 13 kw electric device “on” all the time ) and about 2.5 times higher than European. The challenge for Canadians is hence to reduce our energ consumption by a factor 12.
