The world’s transmission lines are believed to have dropped approximately 1.4 trillion kilowatt-hours of electricity last year. That’s around 1.2 trillion metric tons of CO2 dumped into the atmosphere. Though it is unlikely these loses can be eliminated in the near future, there are ways to reduce them.
Losses of 5-7% or so are the norm today in the United States, BC and Ontario.
According to Dave Egles’ study, the Potential for Solar Power in British Columbia: 2007 to 2025, BC’s climate is much more amenable to solar than either Germany’s or Japan’s. The average production of a PV solar array in Kamloops, for example, is 1160 kWh/kW of PV installed. Even Vancouver (1009) has much more solar potential than Tokyo (885) or Berlin (only 848). One of our readers has provided more recent data that shows the last two figures are probably too low (see comments, below), but it is obvious BC has a great deal of untapped potential.
