Greens want a radical energy change until 2020The message would be full in the sense of PEGE, if there would not be the nonsens claim to decrease the electric power usage. A personal prognosis of electric power usage.
My 5 persons household with 2 computer working places used 2006 1949 kWh electric power. It's a rented apartment. Heating and domestic warm water with gas, cooking with electric power. With this usage, it's an example for low electricity usage. But 2007 will by electric power demand increase by 15% and I am even pride about it. With 300 kWh electric power, I will drive about 6000 km electric scooter. 300 kWh more electricity, but 500 litre less Diesel, because most short distances with high consumption are replaced.
I hope to built next year a Plus energy house for my family. Heating and domestic warm water by heat pump, controlled air exchange with heat recovery. This will use 2000 kWh electricity, but save 16000 kWh natural gas.
Both cars of the family will be changed to Plug-in-Hybrid cars. I calculate for me 15.000 km in electric only mode in a plug in hybrid minivan with 20 kWh/100km, makes 3000 kWh, but 900 litre less Diesel. At the small car of my wife 7500 km a year with 12 kWh/100 km. Makes 900 kWh, but 500 litre less gasoline.
16.000 kWh less natural gas, 900 litre less Diesel, 500 litre less gasoline is my energy saving potential compared to 2006. But my electric power usage will increase from 1649 kWh to 7849 kWh. So I think any demand for less electricity usage is humbug. My future house should produce by photovoltaic 10.000 kWh per year. |
