This WordPress blog (and also ownCloud) is running on my new RaspberryPi 2! Awesome for this price and the power consumtion is very low (<15W inclusive my router) measure by a simple electric socket wattmeter. That means in Euros:
15W * 24h * 365d / 1000 = 131.4kWh 131.4kWh * 0.18€ = 23.65€/year
I’m going to try it out and see how long the RaspberryPi will work. If there are any problems I will give an update about my experiences.
See my RaspberryPi section if you want to build your own small and userfriendly webserver!
