Do Scandinavian people have electricity or technology?
Yes, for instance they were responsible for one of the most successful phone companies, Noikia.
Also Scandinavia is very well served by hydroelectric power.
Technology can indeed save money. An electricity monitor is a good example. It is able to tell you how much electricity a given appliance is using. When used with a computer monitor, it will be able to tell you how much electricity you are saving by powering the monitor off completely instead of leaving it on standby. When you save electricity, you save money.
