Nobody likes coal. As such the Danes certainly have good reason to exploit more wind power. In Canada we already generate 60 percent of our electricity from renewable hydro. But we would need about 760,000 wind turbines, each rated at 1.5 Megawatts and standing 300 feet tall, located offshore in the Gulf of St. Lawrence, to eliminate our need for non-renewable power generation. Reduction is really the only solution (besides greater nuclear power), and non-renewables being what they are, are inevitably doomed, so reduction will happen eventually.

The big problem is transportation, where reduction in the size of vehicles will introduce safety issues. I think the answer in the short term are vehicles that can run on multiple fuels interchangeably. For example, a company called US Carburetion sells do-it-yourself kits that will allow your car to burn gasoline, propane, or compressed natural gas interchangeably without any further modification. These are all fossil fuels, but it is not hard to modify an engine to run on ethanol (homebrew alcohol), and a diesel engine will burn biodiesel (vegatable oil) without modification. Even though Ford originally made engines to burn both gasoline and ethanol, the former became dominant because of cold-weather start capability and higher energy density. Currently fossil fuels are still abundant, but that could change anytime in the next 20 years, so IMO engines that can burn multiple fuels would be an good thing.
