You know, I recently rode my bike through some villages in Germany. Just about every house had solar panels on their roof. My parents have solar panels on their roof. They produce more electricity than they use and only need very little oil and some wood for heating in winter. And they are no exception.
Germany currently produces 20% of its energy using regenerating resources (water, sun, wind).
It's not like you have to put all the solar panels in huge parks. Just put them on roofs. My uncle works at a big company and they just put solar panels on their roofs. That company now produces more energy than they need. Solar panels are already efficient enough to usually provide more energy per area than people or businesses consume in the same area.
The next step would be to have batteries in every household, to save on energy losses during 'transportation'. Also, solar panels are getting more efficient and cheap every year.
