The chart shows that Europe's energy portfolio is fairly distributed among the major sources. Germany is Europe's leading industrial nation and it relies heavily on coal burning to generate electricity (34%). The government is pledged to change that situation. Wind power is the country's second largest source of electrical generation at 25%. The same cannot be said for Poland and Czech Republic where coal still predominates. A decade ago, coal burning accounted for a quarter of the continent's electrical generation. If Putin thought cutting off oil and gas to Europe would leverage the EU against Ukraine, it has turned out he miscalculated. What he has accomplished is to push Ukraine farther into the western alliance.
