The U.S. is not self sufficient at current production. The U.S. produces almost 9 million barrels a day and uses almost 19 million. The U.S. could be self sufficient but the permit restrictions on shallow water drilling as well as other political issues make self sufficiency a ways off. As far as Europe and renewables, I think the perception is far more positive than the reality. Windmills and solar provide a very small part of Europe's energy. Russian natural gas is by far the most important energy source. France has had good luck with nuclear but the anti-nuke crowd is rather robust, limiting expansion.
US production for the 3rd quarter of 2014 was over 14 million barrels a day (the most recent quarter I saw numbers for, see my EIA link in another comment).
Indeed. Europe is still heavily reliant on coal and petroleum. Anti-nuclear crowd is incredibly robust and they are limiting expansion in numerous places. Windmills, solar and hydro are not capable of replacing fossil fuels without the help of nuclear, unless we want to cover all of Europe in windmills and solar panels.
But we are moving in the right direction, but Europe is not doing as well as we like to pretend.
