Not actually during the war, but before the war, yes. During the 1930s, Hitler was the darling of industrial and banking leaders in the US and Britain because they were sure he was going to keep Europe from going Communist. President Bush's grandfather had several joint ventures with Nazi-owned companies--banks, steel mills, wire drawing factories, etc. After the beginning of WWII, the US govt. no longer allowed them to do this.
During WWII we had plenty of gas because we drilled and refined it here, while Germany, who had to import all its gas, had shortages. In fact we rationed gas in the US not because of a shortage but a shortage of rubber for tires, because the Japanese held all the islands in Southeast Asia where we got most of our rubber in those days.
Germany's energy shortage played a large part in their losing the war. For instance, Hitler had the first jet fighters, the Messerschmidt ME-262, which was the fastest in the world at the time, but he couldn't use them because they used much more fuel, so he decided not to make very many.
