The CleanTechnica article is hypothetical and unrealistic, but the EIA projections are for domestic production, which is a different matter altogether. Peak oil is a demand-side (not supply-side) issue now. I can't seem to find anything reported within the past year, but I'm pretty sure that domestic demand has basically been stagnant this decade.
That said, investment in oil & gas infrastructure is in decline. Many investors are reducing their investment in oil & gas companies (in some cases completely divesting though that's for good PR to some extent).
