Sorry, but this article is mostly nonsense. We will not "run out" of oil because the economics of it simply don't work like that.

It's supply and demand, just like anything else. When the oil is less plentiful it will be more costly to extract. In other words, when the easy oil is harder to find then they will start extracting the stuff that's more difficult. This is why the Canadian Tar Sands are not viable unless the price of oil is something like $80 a barrel, which it is not currently.

The price will rise due to higher extraction costs. As oil becomes more and more difficult to find and extract the price will continue to rise. A rising price will make alternatives such as solar much more attractive. When people start to demand alternatives, then it follows that more money will be spent on companies to do research and development.

Bottom line: Alternative energy sources will replace fossil fuels slowly over many years, while the price of fossil fuels slowly climbs due to supply and demand. We have plenty of oil left and it's a superior form of energy to anything else, which is why we continue to use it. Solar and wind are practically useless to power our world at this point in time. Please stop spreading fud.
