Will Green be the Bridging Technology?

Our planet is painstakingly waking up to the fact that petroleum will soon no longer be a major component of almost every product we use and ingest. This is because, guess what, we're close to using up all the fossil fuels we can easily extract from the ground. Scientists and researchers and big manufacturing companies are slowly investigating the use of plant materials to replace all that oil has done for us. Of course, this sounds all sweet and green, but the reality is that this experimentation should have happend a dozen years ago, at least, to begin to mitigate the affects of an energy source soon to be depleted. Yes, it's a valiant try for these chemists to begin their search for alternatives, but the fact remains that they only have a few years left to come up with long term solutions which currently use the energy of petroleum products to fuel their research.
