I have always wondered why hasn't there been effort to exploit sources of alternative energy. Each time oil prices reach alarming levels, there is this noise on how we should be seeking to exploit alternative energy sources thus decreasing the dependency on Fossil fuels, however, as soon as the prices get back down to seemingly acceptable levels. The issue of alternative energy is once again put on the back burner. Is it that as some people believe that the large oil producing conglomerates is having a hand in the lukewarm promotion of alternative energy production? It may not be a far-fetched notion because if alternative energy should be exploited on a large scale it would really hurt their revenues. It's time enough for greater emphasis to be placed on the exploitation of alternative because it would be better for the well-being of humanity.
