There has been much in the news about how electric vehicle development has been hurt by the current free fall in oil prices. Make no bones about this - the oil producing countries are really worried about their stranglehold on oil becoming irrelevant. It must be a small job for them to bring prices down for a while while they spend the money that they earned when oil hit record prices and kill the new alternative fuel businesses off completely. Once these are dead, they would literally have the rest of the world by the b@11s again until their oil runs out. This is a Trojan horse that the world's oil consumers need to look at very carefully and beware of.
Any failure to address this and we shall be back to square one in the blink of an eye.
