This fuss at stock exchange has already bothered us. Oil has again fallen below 50 dollars for barrel. Oil has fallen because the USA increases stocks of oil during low demand for hydrocarbons in the conditions of crisis. Still one year ago the price for one barrel was 147$. Less than for a year oil has fallen in price in 3 times. Today futures for May are being sold for 49,52$ and under forecasts the price will continue to fall. Falling in the oil price is explained by global world crisis. In the conditions of crisis many people began to spend less money on gasoline. And oil extraction remained at old level for some time. In this connection OPEC (The Organization of the Petroleum Exporting Countries) have taken the decision on partial reduction of volume of an oil extraction. But as we see, the prices all the same do not rise to the former level. Certainly l it is reflected in economy of all world. It turns out we are in a vicious circle. But on the other hand now electromobiles are actively propagandized. And it will positively affect ecology of our planet.
