Where to take energy: looking for alternatives
• Where to take energy: looking for an alternative to
We turn on the light, inserted into the socket or that equipment, to enable that need electricity, we sit down on a bus, subway or train - all this has become commonplace, but we rarely think about what actuates it all - about energy. But in the cities we see a steaming tall chimneys, out of which is not always white smoke. Sometimes it is gray, and may even be black, and then it is worth considering here, and environmentalists.
By the way, electric transportation is called the most ecological. All this, of course, it would be so, because the products of combustion in the process of movement of the vehicle no. But these products have on the stage of generating electrical energy by means of which all the machines and move. If, however, this energy is not received by the alternative. The sun, the wind, the energy of the sea, the energy of the earth - all that energy, which can be obtained, without burning the hugest amount of coal, gas and any other fuel, without putting at risk their lives by using nuclear reactors. Everything can be much safer.
In the developed world for a long time to implement similar projects. Solar Spain receives more than half of its energy from the sun, putting solar panels and collectors. On this same path was Germany, the Scandinavian countries are the same way. Of course, at the initial stage, all this will require investments and investments. Buy one powerful solar panel - the pleasure is not cheap. In addition, the payback period can be 10 years. But this concern about the future, about the environment, security.
In general, renewable energy sources, even the title suggests that as long as the sun shines and the wind blows, we will not be left without power. Different countries may use different non-traditional sources, because of the differences of its climate and geographical position. If this is the north, where quite cold, but a lot of powerful wind power, particularly in coastal areas - wind power is just what you need! There are nuances. For example, in the Sahara desert, where a lot of sun, you can not put a solar collector as there is a lot of sand, and there is a problem of clogging their solar installation. But in Spain or Portugal - it goes with a bang.
The introduction of such ideas and projects very disadvantageous monopolists. Gas and oil, which are used to get super-profits for the fact that no one but them can not provide states and their peoples in this essential fuel. Oil and gas industry, too, does not stand still, we hear more and more about shale gas, when the country where he is found, he suddenly turned from an importer to a gas exporter. Recall the US here. To get the angle by the upper layers, it is necessary to delve further, more than one kilometer, and is even more increases the risk for those who have this useful stone produces.
Nuclear power plants - yes, it is quite cheap. That is, to build a new reactor is very expensive, but then the cost of the generated energy will be cheap. But how many of the potential risk! Like sitting on a powder keg. Even in high-tech and advanced case of Japan on nuclear issues. The question, of course, debatable, but some EU countries refuse to from this for the benefit of alternative sources. Carried out at referendums ask their peoples. The former Soviet Union, few people who have something to ask, especially from the people. But people should exhibit an alternative search requirements. It is said that the money - the circulatory system of the economy and the energy industry. It can be a long time to burn coal and gas, to produce oil, as long as it's all there. But now you need to think about the future, to someday not have to face the prospect of "doomsday" in the literal sense of the word.
