Now there are a large number of different ways of obtaining the energy. Some of them are called the green energy. nevertheless some are still polluting our world, but they are cheap and tested. People have been providing energy for their flats, vehicles and industry from the Earth natural resources like coal, oil, gas, sun energy, wind, water and from artificial sources like nuclear power plants. Every of those methods have their advantages and disadvantages.
Coal and oil are very common, however they pollute environment, besides after some time they going to be ended. Gas is not expensive and lots of of modern vehicles have it instead ordinary petrol, but it have to be provided from far away in pipes and it is strongly explosive, which endanger people. Photovoltaic power stations are environmental friendly,
which is clearly that they don’t pollute environment, however they may be deathful for birds (they mislay they air path when they are flying upon these sort of stations) and, what is important for the investors, photovoltaic power stations are very expensive. Wind farms are effective and common, especially in China, but the wind power equipment is expensive and they need a lot of space.
Hydropower doesn’t pollute the environment, but it can disorder natural icrease of the river’s creatures and the water power plants need to be well made to make possible the water transport (including vessels and ship equipment). Nuclear power plants are increadibly effective, however they are highly dangerous (we all have in minds the tragic accident in nuclear power plant in Chernobyl in Ukraine), after leak from some oil company we have an oil stain we could see it and we may provide some actions to stop it, but first of all we have knowledge about where it is, unfortunately radiation is invisible, it doesn’t have smell and what is the most dangerous it is active thousands of years.
The best way of gaining the pure energy is water power plants, which give energy and create a possibility to transport many things (even very big units with ship equipment may be transported by this method), large wind farms (where the wind power equipment is used to construct giant fields of pure energy – one of the best producers is Poland) and an energy from the sun (nowadays even cars can be charge in this sort of way).
It is very important to look for different Methods of gaining natural energy. The decision in what world we are going to live in the future belong to us.
