Now there are a large number of various methods of gaining the energy. Some of them are environmental friendly. nevertheless some are constantly polluting our planet, but they are not expensive and well-known. People have been providing energy for their flats, vehicles and industry from the Earth natural resources like coal, oil, gas, sun, wind, water energy and from artificial sources like nuclear power plants. Each and every of those methods have got their advantages and bad sites.
Coal and oil are very popular, nevertheless they pollute our planet, besides after some period of time they will be ended. Gas is cheap and lots of of today’s vehicles have got it instead usual petrol, nevertheless it must be provided from far away in pipes and it is highly explosive, which endanger its users. Photovoltaic power stations are taking the energy from the sun,
which means that they don’t pollute the nature, however they can be dangerous for birds (they lose they air path when they are flying upon these sort of stations) and, what is important for people who have given the money, photovoltaic power stations are not cheap. Wind farms are very effective and popular, especially in China, however the wind power equipment is expensive and they take a lot of space.
Hydropower doesn’t pollute the environment, nevertheless it may disorder natural develop of the river’s creatures and the water power plants must be well designed to make possible the water transport (including ships and ship equipment). Nuclear power plants are very effective, however they are very dangerous (all of us have in memory the tragic accident in nuclear power plant in Chernobyl in Ukraine), after leak from some oil firm we have an oil stain we could see it and we can provide some actions to fix it, but first of all we have knowledge about where it is, unfortunately radiation is invisible, it you can’t smell it and what is the most dangerous it is active thousands of years.
The best way of gaining the green energy is water power plants, which give energy and give a possibility to transport lots of things (even large units with ship equipment can be transported in this way), big wind farms (where the wind power equipment is used to built giant fields of pure energy – one of the best producers is the Republic of Poland) and an energy from the sun (today even cars may be charge in this sort of way).
It is very important to look for various Methods of gaining natural energy. The decision in what world we are going to live in the nearest future belong to us.
