Nowadays there are a large number of different ways of obtaining the energy. Some of them are called the green energy. however some are constantly polluting our world, but they are not expensive and tested. People have been providing energy for their apartments, cars and industry from our planet natural resources like coal, other fossil fuels, gas, sun energy, wind, water and from artificial sources like nuclear power plants. Every of those methods have got their good sites and bad sites.

Coal and oil are very common, but they pollute the Earth, apart from that after some time they will be ended. Gas is cheap and lots of of modern vehicles have it instead normal petrol, however it have to be delivered from long distances 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, but they can be deathful for birds (they lose they air path when they are present upon these sort of places) and, what is significant for the investors, photovoltaic power stations are not cheap. Wind farms are effective and popular, specially in China, however the wind power equipment is costly and they need a lot of place.

Hydropower doesn’t pollute our planet, nevertheless it can disorder natural develop of the river’s animals and the water power plants have to be well planned to give an opportunity for the water transportation (including ships and ship equipment). Nuclear power plants are very effective, nevertheless they are highly dangerous (all of us have in memory the terrifying accident in nuclear power plant in Chernobyl in Ukraine), after leak from some oil firm we have got an oil stain we can see it and we may provide some actions to stop it, nevertheless first of all we know where it is, but radiation is unseen, it you can’t smell it and what is the worst thing it is active thousands of years.

The best way of gaining the green power is water power plants, which gain energy and create a possibility to transport lots of 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 built large fields of pure energy – one of the greatest producers is the Republic of Poland) and an energy from the sun (nowadays even vehicles may be charge in this sort of way).

It is significant to look for new ways of gaining natural energy. The decision in what world we are going to live in the nearest future belong to us.
