Now there are a lot of various ways of obtaining the energy. Some of them are environmental friendly. but some are still polluting our world, but they are cheap and tested. People have been taking energy for their homes, cars and industry from the Earth natural resources such as coal, other fossil fuels, gas, sun energy, wind, water and from artificial sources such as nuclear power plants. Each and every of those ways have got their advantages and bad sites.
Coal and oil are very common, but they pollute the Earth, apart from that after some period of time they going to be ended. Gas is cheap and lots of of present machines have got it instead usual petrol, but it must be provided from long distances in pipes and it is highly explosive, which make it dangerous people. Photovoltaic power stations are environmental friendly,
which is clearly that they don’t pollute the nature, however they can be deathful for birds (they mislay they way when they are present upon these kind of locations) and, what is important for the investors, photovoltaic power stations are very expensive. Wind farms are effective and popular, specially in China, however the wind power equipment is costly and they take a lot of space.
Hydropower doesn’t pollute the environment, but it can disorder natural develop of the river’s animals and the water power plants need to be well planned to make possible the water transportation (including ships and ship equipment). Nuclear power plants are increadibly effective, but they are very dangerous (we all have in minds the terrifying explosion in nuclear power plant in Chernobyl north Ukraine), after leak from some oil company we have got an oil stain we could see it and we may implement some actions to stop it, nevertheless first of all we have knowledge about where it is, unfortunately radiation is unseen, it doesn’t have smell and what is the worst thing it is in our surrounding for thousands of years.
The most effective way of gaining the pure power is water power plants, which gain energy and give a possibility to transport lots of things (even large units with ship equipment may be transported in this way), big wind farms (where the wind power equipment is used to construct large fields of pure energy – one of the greatest producers is the Republic of Poland) and an energy from the sun (today even vehicles can be charge in this kind of way).
It is very important to search new Methods of gaining natural energy. The decision in what planet we are going to exist in the nearest future belong to us.
