Nowadays there are a lot of various ways of obtaining the energy. Many of them are called the green energy. nevertheless some are constantly polluting our world, but they are cheap and well-known. People have been providing energy for their houses, cars and industry from our planet natural resources like coal, other fossil fuels, gas, sun, wind, water and from unnatural sources like nuclear power plants. Every of those methods have got their good sites and disadvantages.
Coal and oil are very common, but they pollute environment, apart from that after some time they going to be exhausted. Gas is not expensive and lots of of present carrs have it instead ordinary petrol, nevertheless it have to be provided from far away in pipes and it is strongly explosive, which endanger people. Photovoltaic power stations are taking the energy from the sun,
which is clearly that they don’t pollute environment, but they can be deathful for birds (they mislay they way when they are present upon these sort of locations) and, what is significant for people who have given the money, 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 place.
Hydropower doesn’t pollute the environment, nevertheless it may disorder natural develop of the river’s animals and the water power plants need to be well planned to make possible the water transport (including vessels and ship equipment). Nuclear power plants are very effective, however they are very dangerous (we all have in memory the terrifying accident in nuclear power plant in Chernobyl north Ukraine), after spillage from some oil company we have got an oil stain we can see it and we can provide some actions to stop it, but first of all we have knowledge about where it is, but radiation is invisible, it doesn’t have smell and what is the worst thing it is active thousands of years.
The most effective way of gaining the green energy is water power plants, which give energy and create a opportunity to transport many things (even large units with ship equipment can be transported in this way), large wind farms (where the wind power equipment is used to built giant fields of pure energy – one of the greatest producers is Poland) and an energy from the sun (today even cars may be charge in this sort of way).
It is significant to search (see poland patent search) different ways of gaining natural energy. The decision in what kind of world we are going to exist in the nearest future belong to us.
