Now there are a large number of different ways of gaining the energy. Many of them are called the green energy. however some are constantly polluting our world, but they are not expensive and well-known. People have been providing energy for their apartments, vehicles and industry from our planet natural resources such as coal, oil, gas, sun energy, wind, water and from unnatural sources like nuclear power plants. Each and every of those ways have got their good sites and disadvantages.
Coal and oil are very common, nevertheless they pollute environment, besides after some time they will be ended. Gas is not expensive and many of modern carrs have got it instead usual petrol, however it have to be delivered from long distances in pipes and it is highly explosive, which endanger people. Photovoltaic power stations are taking the energy from the sun,
which means that they don’t pollute environment, however they may be dangerous for birds (they lose they way when they are flying upon these sort of locations) and, what is significant for people who have given the money, photovoltaic power stations are not cheap. Wind farms are very effective and popular, specially in China, however the wind power equipment is expensive and they take a lot of space.
Hydropower doesn’t pollute our planet, but it may disorder natural develop of the river’s creatures and the water power plants need to be well designed to give an opportunity for the water transportation (including vessels and ship equipment). Nuclear power plants are increadibly effective, nevertheless they are very dangerous (we all have in memory the tragic explosion in nuclear power plant in Chernobyl north Ukraine), after leak 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 know where it is, but radiation is unseen, it you can’t smell it and what is the most dangerous it is in our surrounding for many years.
The most effective way of gaining the pure energy 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), big wind farms (where the wind power equipment is used to built giant fields of green energy – one of the greatest producers is Poland) and an energy from the sun (nowadays even vehicles can be charge in this sort of way).
It is very important to search various Methods of obtaining green energy. The decision in what world we are going to live in the nearest future belong to us.
