Nowadays we know two important
non fossil sources of energy, which would satisfy the energy claim of mankind: nuclear and
the Sun energy. Kind of energies which are used nowadays are originated from fossil
The coal, gas and oil will not
be for ever. The amount of the Sun’s energy per week is bigger than the energy of the
known coal reserve on the Earth.
According to researches the oil
reserve of the world will decrease and till 2050 we consume trillion barrels of heavy oil,
which accumulated since prehistoric ages. The conclusion is definite. And urgent! We must
develop sources of energy available as quickly as we can.
Is the energy of the Sun
practical in the distant future? The answer is yes!
The energy of the Sun is clean,
safe and given for every country. The best of it is - it’s everlasting. According to
calculations there is enough sunshine on an average house of suburb to obtain three times
as much energy as the demand of a household is. The possibility is given. We must harness
To satisfy the demands of the
future, we must develop new technologies. There are more and more investigations all over
the world. The most important attention aims at development of heat radiators which change
energy of Sun to mechanical energy - and so they produce electrical energy.
