“Solar energy – this is an opportunity to benefit from two directions, energy and the environment. On Earth, more than 2 billion people in need of this technology, which has actually competes with other energy sources. Even in cloudy countries – such as the UK, may be get all the electricity we need from solar panels installed on tall buildings. ” He said in an interview with BBC BBC Dr Jeremy Leggett of the British company Solar Century.
The sun – an inexhaustible source of energy – the world gives every second 80,000 billion kilowatt, that is several thousand times more than all the power stations in the world. Solar energy has been developed in many countries. Only in the US are operated solar collector area of 10 million. M2, which provides an annual fuel savings of up to 1.5 million. M. The sun – a source of energy is very high power. 22 days of sunshine on the total power coming to Earth are all reserves of fossil fuels on Earth.
In order to evaluate solar energy rounded believe that the flux of solar radiation outside the Earth’s atmosphere is 1.4 kW / m2, and at the level of the ocean at the equator in the afternoon of 1 kW / m2. If you appreciate the solar energy that our planet receives in one year, it will amount to 1,018 kW / h, which is about 10 times the energy of all explored and unexplored fossil fuels, including fissile material.
Solar energy is gaining a stable position in the global energy sector. The attractiveness of solar energy due to:
- Available in every point of the planet, so it is attractive for all countries;
- solar energy – an environmentally friendly source of energy;
- solar energy – an inexhaustible source of energy that will be available through thousands of years.
