In order to maintain the sustainable development of civilization, further technical progress can not occur at the expense of increasing production and consumption of electric energy from renewable sources, which are gradually depleted, and are a disproportionate burden on the environment. Perhaps, the entire world understands that the use of renewable energy sources is the only possible way of the development of civilization.
Photovoltaic sources contribute significantly to the protection of climate and the environment. Electricity produced by solar sources is environmentally clean, friendly and produces no waste.
The amount of solar energy hitting the earth´s surface is so huge that it would cover the current consumption equal to 6000 times the amount of the energy that we currently use - Earth surface is hit by 89 petawats while our consumption is 15 terawats. Solar energy has also the highest power density (global average is 170 W/m2) among all known sources of renewable energy.
Reliable technology ensures long life.
Photovoltaic systems require little maintenance after installation. Operating costs are therefore extremely small in comparison with existing technologies.
Other benefits
With a high promotional activities guaranteed by the state, the return on investment in solar power plants is very fast.
If the photovoltaic system is connected to the power network, the energy can be consumed locally and thus reduce the total loss in the distribution system.
Photovoltaic systems can show proprietor´s responsibility to society and a proactive approach to the environmntal protection.
More intensive use of solar energy allows countries to get greater political and economic independence.
Unbridled exploitation of natural resources results in wars, conflicts, oppression and poverty in affected countries. Therefore, we should consider whether wider use of solar energy will not create more fair and stable conditions in the affected countries.
