In today’s realities of growing global energy issues the question of transition to alternative energy sources becomes increasingly relevant. Orientation, which takes place in the direction of oil, gas and nuclear energy could lead certain countries to a serious energy dependence on the world’s largest suppliers to these sectors of energy and now threatens the economic security of many countries. It is clear that all the energy problems will not be solved by alternative sources of energy in the coming years. But focusing on them gives a real opportunity to strengthen position of a state in the future, to increase state’s energy security.

For instance, the following statistics confirms the world trend emphasis shifting in the way of alternative energy. In 2007, investments in such energy made more than 100 billion U.S. dollars all over the world. And according to the experts, the global volume of electricity generated by renewable sources reached the level of 240 GWh. These figures correspond to 50 percentage growth of alternative energy in comparison with the data in 2004. Alternative energy sources make from 4 to 8 percent of total world energy market under the various estimates today.

International Energy Agency believes that the world energy obtained from sun, wind, water, earth’s warm, as well as biomass will increase twice in comparison to 2009 till 2030. It will make 16 percent of the total world energy production. The European Union of industry of renewable energy estimates the situation even more optimistic. From its point of view, the share of alternative energy will rise to 35 percent by 2030. The European Commission believes that one fifth of the energy will be produced from environmentally friendly sources in 2020 in Europe. In Germany, as one of the most focused on alternative sources of energy countries, the share of renewable energy may reach 40 percent and about 67 percent in the production of electricity, – according to the data of federal union of renewable energy.

Nowadays, solar energy is one of the most visible among alternative sources of energy. In addition, the energy sector is one of the most rapidly growing, encouraging professionals to give him special attention. Experts estimate that the global solar cell market is growing by more than 30 percent annually. According to information released by the European Association of photovoltaic industry in the European Union, under favorable conditions, volume of electricity produced by converting of solar energy, may exceed the certain indicator of 2006 by more than three times till 2010.

What is the popularity of solar energy due to? Firstly, the solar energy is available in any place of our planet having different flux density radiation not more than twice. Therefore, it is attractive to all countries, responding to their interests in terms of energy independence. Secondly, the solar energy is a clean source that allows to increase using of it without increasing the negative impact on the environment. In addition, solar energy – is approximately inexhaustible energy source that will be available to humanity in millions of years.

It is known that the concept of solar energy means using of the available almost anywhere in the world of solar radiation energy through its conversion into electricity or heat. And in the first case, the transformation uses the photoelectric effect, which occurs in specialized semiconductor devices – photovoltaic cells. And crystalline silicon photo converters for land application have become the most common. They make more than 90% of the world market nowadays.

Modern solar energy “employs” many companies that produce metallurgical silicon, grow monocrystalline or multicristal ingots, cut them into plates, fabricate photovoltaic cells on the basis of these plates and assemble transducers into solar modules. They are further installed in various types of target systems –both into small, designed to provide an electric current of small loads such as lights, parking machines, telephones or water pumps and to large solar power plants, which generate electricity for mass consumption.

The uniqueness of solar energy lies upon its immense promise. There is no secret that many major capitals have formed due to the oil and gas decades ago, that is to say the so-called traditional sources of energy. Just as it is no secret that the reserves of traditional energy sources over the years are being depleted, and prices for them are growing respectively. And in a certain number of years, mankind shall face the fact that oil and gas would have come to an end. Therefore, many states and large corporations are puzzled by looking for the reasonable alternatives. One of the main alternatives is the use of solar energy.

Looking back for 10 years ago today, we can see an incredible trend of growth in electricity consumption produced by converting the sun light into electric current by 25-30% annually. And, despite all the crises and turmoil in world markets, this trend keeps on and will keep on during at least the next 25-30 years.

What does this mean? I think that in 10-20 years, solar power together with the use of wind energy and biomass will become a new oil and gas of 21st century. Of course, I may make a mistake in their assessments on terms, but still it would not be the very big mistake. And the capital will be made on such a business in the future – it is the prospect for alternative energy. And we are not talking about any “next bubble” here. So, only people who are utterly unfamiliar with the topic and try to earn cheap popularity at its position can speak in such a way.

The life shows that in order to participate in the “solar” pie sharing tomorrow we must begin to bake today. The situation says that the threshold of entry into the market of solar energy is still not very high and a large number of potential markets are still not covered by the proposals. The current level of prices still can get reasonable payback periods of “solar” projects, even of small scale. Although we can say that the trend of the electricity cost reducing generated from alternative sources maintains and it will be equal to the cost of conventional electricity very soon. And then you can recoup only the very large projects that require huge investments. And despite the attractiveness the market entry threshold would be too high for most of potential players.

It is a real gift that we live in the times when the ruling elites start to understand the value of living in harmony with the nature on this planet. And solar power grants is a realistic proof of it.

The world will have to end dependence on fossil fuels and reduce emissions of greenhouse gases dramatically in the nearest few decades. In case of success, five technologies will change the energy picture of the world radically.

Scientists suggested producing solar energy in space, in the place the sun always shines, more than three decades ago. If you put giant solar collectors onto orbit around the Earth, they will be able to supply electricity to any place in the world non-stop. The idea is that sunlight is reflected from the giant orbital mirrors, being accumulated in the numerous photovoltaic cells. Then, light has to be converted into electricity, and then – in the microwave rays that are directed toward the Earth. Antennas placed on the Earth’s surface capture the microwave energy and convert it back into electricity.

Technology makes you think about science fiction but is actually very simple. The solar collectors in orbit located approximately 30 000 kilometres from the Earth emit energy in the form of safe microwave rays. An earth mile diameter station host of microwave emanation would make about 1 000 megawatts of energy, which will be enough to power more than one million households.

The cost of solar panels sending into space is the biggest challenge, as it is necessary to design a system of very light weight, so it took only a few launches.

Vvehicles’` transfer to the electricity could reduce oil consumption and clean the air. But it can be real only if the energy used by electric cars is obtained from the atom, wind or other clean sources. The second question concerns to the battery capacity.

In the lithium-oxygen batteries, oxygen goes through the carbon cathode and having united with lithium ions from a lithium metal anode using the electrolyte produces an electrical charge. Such catalyst as manganese oxide helps the reactions to be conducted.
Lithium-ion batteries, commonly used in laptops, are already being used in hybrids and next-generation electric vehicles. They are more powerful than other batteries for cars, but are very expensive.
.
As an alternative a lithium-oxygen battery may be. Its performance is ten times more than the performance of lithium-ion batteries and is comparable with the performance of gasoline running engines.

The wind and the sun are inexhaustible sources of energy, but the energy generated by them must be spent immediately on the spot yet. Moreover, these energy sources are unstable The question is how to accumulate and store the energy produced by them.

Rechargeable batteries can save electricity from the windmill or solar panels, and deliver it when the sun does not shine or the wind does not blow. A promising idea is the use of lithium-ion technology for energy storage. Currently, researchers are exploring new materials to improve performance and capacity of batteries and reduce their price.

Scientists also consider the experimental technologies that will limit carbon dioxide emissions from coal-fired power plants by 90% while limiting the growth of expenditures.
