Renewable energy is developing at a record pace

Last year every day in the world was set to 500 000 solar panels. In China, every costaposada two windmills. We are witnessing an unprecedented "green" revolution that will radically change the balance of power in the energy market. The rate of installation of solar panels beat all records. And this is only the beginning, because the cost of wind turbines and especially the solar panels are constantly decreasing.
Based on the latest actual data for the year 2015, experts from the International energy Agency forced to seriously reconsider the five-year forecast for the development of alternative energy in the world. The forecast for the generated power from renewable energy sources in the next five years significantly enhanced.
"We are witnessing a transformation of global energy markets influenced by renewable sources," acknowledged Executive Director of the International energy Agency, Fatih Birol (Fatih Birol). He agreed that the increase is partly due to the dramatic fall in the price of equipment for solar and wind power plants. Such prices as it is now "impossible to achieve" five years ago. So, the cost of installation of wind power plants from 2010 to 2015 fell 30%, and the cost of large solar power plants — three times.
The main sources for generating electricity are still fossil fuels such as coal and oil, but progress in the development of these archaic technologies pales in comparison with the progress in the field of solar and wind energy.
The Agency predicts a further reduction in the cost of wind turbines and solar power plants in the next five years: 15% and 25%, respectively. Apparently, it's a pretty conservative estimate. It is possible, the forecasts will again have to reconsider due to the more rapid growth of solar and wind energy. Report Medium-Term Renewable Energy Market Report to 2016 is devoted to the time period from 2015 to 2021. The forecast for this segment is revised to 13% in the upward direction. According to experts, the installed capacity for this period will be increased to 730 GW, and GW 825. This is due to the adoption of more strict legislation of the United States, China, India and Mexico.
Over the past year with a worldwide installed capacity of 153 GW in the energy sector. More than half of them are solar power plants (49 GW) and wind farms (63 GW). Commissioned more capacity than generate some of the country's "big eight" — for example, Canada.
Solar and wind farms added during the year has more power than a power plant with coal, gas and nuclear fuel. This achievement has enabled renewable resources to circumvent the coal and come out on top in the world, the growth rate of installed capacity.
"Installed capacity" in alternative energy is a rather conventional figure. The sun does not Shine round the clock, and the wind blows with variable speed in different directions. Therefore, the actual production of electricity from renewable resources are much lower than installed capacity. According to this indicator, renewables are lagging very far behind.
The generation of electricity by fuel in 2014.
Apparently, to overtake fossil fuels in generating electricity, should be set to times more power generated than it is now.
World electricity generation from 1971 to 2014 by fuel (TVT⋅CH).
According to the latest data from the International energy Agency in 2015, coal provided 39% of world generation of electricity, and all renewable sources, including hydropower, is only 23%. According to the forecast, the share of renewable sources by 2021 will rise to 28%. In this scenario, renewables will generate more than 7600 TVT⋅CH — more electricity than is generating US and EU combined.
The adoption of more strict legislation in some countries in support of renewable energy is not only with the ratification of Paris agreements in the framework of the UN Convention on climate change a year earlier than expected. It is connected with serious environmental problems in some countries. For example, due to severe air pollution in China, the country now seeks to actively promote alternative energy. Now about 40% of new renewable energy capacities in the world is China (including 50% of wind installations).
Experts warn, however, that the projected growth of alternative energy depends heavily on government support, which often varies in different countries. Intermittent nature of solar and wind energy also carries certain risks for operators.
However, in the world of energy plants by renewable sources is injected more than fossil fuels. In the European Union and the United States the installed capacity of alternative energy annually exceed the new needs of the economy. So now there is no sense to build a new TPP on coal and gas, and you can gradually close the old.
In General, although falling prices and the growth rate too impressive, but that the use of solar energy and wind really helped to achieve global environmental goals, it is necessary to make serious steps in energy and transport, according to experts of the International energy Agency. published
