Renewable energies are in the sights of many politicians. Concern for the environment has grown in recent times among the world's population, But experts are optimistic: the use of clean energy will increase in the coming years (Especially it is countries like China and India).
The International Energy Agency (IEA) foresees that renewable energies will continue being the fastest growing source of electricity generation in the next five years, going from representing 23% of the generation in 2015 to a 28% in 2021.
Last February, during the presentation of the IEA study 'Medium-Term Renewable Energy Market Report 2016' organized by the Spanish Energy Club (Enerclub), the head of the renewable energy division of the international agency, Paolo Grankl, stressed that renewables will mean more than 60% of the increase in world generation of electricity in the medium term.
Likewise, the senior IEA official explained that it is expected that global renewable capacity increases by 825 gigawatts (GW), which represents 42% between the years 2015 and 2021. In addition, he indicated that it is estimated that the generation of renewables will exceed 7.600 terawatt hours (TWh) in four years, which is equivalent to the total electricity generation of United States and the European Union.
But despite these perspectives, Frankl was cautious regarding its evolution due to factors and political uncertainty, its greater integration into the systems, the need for more investment or the slow development of renewable technologies in the heat and transport sectors.
Trump will not condition
Paolo Frankl also spoke about the situation in the United States. The expert indicated that he does not believe that the choice of Donald Trump as president of the North American country it will condition the growth of renewable energies in that nation which, it is expected, will exceed the installed capacity of Europe in a period of five years.
In addition, the head of the IEA's renewables division was optimistic, noting that policies "They cannot be changed from one day to the next", so the organization anticipates that there will be no "big changes" in the coming months.
In relation to Spain, Frankl pointed out during the presentation of the report on the trends of the energy market that the future auction of renewable energies may "Cause changes" in IEA forecasts. In this way, the national market could leave the recession zone in which it has been since the last decade.
In addition, through its report, the IEA warned Poland that it should reduce its use of coal in its energy mix and change its strategy to increase sources with the lowest CO2 emissions, such as nuclear or renewables, since «Coal provides 51% of the country's energy supply, according to 2015 data. "
The largest wind turbine in the world
Wind turbines like these are responsible for increasing the world's energy capacity
Vestas has presented the update of the largest wind turbine in the world. I have no adjectives to describe how huge this turbine is. The V164, a 220 meter windmill with 38-ton, 80-meter long blades, has just focused all the attention of those interested in renewables in Denmark.
The previous turbine was capable of delivering a power of 8 MW, and thanks to the updates it is now capable of reaching up to 9 MW output under specific conditions. In its first test, the V164 was capable of generating 216.000 kWh in just 24 hours.
Not only is it the absolute record for wind power generation by a single wind turbine, but it is the clearer demonstration that ocean winds will play a key role in the energy transition that is already underway.
Enough to power a home for 66 years
According to Torben Hvid larsen, Vestas CTO:
"Our prototype has set another generation record, with 216.000 kWh produced in a 24-hour period. We are confident that this 9 MW wind turbine has proven to be market ready, and we believe it will play a key role in lowering offshore wind energy prices. "
