Jigsaw – the other energy of the sun

The Almeria Solar PlatformThe most important public research and development center specializing in focusing solar energy on the planet, began to see the light of day in the late 1970s. It will appear, starting in the mid-1980s, the first great generation of Spanish researchers from solar thermal energy. The second generation, the second wave, is coming now.

Based on the Thermal solar energyin Spain in 2021 more than 115 megawatts thermal (MW); Which resulted in us exceeding 3.4 gigawatts of accumulated power; More than 118,000 housing projects have been closed, and another 91,000 have been completed. Solar thermal energy also provides public assistance to the residential and services sector, small and medium-sized businesses, and public bodies. According to one of the largest manufacturers in the sector, Junkers BushIt can cover up to 70% of the needs of a home in Spain, thanks to 3,000 hours of sunlight.

In the world, after seven years of decline, solar thermal capacity grew again in 2021, by 3% to be exact, with Italy, Brazil and the United States as great heroes. In Italy it grew by at least 83%, in Brazil 29% and in the United States 19%. This is data from the Solar Heat Worldwide 2022 report, just published by the International Energy Agency.

Industry sea ​​wind Global signed 2021 the best year in its entire history, with a record: 21100 MW of new energy installed. The data has just been released by the Global Wind Energy Council (GWEC), which published its 2022 Offshore Wind Report at the United Nations Ocean Conference just hosted in Lisbon.

A few days ago, the presidents of Gesternova and Caja Rural de Jaén signed an agreement to promote the development of photovoltaic solar installations, both individual and collective, thus promoting self-consumption, savings and efficiency. This is one of the last shows Gesternovaa leading company in the marketing of renewable energy exclusively in Spain, which chairs Jose Maria Gonzalez Velez, is as familiar as few with the energy sector and the changes it has undergone in recent years. “We are subsidizing energy for the French,” he says.

The hydraulics It is the electricity generation technology that has set the price most of the time in the Spanish wholesale market in the last three years. According to the National Energy Commission, large consuming hydroelectric plants generate electricity for less than 10 euros per mega. But megawatt-hours reach astronomical prices: 300, 400, 500, 600 euros and … up to 700. Pumping hydraulics holds the record. It was he who fixed it Highest price on the most expensive day From date (March 8): 700 € at 8:00 pm.

Ocean Energy in EuropeThe European Ocean Energy Association presented its annual report for 2021 a few weeks ago, highlighting the desire of three countries to lead the global race in these technologies. The United States (which in 2021 budgeted $200 million to aid the sector), the United Kingdom (which called for an auction with special support for tidal force) and … Spain, which plans to allocate 200 million euros until 2023 to bolster powerful test platforms Already for new marine technologies.

Although some of this hydrogen It may be new to them, the fact is that its multiple applications as an energy carrier have been known for decades. s And – the cell A good example of that. Since its establishment in 2001, it has become one of the leading international events in the hydrogen and fuel cell industry. Next date will be Stuttgart (Germany) on October 4 and 5, 2022. An ideal opportunity to learn about technological developments and markets that are now growing strongly around the world.

Only last year Rollwind It has doubled its workforce, expanded its network of technicians across the peninsula, signed major agreements with important multinationals, including Matrix, RWE and Ørsted, and continues to add new renewable projects, including eco-friendly properties. In addition, it is worth highlighting the new side of the company, since now it not only develops projects, but also manages them as property.

In the full growth of renewable energies around the world, bulhof Become a reliable partner to face all challenges. Because in addition to standard parts and mounting elements developed to measure, Böllhoff has comprehensive mounting systems of the highest quality, adapting to any requirements of both solar panels and wind turbines.
