The offshore power plant or wave farm at Mutriku is the only commercial facility (it is not a prototype) in the world that operates by regularly feeding the grid with electrical power produced by waves. It has been operating since 2011 and the study by the UPV/EHU's EOLO group analysed its behaviour during the
Soft X-rays excite the core level electrons, leading to the emission of photoelectrons from various atoms, whose waves are then scattered by the surrounding atoms. The interference pattern between the scattered and direct photoelectron waves creates the photoelectron hologram, which may then be captured with an electron analyzer.

This is a thermal image of a Basque Country building in the 70s, where heat loss is evidenced due to lack of insulation.
Over the coming years there is a legal commitment for all the countries of Europe to improve the energy efficiency of buildings, which boils down to constructing nearly zero-energy buildings (nZEBs), in other words, buildings that consume the minimum of energy. The EU Directive 31/2010 establishes two key deadlines:
A floatovoltaic installation at Far Niente Winery in Oakville, Calif., comprises nearly 1,000 solar panels floating on pontoons on the vineyard irrigation pond.
RIVERSIDE, Calif . -- There's a tradeoff when sprawling solar farms pop up on agricultural land: farmland disappears, perhaps forever, in return for growth in the promising renewable energy sector.
But what if large solar installations could be built
As the world tries to combat climate change, sustainable forms of energy are on the rise. Solar energy is of particular interest, but arrays of photovoltaic panels take up a lot of space and can compete for prime food-producing land.

Deep eutectic solvents used as the medium of sensitizer and emitter chromophores (left) and the photon upconverter developed (right). The sample converts low-intensity (a few mW) green light into clear blue emission and demonstrates high thermal stability during exposure to a burner flame for 1 min.
The conversion of solar energy into electricity is currently restricted by a concept known as the Shockley-Quesser limit. This limitation allows only photons that have higher energies than those of the bandgap to be used, while those with lower energies are wasted. In an effort to obtain a solution to this problem
After dissolving plant biomass by the novel solvent, carboxylate-type liquid zwitterion, hydrolysis and fermentation were consecutively carried out in one reaction pot for conversion into ethanol.
The first-generation biofuel, industrialized, ethanol, is produced from foodstuffs like maize, and thus poses great concern about a possible future shortage of food. It is therefore necessary to produce ethanol from non-food biomass like weeds, waste paper, paper cup, etc. (second-generation biofuel ethanol).
