Gabriel Ibarra in his office at the university. On the computer a picture of Mutriku.
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

Wind turbines supply renewable energy to microgrids across Alaska.
WASHINGTON, D.C., December 26, 2017 -- The electrical grid in the contiguous United States is a behemoth of interconnected systems. If one section fails or is sabotaged, millions of citizens could be without power. Remote villages in Alaska provide an example of how safeguards could build resilience into a larger

Argonne scientists and their collaborators have used a new and counterintuitive approach to balance three important factors -- activity, stability and conductivity -- in a new catalyst designed for splitting water.
Balance forms the foundation for a happy life or a healthy diet. For scientists working to design new catalysts to create renewable energy, balancing different materials and their properties is equally important. (Catalysts help accelerate chemical reactions.)
In a new study, researchers from the

Croton nuts are the source of an oil that can power generators, water pumps and other internal combustion engines and, with processing, can be used in place of diesel fuel in cars and trucks.
Small-holder farmers in Kenya have the capacity and desire to play a major role in the scale-up of biofuel production from agroforestry, according to a Penn State forest economist, who led a study in the East African country.

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:

Mini coal-fired CHP plant on the basis of synthesis gas generator (CO + H2) and electrochemical current generator (experiment/factory).
Bituminous coal comprises over 90% of organic fuels in the lithosphere of the Earth. By burning coal and other fossil fuels one can get electrical power (which is mainly happening at HPPs). However, the existing generation methods are not efficient, bad for the environment, and extremely resource-demanding (i.e.

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).
