The Loch Ness hydropower monster, a huge renewable storage facility

We are familiar with the Loch Ness pumped hydroelectric storage system. A project that could double Scotland's wind capacity and power 400,000 homes. Scotland is pursuing an aggressive offshore wind program that includes innovative technologies such as floating wind...

Wind energy is here: global wind capacity will increase by more than 60% by 2024

Wind farm in Germany. Image: Rudmer Zwerver ShutterstockNew updated data on global wind capacity, gathered in new WoodMac study, predicts annual capacity increases of 71 GW from 2019-2023 and 76 GW until 2028. Global wind capacity will increase by 60% over the next...

Elisa, the first offshore wind turbine in Spain

Spain's first offshore wind turbine was installed in Gran Canaria. A fixed foundation wind turbine built as part of the ELICAN project. It incorporates a Siemens Gamesa 5 MW turbine. ELISA technology A high capacity and cost effective integrated system for offshore...

GaAs thin-film photovoltaic technology achieves record 28.9% efficiency

On paper, GaAs (gallium arsenide) thin-film photovoltaic energy has a 33.5% maximum theoretical efficiency, the so-called Shockley-Queisser limit. In other words, it is capable alone, without concentration of light or semiconductor seconds, to transform more than a...

The concrete roof that absorbs solar energy and transforms it into electricity

At the Swiss Federal Institute of Technology in Zurich, a prototype of a smart and sustainable home is being developed, which will have a concrete roof that absorbs solar energy and turns it into electricity. Flexible, light and eco-sustainable. This is how the houses...

A new solar project to beat the record of the giant Noor Abu Dhabi

Abu Dhabi's massive 1.1 GW solar project is officially completed and underway, but the emirate has no roof, now announcing a new 2 GW power plant. Noor Abu Dhabi plant to sell produced energy for 2.4 cents per kWh By downloading the tweet, you agree to Twitter's...
