1. Denmark to create world's first energy island in the North Sea

Denmark approved a plan on Thursday to build the world's first energy island in the North Sea that will produce and store enough green energy to cover the electricity needs of 3 million European households.
The artificial island, which in its initial phase will be the size of 18 football fields, will be linked to hundreds of offshore wind turbines and will supply both power to households and green hydrogen for use in shipping, aviation, industry and heavy transport.
The energy island, which will cost around 210 billion Danish crowns ($33.9 billion) to build, is an important part of Denmark's legally binding target to cut greenhouse gas emissions by 70% by 2030 from 1990 levels, one of the world's most ambitious.

The MoU was signed between Uttarakhand State Council for Science & Technology (UCOST) and National Council of Science Museums (NCSM), an autonomous organisation under the Indian Ministry of Culture.
The project will take four years to complete. The Centre will provide ₹88 crore while the state government will contribute ₹85 crore for the ambitious project
