Qatar is making a special effort to have the 2022 FIFA World Cup go as green as possible. The country was elected as the host for the World Cup and is currently developing a state-of-the-art solar-powered cooling technology that will keep visitors cool and away from the Middle Eastern summer heat. The state is also developing stadiums incorporating modular technology for the tournament which will be disassembled after the World Cup completes. The seating will then be donated to countries lacking good sports infrastructure.

The world’s largest operational off-shore wind farm is busy churning out megawatts and powering up the UK grid with green and renewable energy. Called the London Array, the wind farm had its 175th turbine commissioned on Saturday afternoon and overtook the Greater Gabbard west farm, also in UK. The array has a capacity of 630 MW and was completed in December.

Being a technology big-shot isn’t easy, particularly when most of your research and manufacturing processes leave a dark carbon footprint on the environment around you. Well, Apple seems to have jumped aboard the green bandwagon and has taken a solemn oath to go eco-friendly. To show its commitment to the greener side, the company recently announced that 75% of its corporate facilities and data centers are now powered by renewable energy, thanks to the Apple’s newest development, pegged as the nation’s largest privately owned solar array.

As the world raises its head to solar power and embraces green energy, California will welcome home the world’s largest solar power towers. These will be developed by sustainable development company Abengoa and BrightSource Energy, a concentrating solar thermal technology company. The project called the Palen Solar Electric Generating System will include two 250 MW units located in a Department of Interior Solar Energy Zone in Riverside County.

Rural areas are usually detached from proper health-care facilities, causing a rise in the number of diseases and illnesses and the casualties that result from these. South Korean electronics giant, Samsung, has recently come up with solar-powered health centers that will cater to the people of areas as such. Samsung Electronics Africa unveiled its Solar-Powered Health Centre model in Cape Town as a kick-start to its large-scale medical initiative.

The state of Gujarat in western India has come up with a fantastic way to make use of free space to generate green juice. Up ahead, the Chief Minister, Mr Narendra Modi, will inaugurate an innovative project that simply works as a canopy over the Narmada canal. This canopy sports solar panels and works as a full-fledged array! Called the Canal Solar Power Project, the project could very well use the 19,000 km-long network of Narmada canals to its advantage.

Heat energy is usually given out during the generation of electricity. However, this energy is usually allowed to go waste, without being tapped into as an additional source of renewable energy. Recently, designers Shuguang Li and Xiaoping Chen decided to make the most out of this untapped energy source and came up with a Heat-electricity Conversion Storage Device. This device uses a thermoelectric conversion material to transfer and then store electricity from heat waste.

British designed and made micro turbine, the Urbine, looks set to take off. Ecotricity, Britain’s first green energy company, has turned towards micro wind turbines after the poor design and performance of regular wind turbines has threatened the future of wind energy as a reliable alternative energy source. The micro turbine should be up to 40% times more efficient than its bigger brothers, provided it passes the next six months of rigorous testing planned for it in the UK. Not only would its success give the wind energy sector an ego boost, but also the flailing British economy. It is estimated that in the last ten years, almost 12,000 jobs were created in this sector.

The Clean Wind Energy Downdraft Tower is a skyscraper-sized wind power plant powered by solar energy. It has close to zero carbon footprint, produces almost no waste and consumes virtually no fuel. By harnessing the power of the sun to make wind energy, it can be used in areas with little breeze of its own. It works like this: a fine mist of water is sprayed across the top of the hollow tower to cool hot air as it enters, as it cools, it falls more heavily and faster, so by the time it reaches wind turbines at the bottom, it is powerful enough to generate electricity. This first tower in Arizona could make up to 1000 megawatts of energy per hour, approximately 600 megawatts of which would go back into the national grid.

Inadequate transport, poor roads, soaring temperatures – these are just a few reasons why around 40% food in India spoils before it reaches a dinner table. What people in developed countries would throw in the dustbin with barely a thought, can lead to mass starvation or keep farmers living at poverty levels in India. To help combat this, business students, engineers and corporate in Ohio have put their heads together to address this issue, and come up with a very effective, but crazily expensive solar powered fridge-shed thingy that no small farmer in India would ever be able to afford! Priced at $5,000, the SolarCool runs on eight solar panels that can keep food chilled, even at night, thanks to a battery that gets charged in the daylight.
