Life is LiFi in smart buildings
Just imagine: you get back home one evening, unlocking your door with the torch light of your mobile. You sit down on your sofa, download a film 100 times faster than currently possible and enjoy the movie on a fully secure wireless connection.
How supergrids can support the integration of renewable energy
How supergrids can support the integration of renewable energy
In the past, most electricity grids were mainly based on centrally produced power, in relatively few plants, within national borders.

Nobel laureate Rae Kwon Chung speaks about the advent of HVDC supergrids
Nobel laureate Rae Kwon Chung speaks about the advent of HVDC supergrids
Both European and Asian experts are focusing on the challenging tasks of system integration and transmission of renewable energy over long distances. High Voltage Direct Current (HVDC) grid technologies could be the solution.
The City for Tomorrow
The City for Tomorrow
A new research conducted by world leading emissions experts is painting a rather gloomy picture. Due to stronger economic growth, global greenhouse gas emissions have hit a new record high of 37 billion tonnes of dioxide in 2017.
Approaching energy crowdfunding with eyes wide open
Approaching energy crowdfunding with eyes wide open
In 2016, for a few hours, all of Germany ran only on renewable energy , demonstrating that one day, the release of carbon dioxide into the atmosphere could really be avoided.
Households poised to become energy dealers
Households poised to become energy dealers
Households and small businesses using independent power systems, or microgrids, still find it hard to cope without their national electricity grids.
Green crowdfunding: disruption or opportunity?
Green crowdfunding: disruption or opportunity?
Crowdfunding is considered by some experts to have the same effect on banks as Uber has on taxis. Green energy crowdfunding is no exception: the process is 100% digital and lets everybody become an investor or request funding for a sustainable project, without going throughthe banks.
Could renewables crowdfunding assist “unplugged” Africa?
Could renewables crowdfunding assist “unplugged” Africa?
Over 640 million Africans have no access to energy, which means over 60 percent of population. At the same time, the continent has abundant renewable energy sources that could fuel its energy revolution.
District heating: has its time come?
District heating: has its time come?
From the frosty reaches of Umeå in eastern Sweden to the rolling hills of San Sebastian in Spain’s Basque Country, European cities have one refrain on their minds as the cold sets in: winter is coming and homes must be heated in a way that allows the EU to reach its goal of reducing energy consumption by 20% by the year 2020 .

Engineer and project manager Michael Blunk, Fraunhofer Institute for Wind Energy and Energy System Technology IWES, is one of the experts in the European project UpWind. The aim is to develop a new type of turbine.
When will solar power become competitive?
When will solar power become competitive?
Competitive solar cells rely on climate, efficiency, material and production costs. The fluctuation of electricity prices from different sources and political climates both play a big part as well.
The Waltz of the Mirrors
The Waltz of the Mirrors
90% of the world’s population lives less than 2,700 km from a desert. If less than 1% of the world’s deserts were used to concentrate solar power, enough electricity could be produced to supply the entire planet.
