A potentially disruptive wind power innovation will begin a week-long trial at a Portuguese air force base before the end of April.
A 16-meter long helium-filled cylinder will rotate creating considerable lift force. A ground-based winch-generator will convert the lift force into electricity. Once the cylinder has reached its maximum height, its rotation is stopped and the module descends to its starting position.
During trials in April 2015, the airborne module will fly below 500m of height .
In a recent Energy Blog article we looked at the advantages of staying on the grid rather than going off it. Here is a different perspective.
The most cost-competitive way of providing electricity is generally considered to be central electricity generation with transmission and distribution (T&D). Such a grid works fine for most urban and densely populated areas of the developed world, but what about in rural areas in developing countries?
Becoming grid-independent is being increasingly seen as the ultimate in green self-sufficiency. But does it make economic sense?
Some people consider that there’s something inherently attractive about living “off the grid” – the ultimate step in going green. They are attracted to the idea of making their own electricity without having to rely on it being wired into the house from a power plant down the road.
A group of researchers thought it would be interesting and useful to conduct a survey of the research output over the last 20 years into renewable energy
With the growth of the renewable energy industry, the associated body of literature has grown substantially.
At about 10% of all EU energy use the scale of cost-effective energy savings and carbon reductions by proper application of building automation and controls is very large. To unlock this potential, there is no need for more EU regulation but rather to ensure MS implementation of existing regulations is in line with an holistic strategy to target this specific savings opportunity.
As we move into a world with increasing amounts of renewable energy on the grid, reliable, affordable and grid-scale energy storage systems are essential. Pumped hydro is one such system.
Hydro power is not only a renewable and sustainable energy source, but its flexibility and storage capacity also make it possible to improve grid stability and to support the deployment of other intermittent renewable energy sources such as wind and solar.
