Money-saving small wind turbines: myth or reality?
Money-saving small wind turbines: myth or reality? Getting clean energy through your own turbine without relying on a central grid sounds great, but with subsidies being cut across Europe, is it too good to be true? Those with plenty of experience with wind turbines are quick to concede the financial challenges of this green technology.
Small wind turbines: navigating the ‘jungle’
Small wind turbines: navigating the ‘jungle’ Most EU countries enforce a legal obligation to only use wind turbines certified by an accredited organisation.

Reducing the cost of wind energy for a renewable future
Reducing the cost of wind energy for a renewable future In 2015 Denmark produced 42% of its electricity from wind turbines,  breaking the world record  of 39% that it set the previous year. But, this is only the beginning.
New erosion protection for offshore wind turbines
New erosion protection for offshore wind turbines The harsh offshore environment with heavy rain causes the  blades to erode , leading to a significant reduction in efficiency and energy production.
Wind energy costs approach nonrenewable levels
Wind energy costs approach nonrenewable levels All too often, conversations on renewable energy meander toward the same end: green technology is a nice thing, though it has to become economically viable before widespread adoption becomes the norm. ...
Smart grid: A grid suitable for renewable energy
Smart grid: A grid suitable for renewable energy Traditionally our electricity grids were designed to move power from large nuclear and fossil fuel power plants to consumers, but renewable energy will see changes to allow smaller power generation from wind and solar to be hooked up to the grid.
Building retrofits critical to Europe’s low-carbon pathway
Building retrofits critical to Europe’s low-carbon pathway From thatched roofing in cold regions to reflective walls in hotter climates, for centuries buildings have been constructed with materials that maximize comfort within a given environment.
Clean and affordable: the wind energy challenge
Clean and affordable: the wind energy challenge On 22 April , it is world Earth Day . The idea is to raise awareness of the need to rely on renewable energy. The EU requires its member states to provide a a 27% share of renewable energies by 2030—up from a 23.
Biogas from animal waste in need of maturity
Biogas from animal waste in need of maturity Livestock produces a lot of waste. One solution is to turn such agricultural waste into biogas to generate energy .  It requires using so-called anaerobic digestion, which consists in breaking down biodegradable material in the absence of oxygen.
