Social, green, but primarily as an investment: all the features of energy crowdfunding
Social, green, but primarily as an investment: all the features of energy crowdfunding
There are three ways a crowdfunding project can be financed. Lending: the entrepreneurs borrow money and pay interest; equity: investors in the project become its shareholders; donations: no reward is to be expected (there is a fourth way, a mix of equity and lending called “hybrid”).
Gauging public opinion on small wind turbines
Gauging public opinion on small wind turbines
Recent studies suggest that around 70 to 80 percent of people in Europe support wind farms, although there are still concerns around noise and aesthetics.

Gone with the wind farms – Six of the world’s top offshore arrays in pictures
United Kingdom - London Array With a peak rated power of 630 megawatts, London Array is the largest wind farm in Europe by capacity, and also the largest offshore plant in the world.
Energy crowdfunding: the new way to boost renewables
Energy crowdfunding: the new way to boost renewables
It's a brand new sector: the first steps date back to 2012. Today energy crowdfunding is a way of financing solar panel or wind turbine projects.
The small wind turbines you’ll want in your back yard
The small wind turbines you’ll want in your back yard
Opponents to wind turbines often claim that the noise and vibrations from the turbines affect their health , leading to sleep disturbance, headaches and a host of other problems.
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.
Dressing the power lines to bring more renewables to the cities
Dressing the power lines to bring more renewables to the cities
To date, European consumers pay more for energy from renewables than for energy from conventional resources. One of the reasons is still the immaturity of the technology used for harnessing and distributing renewable energy.
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.
Clean energies in need of a long term vision
Clean energies in need of a long term vision
The European grid already faces transmission challenges, as the alternative current (AC) infrastructure has almost reached its transport capacity.
The way to more efficient, quieter wind turbines
The way to more efficient, quieter wind turbines
It may sound strange to anyone who lives in the vicinity of one or more wind turbines, but wind currently represents just  4.5-5% of the renewable energy supply in the world.
Wind turbines: new device to reduce noise and increase efficiency
Wind turbines: new device to reduce noise and increase efficiency
Noise pollution is one of the main public concerns associated with operating wind turbines. To tackle this problem, technicians at a Spanish windfarm near Burgos are assembling a new device on the blades.
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.
Mitigating the impacts of extreme weather
Mitigating the impacts of extreme weather
Extreme weather events such as heavy rainfall, storms, floods or forest fires can considerably damage roads, railways, communication systems and power lines.

Alan O’Connor - Taming nature’s wild character
Flash floods in Central Europe in 2002 damaged hundreds of roads, caused electricity failures, contaminated clean water and cost an estimated €150 billion in damage .
Energy efficient building in the public eye
Energy efficient building in the public eye
The heating and cooling of buildings take a large share in the energy consumption in Europe . The average energy consumption in the non-residential sector, such as public and industrial buildings, is estimated to be at least 40% greater than in the residential sector.
Laurence Rouïl - policymakers now trust air quality models
Laurence Rouïl - policymakers now trust air quality models
Air quality is a public health issue. As recently as last October, the World Health Organisation classified global outdoor air pollution as ‘ carcinogenic to humans .
Forecasting air pollution
Forecasting air pollution
Air quality is not a local problem. Like clouds moving through the sky, pollution is transported from one location to another by wind patterns in the atmosphere .
