Making food and drink production for more than 500 million people more eco-friendly is a key policy in Europe. About 99% of all agro-food companies in the European Union are small and medium size enterprises (SME).

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.

Dealing with sludge is one of the biggest issues of waste water treatment.

The quest for energy efficiency has become a modern mantra. But developing new energy sources and production methods is not sufficient.

Increasingly, many of the plastic products we use every day are no longer based on petroleum raw material . Instead, they are made from biomass such as starch, sugar, corn and other sources that also happen to be food products.

Liberalising the heat market is, in theory, possible. It would operate in the same way that enables owners of domestic-scale wind turbines, or any other electricity producer, to sell surplus into the grid and draw power from the network.

A researcher who is using nanotechnology on the active layer of organic solar cells is Dr.

Some laboratories have achieved impressive efficiencies under concentrated sunlight. SunPower Corp. is much closer to the market. The California-based company recently produced a record-setting 24.

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.

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.

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.

Geothermal energy has always been used by man, but it wasn’t until the late 19th century that geothermal energy was “rediscovered” and used on an industrial scale.

Ecostiler “Energy efficient Community Stimulation by use and Integration of Local Energy Resources” is aiming to develop energy efficient communities thanks to the use of locally produced biogas and district heating systems.

In the spring of 2004, construction began on what is probably the most revolutionary project Högsåra in Finland has ever seen. This initiated a very special type of island adventure.

Certain European cities are a step ahead when it comes to preserving the environment. For instance, thanks to innovative techniques and a more ecological way of life, the commune of Växjö, Sweden, could be on its way to becoming the first fossil fuel free city in the world.

Reducing the energy requirements of buildings is an absolute priority in Europe. The energy demonstration project SARA has developed several public-access eco-buildings in France, Italy, Slovenia, Spain, UK and Uzbekistan.

One good way of helping the environment is to put what we call ‘solar panels’ onto the roofs of buildings. When the sun is shining these panels trap the rays and turn it into electricity and heat.
