Pushing the efficiency limit of solar cells further
Pushing the efficiency limit of solar cells further
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.

Michael Blunk: "These are the challenges to be faced by the wind power of the future"
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.
Heat from the Centre of the Earth
Heat from the Centre of the Earth
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.
Grey Water to Heat My Home
Grey Water to Heat My Home
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.
Power from the Islands
Power from the Islands
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.
The End of Fossil Energy
The End of Fossil Energy
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.
Growing Ecologic Buildings
Growing Ecologic Buildings
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.
Harnessing Solar Energy
Harnessing Solar Energy
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.
