Is this fine by the Flemish government appropriate? As of January 2009, all new residential houses in Flanders must be audited by the Flemish Energy Agency (VEA). This is to ensure that energy use is kept within appropriate limits. Houses are rated according to their so-called E-level, which must be less than 100 to receive… » read more

A view on nuclear energy!

One year ago, Commissioner Piebalgs stated: “Nuclear is here to stay!“. The trends, indeed, point in that direction: several European countries are withdrawing their nuclear embargoes and planning nuclear power plants! Leonardo ENERGY has interviewed Jean Van Vyve, the responsible for nuclear generation at Electrabel, discussing some limitations and advantages of nuclear Energy. The resulting… » read more

Concentration photovoltaics (CPV) offers one of the most promising utility-scale, renewable energy technology options. Many companies are testing their CPV products and some have already launched commercial offers. This documentary presents interviews with some industry representatives present at ISFOC (CPV Institute in Puertollano, South of Spain).

How sustainable is electricity?  What is the best technology to produce it? These questions are often asked and the answers are not clear-cut. Leonardo ENERGY has produced this eco-sheet to help clarifying the issue. The environmental burden of generating one kWh from 7 different energy sources is quantified. It shows that there is no silver… » read more

Improving technology, expansion off-shore, and exploring the building sector potential   The wind sector has been growing spectacularly over the past decade. However, to sustain these impressive growth figures over the next twenty years in Europe and North America, business-as-usual will not be enough. In several European countries, the number of remaining onshore sites for… » read more

Environmental impact of the PV life-cycle   All means of electricity generation, including photovoltaic (PV) systems, create polluting emissions when the entire life-cycle is taken into account. In the case of PV systems, those emissions are concentrated in the manufacturing stage. PV manufacturing is energy intensive, resulting in the emissions that accompany the use of… » read more

The wind energy industry is booming worldwide, favoured by ambitious targets for renewable energy, various subsidy mechanisms, and rising prices for fossil fuels. This does not mean however that wind companies have struck gold. A wind development project is a complex affair with many barriers and one requiring favourable climatic and geographical conditions that are… » read more

In countries like Germany, Denmark, or the Netherlands, wind power is already so widespread that few on-shore sites are left on which new units can be built. Two main paths are being followed to further increase the electrical power generated by wind: building off-shore wind parks, and replacing existing wind turbines with new and larger… » read more

Bart Franken & Erwin Hoeskma from Kema explain what regulators need to consider in establishing an effective voltage quality regulatory framework for distribution networks. In particular, they consider the regulation of five voltage quality dimensions: short interruptions, voltage dips, flicker, supply voltage variation, and harmonic distortions. Their work assesses the most appropriate regulatory control method… » read more
