How much are we willing to pay for renewable energy?

It’s easy for us to say we support renewable energy. But in practice, what is our willingness-to-pay (WTP) for it?

A key factor in whether a particular country or region is likely to reach its renewable energy objectives – such as the European Union’s goal to achieve a 20% overall share of renewable energy by 2020 – is how willing households are to migrate to its use from conventional energy.

An up-to-date analysis of the energy performance of PV systems

The long debate as to whether PV produces more energy than it consumes has been settled conclusively. It does.

A high energy return on energy investment (EROI) of an energy production process is crucial to its long-term viability. The EROI of conventional thermal electricity from fossil fuels has traditionally been viewed as being much higher than the EROI of renewable energy, and specifically of photovoltaics (PVs).

Advocating a more flexible home electricity installation

Today, most newly built or renovated private houses are still equipped with a rather simple electricity installation, providing not much more than a series of light points, switches and power outlets throughout the building. While this so-called base case electricity installation is very robust and safe, it is being challenged by the ever increasing expectations of 21st century homeowners and occupants.
