Medium Size PV Plant

Recently, the competitiveness of Photovoltaic (PV) as opposed to other electricity sources has improved considerably. In many situations, PV systems represent a profitable and relatively low risk investment opportunity. Nevertheless, a case-by-case analysis should be performed to properly evaluate each project.

Energy and climate policy screening in comparison to the EU

This project evaluates climate and energy policies in non-EU countries and provides recommendations for policy opportunities in the country under study. However, the learning opportunity also goes the other way around - European Member States might learn from countries outside the EU.
Countries all over the globe are taking steps in the transition towards a sustainable energy supply.Read full article

People or places? Factors associated with the presence of domestic energy efficiency measures in England

We use English household-level survey data from 1996 to 2010 to explore whether economic market failures play a significant role in explaining the presence of energy efficiency measures (loft insulation, cavity wall insulation and full double glazing) in residential properties. There appears to be a limited role for credit constraints as proxied by income, receipt of means-tested benefits or educational attainment.

Sustainable Heating and Cooling of Buildings

In many non-residential buildings across Europe, the energy consumed for heating and cooling is more than half the total energy consumption of the building. This is not inevitable. The introduction of simple design concepts and currently available technologies can lead to significant reductions in the energy consumption, operating costs, and carbon emissions of both new and existing buildings.

Optimal cable sizing in PV systems: case study

It is often beneficial to over-size the cross-section of electricity cables compared to the standard values that follow out of voltage and current calculations. In the large majority of cases, oversizing has a positive influence on the Life Cycle Cost of the installation. The investment in larger cable is easily paid back by the reduction of Joule losses inside the cable and the subsequent savings on electricity bills.
