Renewable electricity

The transition from fossil fuels and raw materials to sustainably generated electricity takes time and money. We’re therefore developing technologies to generate electricity from solar and wind more cheaply and more efficiently.

Cheaper and more effective electricity from solar and wind

Increasing renewable electricity is essential, but challenging. We’re developing technology for cheaper and more effective solar and wind energy.

22 November 2022

Solar heat can make an important contribution to increasing the sustainability of our heat supply. Photovoltaic-thermic (PVT) systems on the roof can, in combination with a heat pump, supply homes with heat and hot water. This would make natural gas redundant, thereby decreasing carbon emissions. There are plenty of options, but what about the cost-benefit analysis?

Solar energy is developing at lightning speed. The increase in efficiency is, amongst others, causing a cost reduction. TNO researchers, Eindhoven University of Technology and Delft University of Technology broke two world records on next generation so-called four terminal tandem devices (stack of two solar cells / sub-cells resulting in a better utilization of the energy in the solar spectrum).
