The way to more efficient, quieter wind turbines

A European research project aims to reduce the cost of wind energy generation by introducing technical improvements to turbines, which will have to be much quieter in the future than is the case today

The precision of solar photovoltaic power measurements doubled

An analysis carried out by JRC scientists shows that the uncertainty in measurement of power generation from a photovoltaic (PV) cell can be more than halved, thus bringing an economic benefit to both manufacturers and investors. ...

How smart can the electricity grid be?

Opportunities will open for European citizens with more and more renewables on the European electricity system.

Inspired by art, lightweight solar cells track the sun

Solar cells capture up to 40 percent more energy when they can track the sun across the sky, but conventional, motorized trackers are too heavy and bulky for pitched rooftops and vehicle surfaces.

Probing the limits of wind power generation

(Phys.org)—Wind turbine farms now account for an estimated 3.3 percent of electricity generation in the United States, and 2.9 percent of electricity generated globally. The wind turbine industry is growing along all vectors, ...
