The impacts of potential linear barriers such as roads, highways, and power lines on rainforest fauna are poorly understood. In the central Brazilian Amazon, we compared the frequency of local movements (<300 m long) of understory birds within intact forest and across a 30-to 40-m-wide road over a 2-year period. Rainforest had regenerated along some road verges, to the extent that a nearly comp...
After developing the methodology, we applied it to case of Netherlands highways. We show that average irradiation on Dutch highway network is around 880 kWh/m2/y, 35% less than potential an optimally tilted conventional PV system in south Netherlands. Covering entire 1600 km highways with solar road modules poly c-Si, mono c-Si and CIGS would respectively generate 5.2 TWh/y, 6.6 3.4 TWh/y DC el...
