When generating renewable energy and feeding it back into the grid ( in participating countries such as the US and Germany ), producing households are typically paid at least the full standard electricity rate by their utility and are also given separate renewable energy credits that they can then sell to their utility, additionally ( utilities are interested in buying these renewable energy credits because it allows them to claim that they produce renewable energy ).

When feeding young, adults will hammer off the heads off large insects to make them easier to consume, and remove the gut from caterpillars so that the tannins in the gut will not retard the chick's growth.

When climbing up the trunks of trees they do so in the manner of a woodpecker, and when feeding on the ground they hop instead of walking like the true Hoopoe.

When feeding on carrion, marabou frequently follow vultures, which are better equipped with hooked bills for tearing through carrion meat, and may various wait for the vultures to cast aside a piece, steal a piece of meat directly from the vulture or wait until the vultures are done.

When feeding the short dark green legs give it a characteristic ' low-slung ' appearance.

When beached or in shallow water the tiller was moved to the lower hole, the blade rope was slackened and the rudder head pulled up so the rudder could operate in shallow waters.

When the wave enters shallow water, it slows down and its amplitude ( height ) increases.

When mating in the spring, they are more often found in shallow rivers, creeks, and streams.

When estuaries contain very shallow sills, tidal oscillations only affect near surface waters to sill depth, and waters below sill depth may remain stagnant for very long periods of time, resulting in only an occasional exchange of the deep water of the estuary with the ocean.

When fishing in shallow water for smaller pike, lighter and smaller lures are frequently used.

When a wave enters shallow water it Wave shoaling | shoals, that is, it slows down and the wave height increases.

When waves pass over shallow areas, they shoal, as shown in the diagram at the right.

When the city abandoned the non-pressurized zanja system for a pressurized pipe system, these smaller, shallow reservoirs located at low points no longer provided much benefit.

When he arrived there he saw his wives wading half-way across the shallow channel which divided Naroongowie from the mainland.

When the job is finished we see a Navajo ( Johnny used Sol Worth to play the part of a Navajo ) walking up to the well and drawing water and we see water coming from the various parts of the shallow well.

When viewed from below it resembles the shallow concave shape of a saucer.

When an outflow boundary forms due to a shallow layer of rain-cooled air spreading out near ground level from the parent thunderstorm, both speed and directional wind shear can result at the leading edge of the three dimensional boundary.

When initially copying an object, a ( fast ) shallow copy is used.

When humans drive motor boats over shallow seagrass areas, sometimes the blade propeller can tear out or cut the sea grass.

When surface waves move towards shallow water, such as a beach, they slow down, their wave height increases and the distance between waves decreases.

When the Oresund fixed link was eventually built in the 1990s, it was routed 1 km south of Saltholm to avoid damaging the island and the surrounding shallow waters.

When not breeding, the birds use a wider range of shallow wetlands, such as irrigated fields, lake margins, and mining subsidence and other floodlands.

When feeding on small crabs the Royal Tern does not use its normal plunge-dive technique, but instead uses short shallow dives so that they are concealed from their prey.

When the waves reach the narrow and shallow Neva Bay, they become much higher — ultimately flooding the Neva embankments.

The nest is an untidy shallow bowl, made of sticks and usually placed on a leafy branch 5 – 12 m high, at altitudes from sea level to over 1000 m. When breeding the birds have long feathers ( nuptial plumes ) on the neck, head and back.

When STD is used, the depth of discharge is often what would be considered shallow, and extensive damage to the seafloor can result due to covering by the tailings product.

* When the bag is used in shallow water and surge or wave action causes rapid changes in dynamic loading, by pulling the bag from side to side

When the organism dies its shell is deposited on the shallow sea floor and buried over time to create the limestone sedimentary rock of the lithosphere.
