Research by TU Delft proves that Dutch power stations are able to cope at any time in the future with variations in demand for electricity and supply of wind power, as long as use is made of up-to-date wind forecasts. PhD candidate Bart Ummels also demonstrates that there is no need for energy storage facilities. Ummels will receive his PhD on this topic on Thursday 26 February. Wind is variable and can only partially be predicted. The large-scale use of wind power in the electricity system is therefore tricky. PhD candidate Bart Ummels MSc. investigated the consequences of using a substantial amount of wind power within the Dutch electricity system. He used simulation models, such as those developed by Dutch transmission system operator TenneT, to pinpoint potential problems (and solutions).

Cranking up the heater or throwing on an extra sweater are two ways to cope with a drafty house that allows chilly air to seep in through cracks, doors and windows. eeting of Passive House California organization, free and open to the public: When the sun blazes in the summer, that same house warms up rapidly, prompting people who live there to close the shades or drapes, pour an icy beverage and possibly flip on an air-circulating fan.

The strangest and longest battle of the American West was fought not between early settlers and Indians but between two collectors of fossils. The Bone Wars, as the bitter clash became known, raged in the shadow of remote cliffs, in desert encampments, in university laboratories, and on the pages of academic journals.
