                                   Wind Energy


             Formation and damage of wind energy


 How wind energy is formed  and Used. wind turbines convert kinetic energy in the wind  into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. wind energy is gaining popularity around the world.                            

 although wind power  plants have relatively little impact on the environment compared to fuel power plants, concerns have been raised over the noise by the rotor blades, visual impacts, and deaths of birds and bats that fly in the rotors.                                                   

                    How wind energy works    


                              Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller like blades around a rotor is connected to the main shaft, which spins a generator to create electricity. wind turbines operate on a simple principle.

                Risks of wind energy


 Accumulating ice can fall or be thrown from turbines, potentially endangering surrounding people and property. There are also more subtle health risks of wind farming. ... The sub-sonic noise generated by turbines is believed to cause maladies ranging from headaches and sleeplessness to dizziness and even depression.The same researchers concluded that a more accurate estimated range was 140,000 to 328,000 deaths per year due to wind power tower and turbine collisions. ... A recent study estimated that between 89 million and 340 million birds die annually in vehicle collisions on US roads.Wind turbine blades do indeed kill birds and bats, but their contribution to total bird deaths is extremely low, as these three studies show. A 2009 study using US and European data on bird deaths estimated the number of birds killed per unit of power generated by wind, fossil fuel and nuclear power systems.

Taiga ecosystems

Image
Location of the Taiga Ecosystems The  taiga  is the largest biome. The  taiga  is primarily a coniferous forest (evergreen trees with needles) like the temperate rainforest, but the  taiga  is  located between 50 degrees latitude north and the Arctic circle. The  taiga  is a forest of the cold, subarctic region. The subarctic is an area of the Northern Hemisphere that lies just south of the Arctic Circle. The  taiga  lies between the tundra to the north and temperate forests to the south. Alaska, Canada, Scandinavia, and Siberia have Taiga. Climate The  taiga  is the terrestrial biome with the lowest annual average temperatures after the tundra and permanent ice caps. ... The  taiga  or boreal forest has a subarctic  climate  with very large temperature range between seasons, but the long and cold winter is the dominant feature. Plants There are some lichens and mosses, but most  plants ...

littoral zone ecosystem

Image
Littoral Zone Location The littoral zone or nearshore is the part of a sea, lake, or river that is close to the shore. In coastal environments, the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged.                                      Climate of littoral zones The air and water  temperature  can range from extremely hot to below freezing to moderate. The average range of air  temperature  is from 75°f to 102°f. The  intertidal zone  does have seasons. The inter tidal  zone  has hot and humid summers, moderate springs and falls, and cool harsh  winters.                                                         ...

River and Streams by Yuridia and Briana

River and Stream Ecosystem in this ecosystem we are going to talk about river and stem ecosystem.it will talk about all sorts of plants and animals Animals : Some of the animals that live in the river or streams are  turtles, ducks, otters, crocodiles, catfish, drag on fly and crabs can be found in  rivers  all around the world, and the Amazon river is even home to the rare and pink, freshwater dolphin. an d for your information we are talking about all rivers and streams   climate: Rivers change their course as they travel and carve a path through the land.  The temperatures range from 65 °F to 75 °F in the summer and 35 °F to 45 °F in the winter. plants: Rivers and streams  are fresh water and hold up to 3 percent of the Earth's fresh water. Freshwater  plants  include algae, bulrushes and cattails, and freshwater animals include crayfish, fish and eels. location: Rivers /  Streams : A...
