Hydro Power

No. Hydroelectric power is any power coming from water, usually from its movement, but also from its heat (thermal).

Hydrothermal power is power generated only from the temperature of the water (hot springs, ocean thermal, geothermal).

Yes because hydro-electricity relies on turbines which need to be turned round. In most cases, it is made from dams(made on rivers), which relies on water passing through it to turn the turbines.

Wind energy is the most commonly used alternative energy source in Texas. 79% of all renewable energy generated in Texas in 2006 was wind energy.

Hydroelectric power requires water. That means you can't put it just anywhere; you need a river. That's issue one. Issue two: you need a river with a suitable dam site. A river flowing through a deep narrow valley is ideal; a river meandering through a broad flat plain is less so. Issue three: you need to not care too much about the land upstream from the dam, since some of it is going to get flooded. Issue four: a dam large enough to generate a significant amount of power costs a lot of money. Buying the land you're going to flood may not be all that cheap either, since it's near a river; historically speaking, people tend to settle near rivers. So hydroelectric power has a fairly large upfront cost. Issue five: environmentalists are going to oppose it. You'd think they'd love hydro power since it produces no greenhouse gases, but it always turns out it's going to flood the habitat of the snail darter or the speckled pestilence fly or something and we certainly can't have THAT.

Most hydro power is used to generate electricity, which then replaces non-renewable energy from fossil fuels (coal, oil and natural gas).

hydro electric power has been believed to have said that it lasts for around 50-70 years

1.Water is collected at a certain height in huge reservoirs.

2.This water,which has lot of potential energy

3.The energy of falling water is used for generating electricity in hydro-electric power stations

4.In hydro-electric power plants turbines are used to convert the energy of falling water into mechanical energy

5.Hydro-electric power plants have least operating cost

6.They are free from environmental problem

Near dammed rivers, although it will be difficult to assure that some current flow does not derive from even a very distant hydroelectric generator.

people use hydroelectric energy to power almost anything from cars to ur hair dryier . But it is mostly used to power houses. basically people use it for electricity

Yes it does the engery is converted to electricity and then sent to your hones in power cables.

Main inlet valve or shortly we say MIV is the spherical valve which installed before water enter into spiral casing of the hydro turbine.Water from the dam go to the penstock and before water enter the turbine, MIV is a component in between stop the water for small maintenance purpose in the turbine hall

no no it is not

if u have air powers u can controll the wind.....

When there is not much demand for electricity, such as during the night, the extra electricity is used to pump water back up to a storage reservoir. Then, later in the day, when electricity demand is high, the water from the storage water is also released as an extra, producing more electricity when it is needed.

A British example of when this might be needed is when Downtown Abbey finishes and 2/3 of the viewers then go to make tea. Because Downtown Abbey has such a large audience, it is thought that a somewhat 5 million people then go to make a cup of tea [or coffee or hot chocolate or whatever] after the show has finished, thus creating a power surge. This would be an adequate excuse to use the pumped storage method of gaining energy quickly.

Solar Power

Contrary to popular belief, hydroelectric power can seriously damage the climate. Hydroelectric dams produce significant amounts of carbon dioxide and methane, and in some cases produce more of these greenhouse gases than power plants running on fossil fuels. Carbon emissions vary from dam to dam. in 1990 the greenhouse effect of emissions from the Curuá-Una dam in Pará, Brazil, was more than three-and-a-half times what would have been produced by generating the same amount of electricity from oil. This is because large amounts of carbon tied up in trees and other plants are released when the reservoir is initially flooded and the plants rot. Then after this first pulse of decay, plant matter settling on the reservoir's bottom decomposes without oxygen, resulting in a build-up of dissolved methane. This is released into the atmosphere when water passes through the dam's turbines. In effect man-made reservoirs convert carbon dioxide in the atmosphere into methane. This is significant because methane's effect on global warming is 21 times stronger than carbon dioxide's. With the proposed IPCC guidelines, tropical countries that rely heavily on hydroelectricity, such as Brazil, could see their national greenhouse emissions inventories increased by as much as 7%. Colder countries are less affected, because cold conditions will be less favourable for producing greenhouse gases. ................................................... But it doesn't make sense to me cuz If a tree falls in the woods, and there is no hydro dam for it to fall into, it's still going to rot and produce greenhouse gases. I'm sure that it produces different proportions of gases depending on what conditions it decays under, but it's not possible for rotting vegetation to put out more carbon/greenhouse gases into the air than it originally filtered out when it grew. So many clean technologies get marked as dirty because they are subject to unfair analysis. This seems to be happening all the time. We now find out that the Toyota Prius is actually quite bad for the environment because of the batteries and the extended manufacturing process.

We can never just be satisfied with what we assume is true about a power source or "green" product, we must always dig deeper to see what is really going on.

How a lemon lights up a LED light is lemon juice has acid (a.k.a acidic juice) so when u connect zinc and copper to the lemon since they are conductors energy will flow from the acid to the copper or zinc and then it will flow through wires and the energy will be transformed into light energy and will be used by the LED light.

One renewable source of energy is solar energy. You can get solar energy from using solar panels.

The Renewable Sources of Energy are:

Solar Power

Hydro Electricity

Wind Power

Biomass

Geothermal

No

They say that a man named Lester Pelton first used water to generate electricity, but the first hydroelectric plant didn't come into play until 1882, and it could only light 250 light bulbs.

As long as the rain keeps falling in the catchment area, hydro electricity is very reliable. It will run day and night if required, as the water is stored up behind the dam. If the rainfall is unreliable, then hydro electricity is unreliable too.
