Your Questions About Wind Energy Turbines How Much Energy Produced

adminsta answers:

There’s a lot of carbon that goes into the production but it’s that way with any big machine. We need energy and every type out there will require some form of machine to capture and convert it into a form we can use.

As a whole, wind is reasonably clean. It’s just not very cheap. Those turbines take a lot to make. Hydro still is probably the cheapest and most reliable environmental source. Wind and solar get pretty flaky in certain environments. That’s not to say that one can’t make good use of them in certain places. Hydro and geothermal are excellent alternatives in other spots.

Methane recapture is probably the best option we have at this point. Capturing methane from decaying material has great potential given the number of people on the planet generating waste. Efficient capture and conversion need to be improved, but that’s happening now.

The first thing is a voltmeter
the second thing an ammeter

here are some schematics for displays

these provide very crude information, 3 and a half digit display is far superior but more complicated

You would learn more if you did your own homework.

adminsta answers:

They generate lot’s of power dude.

adminsta answers:

The rated output of the turbine, 2 kW, occurs at a specific wind speed. As long as the wind is blowing at the design wind speed, the turbine will produce 2 kW of power and 2 kWh of energy after one hour in a steady wind. Don’t get the terms power and energy confused with one another.

It’s different all over Africa. There are deserts and jungles. In the south it snows in the winter.

adminsta answers:

Mostly because it’s a very inefficient system; renewable energies, as of current technology, do not provide even nearly enough power for a single home, and far from it for, say, a group of flats. Also, *building* solar panels, for example, isn’t free or ecological: it would take several years’ worth of the world’s production of aluminum and heavy metals, and create enormous pollution, just to produce enough to replace nuclear power. Most people wouldn’t be happy at all to drastically cut their standard of living by not having enough energy.

But there is an idea to that, though just wait a few years, until someone figures out high-powered, tiny turbines!

The car battery is charged with power, as KW over a period of time, which is onergy as KWh. The motor is rated as power in KW, and uses power over time as energy in KWh. The power used by the motor varies however. Depends on how much acceleration, wind resistance and so on. It is minimal while cruising at a moderate speed, maximum when accelerating hard. You can assume it won’t exceed the maximum power rating for more than a few seconds.

The battery has to provide enough KWh for running the motor over a desired period of time/distance. Often the figures for cars are quoted as distance run (range), but even so the energy used depends on the number of stops and starts and the speeds used.

The power to recharge depends on the efficiency of charging (chemical efficiency and the electrical efficiency of the charger). Allow something like 130% of the energy used to get the battery recharged.

The link below has some figures like range (all electric) 40 miles, battery 16KWh, and recharging takes 8 hours or 3h with bigger power supply. From this we can assume:

The average energy usage is 0.4KWh per mile or 2.5 miles per KWh. This is something like 4.8c per mile from the grid in the US.

It takes 21KWh to recharge, and that is over 8 hours, so the charge power is 3KW or less over a period of time totalling to 21KWh, taking at least 8 hours. A 3KW wind generator is likely about 18 to 20 feet diameter, not all that small. It will only generate this power in significant (I should say strong) winds. It is likely to produce about 1KW average over a period of time in a region that is “good for wind”. It does nothing until the wind speed exceeds a threshold, then increases as the wind speed.

In reality these figures may be different because the battery may not be fully discharged ever (toi ensure its life is long). This may mean only 8KWh is ever used or replaced in the 16KWh battery.

adminsta answers:

You wouldn’t technically be producing energy, but you would be converting the mechanical energy of your arms to electrical energy. A wind turbine is just an electric generator attached to some fan blades. The wind spins the fan which turns the generator. When the generator turns magnets inside it turn and push electrons through coils of copper wire – that movement of electrons is electricity. You could also hook the same generator up to your bike and do the same thing.

Additionally, an electric motor is just an electric generator run in reverse. Electrons move through the wire which create a magnetic field which spin the magnets which cause the axle to rotate. Since your ceiling fan has an electric motif in it, manually spinning the fan will indeed generate electricity.
