how much power from a wind turbine?
27744
The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor. An average onshore wind turbine with a capacity of 2.5–3 MW can produce more than 6 million kWh in a year – enough to supply 1,500 average EU households with electricity.

Microhydropower systems usually generate up to 100 kilowatts of electricity. Most of the hydropower systems used by homeowners and small business owners, including farmers and ranchers, would qualify as microhydropower systems.

A typical bike generator can produce 100 watts. If you pedal for an hour a day, 30 days a month, that's (30 x 100=) 3000 watt-hours, or 3 kWh. That's less than 1% of what a typical family uses in a month (920 kWH). You generated 0.3% of your energy, and continue to get 99.7% from the grid.

Sizing Small Wind Turbines A typical home uses approximately 10,932 kilowatt-hours of electricity per year (about 911 kilowatt-hours per month). Depending on the average wind speed in the area, a wind turbine rated in the range of 5–15 kilowatts would be required to make a significant contribution to this demand.

Wind. Wind was the second largest renewable energy source (after hydropower) for power generation. Wind power produced more than 5 percent of global electricity in 2018 with 591 GW of global capacity (568.4 GW is onshore).

400 Watt HAWT With 3.6 m/s winds, the 400W turbine generates 50W. Assuming it runs 24/7/365, the turbine will generate 438 kwH per year. The national average electric rate in the US is $0.12/kWh, so the turbine saves the owner $52/year in electricity cost.

Wind turbines under 100 kilowatts cost roughly $3,000 to $8,000 per kilowatt of capacity. A 10 kilowatt machine (the size needed to power a large home) might have an installed cost of $50,000-$80,000 (or more).

China – installed capacity 221GW China is the world leader in wind energy, with over a third of the world's capacity. It boasts the world's largest onshore windfarm in Gansu Province, which currently has a capacity of 7,965MW, five times larger than its nearest rival.

A 5 kW rated wind-turbine can cost anywhere between $15,000 (total cost with shipping, installation, inverter, mast, building permits, and electrical work) and $25,000.

The generator in a wind turbine produces alternating current (AC) electricity. Some turbines drive an AC/AC converter—which converts the AC to direct current (DC) with a rectifier and then back to AC with an inverter—in order to match the frequency and phase of the grid.

In Australia, installed small wind generators are usually 'rated' in the range of 1-10kW but small systems also include turbines of up to 100kW.

How it works. Wind power stations use the wind to turn a turbine which turns a magnet inside a coil (a type of generator). The wind has kinetic energy (Movement energy) which is changed into mechanical energy by the blades on the turbine. The turbine then turns a generator which creates electrical energy (voltage).

Hydroelectric power is the cheapest source of renewable energy, at an average of $0.05 per kilowatt hour (kWh), but the average cost of developing new power plants based on onshore wind, solar photovoltaic (PV), biomass or geothermal energy is now usually below $0.10/kWh.

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