How many homes can 1 MW power?
1200 California homesAs indicated in Figure 1, 1 MW of dispatchable capacity can serve about 1200 California homes if measured in terms of the electricity produced by an average MW in kilowatt-hours (kWh), or about 600 homes if the MW is measured at peak times.
What is the lifespan of a wind turbine?
20 yearsA good quality, modern wind turbine will generally last for 20 years, although this can be extended to 25 years or longer depending on environmental factors and the correct maintenance procedures being followed. However, the maintenance costs will increase as the structure ages.
Are small wind turbines worth it?
Small wind turbines are a reliable option, whether in the suburbs, living off the grid, or just trying to save costs. They offer sustainable energy that significantly minimizes your carbon footprint.
How many houses can a 2 MW wind turbine power?
60,000 homesThe project, which uses the 2 MW wind turbine platform, will eventually generate enough electricity to power 60,000 homes.
How big is a 3 MW turbine?
GE's 3 MW platform machines are three-blade, upwind, horizontal axis wind turbines with a rotor diameter ranging from 130 to 137 meters. The turbine rotor and nacelle are mounted on top of a tubular steel tower, with a range of hub height options that includes 85-, 110-, 131.4-, 134- and 164.5-meter variants.

The payback for the associated energy use is within about 5-8 months, and even in the worst case scenario, lifetime energy requirements for each turbine only takes 1 year of operation.
Why is it bad to build wind turbines?
One of their main arguments is that it takes so much energy to, for example, build wind turbines that the energy that is produced takes a long time to offset the energy used for production and installation, making them a worse deal than they seem, and thus not as beneficial to the environment as pro-renewable people claim.
