Profiles Of Wind Energy In Use

Wind generated electricity is the second most popular type of commercially available renewable power in North America, right after the massive hydro-electric dams found in the West. However, the profiles of wind and other types of energy currently in use suggest that wind and solar will be taking off very significantly in the next few years.

Nearly every country on Earth has regions that use wind energy, and they are all growing at about 15% per year. Nations without access to oil reserves are increasingly aware of the advantages to using wind energy as a significant portion of their power generation budget. As a general rule, the countries with the most solar and geothermal power are which countries use wind energy, too.

Historically speaking, the use of wind energy has been for very specific purposes. That includes windmills for grinding grain or pumping water. Contemporary uses of wind power use a turbine to output alternating (AC) or direct currents (DC).

Today, larger turbines and generators almost always generate AC, which greatly expands the uses for wind energy directly from the generator. By way of comparison, only the very largest of solar plants actually generates an alternating current without the use of an electronic inverter.

For many households, the technology becomes of practical use when the installation of wind energy hardware is only as difficult as the typical satellite dish. Solar panels have found a better reception by neighbourhood councils and associations, because they don’t move and make noise.

In the past some confusion about how to use wind energy was caused by people simply not knowing what to do with a DC output and an intermittent action. However, now that net metering allows consumers to sell the generated electricity back to the grid in several states (and the cost of battery and flywheel storage has come down) using wind energy becomes less of a concern than how much you want to invest in future energy savings.

Other modern uses of wind energy include direct applications on farms, ranches, remote stations, street lamps, parking meters and developing nations. As a producer of regular 120V AC as it comes out of your wall, wind energy uses kinetic energy that is already in infinite supply to generate power. As technologies improve and become less bulky, the materials and cost necessarily go down, making it a great deal closer to that tantalizing dream of free energy.
