Wind Energy

Wind is a sustainable source of energy

Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling. Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions.

An individual wind turbine has a relatively small physical footprint. Groups of wind turbines, sometimes called wind farms, are located on open land, on mountain ridges, or offshore in lakes or the ocean.

How wind turbines work

Wind turbines use blades to collect the wind’s kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces the electricity.

Advantages of Wind Energy

1. Green

Wind energy is a green energy source. Harnessing wind energy does not pollute the environment nearly as much as fossil fuels, coal and nuclear power do.

It is true that the manufacturing, transportation and installation of a wind turbine contributes to global warming slightly, but the electricity production itself does not involve any emissions of climate gases whatsoever.


2. Enormous Potential

As mentioned in the introduction of this article, the potential of wind power is absolutely incredible. Several independent research teams have reached the same conclusions: The worldwide potential of wind power is more than 400 TW (terawatts).[1]

Harnessing wind energy can be done almost anywhere.

3. Renewable

Wind energy is a renewable source of energy. Wind is naturally occurring and there is no way we can empty the energy resources. Wind energy actually originates from the nuclear fusion processes that take place on the sun.

As long as the sun keeps shining (don`t worry, according to scientists it will for another 6-7 billion years)?, we will be able to harness wind energy on earth. This is not the case for fossil fuels (e.g. oil and natural gas), which our society relies heavily on today.

4. Space-Efficient

The largest wind turbines are capable of generating enough electricity to meet the energy demand of 600 average U.S. homes.[2] The wind turbines can`t be placed too close to each other, but the land in-between can be used for other things. This is why many farms would benefit more from installing wind turbines as opposed to solar panels.

5. Rapid Growth

Although wind power only accounts for about 2.5% of total worldwide electricity production, the capacity is growing at an incredible rate of 25% per year (2010).[3] This does not only contribute in the fight against global warming, but also helps lowering costs.

6. Prices are Decreasing

Prices have decreased over 80% since 1980.[4] Thanks to technological advancements and increased demand, prices are expected keep decreasing in the foreseeable future.

7. Low Operational Costs

It is generally true that operational costs tend to be low once the turbines first have been manufactured and erected. However, not every wind turbine is created equal – some are more susceptible to maintenance than others.

8. Good Domestic Potential

People can generate their own electricity with wind power in much the same manner as people do with the best solar panels (photovoltaics).

Net metering (currently implemented in more than 40 states across the U.S.[5]) allows homeowners to receive bill credits for their excess electricity production There is good money to save/earn with residential wind turbines, but maybe the best perks come from not being reliant the utility for electricity, which can protect you from blackouts as well as fluctuating energy prices.
