Sometimes it may seem as though there's little to no profit in doing good. That may not be true as often as you think it is, however. It certainly is not true when it comes to investing in wind power. As searching for renewable sources of energy becomes more imperative, wind power has become a booming business. Your investment can not only benefit your portfolio but the earth itself. Here are some important and exciting things you should know about wind energy before you decide to invest.

1. It's Happening More Off-Shore

2. It's Considered a Stable Investment

3. You Can Turn To Familiar Names

4. Wind Energy Is Growing Fast

In the United States, the wind energy industry generates $10 billion of revenue every year. Wind power is growing so exponentially that by 2050, it may be able to meet the energy demands of one-third of the global population. From 2000 to 2006, wind power quadrupled its global generation.

5. Operational Costs Are Practically Nothing

Obviously it costs money to put up the turbines. However, after that point, there is little in the way of operational cost because the wind needed to power it costs nothing. Tax incentives from the government and technological advances help to keep the upfront costs associated with wind turbines low.

6. Wind Energy Produces No Water or Air Pollution

Burning chemicals to produce energy to turn traditional turbines sends carbon emissions into the atmosphere. You may know this already, but you may not know that traditional electricity generation methods involve tons of water to cool down the mechanical processes. Wind power does not involve burning any fossil fuels, nor does it require any water. Therefore it produces no pollution and is expected to save approximately 30 trillion bottles of water in the United States alone by the year 2030.

7. Turbines Come in Different Sizes

Small turbines are reserved for individual houses and businesses. They can stand alone to provide all the necessary power, or they can connect to the grid to provide a back-up. Large turbines can generate multiple megawatts, enough to power hundreds, and possibly thousands, of homes. There may be investment opportunities available involving either large or small turbines.

8. Wind Power Is Not a New Idea

People have been harnessing wind energy to apply in different ways for millennia. It's propelled sailing vessels, ground grains, and pumped water for irrigation, a use to which it has been put for at least 4,000 years.

Wind power itself is nothing new. What is novel is the increasingly creative and efficient ways that human beings have developed to harness it and put it to good use. Where there is ingenuity, there is opportunity to invest in something that, in this case, everyone stands to benefit from.
