Introduction Wind power has been around for decades, but it’s only recently that it’s become cost-effective compared to other types of renewable energy. Wind turbines work because wind turns the blades of a turbine, which turns an electrical generator inside the tower. Wind power is one of the fastest growing sources of renewable energy in the world: there are currently…
Introduction We’ve all heard of countries that are investing heavily in wind energy, but did you know that Denmark gets 40% of its power from wind? And even though the US only gets about 5% of its electricity from wind, it is still one of the top producers and consumers of wind energy on a per-capita basis. In fact, there…
Introduction Wind turbines are large machines, and they’re built to work most efficiently at certain wind speeds. That’s why many people believe you need a constant 20-mph wind speed in order for a turbine to produce anything meaningful, but that’s not entirely true: The difference between low winds and high winds is not night and day — it’s more like…
Introduction Wind energy is a relatively new technology, but it has a long history. Wind turbines have been around for decades, and people have been using the wind to power mills and pumps since the Middle Ages. The oldest wind turbine in the world dates back more than 2000 years ago; however, it was not used to generate electricity like…
Introduction Wind turbines are a popular means of generating electricity. While they’re not as efficient as solar panels or other sources of renewable energy, they do provide an easy way to make your home more environmentally friendly. But what exactly is a turbine and how does it work? Wind turbines use the wind to generate electricity. Wind turbines use the…
Introduction Q: which country is first in wind energy? A: denmark produces 42% of its electricity by using wind turbines. Q: which province has more number of wind turbines in Canada? A: ontario with 1614 operational wind turbines. Q: how many turbines are currently in the world? A: more than 600,000. Q: how much energy does one medium size turbine…
Introduction Wind power is one of the oldest sources of energy, with evidence dating back to 2000 BC. The earliest references to windmills can be found in ancient writings from China, Persia and Egypt. The first European reference dates back to at least the 8th century AD while the first known American windmill was built sometime between 1630 and 1660…
Introduction It is no secret that we need to find new ways of generating electricity. Our current methods are limited and not sustainable for the world in which we live. Wind energy is one of the best ways to generate electricity because it is environmentally friendly and renewable, but there are other benefits as well. Here are some reasons why…
Introduction Wind energy is a clean, renewable resource that can be harnessed to generate electricity for homes, businesses and industries. In fact, wind energy already avoids nearly 150 million metric tons of carbon dioxide emissions each year – the equivalent of taking nearly 32 million cars off the road! Wind energy is clean because it doesn’t emit air pollution or…
Introduction Wind energy is a great way to help reduce your carbon footprint, but what about the impact on the environment? Is wind energy clean? I’ll address some common questions about wind power and help you determine if it’s right for your home. Wind turbines are very quiet. Wind turbines are very quiet. They are no louder than a typical…
