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 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 Biofuel is a form of energy made from biomass, which is material that came from living organisms. The most common forms of biofuel are ethanol and biodiesel, both of which are used as transportation fuels. Biobutanol is another type of biofuel that can be used for transportation or electricity generation. It has several advantages over ethanol: it does not…
Introduction Biomass fuel is a renewable source of energy that can be used for heat, electricity and transportation. It can be made from a variety of materials like wood chips, corn stalks or manure. The only problem is that it isn’t always clear whether or not biomass fuel is actually sustainable. It might seem like biomass is a renewable form…
Introduction Are you considering using biomass to heat your home? Biomass is a renewable energy source that’s often considered carbon neutral because it takes carbon dioxide out of the atmosphere and releases oxygen back into it. But burning biomass can release harmful pollutants into the air, and some forms of biomass are better than others. Let’s look at what makes…
Introduction If you’re like most people, you probably think of hydropower as something that only exists in remote mountain streams. But did you know that it’s also used to generate electricity? Hydroelectricity is one of the oldest forms of renewable energy and produces more than half of America’s electricity. Here are three facts about this popular source: Hydropower is electricity…
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 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 Electricity is produced when a turbine (which looks like an oversized fan or propeller) rotates and its blades cut through the air. The wind turns the blades on their axis, which spins a shaft connected to a generator. This process creates electricity by turning magnets inside coils of copper wire as they pass by one another at high speed….
