I found a great piece of property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. However, it would be nice to have at least a little electricity, since so much of life in the 21st ...
Globally, at least 50,000 wind turbines are producing a total of 50 billion kilowatt-hours (kWh) annually. In the next section, we'll examine the availability of wind resources and how much electricity wind turbines can actually produce. Wind-power Resources and Economics A Watt? Watt (W)...

In practice, wind turbines use different types of generators that aren't very much like dynamos at all. (You can read about how they work, more generally, in our main article about generators.)How does a wind turbine work? Wind (moving air that contains kinetic energy) blows toward the ...

a basic law of physics called theconservation of energytells us that a gas or liquid always slows down or changes direction when it flows past a turbine, losing at least as much energy as the turbine gains. Blow on the windmill stuck in your sandcastle and it spins around. What you can...
data can be used to answer the question: how long did it take in 1970 and does today in 2020 to produce as much metal as has been produced in the entire history before 1970, i.e. how long are the doubling periods (See model inAppendix). Table2shows that the doubling periods became ...
“We are on the verge of that, and it’s something we are very much doing at Neste to find the best solutions to make this an affordable, sustainable process,” Neste’s Perttu Koskinen says. “There’s a big transition in the whole energy sector, caused by climate change of course, ...
Most people can't afford to own a wind turbine, which can run thousands of dollars for a residential setup. But a recent innovation in the technology has made it much more accessible to the average consumer: You can now use a shrunken, plastic windmill to recharge your cell phone. It's...
A more technical name for a jet engine is a gas turbine, and although it's not immediately obvious what that means, it's actually a much better description of how an engine like this really works. A jet engine works by burning fuel in air to release hot exhaust gas. But where a car...
