The two biggest reasons for using wind to generate electricity are the most obvious ones: Wind power is clean, and it's renewable. It doesn't release harmful gases like CO2 and nitrogen oxides into the atmosphere the way coal does (see How Global Warming Works), and we are in no danger...
The real magic isn't that power plants turn fuel into electricity: it's that even small amounts of fossil fuels contain large amounts of energy. A kilogram of coal or a liter of oil contains about 30MJ of energy—a massive amount, equivalent to a good few thousand 1.5-volt batteries!
a new idea that’s becoming adopted around the world as a way to stitch renewable energy into the grid. The system draws energy from distributed sources like battery storage or small rooftop solar panels and coordinates those sources to increase supply when electricity demand peaks. As a result,...
Globally, it has been evident that coal followed by gas is the largest source from which electricity gets produced. Which energy causes the least pollution? Solar energy causes the least air or water pollution or greenhouse gasses. Also, while in the process of harnessing and utilization, it le...
The engine spins all this torque through the driveshaft into the high-voltage generator. The electricity produced is then sent to the four massive electric motors, located in the trucks. The Trucks: Propulsion & Suspension The trucks have several jobs. HowStuffWorks The trucks are the heavies...
Figure 1. World per-capita consumption of oil, coal, electricity from nuclear power plants, based on data from the 2024 Statistical Review of World Energy, published by the Energy Institute. Most of us remember the Great Recession of 2007 to 2009. With a declining supply of what used to be...
Even though a light bulb doesn't generate greenhouse gas, the power plant that generates the electricity used by the light bulb probably does. Switch from incandescent light bulbs to fluorescent bulbs, which use less energy and last longer. Recycle. Garbage that doesn't get recycled ends up ...
Wind turbines generate electrical power from the wind and functions in the reverse manner as a fan does. Micro hydroelectricity is another source of energy, which fascinatingly “uses a source of running water, like a stream, to generate electricity” (Dunn 3). Between all three sources of ...
How does a nuclear power plant work? Okay, we've figured how to get energy from an atom, but the energy we've got isn't that helpful: it's just a huge amount of heat! How do we turn that into something much more useful, namely electricity? A nuclear power plant works pretty much...
