In traditional power plants, fossil fuels like coal, oil, or natural gas are burned to create heat. This heat is used to produce steam, which spins a turbine connected to a generator, creating electricity. In renewable energy systems, natural forces like sunlight, wind, and water are harnesse...
Furthermore, we restate the obvious fact that the investment climate in Sweden must improve if the wish is to avoid having coal‐based electricity production on the margin.αMats Nilsson, Lule University of Technology and Vattenfall R&D, and Kristian Gustafsson, Vattenfall R&D. Mats Nilsson is ...
Of course, using a generator to make electricity is just the beginning. After you get your electrons moving along, you'll need an electrical circuit to do anything with it. Find out why next.Electrical Circuits Batteries When you load a battery into an electronic device, you're not simpl...
electricity needs, less than the 31.7 percent that comes from natural gas and the 30.1 percent from coal, and only slightly more than the 17.1 percent provided by renewables such as hydropower, wind and solar [source: EIA]. But some countries depend on the atom more heavily. France, for ...
Also, some energy sources, such as the coal-burning power plants that generate nearly half of U.S. electricity, pour out carbon dioxide, which threatens to change Earth's climate in dangerous ways [source: Dosomething.org]. Energy vampires drain pocketbooks as well. In 2011, each American ...

There are currently more than50 million smart metersinstalled across the US. Although they’re helping people reduce electricity usage, it’s still not enough to reach the desired energy-saving goals. We need real-time energy consumption data. And that’s where technology comes into play. ...
As we've already discussed, a generator converts mechanical energy into electricity. A motor works on the same principles, but in the opposite direction -- it converts electrical energy into mechanical energy. To do this, a motor needs a special kind of magnet known as an electromagnet. In...
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...
PV converts sunlight directly into electricity. These solar cells are usually found powering devices such as watches, sunglasses and backpacks, as well as providing power in remote areas. Solar thermal technology is large-scale by comparison. One big difference from PV is that solar thermal power...
