Are Wind And Solar Energy Worth The Effort?
Renewable energy will undoubtedly play a part in our future. But incorporating technologies like solar panels and wind energy into our outdated electrical grid is tough, and some say not worth the cost just yet. Trace explains why, and if those naysayers have any merit.
Emissions and Costs of Power Plant Cycling Necessary for Increased Wind and Solar Calculated
" New research from the Energy Department's National Renewable Energy Laboratory (NREL) quantifies the potential impacts of increasing wind and solar power generation on the operators of fossil-fueled power plants in the West."
Turbines, Generators and Power Plants
"Thermal power plants have big boilers that burn a fuel to make heat. A boiler is like a teapot on a stove. When the water boils, the steam comes through a tiny hole on the top of the spout. The moving steam makes a whistle that tells you the water has boiled. In a power plant, the water is brought to a boil inside the boiler, and the steam is then piped to the turbine through very thick pipes."
How does a hybrid car work?
"We are all familiar with gasoline-powered cars, and most people have heard about or seen electric cars. A hybrid car is a combination of the two. A hybrid vehicle contains parts of both gasoline and electric vehicles in an attempt to get the best of both worlds."
World Record Solar Cell with 44.7% Efficiency
"The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells."
