Wind and solar energy projects are growing at a respectable clip. But storing electric power for days when the air is still or when the sun goes down remains a challenge, largely due to cost. Now researchers are developing a new battery that could bring the price of storage to more affordable levels. They report their new battery that uses low-cost materials — sodium and magnesium — in ACS’ journal Chemistry of Materials.
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.”
The Institute for Energy Research (IER) is a not-for-profit organization that conducts intensive research and analysis on the functions, operations, and government regulation of global energy markets. IER maintains that freely-functioning energy markets provide the most efficient and effective solutions to today’s global energy and environmental challenges and, as such, are critical to the well-being of individuals and society.
Founded in 1989 from a predecessor organization, IER is a public foundation under Section 501(c)(3) of the Internal Revenue Code and is funded entirely by tax deductible contributions from individuals, foundations and corporations. No financial support is sought for or accepted from government sources.
The U.S. Energy Information Administration (EIA) collects, analyzes, and disseminates independent and impartial energy information to promote sound policymaking, efficient markets, and public understanding of energy and its interaction with the economy and the environment.
