Electricity is a secondary energy source. Electricity is the flow of electrical power or charge. Electricity is both a basic part of nature and one of the most widely used forms of energy. The electricity that we use is a secondary energy source because it is produced by converting primary sources of energy such as coal, natural gas, nuclear
A new MIT-developed microfluidic technique identifies electricity-producing bacteria. Microbes screened with the device could be used in fuel generation and bioremediation, among other uses. "The vision is to harness the most-powerful bacteria for tasks like running fuel cells or purifying sewage water," Kart explains.
The water in the core is heated by nuclear fission and then pumped into tubes inside a heat exchanger. Those tubes heat a separate water source to create steam. The steam then turns an electric generator to produce electricity. The core water cycles back to the reactor to be reheated and the process is repeated. Boiling Water Reactors

Renewable sources of electricity include wind, hydropower, solar power, biomass, and geothermal. Together, these sources generated about 20% of the country''s
The two types of water are placed in adjacent chambers separated by a special membrane. Due to the resulting concentration gradient, water diffuses across the membrane from the freshwater chamber to the seawater chamber. The buildup of water volume in the more concentrated region creates pressure that spins a turbine, generating
Producing Electricity from Water How does it impact the environment? A typical hydroelectric power can generate 0.5 lbs. of CO 2 per kilowatt-hour (compared to 0.6-2 lbs. for natural gas burning and 1.4-3.6 lbs. for coal burning). Some hydroelectric power plants can produce 2 to 3 times the greenhouse gases of natural gas burning plants!
