Definition 1. Can use rising and falling tides to create electricity 2. Build dams across narrow inlets a. As tide comes in, spins. How do energy conscious people feel about wind power? They were blown away. Renewable Resources Unit 8. Electricity The production of most electricity depends on a spinning turbine which is connected to a generator made up of. Alternative Energy -To achieve a future where energy use is sustainable, we must make the most of the energy sources we already have and develop.
The difference between the biomass and fossil fuel The vital difference between biomass and fossil fuels is one of time scale. Biomass takes carbon out of the atmosphere while it is growing, and returns it as it is burned. If it is managed on a sustainable basis, biomass is harvested as part of a constantly replenished crop.
This is either during woodland or arboricultural management or coppicing or as part of a continuous programmer of replanting with the new growth taking up CO2 from the atmosphere at the same time as it is released by combustion of the previous harvest. This maintains a closed carbon cycle with no net increase in atmospheric CO2 levels. Biomass was the first fuel mankind learned to use for energy. Pyrolysis : Heating the biomass can produce pyrolysis oil and phenol oil leaving charcoal.
Digestion : Bacteria, in an oxygen-starved environment can produce methane. Fermentation : Bio-material that is used to manufacture Ethanol and Biodiesel by an anaerobic biological process in which sugars are converted to alcohol by the action of micro-organisms, usually yeast.
Solid Fuel Combustion : Direct combustion of solid matter. Biomass to Biogas It can be found on every square meter of the earth as seaweed, trees or dung. Biomass production can often mean the restoration of waste land e. An estimated million tons of waste that goes to landfills could be used for energy production. Capturing methane from producers such as cows or rice fields and applying it for fuel will significantly reduce this greenhouse gas.
Biomass Future Advantages? Tidal Generator Tidal stream generators Tidal barrages Dynamic tidal generators Requirement of land. Density difference predictability The company Atlantis Resources is to install a 50MW tidal farm in the Gulf of Kutch on India's west coast, with construction starting early in The station started its commercial operation in This oscillating water column OWC produces about kw of power.

One of two energy flows not coming form the sun. Tags: geothermal power tidal. In general, the deeper we go into the earth, the hotter it gets. This gives a temperature increase of ? C K. Plenty hot for electric generation. Can also use shallower hole for space heating. Similar to low head hydroelectric. It was built in However, tides are totally predictable, so we can plan to have other power stations generating at those times when the tidal station is out of action.
