Question:and what are its advantages and disadvantages? : D

Answers:conventional- fossil fuels (petroleum, natural gas, and coal) disadvantages: Burning fossil fuels adds to global warming and produces sulfur emissions, acid rain, and smog; they are nonrenewable sources of energy nonconventional- Solar energy Wind energy Hydroelectric energy Geothermal energy Ocean energy Fuel cells Nuclear energy advantages: are renewable sources of energy

Question:how tidal energy is utilized? how wind energy is utilized? how solar energy is utilized? how biomass is utilized? what are their energy resources in the philippines? what are their advantages and disadvantages? please answer it now please i need it please i need it immediately... thank you=)

Answers:Geothermal electricity is renewable. Binary-Cycle Power Plants Hot geothermal fluid and a secondary (hence, "binary") fluid with a much lower boiling point than water pass through a heat exchanger. Heat from the geothermal fluid causes the secondary fluid to flash to vapor, which then drives the turbines. Because this is a closed-loop system, virtually nothing is emitted to the atmosphere. Dry Steam Power Plants Steam plants use hydrothermal fluids that are primarily steam. The steam goes directly to a turbine, which drives a generator that produces electricity. This is the oldest type of geothermal power plant. It was first used at Lardarello in Italy in 1904, and is still very effective. Flash Steam Power Plants Fluid is sprayed into a tank held at a much lower pressure than the fluid, causing some of the fluid to rapidly vaporize, or "flash." The vapor then drives a turbine, which drives a generator.


Answers:Wind and solar can generate enormous amounts of energy with only minimal negative environmental, social, and economic implications. These sources do not pollute or deplete natural resources and therefore can sustain energy supply for generations, if not indefinitely.

Question:i need to know this for my test review please help? and i need an example for each i have three though im not sure if their right so help please and thanks? i have : solar energy:solar pannels, putting gardens on roof tops wind power: wind mills hydro power: niagra falls

Answers:St. Joseph's Center deals with Power Supplies. We are happy when focus is given to environment friendly Power Units. In this regard, one can consider Solar Energy panels (actually called photovoltaic cells) that generate up to 1000 watts of energy per meter squared in sunlight. Wind turbine generators are useful in open areas of land that have no other use. They generate useful energy that can be stored in lead acid accumulators in remote areas. Hydroelectric power generators have been the standard source of clean, env. friendly power for many years. A single dam with a hydel unit can suppy many cities with power. Tapping power from waves and tide that comes in at the sea shore is another useful source of energy that is being studied today. The British are working on a project in this field. Movement is a source of power. In the Automatic Wrist Watch, the movement of the hand is converted into a winding force that keeps the watch wound and working throughout the day. Bacteria convert decaying matter into useful gases that can be used for cooking. In my electronic project for SJRTC in Rajagiri College in Ernakulam of Kerala, India, I was pleased to find natural gas was being used in the hostel mess stoves to prepare meals for us. The natural gas is produced when bacteria ferment the decaying organic materials in an nonaerobic condition. These are standard and time tested methods of power supply which is non-conventional.
