What are 3 alternative sources of energy?
Solar power Takes energy from phtons emmitted from the sun. Hydro power Takes power from currents of water turning a turbine. Nuclear power Splits atoms to release energy
What are the energy conversions which takes place in such power stations using fuels to generate electricity?
Chemical energy to thermal energy to mechanical energy to electrical energy
Is hydro power renewable energy source?
yes, hydro-power is considered a renewable energy source because it is easily gained and easily "re-made". Other Examples of this is biomass, geothermal energy and windpower. non-renewable energy is considered anything that takes a LONG time to make, like millions and billions of years! an example is oil, coal or natural gas.
What do you need to generate electricity?
It takes energy to generate electricity. Mechanical energy or thermal energy or nuclear energy , chemical energy,etc, etc,etc
What energy changes takes place at the hydro electric power station?
Gravitational potential energy in the water is converted into mechanical energy by turning turbine "blades", the mechanical energy (kinetic energy) is converted to electrical energy by the electric generator.
What takes the most energy to generate microwave or ex ray?
An X ray takes more energy to generate because it is higher frequency (second in shortest wavelength only to gamma rays). Microwaves are just higher frequency radio waves.
Is coal a renewable resource used for the generation of electricity?
Wind, solar and hydro are currently used to produce power. Hydroelectric being the most common and useful of the three methods.
How does a geothermal power plant get energy?
A geothermal power plant gets energy from the heat deep below the surface of the earth. Shafts are drilled down, often as deep as several kilometres, one to pump water down to the hot rocks, and another nearby which will allow the heated water (or steam) to rise up. This steam is then used to spin electricity turbines to generate electricity.
Why is nuclear energy used more widely in countries that have meager energy supplies?
bcz when nuclear rxn takes place energy is released in vast amount comparable to any other sources which can generate energy in any form
What does energy payback time mean?
You need energy to make a solar panel. Put it on your roof and see how long it takes to generate that same amount of energy. That's the energy payback time.Energy payback time means the length of time that a solar panel (or other device) will take to produce that same amount of energy that was used to make it.This is used with renewable and non- renewable energy solutions to describe how long it takes for the device to generate the amount of energy that it took to make it in the first place. It can also be used to measure the amount of energy your save by using an energy efficient device.payback time = total costs/ total saving or money made or energy produced per year. You can thing of payback time in both economic and energy terms - how long it takes to pay back in money terms the costs, or thinking about the costs being the energy needed to produce the device.A wind turbine's energy payback time is about four months. The estimated life of a wind turbine is about 25 years.Devices like:solar panelswind turbineswater turbinesgeothermal power plantsbiofuel plantsbiomass power plantswave and tide power plants
When rubbing hands together what energy takes place?
When we rub our hands, we use our body's energy to generate kinetic energy. This causes friction between our hands, which causes heat to be produced. Hence we feel warm.
Which is better geothermal energy or hydroelectric power?
Hydroelectric power is betters because it takes longer to run out geothermal energy goes away faster.
