How useful are wind turbines?
The wind turbines is a machine that converts the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, The machine is usually called a windmill. If the energy is then converted to electricity, the machine is called a wind generator, wind turbine, or wind energy converter.
What percentage of energy is converted into useful energy?
It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.
What is solar heaters useful for?
Solar heaters are useful for heating water with natural energy, thus saving electricity. The question is can effective solar heaters be made for less cost than using the electricity.
Can you make a sentence using the word useful?
It was a useful object to use. It was not useful to the team to have to struggle with the new machine.
What is a dam How is it useful to us?
A dam is used to make an artificial lake in a river which can be used to generate hydroelectric power or as a reservoir.
Why is a tsunami useful?
Tsunami is useful to generate electricity.
Which makes photovoltaic systems especially useful?
They generate electricity......
What makes electricity such a useful form of energey?
the thing that makes electricity such a useful form of energy is that electricity is renweable it comes from the skies "thunder" you can also generate electircity but still some things need electricity to help it generate. so......... electircity is a useful form of energy, but also wind, solar are also useful for of energy.
How computers useful in data generation?
Computers are data processing machine. They don't generate datas.
What can be used to generate electricity but are useful only when the wind blows consistently?
wind turbines, wind mills.
What is the Useful energy transfer when coal is burned?
When coal is burned, the useful energy transfer is in the form of heat, which is typically used to generate electricity in power plants. The heat produced by burning coal is used to heat water and produce steam, which then drives turbines to generate electricity.
Why do we need gravitational energy?
Gravitational potential energy stored in the water reserved in a dam becomes useful to generate electricity.
What has to happen to the raw materials before it can be used to generate electricity?
It must be burnt and then compressed to get all of the useful energy out. Then the energy let out is measured in joules and used for electricity.
What are useful and non-useful energy transfers in the production of electricity using coal?
Useful energy transfers in the production of electricity using coal occur when heat from burning coal is used to generate steam, which drives turbines to produce electricity. Non-useful energy transfers include heat lost through exhaust gases and in the cooling process of the power plant, which reduce the overall efficiency of the energy conversion process.
What are some useful properties of current electricity?
Some useful properties of current electricity include the ability to power electronic devices, generate heat through resistive heating, create magnetic fields through electromagnets, and enable the transmission of information in communication systems.
Which fuel is more useful than piped gas?
Natural gas is THE most useful fuel there is. You can fuel vehicles with it, run home heating and cooking systems, use it in industry, generate electricity with it, and even make it into things.
How is electricity useful and dangerous?
Electricity is useful because it...... * Runs the air conditioner * Runs the stove * Runs the computers * Runs the phones * Runs the washing machine Electricity is dangerous because it can kill you if you get shocked by too many volts worth.
